Exeem "Successor" to Suprnova Announced
Exeem "Successor" to Suprnova Announced: "Exeem is pretty much what was rumored earlier: a blending of the tracker, the BitTorrent client, and decentralized indexing. It's Windows only. It's in beta now, and will be out at some indeterminate date in the future."
LokiTorrent fights MPAA legal attack
LokiTorrent fights MPAA legal attack: "The latest peer-to-peer site to come into the legal crosshairs of the motion-picture industry promised this week to fight, and put out a virtual hat to finance its legal fund.
LokiTorrent, a Web site and index of files available through a peer-to-peer technology known as BitTorrent, posted a letter from the Motion Picture Association of America (MPAA) on its site on Tuesday. The letter states that the MPAA has filed suit in district court in Texas against the site and demands that Loki Torrent cease linking to video files that could infringe on studios' copyrights."

The BitTorrent Effect
Wired 13.01: The BitTorrent Effect: "Movie studios hate it. File-swappers love it. Bram Cohen's blazing-fast P2P software has turned the Internet into a universal TiVo. For free video-on-demand, just click here."
BTSlave
BTSlave BTSlave is a “slave repeater”. A BitTorrent repeater is a client that only downloads data when no one is interested in the data it already has. Repeaters can achieve very high upload/download ratios, and they help the other peers in a torrent download faster. The “slave” part means that the repeater has as it's main goal helping out it's “master” -- your usual BitTorrent client.

Formatting table in BTQueue
BTQueue 0.0.18 allows all you to specify your own table layout very easy. Basically, BTQueue has 3 tables for displaying brief information of torrents, connected peers, and all possible peers. The last table of all peers is introduced in version 0.0.18 to help you to verify the tracker action. This post aims to give you an overview to modify these format to meet your need.
First, you have to know the basic. A table consists of a set of columns. What you can do is to rearrange column order, hide some of them, justify alignment, and cut too long text. Technically, a column can be represent by its alignment, optional maximum length, and its column name in form cd,ssss or c,ssss. c represents alignment where l and r stands for left and right, respectively. d is an optional number to limit maximum length of this column. In case of a column is longer than the limit, it will be cut off. The next field, ssss, is the column name.

Rsync wrapper for windows
Rsync wrapper for windows provides a zip including rsync, cygwin, ssh, and their dependencies.
WINrsync
WINrsync: "WINrsync is a frontend to rsync. That means it shows a nice window with buttons and stuff, and lets you browse an rsync server and stuff like that. When you have finished setting all the options you want and click 'Download', it will fire up rsync with all the options you selected. So you just point and click, and let WINrsync do all the tough work remembering how to type all those options.
So, it doesn't add functionality. But it will let many more people use this genious way of transferring files."

Suprnova's eXeem beta review and screenshots
Mitosis Gold: Suprnova's eXeem beta review and screenshots: "Bit torrent websites are doomed. The trackers they offer make them nice, fat targets for the MPAA/RIAA and they're potential single pionts of failure due to hardware and/or bandwidth issues. Can P2P survive? Only if it evolves."
Quote of The Day
Australian IT - Hollywood struggles with BitTorrent (Alex Veiga in Los Angeles, DECEMBER 27, 2004): "'Someone else was doing something with BitTorrent that I had no knowledge of,' Mr Cohen said. 'It's not being done on any machines I have any control over...what do you want me to do?"

BitTorrent file-swapping networks face crisis
BitTorrent file-swapping networks face crisis | CNET News.com: "BitTorrent 'hubs' that publish lists of movies, TV shows and other free downloads suddenly went dark this weekend, in a major victory for Hollywood that highlights vulnerabilities in technology behind the world's busiest peer-to-peer network."
Man sentenced over movie sharing in Japan
Man sentenced over movie sharing in Japan: "
the Japanese legal system is as tough on swappping
films as the US, as far as tolerance goes. It seems the sentencing
phase goes a little bit lighter than the US. An individual using
the popular P2P program "Winny" was popped for the sharing of just two
films. We have seen already that the MPAA, at least in the US has a
zero tolerance level for file sharing, remember the Hulk? Unlike the
RIAA which has been targeting users that share at least 1,000 music
files.
Winny is a Japanese
peer-to-peer (P2P) file-sharing program, possibly the most popular one
of all over there right now. It gets it's name from
WinMX, where the M and the X are raised one letter in the alphabet, to
N and Y. Kind of like HAL the wayward computer from 2001 a Space
Odyssey, who's name was derived by shifting each letter down
from IBM. Oddly, Winny has a claim to fame for being able to hide a
users identity, but in this case it obviously didn't work. So we best
take that cloaking feature with a grain of salt
The
Kyoto District Court sentenced Yoshihiro Inoue, 42, for violating
copyright law for installing the program on his computer to let
internet surfers download "A Beautiful Mind" and "Unbreakable" last
year.
"This is a wicked crime which makes nothing
of the efforts of film makers," Judge Yasuhide Narazaki said. The
sentence was suspended for three years.
Whew,
that was a close one. But at any rate folks, just be aware that
trading these movie files is not too swift an activity. Maybe in some
countries, but not in the US and now even Japan.
If you would like to read more about Winny, which has a very interesting
history, please visit

Analysis of BitTorrent
The BitTorrent P2P file-sharing system | The Register: "Even though many P2P file-sharing systems have been proposed and implemented, only very few have stood the test of intensive daily use by a very large user community. The BitTorrent file-sharing system is one of these systems. Measurements on Internet backbones indicate that BitTorrent has evolved into one of the most popular networks [8]. In fact, BitTorrent traffic made up 53 per cent of all P2P traffic in June 2004 [12]. As BitTorrent is only a file-download protocol, it relies on other (global) components, such as websites, for finding files. The most popular website for this purpose is suprnova.org.
There are different aspects that are important for the acceptance of a P2P system by a large user community. First, such a system should have a high availability. Secondly, users should (almost) always receive a good version of the content they request (no fake files) [10]. Thirdly, the system should be able to deal with flashcrowds. Finally, users should obtain a relatively high download speed.
In this paper we present a detailed measurement study of the combination of BitTorrent and Suprnova. This measurements study addresses all four aforementioned aspects. Our measurement data consist of detailed traces gathered over a period of 8 months (Jun'03 to Mar'04) of more than two thousand global components. In addition, for one of the most popular files we followed all 90,155 downloading peers from the injection of the file until its disappearance (several months). In a period of two weeks we measured the bandwidth of 54,845 peers downloading over a hundred newly injected files. This makes our measurement effort one of the largest ever conducted.
The contributions of this paper are the following: first, we add to the understanding of the operation of a P2P file-sharing system that apparently by its user-friendliness, the quality of the content it delivers, and its performance, has the right mechanisms to attract millions of users. Second, the results of this paper can aid in the (mathematical) modeling of P2P systems. For instance, in the fluid model in [13], it is assumed that the arrival process and the abort and departure processes of downloaders are Poisson, something that is in obvious contradiction with our measurements. One of our main conclusions is that within P2P systems a tension exists between availability, which is improved when there are no global components, and data integrity, which benefits from centralization."

Torrent Site Status
Torrent Site Status: "The big reason for the recent witch hunts is because many bittorrent clients are slow to make changes to the BT protocol to decentralize bittorrent.
E-mail the author of the clients you use to add the 'get_peers/peers' extension to their clients. This removes the need for trackers beyond a single connection. (this means, if a tracker goes down, your transfers continue at full speed without issue)
Send the e-mail, as this will not happen until enough pressure is placed on the authors of BT clients. Force bittorrent to evolve!
XBT Client BitComet are the only clients that support this so far."
This referred extension seems to be popular in public tracker but banned in private tracker.

Gaim Filesharing Plugin
Downhill Battle - Downhill Battle Labs - Gaim Filesharing Plugin: "We propose an extension to the Gaim chat client that lets users do gnutella-style search & download filesharing, where search requests propagate out to trusted buddies, buddies of buddies, etc. This approach has serveral advantages. First, people will be more altruistic sharing with friends and won't be as worried about RIAA/MPAA lawsuits. At the same time, because they can share with friends-of-friends, and friends-of-friends-of-friends, they'll often be searching a very huge library. This software will be just as simple as an IM client, and it will be easy for people to invite friends (so it spreads virally). No other piece of filesharing software is this well positioned to become hugely popular with the average, not-so-knowledgeable, Windows user. As a bonus, it will convert many users to using the open-source and ad-free client Gaim--a good thing in itself. The immediate goal is creating a working version that is extremely simple but very modular and easy to modify or expand upon."
Blog Torrent - Simplified bittorrent by Downhill Battle
Blog Torrent - Simplified bittorrent by Downhill Battle: "Blog Torrent is software that makes it much easier to share and download files using the bittorrent protocol. Blog Torrent is easy to install on your website: we don't use MySQL so installation is as easy as uploading a folder to your web host, and all administration happens in the web interface. Blog Torrent is easy for users: even if they don't know what bittorrent is, they get an installer that downloads the file they want. But most of all, Blog Torrent makes publishing with bittorrent painless. Just click 'upload', pick a file, and you're done. This is our preview release and it has a lot of bugs and rough edges... but we're smoothing them out for the next version, so stay tuned."

Actual Transparent Window
Actual Transparent Window: Make transparent windows such as Taskbar, WinAmp and Menus in Windows 2000/Windows XP: "Actual Transparent Window is an innovative Windows transparency shell enhancement novelty - the application that allows setting any level of transparency for any individual window on the system.
Actual Transparent Window adds a new dimension to desktop space making it easy to organize simultaneously open windows without having to minimize and restore them every here and then. Along with common techniques of switching between applications windows Actual Transparent Window offers depth-based window ordering thanks to fully customizable transparency levels that are saved individually for each window.
Actual Transparent Window is intended for broad range of Windows users who value time and long for aesthetic pleasure of modern computing. Using transparent windows reduces negative effects on user's eyes as well as it allows for more native dimensional information representation model in human beings. Multiple reports by Actual Transparent Window users indicate overall increase of productivity when using several business applications that require manual information interchange simultaneously. Desktop space saved by eliminating opaque windows can be used for placing additional icons. Another great use of this program is for setting transparency depending on importance of task an application performs."

Long Term Storage
If
you don’t plan on using your notebook for more than six months, Apple
recommends that you remove and store the battery with a 50% charge. If
you store a battery when it’s fully discharged, it could fall into a
deep discharge state, which renders it incapable of holding any charge.
Conversely, if you store it fully charged for an extended period of
time, the battery may experience some loss of battery capacity, meaning
it will have a shorter life. Be sure to store the ejected battery at
the proper temperature.

Exeem
Slyck Forums: "Exeem is a new file-sharing application being developed by the folks at SuprNova.org. Exeem is a decentralized BitTorrent network that basically makes everyone a Tracker. Individuals will share Torrents, and seed shared files to the network. At this time, details and the full potential of this project are being kept very quiet. However it appears this P2P application will completely replace SuprNova.org; no more web mirrors, no more bottle necks and no more slow downs.
Exeem will marry the best features of a decentralized network, the easy searchability of an indexing server and the swarming powers of the BitTorrent network into one program. Currently, the network is in beta testing and already has 5,000 users (the beta testing is closed.) Once this program goes public, its potential is enormous."

Multiple commands in a single line
I have just modified BTQueue to allow specifying multiple commands in a single line separated by semicolon (;). This feature is also available in alias so you can write simple procedure by yourself. Note that you have to quote semicolon if you want it being interpreted as normal character like before. For example, see below alias.
super_detail will call detail followed by spew.
alias -s super_detail "detail %(arg1)s;spew %(arg1)s"
super_detail will call detail followed by spew.

Access Control List in BTQueue
Since 0.0.15, BTQueue allows us to limit access of incoming and outgoing connection at real-time with powerful user interface at least for me. Its idea is based on access control list in routers, firewalls, and programs, e.g. apache. Basically, there are only 2 access control lists available in BTQueue; allow and deny. Each access control list is a list of individual IP, IP range by prefix, IP range by netmask, country code, or network name separated by comma. See some samples below.
There are 2 special keywords to represent all IPs and none IP, ALL and NONE, respectively.
What you can do to limit access from someone is to choose the order of allow and deny depending on your requirement. One may want to allow some IPs and deny other ones. One may want to deny some IPs and allow other ones.
In order to specify ACL in BTQueue, you need to modify 3 options; order_acl, allow_acl, and deny_acl. By default, these options are defined as below.
If you want to ban all connections from Singapore, these options should be set as below.
In order to allow local connections only in Singapore, the options should be set as below.
For information about country code and network name, you should consule spew command or ip command.

JPype - Java to Python integration
JPype - Java to Python integration: "JPype is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines.
Eventually, it should be possible to replace Java with python in many, though not all, situations. JSP, Servlets, RMI servers and IDE plugins are good candidates.

Advanced firewall blocking technique
I have just encountered firewall problem. At the first sight, I don't think it is firewall problem. However, tcpdump told me what happened behide the scene. The situation is that I can get incoming connection from outside without problem but it seems to not work with real application. In fact, someone spoofs a packet to me with reset flag set. Oops!

DotGNU Portable.NET FAQ
DotGNU Portable.NET FAQ: "Why doesn't my C/C application work that I built with Visual Studio.NET?
Usually, the C/C applications that are output by Visual Studio.NET are not pure IL binaries. They contain x86 native code, and depend on all kinds of Microsoft-specific libraries. Such applications will never work with a pure-IL engine such as 'ilrun'.
Apparently there are switches that can be supplied to Visual Studio.NET that force it to output pure-IL binaries. But even then, there will still be dependencies on other Microsoft libraries. Your mileage may vary.
Some people have suggested interfacing 'ilrun' to Wine so as to pick up many of the Windows dependencies. This may work, but we need someone to volunteer to do it first.
If your application is written in C, and does not depend upon Windows-specific features, then you can recompile it using the C language front-end for 'cscc'. The resulting binary is likely to be more portable than that produced by Visual Studio.NET.
Update: more recent versions of Visual Studio.NET apparently generate IL that is more pure. Your mileage may still vary though."

Improve modularity with aspect-oriented programming
Improve modularity with aspect-oriented programming: "Aspect-oriented programming (AOP) is a new programming technique that allows programmers to modularize crosscutting concerns (behavior that cuts across the typical divisions of responsibility, such as logging). AOP introduces aspects, which encapsulate behaviors that affect multiple classes into reusable modules. With the recent release of AspectJ by Xerox PARC, Java developers can now take advantage of the modularization AOP can provide. This article introduces AspectJ and illustrates the design benefits that result from its use."

CX65
Eventually, I bought Siemens CX65 because many users reported lots of firmware bugs in C65 and wireless in X600 might not work perfectly with all IrDA. CX65 is more expensive than X600 just about 1000 baht so I decided to pay a little more to get the most stable mobilephone in the three candidates.

Siemens C65 or Samsung SGH-X600
I am making a decision to buy a mobilephone. There are 2 choices: C65 and X600. I like samsung but I don't like the external antenna. C65 seems to have better IrDA. X600 has a far better built-in VGA camera. I'm not sure that Easy Studio for X600 will work perfectly via IrDA on WinXP SP2.
However, I will buy one today!

Goodbye SGH-C100
After using Samsung SGH-C100 for about 6 months, it have gone forever. Today, I was driving my car and last time called it. I took it on my lap after hanged up. I drived for a while and got out of the car to get a thing in back door. Unfortunately, it fell down to the ground without any sound crack.
Suddenly when I noticed it was not in my pocket, I tried to call them hopelessly someone received and told me to get it back. I was really sad, nobody received in the first call. However, my phone had been turned off in the second call. Goodby my C100.

Calculating ratio for very strick tracker
In order to prevent cheating peer in closed tracker, there is a very easy solution to solve this problem. However, it might be too strick.
Problem: Some clients do not even try to contact tracker but they are still able to leech using historical peers information.
Solution: Count amount of download by size of the torrent immediately when download its metadata
Advantage: Disable cheating of unreporting clients
Disadvantage: Downloading only some files may not fair

Interesting tracker's promotions
BT is very popular and some trackers do not allow non-member to leech from them to guarantee share ratio of the whole system. Below are interesting promotions for closed tracker.
In addition, many users have tried to cheat the counting system. It is mostly impossible to prevent cheating due to BT protocol. That means tracker must track not only share ratio, but also list of who want to leech and who finished each torrent for cross checking.
- Bonus credit - give extra upload by amount of snatched
- Delay - do not allow low ratio users to leech new torrents
- Golden time - turn off delay and count download only a half

SCMSWeb as a replacement of MDS for job scheduling problem
Since MDS2 is very unstable and SQMS/G relies on it, sometimes SQMS/G can't get available resources due to timeout in MDS itself. To temporarily fix this problem, we decided to extend SCMSWeb to act like a MDS especially for SQMS/G.
To activate this function, you have to upgrade SCMSWeb to the newest version in CVS. Note that you have to upgrade all SCMSWeb instance in the grid. Next step, you have to specify your scheduler for job monitoring module in /etc/sce/sce.conf as follows.
Now SCMSWeb only supports SQMS, SGE, MDS, and RSL. If you are using other scheduler, you can use MDS or RSL if globus supports it. Actually, MDS and RSL are very similar but MDS may contain remote information.
In order to use MDS, you have to specify mds_host, mds_port, and mds_basedn in mds group.
For RSL, it is necessary to specify globus_location and scheduler_type in jobmon group.
Note that both MDS and RSL does not provide full information like native drivers such as SQMS and SGE.
In SQMS, I introduces new resource information plug-in for retrieving queue status from specified URL. If you want to activate this plug-in, please change option allhost_source in group sqms or queue's group to liburlrinfo.so. Moreover, specify option queue_url in form %scmsweb_cgiurl%/queue_mon.cgi by replacing %scmsweb_cgiurl% with cgi url specified to SQMSWeb at installation time (contact your admin). Default value is http://localhost/cgi-bin/scmsweb/queue_mon.cgi.
To activate this function, you have to upgrade SCMSWeb to the newest version in CVS. Note that you have to upgrade all SCMSWeb instance in the grid. Next step, you have to specify your scheduler for job monitoring module in /etc/sce/sce.conf as follows.

scheduler = sqms

[mds]
mds_host = mds.thaigrid.net
mds_port = 2135
mds_basedn = mds-vo-name=thai,o=grid
For RSL, it is necessary to specify globus_location and scheduler_type in jobmon group.
[jobmon]
globus_location = /usr/grid
scheduler_type = pbs
Note that both MDS and RSL does not provide full information like native drivers such as SQMS and SGE.

Daemon/Remote in BTQueue 0.0.16
Since 0.0.16 introduces many new features, I am trying to explain how to use it efficiently. The most requested feature is to run it in daemon/service mode. Prior to this version, you (and me) have to run btqueue incorperately with screen to make it run likely in background. Actually, only some of you might want this feature and all of them run btqueue on his/her server placed at ISP. BTQueue perfectly fit the need of administrators for remotely leech/seed on share server or office.
Today, you don't need screen anymore. All you want is just btqueue! However, old style btqueue is still preserved for short-term running. To run it as a daemon in the background, you have to specify daemon command.
After that, you will immediately return to prompt. Now you are ready to control btqueue anywhere by running command below:
By default, btqueue.py will bind itself on localhost (127.0.0.1) to make it more secure. However, sometimes you might want to control it from anywhere. In this case, please change global setting xmlrpc_ip to 0.0.0.0 or another more specific ip. As you should already know, there are 2 ways to modify setting; 1) directly modify policy.conf and 2) call gset command in the btqueue's prompt.
After modification, restarting is needed.
In remote control mode, you can do whatever you used to do. Note that notifications such as start and terminate are disabled in this mode. Moreover, quiting in this mode will not terminate its daemon. In case of you want to shut down the daemon gracefully, you have to run kill command instead.

Constructing a site board is painful
Today, I have bought a site board to place in my new room. It is so heavy (net wg. 40 kg). It took more than 3 hours to construct and it has not finished yet. The last pieces are to mount magnet to little door. I plan to buy a mini component very soon to put it in this site board.
Graphics Editor
Due to picasa can't modify image, I have to find another solution. What I want is just a small graphics editor that let me select a region in various form, rectangle, circle, or free form, and clear it to background color. This feature is very useful for posting screenshot with some private information. I found that Brush Strokes 1.01 meet my requirements. Its size before extracting is about 600 KB and 3 MB after extracting. However, as you could see it now, it is not a "good looking" program. Anyway, I will try to use it for a while.

QEMU is a processor emulator developed firstly on linux and later ported to windows. It allows to run windows on linux or linux on windows. This feature is very useful for linux live cd, e.g. Knoppix, to let me run linux without rebooting windows. However, it is slower than commercial emulator like virtual pc or vmware. Booting knoppix on qemu on windows is easy as single click.

It is very small in size but consumes huge memory (java vm). The best thing of FreeMind is that it is totally free for all and also includes sources (if you care). Another choice is MindManager which is a popular commercial mindmap software. It allows you to change style of line, node, and layout. Furthermore, you can export your map to powerpoint for quickly presentation in professional looking. In other words, it can also export the map to a document including your note. The output document is almost ready to submit as a technical paper! In addition, it supports task assignment like MS project and can synchronize with MS outlook. Cool!
Deploying tomcat and SQL 2000 on Windows Server 2003
This afternoon I deployed tomcat 5.0.28 and SQL 2000 SP3 on a Windows Server 2003. It took a while to download all of them via slow link. Fortunately, j2sdk is already available. WS 2003 consumes about 300 MB RAM at steady state.
Note that in order to run tomcat as a NT service, it provides service.bat in bin directory to install the service automatically. To install, just run:
And, to uninstall:
After that, I am able to start it by running "net start Tomcat".

Solution for remotely building distribution for btqueue
Eventually, I use cvsnt combining with openssh for windows as I mentioned earlier. Usually, I use TortoiseCVS but in this case, Tortoise doesn't work at all because it needs to interact via GUI. However, openssh is used as the ssh client for cvsnt only. Actual ssh server is WinSSHD which is much more easier to make it work on winxp sp2.
OpenSSH for Windows is incompatible with SP2
After installing 3.8.1p1-1 downloaded today, everything seems to work perfectly. Unfortunately, I can't find opensshd service in service list. I also tried to "net start opensshd" at prompt but no luck at all. It's the time to find another solution.
OpenSSH for Windows
Since I am having to release BTQueue 0.0.16 very soon, I am looking for a way to remotely create distribution on windows machine at office from my home. OpenSSH for Windows could be used here. It promises to allow running as a service at startup. However, this version, 3.8p1-1 20040709, was compiled on cygwin. It must be slow comparing to linux version.
SSHWebProxy - SSH via HTML
SSHWebProxy is a very interesting project aimed to enable users to access SSH shell and SSH file transfer using a web browser. It runs on JBoss.
SpeedswitchXP 1.4
%202004%20C.%20D.%2015%2010%202547%2010%2013%2010.jpg)
SpeedswitchXP is a battery optimized applet for winxp. It provides customizable policies to slow down processor speed for saving notebook run longer than normal policy controlled by winxp itself.
Testing hello
My Photo?
This is a test posting instant image using Hello. It is so easy but I don't know how to remove it. At this time, I know why hello should be used, it allows me to upload screenshot of current window or even the whole screen with single click! I love it.
QEMU CPU Emulator
QEMU CPU Emulator is a fast processor emulator. It claims to run winxp on linux host. I will try it very soon to make a win32 build machine for BTQueue.
SSH clients review
PuTTY was my most favorite ssh client for windows. However, it was unusable for a week without any error messages while other clients work fine. I noticed that the problem should be router setting at border gateway in my university. That's why I have to find a new client. PuTTY comes with sftp support but only text version available right now.
SSH Client has been widely used in my office because of its free license for educational use and its rich functionalities. Unfortunately, it seems so slow comparing to PuTTY. The biggest problem is that it does not support font encoding other than default one (ISO-8859-1 or latin-1). Another problem is HOME and END button do not work at all because it supports only a few terminal (no xterm and Linux). The best thing of ssh is that it cached passphrase for another concurrent session and also sftp.
SecureCRT is my current ssh client. It is fast and fully support publickey authentication based on key pair generated by openssh. SecureFX could be used as a sftp client sharing cached passphrase with SecureCRT. This feature looks like one available in SSH client but it is more powerful with synchronize button.

Day of Debugging
BTQueue 0.0.16 is going to be ready very soon. It is being tested by developer teams to download bittorrents from various trackers automatically. Today, BTQueue allows user to define aliases with unlimited substitution in each group. In additional, user-defined tracker allows user to dynamicly define pattern of tracker for automatic crawling via cron. For bandwidth shapping, it introduces new algorithm, I called it fair-share, to distribute transfer rate to all session in balance fashion. This action applies to both upload and download. Furthermore, seed rate is activated. In contrast, global upload rate = seed rate + upload rate.
SCMSWeb has been modified to announce resource manager contact string of each queue to its xml. This feature will be used in SQMS to replace MDS. Current, MDS is implemented by OpenLDAP which is very unstable for WAN and especially grid. The most problems are inadequate bandwidth and too high latency that lead to missing information due to timeout error.
