Gimme something to shoot

Coin, Hope you had fun during the holidays. For DC Admins too, it's now time to go back to work :-/ (laaaaaaaazyyyy). === PHP Cleanup === As already advertised, the following PHP obsolete "features" are now deactivated for ever: * register_long_arrays: $HTTP_*_VARS * register_argc_argv: $argc / $argv * magic_quotes_gpc: "magic quotes" === Elwing Rebirth === A month ago, one of Elwing's disk died. Unfortunately, he had no RAID at that time, and much was lost (but hopefully not so important data). After a few problems during the silly not-for-raid WD "desktop-class" disks saga, we recently came back to normal operation. As Elwing was long not very reliable, we changed a few things: * the XMPP node was moved to Thorfinn, so that redondancy is available again (and not behind an ADSL link) * our beloved bots moved to Thorfinn too That's another step towards proper DL/DC separation, and "nothing behind weak links" target. Please note Daneel had to be shutdown, to make use of his almost identical hardware in order to perform the migration. Backup is back since 2010-08-25. === Antispam Problems === Our antispam software (DSPAM) caught a sunstroke and had difficulties remembering what you taught him. It is work in progress since a few weeks, and we hope to have made improvements (even if the bugs probably caused learning problems in the past and results may not be visible very quickly). Stay tuned. More on several other topics later. -- Marc Dequènes (Duck)

Coin, === Toushirou is moving === Due to technical problems, the move had to be rescheduled, and is happening tomorrow evening. Beware of the short downtime. === Photos === You can find recent photos (mostly for the 10th Anniversary), in the gallery: http://photos.duckcorp.org/v/duckcorp/ Remember you can ask for a personnal photo directory. === User Wiki === We still lack documentation about the available services and how to use them, so you're welcome to contribute to the user wiki, especially starting from this page : https://users.duckcorp.org/index.php/AvailableServices \_o<~>o_/ -- Marc Dequènes (Duck)

A world of dust
by DuckCorp Admin Team 23 Jun '10

23 Jun '10

Coin, === Toushirou is moving === As you may know, Sivit, one of our sponsor, was acquired by Nerim, so we have to move this machine in another location (Equinix). Tomorrow evening, Hivane folks, Yok, and me, will work on this move, and Toushirou will be down a short time. Nothing critical would lack, but a few services will be unavailable (mostly web related, except webmail/webdesk which is elsewhere). === More memory === Toushirou has now more memory (4GB instead of 2) since 2010-05-29, and is working fine. As our stability problem seemes to be memory bound, it is probably a stopgap, but anyway this machine needed more, so this is a good and not so expensive evolution. === Recent problems === * 2010-06-04 ~11:10: due to electrical problems in the bay, Orfeo was down during about half an hour. * 2010-12-06: the main Elwing's disk died, so it was quite a pain in the ass, as this machine had no RAID yet, but we managed to repair it quickly; nevertheless the disks or something in the OS is not working well, and we have horrible performance. It should not affect DC's services too much, as most of them moved or are duplicated elsewhere. * the second repaired disk for Daneel died after less than a minute of stress when rebuilding the RAID; happily the spare disk was here to take it over again until a new disk exchange is done... Hope this disease affecting disks will soon be eradicated... === Ruby for All === Recently, we removed the badly working mod_ruby apache extension, stopped using fcgid which was working but not so efficient/responsive, and switched to mod_passenger, which seems to behave quite well. You should be able to activate Ruby apps you need quite easily now, in your vhost, or in your personnal area (not limited to a single app). You can read more on this subject here: http://www.modrails.com/ and do not hesitate asking us if you need to override the ruby-app detection in your vhost, or need specific settings. _o< -- Marc Dequènes (Duck)

Coin, === Server Maintenance === On 2010-05-20 afternoon, due to sponsor needs, Orfeo had to move a few steps away in the same datacenter, and was halted twice during a few minutes. I was not able to warn soon enough to be useful, sorry for the inconvenience. On 2010-05-29 in the morning, while visiting a datacenter with several users, we will halt Toushirou a few minutes in order to replace/improve its memory (both because it needs more, and to test if a complete memory replacement would improve the stability, even if memtest found no problem on the current memory). === Communication === On 2010-05-19 Bitlbee was finally stopped. Minbif has replaced it nicely. In April, we experienced a lot of problems with our XMPP (Jabber) server. A few weeks ago we installed a fixed version and it proved very stable since then. The IRC upgrade is still... postponed :-/. === PHP Migration === Yesterday, we moved to 5.3, as planned earlier, and things went quite well. Please note a few things that are now obsolete and will be deactivated on 2010-09-01: - $HTTP_*_VARS - $argc / $argv - "magic quotes" So please check your code before the deadline. === Dico === Absolutely needed, we now have an open access dictionnary[1], available both on the DICT port, and via web on: http://dico.duckcorp.org/ dict/dico text clients are available on Thorfinn and Toushirou. Happy Birthday DuckCorp ! :-)) [1] http://en.wikipedia.org/wiki/DICT -- Marc Dequènes (Duck)

In May, Do what you Wanna Do !

Coin, === New Website === It has been a great while since we last took care of the official web page. No CMS was really that nice, so we decided to revamp it completely by hand (or mostly). It is still an "institutional" site, meant to stay quite static, but more opened to the human world. The old and obsolete content was removed/updated, so it reflects better what DuckCorp really is like today. === Changes in the Admin Team === Arnau was quite busy for a while, and not very active, so he is now a "fallback admin". Once again, happy volunteers are welcome ! === Jabber/XMPP Problems === Our server had strange problems recently, and was completely broken between 2010-04-27 and 2010-04-29. It seems to be "willing" to serve us again, so please pray the XMPP god it stays that way. === NTP === We have been running a stratum 3/4 server since a while, but it was not very advertised. Since 2010-04-22, it has been upgraded to stratum 2, advertised publicly on the ntp.org site, and registered in the pool project[1] (public stats[2] available). === LDAP Auth === The PostgreSQL server is now LDAP-ified, so users can now use their global identifiers. === Daneel's Disks Saga === One of the repared disk died on 2010-04-10, so we keep rotating disks until Seagate's warranty proves to be useful... === Mail === Since 2010-03-24, the maximum message size switched to 10Mo (was previously 5Mo), as requested by a few users. Do not forget we've got a FTP area for sending BIG files. === WebDesk === Since a recent Horde upgrade, tasks have been unusuable due to an uncompleted database migration. It has been fixed. That's all folks ! [1] http://www.pool.ntp.org/ [2] http://www.pool.ntp.org/user/DuckCorp -- Marc Dequènes (Duck)

DuckCorp, 10 years old already !
by DuckCorp Admin Team 26 Apr '10

26 Apr '10

Coin, You are a DuckCorp user, sponsor, or friend, so we wanted to invite you to the 10th anniversary of DuckCorp. It's the first time a such a "social" event is organized, but this time we wanted to meet you and have a look back at what we've done so far. The meeting will take place on 2010-05-29 near Paris (so you can book this date for sure). We do not want a corporate party, but something unaffected and relaxing, so we decided to organize a picnic. As the weather seems to get better and better each day, it should be enjoyable :-), but we can still fall back on indoors eating if necessary. The exact location and time would be communicated later, but it should start around 13:00. I've been told it would be interesting for people to visit a datacenter (most "normal" people don't live in there and have never seen how the Internet works), so it should be possible to visit Toushirou in the morning before the picnic, for a small amount of persons (but we may still organize another visit later if too much people are interested). In the evening, it is highly probable some of us end-up in a bar and/or restaurant for an unofficial continuation, so you are welcome to follow us :-). By the way, we started a new wiki dedicated to user-oriented information here: https://users.duckcorp.org/ You'll see a map of the network and some kind of historical résumé from the creation. It is currently readable by everyone (but this may change in the future), and users may login and contribute with their LDAP account (only a few pages are locked, but can be discussed). Please tell us if you expect to attend this meeting. It is necessary to "register" for the datacenter tour at least a week in advance to organize the visit(s). May the CoinForce be with you ! P.S.: You may reply to 10th-anniversary(a)duckcorp.org for general-interest discussions, but please use the Dc-Admin mailing-list to notify your coming or ask specific questions, so as not to spam people. -- Marc Dequènes (Duck)

Jacked up and good to go.

Coin, === Backup and Toushirou's recovery === Daneel's second disk died too (around 2010-02-06), but it was replaced quickly and is working nicely now. As a reminder, Daneel is performing our backup. Toushirou was severely hot by a nasty kernel bug[1], but is back to his "nominal" stability factor now. === Mail === Spammers worked hard, even during X-mas, and are online again brand new methods to circonvents our filters, so it is time for counter-attack :-). First, our antispam software (DSPAM) was upgraded again (2010-02-09), with a few fixes, both to the learning code and for optimizations. You'll see the web interface now support translations and French is now available (ask if you need another language). Second, we added new sources for our anti-virus software (2010-03-11), to now also be able to catch classic Phishing/fakes/... mails without the need for any DSPAM learning. Third, we are now using a new software (2010-03-13, policyd-weight) aimed at doing extra checks (some using RBLs) at the early stage of receiving mails, to be able to reject them as soon as possible. We hope this would help keep the learning burden for you as low as possible.. === IRC <-> IM gateway === Our new Gateway software has been upgraded and now support authenticating users using our global database (PAM+LDAP), so don't have to remember yet another password. To protect your password, TLS support has also been activated: you must then connect using implicit TLS/SSL, on the same 6670 port (unsecured connections are no more possible, and STARTTLS is not yet implemented in minbif as well as most IRC client softwares yet). Ask for an account if you want to try. === PHP 5.3 Migration === PHP was frozen on our hosts, as more recent 5.2.x versions were crashing like hell quite often. Seems like the 5.3 branch is stabilized a bit, and all oud hosts have migrated but Toushirou (the hosting web server). One extension, php5-imagick, is still non-functional, but we plan to switch to this new version at the end of the month. Beware it introduces a few incompatibilities, so please read the migration guide[2] if you are maintaining a PHP software on Toushirou (packaged software will of course be handled by the Admin Team). If you need a delay before upgrade, get in touch with the Team. === New pseudo-Machine === Thanks to the Nerim Root offer, we now have a new pseudo-machine available, Thorfinn (thorfinn.duckcorp.org). As was quite unpleased to see it was run by VMware, and ensured to cleanup the whole image before using it first. I heard it is planned by Nerim internally to replace VMware by something respectable (like XEN or KVM), but we have no schedule yet. So, please welcome Thorfinn among us :-). As Toushirou has to be rebooted once in a while, and even if it is not so horrible these days (beside the recent kernel bug), we are considering buying a new machine during this year. Before that, people having long term SSH sessions may now switch it to Thorfinn, which is expected to be more stable, and with a not so frequent need for major upgrades; this could save you a lot of effort. Thus, people having SSH access to Toushirou have automatically been grant ed an SSH access to Thorfinn. Feel free to ask for necessary softwares. === SSH Keys === As you may have seen, most SSH Keys are now in our magical database (LDAP), and managed automatically on all hosts where you have access to. Managed keys are marked between comments in your 'authorized_keys' file. They were initially seeded to ease transition, but it won't be automatic since now. You can ask an administrator to add/remove/replace keys as you see fit. You may add per-host keys manually if you wish, and they will be preserved locally. have a lot of FUN !

Need something destroyed?
by DuckCorp Admin Team 07 Jan '10

07 Jan '10

Coinyear ! :-) Hope this one would be awesome ;-). === Webstats === Authentication for webstats was <del>broken</del> a bit sick (due to the cold weather probably), and you'll be happy to ear it is cured now. === SIEVE Migration === In the past the SIEVE protocol (for the MANAGESIEVE service) used the TCP port 2000. This port was already used by another common application, and SIEVE has been assigned an official port: 4190. We plan to switch our service to this new port in the begining of february; until then, and starting from now, both ports are available, to ease the transition. === MySQL Migration === We switched from 5.0 to 5.1 yesterday night, and everything went like a charm. We didn't test every app/webapp using MySQL, but many were tested and seemed to work very well. If you need to adapt your SQL code, remember the doc is here: http://dev.mysql.com/doc/refman/5.1/en/upgrading-from-previous-series.html === Horde === Horde has been added a new module providing comics. The list of available strips is the default one provided by the module, but you can ask for addition or removal. It would be nice if you could report which one you like, so as to reduce the list to an acceptable size (and corresponding ressources on the server). === Backup failure === When i was away, a software problem (still undetermined yet) caused the backup to stop functionning at the end of december. Later, while we were all busy eating and drinking good stuff, a disk just died. Hopefully, thanks to RAID, nothing was lost, and the disk was replaced this evening. The service has been restarted and things you come back to normal soon. === Bitlbee is DEAD === Bitlbee software is mostly unmaintained. When Yahoo! or another naughty provider changes its protocol, it is quite a pain to get a fix (and sometimes you've got to wait weeks without been able to connect). It is not acceptable. Someone wrote a replacement, minbif (http://symlink.me/wiki/minbif), which is more IRC-ish, with funny new features, and using the pidgin library; the later is quite ugly, but probably not more than the Bitlbee counterpart, and would ensure up-to-date plugins for your favourite IM networks (with more choice btw). So, we decided to drop Bitlbee support and switch to minbif completely in the begining of february. If you want to switch to minbif, or discover it, please ask an admin for an account. === Tōshirō's Reboot === Here it comes. Toushirou started again misbehaving, after 224 days working nicely, so it will be rebooted tomorrow (2010-01-07) during the afternoon. A full disk check is needed, so please be patient. SSH users, don't forget to close your session before reboot; it will be advertised on IRC a few minutes before. Hope the rest of the year would be more calm... -- Marc Dequènes (Duck)

Reportin’ for duty
by DuckCorp Admin Team 17 Dec '09

17 Dec '09

Coin, === Secured FTP === One user reported a connection problem with the secured server, resulting in the following error: 534 Unwilling to accept security parameters This was due to a weird configuration problem on our server (probably a software bug). It is now fixed. === Postponed work === Due to overloading, the following tasks are postponed: - MySQL migration (5.0->5.1) was planned in november but will likely happen during the christmas holidays or at the end of january, so be prepared - Toushirou's reboot will perhaps happen during chrismas hollidays, but as it is not easy to plan, i'd rather contact people on IRC a few hours before - IRC migration should happen soon, as the test server is working nicely; you'll be warned... on IRC === Begging Time === Ho, this is already the end of the year. Not a so bad year, but we are still missing a few things : - workforce, to maintain DC/MP and help improve services and tools - funds, to pay the bill for these services - and a trusted and controlled KVM hosting, or perhaps a new machine, so as to restore the Earendil Hurd machine (used by HurdFr) and be able to debug it easily If you think you can help in one of these areas, just contact us. This said, have a merry X-mas everybody ! :-)) -- Marc Dequènes (Duck)
