Firefox 3.5 Issues
by Ron Blizzard 17 Jul '09

17 Jul '09

I downloaded Firefox 3.5 from the M. Harris site and, for the most part, have had good luck with it. But I have also had hard crashes that take down CentOS, not just Firefox. It happened to me twice on eBay (on the same page) -- and now I can replicate it as many times as I want by going to... http://wiki.centos.org/Newsletter ...and choosing one of the two newsletters, linked there. I'm writing for a couple reasons. I'm curious to see if this is only my problem, or if other have experienced it or can replicate it. And I was also wondering how I can remove Firefox 3.5 and its associated support files and get back to the regular repository. Firefox 3.5, for the most part, is very stable and is snappier than 3.0.11 -- only two sites have pages have crashed for me, but when it crashes it takes down my whole system and that's not good. And, if someone could mention this on the forum (there is a thread about Firefox 3.5) I would appreciate it. I can't log on to the forums. I am supposed to ask for another password, but I can't remember what my original email address was (2 or 3 years ago). Thanks for any pointers. -- RonB -- Using CentOS 5.3

passing alias addresses
by Jerry Geis 17 Jul '09

17 Jul '09

hi all, When using the alias address scheme, like eth1:0 on a machine ... things are working. When that interface is disabled on box A and becomes active on box B what should Box B do to correctly update the ARP tables external to box B so the external world knows how to get to the new destination and not the old box A?

x86_64 EDAC throwing error
by Kurian Thayil 17 Jul '09

17 Jul '09

Hi All, We have installed CentOS 5.3 x86_64 in an HP DL585 server with AMD Opteron 64 bit processor and 16 GB RAM. The kernel version is 2.6.18-128.el5 . Now this has thrown an error message in /var/log/message, Jul 3 21:41:11 db1 kernel: EDAC k8 MC0: general bus error: participating processor(local node origin), time-out(no timeout) memory transaction type(generic read), mem or i/o(mem access), cache level(generic) Jul 3 21:41:11 db1 kernel: EDAC MC0: CE page 0x65bc7, offset 0x6a0, grain 8, syndrome 0x6e1a, row 0, channel 0, label "": k8_edac Jul 3 21:41:11 db1 kernel: EDAC k8 MC0: extended error code: ECC chipkill x4 error Jul 3 22:00:00 db1 ntpdate[3813]: step time server 120.88.46.10 offset -4.375417 sec Jul 3 22:12:57 db1 kernel: EDAC k8 MC0: general bus error: participating processor(local node origin), time-out(no timeout) memory transaction type(generic read), mem or i/o(mem access), cache level(generic) Jul 3 22:12:57 db1 kernel: EDAC MC0: CE page 0x65bc7, offset 0x6a0, grain 8, syndrome 0x6e1a, row 0, channel 0, label "": k8_edac Jul 3 22:12:57 db1 kernel: EDAC k8 MC0: extended error code: ECC chipkill x4 error I understand this is an error message from Error Detection And Control module and just wanna confirm that this is not a kernel or software related issue. If Hardware related is it confined only to the Physical memory stick installed or processor related? Any hint on this?? Regards, Kurian Thayil.

NIC traffic monitoring, recording and reporting software?
by James B. Byrne 16 Jul '09

16 Jul '09

I have a remote CentOS-5.3 installation that shares traffic with another enterprise. I want to record and measure the actual network traffic that comes into and goes out of that host's net i/f on a monthly basis for billing verification purposes. Does CentOS have a software package to accomplish this? I have run across references to a package called vnstat as a possible answer to my requirements, but I cannot seem to locate a CentOS rpm package for it.

nfs (v3?) fails to allow writes and permission changes
by Rob Kampen 16 Jul '09

16 Jul '09

Hi All, I have an nfs mount from my CentOS 5.3 client to a CentOS5.3 server. This has been functioning correctly for some years. Beginning last week I had problems saving OpenOffice documents onto the nfs mounted volume. OpenOffice just times out with a file io error. So I tried just a simple shell - cd to the mounted volume did a vi create of text file - no problems. tried a chmod +w on an owned file - returned okay but no change to the permissions when checked with ls -l tried sudo chmod +w on the same file and get [rkampen@robsws p_494]$ sudo chmod +w 5887_cover.pdf Password: chmod: changing permissions of `5887_cover.pdf': Operation not permitted yet using gnome file browser I can change permissions on these nfs mounted files just fine - go figure. This did work in the past - so what has changed? how do I check what version of nfs is actually working? [rkampen@robsws p_494]$ mount 192.168.230.230:/NDG on /NDG type nfs (rw,noatime,intr,addr=192.168.230.230) Any thoughts? Thanks Rob

Initial backup prior to daily rsync backups
by Jeff Gregor 16 Jul '09

16 Jul '09

I have a few CentOS 5.3 servers out at remote sites that connect over a satellite link (a painfully slow satellite link). There's a time period in the wee hours of the morning when the satellite provider doesn't stiff me for bandwidth, and when the link is generally idle, where I want to use rsync to back up files to my local server. I've got rsync working in in combination with cron and ssh, and that process works fine. The problem is getting the initial copy of the files over to the local server so that rsync can just deal with files changed during the day (there tend to not be too many changes -- mostly office-type documents, few pictures, that sort of thing, so limited bandwidth is not a problem). If I run rsync now, however, it is trying to copy over all the files since none exist on the local servers, and by my calculations copying that 160gb worth of data should be done some time in mid-February, 2010. I can make the 4-hour round trip out to the remote site with a USB hard drive and copy the files that way, but my concern is how to get the file structure, timestamps, permissions, etc copied exactly from the remote server > USB drive > local server so that rsync can run most efficiently (and not have to do a compare on every single file the first time it runs.) So the question is, how do I copy the files from the remote server back to my local server in a way that will allow rsync, once the copy is complete, to start dealing just with the daily changes in the most efficient way possible? Thanks!

OT: Web "Project" type software

I am building a fairly sizable dbms based project and I started out with subversion as the SCM and Trac as the PAS. Last year I switched the project to Git and Redmine respectively. Both are open source. Git is the Linux kernel maintainers' SCM system and was initially designed and written by LT himself to replace BitKeeper. It is a completely distributed SCM and is very easy to use, albeit not so easy to learn or understand. > Here's what I'm looking for: > 1) Web enabled application Redmine is 100% Ruby and Rails, totally web based. It supports Git repositories out of the box. Git is a combination of scripts and C programs. It is available for Linux, Microsoft and several other OS platforms. Repository structure is identical for all platforms although differs in implementation details. On MicroSoft environments I hold that Git is best hosted under a cygwin instance, although a native port does exist. > 2) File storage - need to stare a large amount of large cad files - be able to categorize file storage (not one large list) - keep different revisions of files with some kind of notes - be able to search files (at least include names in a search) Remine uses the underlying fs for file storage and provides the metadata for search. Files can be placed into a document list or attached to individual wiki pages. A description can be provided upon creation, although at present there seems no supported way of editing an existing description. Redmine supports full test searching. However, Git is by far and away the best solution to the problem of large file storage. Redmine can index a Git repository and track individual change sets. Therefore, Git + Redmine will give you most, if not all, of what you ask for. > 3) Task - assign and keep track of tasks (searchable) Redmine supports multiple projects and sub-projects in a single instance. Issues may be related to one another. Users may be assigned differing roles on different projects. Different projects can have different categories and statuses. The DBMS backend is PostgrSQl so any report writer with an SQL backend should be able to provide whatever reports that you have the data to drive. > 4) Store meeting notes and minutes (searchable) In addition to issue tracking and file storage, Redmine provides both project specific wikis and web forums. Access to either can be controlled on a project/user basis. The full text search facility covers both. It also has time logging and a slew of other features. > 5) Would like to support LDAP I believe that Redmine does, but I do not use this myself so I cannot be sure. Git is a filesystem, it has its own network transfer protocol which is very fast and completely insecure. It also supports transfer over http, very slow and insecure, and ssh, acceptable speed and secure transfer. > 6) Extension on file storage - since we'll be storing a large files > and many of our users are across a WAN we'd like to sync/mirror > the files to a few different servers. I'm not sure how we'd control > how the users get the "closest" server but.... If you use Git instead of Redmine for your large file store then each user gets a complete repository the first time that they pull (clone actually) from the remote, including all the source changes to initialisation. Thereafter they only get the diff objects. Git uses a very efficient storage mech. that basically only passes compressed diffs of file contents. It uses MD5 hashes of file contents to identify change sets so that if you rename a file or merge two into one it can track these events and avoid duplicate storage. I use a cron scheduled git pull over ssh to maintain a remote copy of our base repository and the traffic created is negligible even after large commits. If the Git repository containing those files is bound to your Redmine project then you can search the files therein through Redmine and compare diffs across multiple versions. Of course, nothing is going to help much with binary data files. HTH -- *** E-Mail is NOT a SECURE channel *** James B.

Re: [CentOS] My server reboots every hour! Help please! [update]

I asked a collegue of mine (who happens to have physical access to the machine) to shut it down and get into the BIOS to check for the "wake on lan" status. He did (it was off) and he left the machine hanging in BIOS for an hour waiting to see if it would restart. It didn't, for two hours. He was also monitoring temerature and voltage and comparing them with two other machines in the room (identical hardware) and nothing seemed out of ordinary. Then he rebooted to CentOS, and since then restarts have not happened for a whole day now: # uptime 16:26:25 up 22:11, 1 user, load average: 0.00, 0.00, 0.00 That means that (a) the problem went away and (b) I am not able to reproduce it. From the logs I read that the resets were happening every 3625 +- 10 seconds, so to speak. The idea of intentionally skewing the system clock and wait for a reaction was my next step, but since it stopped restarting I cannot verify anything now. Since the problem went away, I am moderately happy, so we can drop the thread, and I'll make sure to reopen it if I see it restarting again. Thanks to all for suggestions and help! Best, :-) Marko
