Postfix dying
by Paul Norton 13 Nov '07

13 Nov '07

Hello list, Postfix is dying on one of my servers almost nightly. This system is running CentOS5 with postfix-2.3.3-2. In the morning (after noticing it died) I try to run `service postfix stop` and I get a failed start. Running `ps ax | grep postfix` I can see one process still running for postfix. After killing this, I am able to run `service postfix start`. I see a lot of this in my maillog: Nov 7 00:25:13 servername postfix/smtpd[16727]: lost connection after CONNECT from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16715]: disconnect from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16727]: disconnect from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16723]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:25:13 servername postfix/smtpd[16723]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:25:13 servername postfix/smtpd[16723]: lost connection after CONNECT from unknown[201.251.x.x] Nov 7 00:25:13 servername postfix/smtpd[16723]: disconnect from unknown[201.251.x.x] Nov 7 00:27:22 servername postfix/smtpd[16184]: warning: timeout on private/anvil while reading input attribute name Nov 7 00:27:22 servername postfix/smtpd[16184]: warning: problem talking to server private/anvil: Connection timed out Nov 7 00:27:22 servername postfix/smtpd[16910]: warning: timeout on private/anvil while reading input attribute name Nov 7 00:27:22 servername postfix/smtpd[16910]: warning: problem talking to server private/anvil: Connection timed out Nov 7 00:27:22 servername postfix/smtpd[16726]: warning: timeout on private/anvil while reading input attribute name Nov 7 00:27:22 servername postfix/smtpd[16726]: warning: problem talking to server private/anvil: Connection timed out Nov 7 00:27:23 servername postfix/smtpd[16184]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16184]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16184]: lost connection after CONNECT from unknown[201.251.x.x] Nov 7 00:27:23 servername postfix/smtpd[16184]: disconnect from unknown[201.251.x.x] Nov 7 00:27:23 servername postfix/smtpd[16910]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16910]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16910]: lost connection after CONNECT from unknown[86.123.x.x] Nov 7 00:27:23 servername postfix/smtpd[16910]: disconnect from unknown[86.123.x.x] Nov 7 00:27:23 servername postfix/smtpd[16726]: warning: connect to private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16726]: warning: problem talking to server private/anvil: Resource temporarily unavailable Nov 7 00:27:23 servername postfix/smtpd[16726]: lost connection after CONNECT from cpe-024-x-x-x.carolina.x.x.com[24.74.x.x] Nov 7 00:27:23 servername postfix/smtpd[16726]: disconnect from cpe-024-074-x-x.carolina.x.x.com[24.74.x.x] TIA for any suggestions. -- Paul Norton Systems Administrator Neoverve - www.neoverve.com Neoverve Blog - http://blog.neoverve.com/

Re: [CentOS] backups and md5 all in one while splitting
by Ross S. W. Walker 12 Nov '07

Well in bash/sh the () means execute in a sub-shell. If you redirect or pipe output from one process to a command in a sub-shell it will be redirected or piped (whatever the original was) to the command being executed in the sub-shell. You can also use $(command) as a command-line variable that will substitute the output of the command during evaluation. Ie # mkinitrd /boot/initrd-$(uname -r).img $(uname -r) -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Mon Nov 12 17:57:11 2007 Subject: Re: [CentOS] backups and md5 all in one while splitting Ross S.

'tee' splits the stdin into multiple output streams. The first instance of tee you listed gave it a file name and a pipe to output the stdout to. The second instance did a redirection to a sub-shell which then passed it to 'split' and it also had a pipe. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Mon Nov 12 17:44:47 2007 Subject: Re: [CentOS] backups and md5 all in one while splitting Shad L.

How to know when files have finished FTPing?
by Neil Aggarwal 12 Nov '07

12 Nov '07

Hello: I have a server set up a CentOS 5 server for a client to push files onto using FTP. I have a cron job to process the files and move them to another directory. Sometimes, the cron job executes while the client is still uploading a file (Some of them can be large) and I get a partial file. Is there a way to tell when a file has finished uploading? I am using the vsftpd daemon installed using yum. Thanks, Neil -- Neil Aggarwal, (832)245-7314, www.JAMMConsulting.com Eliminate junk email and reclaim your inbox.

GStreamer Plugins for Apple QuickTime .mov files
by James B. Byrne 12 Nov '07

12 Nov '07

I have a requirement to view a .mov file on my CentOS workstation and Totem reports that it requires a plugin. Does anyone here know which plugin package from gstreamer.freedesktop.org contains the necessary codec? I seem to have a choice between gst-plugin-ugly and gst-plugin-bad, two highly inviting names. Or is there another package that I need? Thanks, -- *** E-Mail is NOT a SECURE channel *** James B.

Automatic User Based Mounts
by Scott Moseman 12 Nov '07

12 Nov '07

Let's say I have a Samba server for my file serving needs. Would there be any way to configure CentOS to automatically mount a few specified partitions as the user logging in? Something of the nature of /mnt/home, /mnt/pictures, /mnt/music and so forth. They need to be mounted as the current user, and I prefer not to customize shell based login scripts. Can this be done through fstab somehow? Or some other method? I can make, and currently utilize, SMB share links on my desktop for accessing them. However, when applications want to open or save directly to the file system, I'm unable to reach the network shares. In the grand scheme of things, this makes having network shares pretty much useless. There must be a better way? Thanks, Scott

Can not print with OpenOffice.Org on CentOS 5.0 x86
by Ioannis Vranos 12 Nov '07

12 Nov '07

I can not print any document with OpenOffice.Org Writer on CentOS 5.0 x86. Has anyone encountered this problem? My printer is HP Deskjet 3745 and apparently uses the hplip and hpijs packages provided by CentOS.

Re: [centos] how to know when files have finished ftping? -- antair restored

Here's a thought: what about doing an lsof? If a file is still being written by ftpd it should be open for writing.

You may be able to get the list of files to process using 'find'. If you check using "-mmin +X", you might be able to get only files that haven't been updated in X minutes. That should filter out anything in progress. If a transfer is stopped in the middle, then restarted later, that wouldn't help here. It's possible that the FTP daemon might not update this information, so you'll have to expieriment. It's worth a shot before you start telling the client to modify their process. _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos Sent from my BlackBerry wireless handheld.

CentOS 5 Boot Issues
by Robert Slade 12 Nov '07

12 Nov '07

Hi all, I am still having problems with my desktop system. Having updated it from 4 to 5, I now have problems with the logs. Neither boot.log nor dmesg has any data post the update. syslog appears to be normal in that it starts when it should but does not show any errors. It looks like whatever is supposed to write to the logs during initial boot is not doing so, but I am not sure where to look to see what is wrong. The other problem I have may or may not be related it is not notifying me when updates are available although Yum etc appear to be working correctly. I have all the data backed up and I could do a fresh install, but I am trying to avoid this as I would have to spend a lot of time reinstalling software etc. Any suggestions? Thanks Rob

HP DL585 - CentOS4.5 - kix woes
by Tom Brown 12 Nov '07

12 Nov '07

Hi Well we are now using HP instead of Dell and have hit a major hurdle. We dont seem to be able to kix any of these boxes. I have been most recently trying on a dl585 and the issue appears to be that the kix kernel does not detect any nic. Its strange as the box can be installed using iso's and the nic appears as eth0: Broadcom NetXtreme II BCM5706 1000Base-T (A2) PCI-X 64-bit 100MHz found at mem fa000000, IRQ 209, node addr 001a4bedcf1c bnx2: eth0: using MSI which seems a pretty standard nic to me - has anyone been able to kix new hp kit recently using 4.5 ?? thanks
