search for: cron'ing

My setup is: I run rsync daemonized on various server machines in my LAN - i.e., the source machines certain partitions of which I want to backup. I would like the client, destination archiving machine to run hourly crons over SSH, but so far the only thing I have been able to do is rsync across (as root so that I am not denied anything) only after interactively supplying my root password to the SSH daemon. How do I get around interactive SSH interactive password requirement so that I can cron all these rsync clien...

...t by changing the local time source. There are something like 5 options. Google for "Linux time" or similar. Or, simply replace the hardware--RTC chip, mobo, etc. If any of these cluster members are virtual machines, regardless of hypervisor, I'd recommend disabling using ntpd, and cron'ing ntpdate to run once every 5 minutes, or once a a minute, whatever it takes to get the times to remain synced, against your local ntpd server mentioned above. I got to the point with VMWare ESX that I could make any Linux distro VM of 2.4 or 2.6 stay within one minute a month before needing...

for some strange reason, our wins servers occasionally drop samba servers out of there name space. to deal with this, I cron'ed a restart of samba at midnight everynight. This was a quick solution, but a lousy one. I would rather have some way to have samba regularly send name registration requests to wins. Is there a way to do this? barring that, is there some interface I can query on samba before sending it a kil...

As of late our four node dovecot 1.2.13 cluster has been experiencing a massive number of these dotlock errors: Created dotlock file's timestamp is different than current time (1295480202 vs 1295479784): /mail/user/Maildir/dovecot-uidlist These dotlock errors correspond with very high load averages, and eventually we have to turn off all but one server to stop them from occurring. We first

Ouch, part reset, quickly restoring reality (0) Power alarm on module 1, resetting! I have looked though a lot of email on this issue, and no one seems to have the answer. How many people are seeing this on a TDM400 card? Does anyone have a "REAL" answer to it. Yes, I do have the power connected to it! Regards Garry Taylor

I noticed that occasionally searching in my huge archive mailbox can be really slow, so I tried doveadm index on it and it seemed to do a lot of work, which seemed strange given, for example, that dovecot-lda says it keeps Dovecot index files up-to-date. Then I thought, "maybe these are different files than the search indices." If so, that's not entirely clear from the docs and

...ive some of the files via a CIFS mount, I've experienced permission problems with various files and folders. A local tar of the files has gotten around that, then just have the Windows box copy the tar files to tape. Now to see what options tar has for producing incremental backups with a cron'ed tar job, unless someone has a better, comparable approach with existing OS tools (tar, cpio, dump, etc). I want to retain as many permissions as possible. I've tried rsync before, but that also requires enough disk space for the file copying, and some of the options I've used h...
