[SLUG] Rsync problem
A week or so ago I had problems with ssh not quitting when run in a cron script. This time I have a problem with rsync seemingly stalling. The difference this time is that is seems to stall irrespective of whether it runs under cron or standalone. Any clues as to where I should be looking -- Howard.

Re: [SLUG] Rsync problem
I recently had a similar problem (rsync stalling when ssh'd accross a network) which was solved by adding -vvv to the options. It seemed to be some sort of timing problem, which forcing verbose mode resolved. Since then i've removed the -vvv and it no longer stalls. This proves that administering linux is not an exact science, and that your problem may also be resolved with newt's eyes or frog's livers, or both in a mysterious combination. David.

The difference this time is that is seems to stall irrespective of whether it runs under cron or standalone. Is rsync not returning after its done the work, or similar? We had a similar issue at home over dialup, which was fixed by a reduced MTU. - Jeff -- Are you XFire's crazy girlfriend?

Check your MTU size Hack fixes (like above) are cool, but fixing the problem rather than masking the symptoms is even cooler :-) -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

No, it only proves you don't know what your problem was caused by. If you are curious or if the problem reoccurs delving into the sys and rsync logs will provide some clues. -=-=-==-=-=--=-=-=-=-=-=-=-=-=-=-=-= Graeme Robinson - Graenet consulting www.graenet.com - internet solutions -=-=-=-=-=-=-=-=-=-=-==---=-=--=-=-= -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

I've had similar problems with rsync over many different machines, over rsh, ssh, solaris, hpux, linux, with no apparent cause or resolution except by waving around a rubber chicken. Search through the rsync mailing list archives and you'll see many references to it, with the occasional fix with the comment 'yeah we've got it THIS time' I think it must be something fundamental to the rsync protocol which is broken.

RE: [SLUG] Rsync problem
The only problems I've had were with getting MacOS9 files off a MacOSX system transferred to a Linux system. I ended up doing it manually in the OS9 application and using ftp to transfer the stuff across. Other things to look for: - time/date synchronisation on both machines - files which are being opened and updated while the rsync is progressing. I suspect the file seeks on rsync might be relying on the opened file being fairly static. For short files, it should not be an issue, but for longer ones, strange things might happen if the file gets written by another process. Cheers, Jill. -- Jill Rowling, System Administrator Eng.

Reminds me of a problem at work where the card was set to full duplex and the network gear only accepted half. ftp was very messed up which surprised me. -- -- Thanks KenF OpenOffice.org developer -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
