Rsync 2.5.5; transfer via ssh; sparc-sun-solaris2.5 (Ultra 1); gcc 2.8.1. Every time rsync on this box causes boundary violation. I attached two strange examples. I have a few rsync's corefiles (100MB and above) and I can examine them. I will be grateful for any help. -Mirek <-------------------------------------------------------------------------> received 966761 names done

Hello, Noticed this (bug?) while testing out rsync. For a little background, I need to push files real-time to some front-end servers, and I am thinking of switching from some custom shell scripts that do this job to rsync. I am thinking of running rsync as a daemon on the front-end servers, and doing an upload from the back-end server to push the data out as it comes in. So, here is the deal:

People of cygwin & rsync, I recently attempted to get cygwin and rsync working to solve a backup/mirroring need in my computer life. Well, as you might guess, I ran into a little but of trouble. Strangely enough, rsync seemed to be regularly hanging when I attempted to do a "get" (sycronize a remote to a local dir). Well, considering I want to automate this, that was not going
