I've got an intranet mirror of centos, been updating it periodically, recently my updates started failing... I've tried several different mirrors as sources, but each time, the update fails at some random point with this error...
rsync: read error: Connection timed out (145) rsync error: error in rsync protocol data stream (code 12) at io.c(614) [receiver=2.6.8] rsync: connection unexpectedly closed (1605001 bytes received so far) [generator] rsync error: error in rsync protocol data stream (code 12) at io.c(463) [generator=2.6.8]
per a bit of googling, it appears this may be a generic 2.6.8 error, as explained here... http://www.mail-archive.com/rsync@lists.samba.org/msg16205.html
for what its worth, my local mirror server is actually a Sun ultrasparc running Solaris 10, with its built in rsync 2.6.8, which appears to be the same version as is running on the centos mirror servers.
