I identified and reported a problem with scp some time back. I have been moving files between FC4 boxes for a long time without problems. I updated some servers to CentOS 5 but my scp would die sometimes and about 1/2 time when it died, it created a core. After some testing, I found this same problem on Fedora Core 6 and on RHEL 5. I have yet to test F7. The CentOS bug is: http://bugs.centos.org/view.php?id=2241 My tests were in a tight loop, sending a 1024 byte file. It failed about an average of every 800-900 file transfers, so it is infreuent. I have tested it on Dell hardware and on Supermicro servers. Cheers, -- Wade Hampton
