Hi!
I've problems copying files from an old OpenSuSE to an OpenVZ container running Debian GNU/Linux 6.0 i386 template.
Error:
dns:~/tmp # scp file.sql.gz root@192.168.1.4:/tmp
file.sql.gz 23% 8576KB 140.8KB/s - stalled -Connection to 192.168.1.4 closed by remote host.
In both servers I've changed server alive interval params in sshd configuration but scp comamnd fail.
