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.

OpenVZ server:
Kernel: Linux mrblack 2.6.32-5-openvz-amd64
Other stuff:
.- linux-image-2.6.32-5-openvz-amd64
