But now WASEL Pro introduces a new technology OpenVPN over SSH. This then limits the transfer speed and makes the scp complete successfully with no stalls scp now copies with 40-50Kb/sec, while before it was stalling after hitting above 100Kb/sec. We all know that WASEL Pro uses OpenVPN protocol. Verb 9 causes the openvpn server to log lots of data, and use up 100% of the CPU it is running on. When I set the verbose level to 9 on the openvpn server (not on the client, server only), the issue never occurs again. Posting it here, in case some people come up with any other ideas/hints. UPDATE 1: I found is a workaround to fix this, but it is a very ugly one. What makes this even more weird, is that if I do the same ssh-cat from Ubuntu, using the CentOS server vpn for internet to the public ip address of the centos-client (thus bypassing the centos-clientcentos-server vpn leg), everything works fine (no stalls, ever). I also tried all the MTU adjustment suggestions found in other threads (tun-mtu 1300 / fragment 1100 / mssfix etc) and none of them helps.

My setup is exactly the same as in the original qustion: CentOS server (topology subnet), and two clients, one CentOS and one Ubuntu14.03.

OpenVPN is an open-source commercial software that implements virtual private network (VPN) techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. The OpenVPN profile expects the SSH tunnel as a SOCKS proxy on local port 10000, so start SSH as follows: ssh -N -D 127.0.0.1:10000 -oUserKnownHostsFileperfectprivacyknownhosts -p 53 USERNAMEIPADDRESS.
