This is probably masquerading related. Unless you can replicate it on a clean connection, it is not a problem with openssh appears to be a masquerade problem. please reopen if otherwise. Mass change of RESOLVED bugs to CLOSED |
Background: sshd openssh-2.9.9p2,openssh-3.0.2 only SSH2 (former ssh SSH1) ssh openssh-2.9.9p2 (former openssh-2.2??) server [C0] OS Linux 2.4.10-4GB-SMP firewall [C1] OS Linux 2.2.16 with ipchains masquerading [C2] client [C2] OS Linux 2.2.16 behind [C1] tcp/ip via pppoe on aDSL Since general upgrades to openssh-2.9.9p2 (same with sshd/openssh-3.0.2) the SSH2 (RSA-auth) connection from [C2] client behind the firewall [C1] to server [C0] freezes suddenly. This occurs repeatable when return packets get large (e.g. "ls -l" in big dirs, or "cvs update"). Before the connection was set up properly and worked for small packets. At the same time ssh-connections between [C1] and [C0] are not affected (both directions). Packet-logging on ppp did not show anything. Opening-up the firewall rules did not help. Any help is greatly appreciated Thanks in advance
