Packet integrity error. (34)
Hi, I am using Van Dyke SecureCRT 3.2.1 to access an AIX server running OpenSSH-2.5.0p1. Using ssh1 with X11 forwarding enabled, the server reports the following error (in the client session): Packet integrity error. (34) This problem was not evident in 2.3.0p1. Running sshd in debug gives the output: debug1: sshd version OpenSSH_2.5.1p1 debug1: load_private_key_autodetect: type 0 RSA1
