Hello Toasters,
What's the easiest way to fix these ssh related errors reported by the filers?
[sshd_0:info]: Postponed publickey for <user> from <client> port 47309ssh2
and also these related ones:
[ems.engine.inputSuppress:warning]: Event 'openssh.invalid.channel.req' suppressed xxx times since [openssh.invalid.channel.req:warning]: SSH client (SSH-2.0-OpenSSH_4.3) from <client> sent unsupported channel request (10, env).
NOW wasn't much help here.
thanks in advance

No idea, never saw that error before. We exclusively use public keys to login on the filers, aren't you?

Ah, your ssh client is trying to send environment variables (see SendEnv in man ssh_config(5)). The filer doesn't know how to handle that. The ssh default is not to send environment vars, but some distributions supply a system-wide /etc/ssh/ssh_config that includes, eg, "SendEnv LANG LC_*" (Debian, ubuntu).
The solution is to override that. There is no 'NoSendEnv' in ssh, but it's easy not to send an environment variable by supplying a non-existing env var. So, put this in your ~/.ssh/config:
Host MyToaster SendEnv THISENVVARDOESNTEXIST
HTH,
Thanks to all who replied. The host causing this issue is a Solaris 10 box. The ssh_config is all commented out. Adding the SendEnv line causes an error
