It doesn't look like ssh is running at all. Maybe it didn't get installed properly?
ipkg status openssh-client
should return:
Package: openssh-client
Status: install ok installed
Root: /
Version: 3.6.1p1
If thepackage is installed properly,
ssh -V
should return
OpenSSH_3.6.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090702f
ssh without arguments should output about two pages worth of help.
