Unfortunately, ssh on linux regularly assigns ports when ssh'ing out from a box below 1024, I think this is a bug, but make writing firewall commands annoying.

Its not a bug, its a leftover from rsh days - if the connection originates from a port below 1024, you could assume *cough* that the credentials the connection supplies are authentic, since the process needs to be root to bind to ports < 1024. This isn't a "but thats flawed!" discussion seed, take that to bugtraq. There's a flag to ssh somewhere to stop it doing that. Yup, -P . Adrian
