I would guess that something on the server (maybe a firewall) is causing either accept() or read() on high numbered ports to fail with EPERM. I'd suggest you strace/truss/ktrace the sshd immediately before triggering the failure and look for what's EPERMing. -- Darren Tucker (dtucker at zip.com.au) GPG key 11EAA6FA / A86E 3E07 5B19 5880 E860 37F4 9357 ECEF 11EA A6FA (new) Good judgement comes with experience.
