This is likely quite true Michael, but it also is only a hint as to how to fix it for the OP. I maintain 8 to 12 such ssh connections here to my othermachines, establishing them at boot time, but all are local 192.168.xx.xx addresses so not NAT'd going either direction, so I am not affected. I would be upset if I was. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
