If by the same segment, you mean within the same 10.1.5.x domain, I can ssh if I use the IP number to the same segment (there are errors, but it ultimately succeeds), but I cannot ssh out of the segment, with or without IP number. Also, I can ssh into the broken box from within the segment. > > Ian > > ----- "Bill Tangren" <bjt@xxxxxxxxxxxxx> wrote: >> > On Dec 13, 2007 8:02 AM, Bill Tangren <bjt@xxxxxxxxxxxxx> wrote: >> > >> >> > >> >> > OK.
