I am using SSH on a SUN Ultra 2 with a Solaris 5.6 operating system. The machine also runs the following servers:
ORBIX 2.2
Oracle 8
NIS (yellow pages)
The machine is also managing an external RAID disk and sharing its file system with an ATM switch.
I am running the command with the following options:
ssh -f -l <user> -enone -L <localport>:<localhost>:<remoteport> <remotehost>
Everything seems Ok but when I issue the ftp localhost from another
shell, the system hangs.
After some attempts I have found out that the -f option is the
one the blocks the system. Looking at the ssh man pages I found that -f
also implies -S and -n. performing another test I found that -n
is probably creating the problem. In fact the -n option hangs the system
even before issuing the ftp localhost command.
I am trying the same from another machine (same model and same operating system) and I don't get the same problem. So I wonder if this may be caused by the particular configuration of the operating system, a conflict on a port, the presence of some daemons, etc.
Did anybody have the same problem ?
Thanks a lot in advance
Nino
