Thanks Casper, I wondered where the defaults were. But
no, that file has not been touched.

Yes, its particular set of terminals. I haven't checked
whether the number of strange ones is increasing though
it feels that way, but as I say I can't confirm that.

I haven't rebooted recently.

All of the devices in /dev/pts are owned and grouped root.
The software is an old Solaris binary of `rtn' a reverse
terminal server. I give it an alias, say /dev/myalias,
which it associates with a telnet connection to a given
ip address and tcp port. I create two such aliases:
/dev/myalias1 -> terminalserver1.somewhere.net:port1
/dev/myalias2 -> terminalserver1.somewhere.net:port2
It links myalias1 and myalias2 to next available /dev/pts.
Both network connections are made, but only one of them,
the first setup, is operative. Run in debug mode, it
complains as follows when the second pseudoterminal is
1081716708554381 ERROR: Unable to reuse master pty on multiplexed device.
The command that invokes the reverse telnet daemon is run as
root. /dev/myaliases are root.other, and the ultimate
targets /devices/pseduo/pts@0:nn are root.tty and look fine.
However, its only since using `rtn' - creating and tearing
down network connections and /dev links - that I've seen the
I need simultaneous access, via different pseudoterminal
aliases, to more than one port on a remote terminal server.
`rtn' is only giving me one, so I'm looking for a replacement
Anyone have a copy of csportd for Solaris?
Thanks for your suggestions Casper.
