Problems with 8.1.0

Post #1 of 4 (608 views)

I am trying to configure conserver 8.1.0 using ssh and am having problems
connecting using the console command.

The logfile reports the following:

login: [-- root@lds001 attached -- Fri Feb 27 10:06:44 2004]
[-- root@lds001 detached -- Fri Feb 27 10:06:53 2004]
[-- Console down -- Fri Feb 27 10:06:53 2004]
[-- Console up -- Fri Feb 27 10:06:53 2004]
SSH-1.99-OpenSSH_2.9p1
[-- root@lds001 attached -- Fri Feb 27 10:07:15 2004]
[-- root@lds001 detached -- Fri Feb 27 10:07:20 2004]
[-- Console down -- Fri Feb 27 10:07:20 2004]
[-- Console up -- Fri Feb 27 10:07:21 2004]
SSH-1.99-OpenSSH_2.9p1

and the screen which I am running the console command on comes back with:

[Enter `^Ec?' for help]
SSH-1.99-OpenSSH_2.9p1
[read-only -- use ^E c ? for help]
[read-only -- use ^E c ? for help]
[read-only -- use ^E c ? for help]

I presume that I have a config error in my .cf file, but not sure what to
start looking at.

And ideas would be most appreciated!

I'm new to conserver, so I'm sure someone may have a better answer, but it
looks like the session is only read-only. Did you try ^E c a to get a
read write session?

and if that doesn't let you in, your account might be in the 'ro'
(read-only) list in the conserver.cf file...and changing it to the 'rw'
list would give you read-write access.

it's weird you're seeing the 'SSH-1.99-OpenSSH_2.9p1' messages...but,
since there's a 'login:', should be working.

How about some setting that will only start so many connections per unit of
time per server? I've set my exec command to something like...

exec "sleep 10; /usr/local/bin/ssh -p 2210 ..."

for port 10. I'm only doing one connection per second that way. It's
really stabilized the startup of conserver. We have 48 port InReach
terminal servers and it cannot initialize 48 ssh connections in short order
without hanging.

nope...and i doubt there ever will be, since keeping up with the
protocol and not introducing security bugs, etc, would probably kill me.
i, at least, expect ssh to "just work" and i rely on openssh and that
community to keep it all honest.

i really wish there was a way to prevent all those processes, though.
if you have a couple 32 port terminal servers, you can really get a lot
of ssh processes going (and it can be hell for the terminal servers to
keep up with all it's ports doing encryption/decryption...it used to
strike fear in the vendor's hearts when you ask "can it support 32
simultaneous ssh connections?"..."how long?"..."indefinitely."..."no,
i'm serious...you see, i have this program...").

but, if you have any good ideas on how to reduce the overhead of things
or a better way to integrate ssh, i'd love to hear 'em!
