Hello,

Expect can be usefull if i have to do lot = interactive jobs,
All i need to do is log onto console(through = conservers console command)
invoke a command
and get its output back, Can this be done by = conserver ?
None of the commands I want to invoked are = interactive.

Also, another question, how do we configure = conserver.cf file so it wont
ask for a passwd ?

I tried

user::<hostname>
user:x:<hostname>

the above didnt help

The rule is users coming from 'trusted' hosts don't need a passwd, users from 'allowed' hosts do, and users from 'rejected' hosts are denied access in any event. I think all hosts are denied by default, unless specified as trusted or allowed. Does that help?

Howdy,

I am using conserver in this way:

Server is an Ultra5 running Solaris 2.6

conserver is latest rev, well last 6.blah rev

I have an Annex Terminal server which servers a = telnet port for each of it's 64 serial connections. It actually = listens on port 23 of a different IP per port, kinda wasteful, = but...

Connecting to the telnet port will give you serial = console on the machine plugged into the corresponding serial port on = the Annex.

Ok.

conserver's built in 'network connection' setting = wouldn't work, not sure why, but no problem, instead I used to the | = option to execute an arbitray command, in this case telnet, so my = conserver.cf lines look like this:

conanx2-port61:| /usr/bin/telnet = conanx2-port61::conanx2-port61.log:

Works great.

Well now I need to open 832 of these...

For each connection I get a message like this:
conserver: 16072 is the pid on /dev/ttyp0

So each connection is getting it's own tty, well = that's ok but I only have so many tty's, these are full fledged tty's = too, not pty's so I can't increase the number!!

My processes start competing for tty's and the server = never gets going just bounces around restarting the children all = day...

Why is this happening??

Why does it not open a pty for each of these??

Anybody else using conserver on solaris for a large = console farm like this??

Any response would be greatly appreciated.

Thanks,

When the device to which a console is connected is powered off, the cisco allows a single connection and then disconnect, but then leaves the line "logged in" despite the TCP disconnect and so future connections are refused. e.g. conserver>sh line Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int ... 38 TTY 9600/9600 - - - - - 0 0 0/0 - fenestro% telnet 135.197.18.3 2038 Trying 135.197.18.3...

That's good, but the network port stuff should work just as well...actually, better 'cause it won't chew up the pseudo-ttys (telnet usually requires a psuedo-tty for it to even function). If you use: conanx2-port61:!conanx2-port61:23:&.log: conanx2-port62:!conanx2-port62:23:&.log: etc, does it not work? I'm assuming I got the naming convention right...but that should open port 23 connections to each of those hostnames with logfiles of the form conanx2-port61.log, conanx2-port62.log, etc. I'm going to ignore the whole pseudo-tty problem 'cause getting it to open it's own TCP connections directly to port 23 will be a whole lot better in the long run for you. Trust me...less processes, psuedo-ttys, memory, etc. Plus the '!' syntax code is used by myself instead of the '|' syntax...so I know it works (but the '|' syntax works as well...just not quite as well on all platforms). Anyway, if you can let me know what happens with lines like above, I'd love to hear about it. It really should "just work".

As you've seen, it's not easy. What's really a bummer is that there's a statically allocated array that holds all the really interesting stuff. So, each child will have to re-read the configuration file or there needs to be some way for them to receive "updates" of sorts or told to not manage certain consoles or whatever. See, the real question is, if someone adds a console to a .cf file somewhere in the middle, everything gets shifted. The processes, if spawned newly, would each manage a new console and lose one as well (each get a set in the order of the .cf file). Those connected to consoles have TCP connections with particular child processes. Do you drop all connections and have things re-read and have the children know what group they're supposed to manage or do you feed a message to the children saying "don't manage this any more" and "manage this now" or do you spawn a new child for the newly added consoles and let the new child control all the new consoles. It's kind of a horrid problem. If you really want to attempt it (and I think it would be wonderful), I'd love to know what ideas you have (and maybe the list in general) so that we can all punch holes in any ideas...it's something that I think requires a whole lot of thought, because of the underlying architecture. One thought is that underlying architecture needs to just change, so that this is easier. I wish I had some basic ideas on how to improve things, but I haven't had a chance to think about anything but the pitfalls...hence my paragraph above. Anyway, good luck, and please keep at least me informed...it's a challenge I'd love to see conquered (and helping with the idea/planning phase is something I'd love to do).

I don't have any great ideas as to how to avoid it either. All I have to (potentially) offer is a script that will rsh to the terminal server and clear the lines for you. It's something an acquaintance of mine wrote and I believe the logic is that it does a 'console -u', looks for downed consoles, does a 'clear line ' via rsh and then (maybe) sends a SIGUSR1 to 're-up' all downed consoles. It's something that could be run occasionally, I suppose. Or, if I can't get a copy of it, the logic is at least there for someone to write a quick shell script (I'd love to put it in the contrib directory in the distribution). So, not much help, but maybe a work-around. If anyone has good cisco knowledge on how to avoid the issue, that would be wonderful, but I have faith in my cisco experts and they came up with the above logic, so I kinda doubt there's much of a choice (unless, of course, the most recent IOS provides something).

That's what I've been doing for a few years now...it's such a nasty problem to fix "right" that it seems to never go anywhere.

Modify the /etc/default/kbd file, by removing the # from the entry: #KEYBOARD_ABORT=enable and changing it to: KEYBOARD_ABORT=alternate that actually sets the alternate break, just removing the comment will set it to the standard break and setting (from memory) KEYBOARD_ABORT=disable will disable it completely, you can also use the kbd command to alter it. NB one thing we were wondering about this is at what level does the standard break operate, does anyone know if it's handled by something in the solaris kernel or by something in firmware as we have a minor concern that we might be losing some functionality by running with this patch. > _______________________________________________ > users mailing list > users@conserver.com > https://www.conserver.com/mailman/listinfo/users -- Iain Rae Tel:01316505202 Computing Officer JCMB:2148 Division of Informatics The University of Edinburgh From ChrisF@computone.com Mon Apr 30 07:27:32 2001 Received: from mustang.computone.com (mustang.computone.com [160.77.1.155]) by underdog.stansell.org (8.11.3/8.11.3) with ESMTP id f3UERWN01224 for ; Mon, 30 Apr 2001 07:27:32 -0700 (PDT) Received: by mustang.computone.com with Internet Mail Service (5.5.2650.21) id <2ZQ5M80F>; Mon, 30 Apr 2001 10:32:16 -0400 Message-ID: <95B97DD42B78D31193A8005004D1E05C413893@mustang.computone.com> From: Chris Fowler To: "'Ernie Oporto'" , users@conserver.com Subject: RE: Sun alternate break Date: Mon, 30 Apr 2001 10:32:12 -0400 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-Type: multipart/alternative; boundary="----_=_NextPart_001_01C0D182.5AB899D8" Sender: users-admin@conserver.com Errors-To: users-admin@conserver.com X-BeenThere: users@conserver.com X-Mailman-Version: 2.0.3 Precedence: bulk List-Help: List-Post: List-Subscribe: , List-Id: Conserver Users List-Unsubscribe: , List-Archive: This message is in MIME format.
