scripting telnet sessions, redirect issue


Code:
#!/bin/sh

while read ciscorouter
do
(
echo cisco
echo sho ver
sleep 1 
echo exit
)|telnet $ciscorouter > /var/tmp/version.$$
ver=`grep IOS /var/tmp/version.$$ | cut -d, -f2`
echo $ciscorouter $ver >> reportname
done < routerlist
should be self explanatory, goes through a list of cisco routers ( we have a couple hundred here ). for each router it telnets to it and does a sho ver then cuts that to just the IOS version and dumps the router name and version as side by side columns to a file.

my problem is I don't want any output to the terminal while this script is run. but when it runs I get a "connection to $ciscorouter closed by foreign host" dumped to the terminal for ever router it logs into. please help get rid of this extra output for me. thanks in advance

You could redirect standard error ?
I think this is how you would do it ...
Code:
telnet $ciscorouter > /var/tmp/version.$$ 2> /dev/null

GAH, now I feel stupid. the actual script has a nested loop that goes and creates a list of the routers. I tried that redirect before but I put it on the wrong loop like a idiot. it is in working order now, thanks you.

A second possible solution would be to use snmp. I've written little ksh wrappers to scan through a list of boxes and scan them (snmpwalk) for the information I needed.

I've had snmp recommended to me before but it doesn't seem to be on our solaris 9 boxes. if its not part of the default solaris 9 install its very unlikely that we have it and even more unlikely that I'll be able to convince my boss to install it.
