RE: Password changes on cisco routers

[Sean Davidson <sean.davidson@mail.publix.com>]

You can also use just plain shell scripts. Here's an AIX shell script I use
to tftp config, write it to memory, and then write it to a tftp server. It
uses SNMP, so you must have snmpset executable on machine you are running it
from, the necessary Cisco MIBs loaded, and the snmp write community string.
The input file should contain IP addresses or resolvable names. The name is
usually the better approach because it will use this name/ip address with
"-confg" appended to it when writing back to tftp server. You can put
multiple names in the input file.

#!/bin/sh
# usage: rsdcw.sh < file.containing.list.of.routers
#
# NOTES:
#
#     -  The last octet of the cfgNet variable must contain the IP address
of
#        the TFTP server.
#
#     -  The last octet of the writeNet variable must contain the IP address
of
#        the TFTP server.
#
#     -  The errlog variable indicates the path/filename exceptions will be
#        written to.
#
#     -  The config variable must contain either a valid path/filename or a
#        validated in the default TFTP read directory (/tftpboot). The file
must be
#        a valid Cisco configuration file. (containing valid Cisco commands)
#
#     -  The timeout/retries variables are for the snmpset commands.
#
#     -  This script defaults to using the snmp community strings specified
in
#        /usr/OV/conf/ovsnmp.conf. Make sure these strings are correct.

Hi all, 
this isnt really a Netview question but thought some one might be able to
help.
I need to be able to change passwords from a script, I used to have a telnet
scripting tool but it doesnt run on unix.
Does anyone know where i can get one, have not been able to find one on the
web.

Thanks Arthur
