[rancid] Re: Using Rancid to pus DST changes

[Lance]

I would think it would be much easier than that. Use clogin and do it
like so.

for i in `cat /usr/local/rancid/var/BWI/router.db | egrep "cisco:up$" |
sed 's/:.*$//g'`
do
clogin -t 90 -c "conf t;clock summer-time CST recurring 2 Sun Mar 2:00 1
Sun Nov 2:00;exit;wr mem;exit" $i
done

I wouldn't use end if you have a big mix of IOS versions. Some will not
support the word end to return to the cli.

Just change out
egrep "up$"
with
egrep "cat5:up$"
to get the catos devices. Make sure to change the clogin statemetn to
match as well.
