Me too :)
I've successfully changed vty/console/enable passwords on large numbers of 
access-servers, routers, and switches in record time using expect.

I ran into an odd problem with expect recently though.  I know...I really 
should just take a look at Rancid (maybe next week)...but I was trying to 
come up with an expect script to archive configs last week.  I have the 
above mentioned book and know just enough expect to get basic things (like 
mass password changes) done.  I tried saving the config by sending show 
run and expecting "end\r\n\r\n".  Then I open a file and puts $output 
$expect_out(buffer).  This works on small configs, but on large routers 
with large configs, I'd only get some seemingly random portion of the end 
of the config.  I could run the script against the same router several 
times and get various sizes between 5 and 8kb in the output file.  There 
was apparently no pattern on consistency to it.  Has anyone else had this 
problem with $expect_out(buffer)?
