Hi everyone,

Recently I faced a problem where rancid could not fetch the config of a 
new router in my network. The logfile reported the following:

couldn't compile regular expression pattern: parentheses () not balanced
     while executing
"expect -nobrace -re {pcsrouter\(02\([^#>\r\n]+)?[#>](\([^)\r\n]+\))?} 
{} -re {[
^M]+} { exp_continue }"
     invoked from within
"expect {
             -re $reprompt       {}
             -re "\[\n\r]+"      { exp_continue }
     (procedure "run_commands" line 23)
     invoked from within
"run_commands $prompt $command"
     ("foreach" body line 144)
     invoked from within
"foreach router [lrange $argv $i end] {
     set router [string tolower $router]
     send_user "$router\n"

     # Figure out prompt.
     # Since autoena..."
     (file "/opt/rancid/bin/clogin" line 617)^M

The problem was the hostname length, which was more than 14 characters 

My solution was to change line 511 of clogin, and put a bigger number 
instead of 14 (say, 24) ...and the problem was solved :-)
