Hy,

I got that figured out, right now I am trying to do a foreach loop, I want this script to read a file that have some hosts in it and save the config for each one:

Here is the code that I am trying:

Code:
#!/usr/bin/tclsh
package require Expect
log_user 0
match_max -d 10000000
set timeout 30

set tdate [clock format [clock seconds] -format %Y%m%d]

#set host 192.168.255.100
set user mktbk\r
set pass password\r


foreach {host} {argv0} {





set name $tdate-$host
spawn telnet $host

expect "Login: "
exp_send $user

expect "Password: "
exp_send $pass

expect "> "
exp_send "export\r"

expect "> "
exp_send "quit\r"
expect eof

set fd [ open $name w ]
puts $fd $expect_out(buffer)
close $fd

}

The error that i get is:

Code:
[alex@samba scripts]$ ./script.sh host.txt 
send: spawn id exp4 not open
    while executing
"exp_send $user"
    ("foreach" body line 11)
    invoked from within
"foreach {host} {argv0} {





set name $tdate-$host     
spawn telnet $host

expect "Login: " 
exp_send $user

expect "Password: "
exp_send $pass

exp..."
    (file "./script.sh" line 14)
[alex@samba scripts]$

Got any ideas?

Thanks

uruk-save

uruk-save(8)						      SYSTEM ADMINISTRATION						      uruk-save(8)

  NAME
      uruk-save - save uruk rc configuration in iptables-save-style format

  SYNOPSIS
      uruk-save [-6 (save ip6tables rules)]

  OPTIONS
      -6 (save ip6tables rules)
	Don't save iptables rules but save ip6tables rules, for IPv6 filtering.

  DESCRIPTION
      uruk-save  saves	the  IPv4 rules in /etc/uruk/rc in iptables-save(5)-style format, without invoking iptables(8). If the -6 option is given,
      the IPv6 rules (if any) in /etc/uruk/rc are saved, in ip6tables-save(5)-style format. It	prints	output	to  stdout;  suggested	invocation
      therefore is

       # uruk-save > /var/lib/uruk/iptables/active

      or

       # uruk-save -6 > /var/lib/uruk/ip6tables/active

      .  This script is useful if you don't like the default behaviour of the uruk init script, and would like it to load the current uruk rc file
      instead of the current active file. Please note: generally you don't need to invoke this script manually: the init script which  comes  with
      uruk is suitable for most cases, it invokes uruk-save if needed.

  WARNING
      Just as uruk, in order to keep the uruk-save script small and simple, the script does very little error handling. It does not check the con-
      tents of the rc file in any way before executing it. When your rc file contains bogus stuff, uruk-save will very likely behave in unexpected
      ways. Caveat emptor.

      Things will likely break if you do fancy stuff in an rc hook file. For instance, uruk-save saves the filter table only. If you define mangle
      or nat tables, things will break.

      If your rc file is in verbose mode (i.e. it features set -x) or in no-act mode (i.e. it features iptables='echo iptables'), uruk-save fails.
