Expect script to save configuration from a router
Hy guys,

My name is Alex, i am new here and I hope to find some answers. I am trying to run a expect script to telnet to a mikrotik router, run a command (export), and save the output of that commant to a file (outputfile.txt). The problem is that only part of the output is saved to outputfile.txt.

Here is my code:

Code:
#!/usr/bin/expect -f
exp_internal 0
log_user 0
match_max -d 1000000

set timeout 30
spawn telnet 192.168.255.100
expect "Login: "
send "mktbk\r"
expect "Password: "
send "password\r"
expect "> "
send "export\r"
expect eof
puts [open outputfile.txt w] $expect_out(buffer)
expect "> "
send "quit\r"

I guess it's a buffer problem ..... got any ideas?

Thanks,
Alex

bb-services

BB-SERVICES(5)							File Formats Manual						    BB-SERVICES(5)

NAME

       bb-services - Configuration of TCP network services

SYNOPSIS

       $BBHOME/etc/bb-services

DESCRIPTION

       bb-services contains definitions of how bbtest-net(1) should test a TCP-based network service (i.e. all common network services except HTTP
       and DNS).  For each service, a simple dialogue can be defined to check that the service is functioning normally, and optional flags  deter-
       mine if the service has e.g. a banner or requires SSL- or telnet-style handshaking to be tested.

FILE FORMAT

       bb-services is a text file. A simple service definition for the SMTP service would be this:

	  [smtp]
	     send "mail
quit
"
	     expect "220"
	     options banner

       This  defines  a service called "smtp". When the connection is first established, bbtest-net will send the string "mail
quit
" to the
       service. It will then expect a response beginning with "220".  Any data returned by the service (a so-called "banner") will be recorded and
       included in the status message.

       The full set of commands available for the bb-services file are:

       [NAME] Define  the  name  of  the  TCP service, which will also be the column-name in the resulting display on the test status. If multiple
	      tests share a common definition (e.g. ssh, ssh1 and ssh2 are tested identically), you may list these in a  single  "[ssh|ssh1|ssh2]"
	      definition, separating each service-name with a pipe-sign.

       send STRING

       expect STRING
	      Defines the strings to send to the service after a connection is established, and the response that is expected. Either of these may
	      be omitted, in which case bbtest-net(1) will simply not send any data, or match a response against anything.

	      The send- and expect-strings use standard escaping for non-printable characters. "
" represents a carriage-return (ASCII 13),  "
"
	      represents  a  line-feed	(ASCII 10), "	" represents a TAB (ASCII 8).  Binary data is input as "xNN" with NN being the hexadecimal
	      value of the byte.

       port NUMBER
	      Define the default TCP port-number for this service. If no portnumber is defined, bbtest-net(1) will attempt to lookup the  portnum-
	      ber in the standard /etc/services file.

       options option1[,option2][,option3]
	      Defines test options. The possible options are
		 banner - include received data in the status message
		 ssl - service uses SSL so perform an SSL handshake
		 telnet - service is telnet, so exchange telnet options

FILES

       $BBHOME/etc/bb-services
