I need to setup rancid to backup many Alcatel Omniswitch.

It looks like alulogin is wrote for old version of alcatel Omniswitch,

I did modifications about prompts and "no more" commands to make it compatible.

Everything run fine until I run the first command :

rancid at RSFRGUY-TESTMON:~/bin$ ./alulogin -c "show cmm" SW-ALCATEL-TEST1
spawn telnet sw-alcatel-test1
Connected to SW-ALCATEL-TEST1.
Escape character is '^]'.

Error: TIMEOUT reached

Here is what I get from debug for the same command:

expect: does "  MAC Address:

expression "\u0008+"? (No Gate, RE only) gate=yes re=no

"^--More--[\r\n]+"? Gate "--More--*"? gate=no
"[\n\r]+"? (No Gate, RE only) gate=yes re=yes
expect: set expect_out(0,string) "\r\n\r\n\r\n\r\n"
expect: set expect_out(spawn_id) "exp6"

expect: timed out

The prompt is always "-> ", I've done modifications on the alulogin file.

Here are the modifications I made :

<     send "environment no more\r"
>     send "no more\r"
<       set u_prompt "(Username|Login|login|user name|User):"
>       set u_prompt "(Username|Login|login|user name|User) :"
<       set p_prompt "(\[Pp]assword|passwd|Enter password for \[^ :]+):"
>       set p_prompt "(\[Pp]assword|passwd|Enter password for \[^ :]+) :"
<       set e_prompt "\[Pp]assword:"
>       set e_prompt "\[Pp]assword :"
>     set prompt [find prompt $router]
>     if { "$prompt" == "" } {
>         set prompt "-> "
>     }
<       -re "\[\r\n]+"          { exp_continue; }
>       #-re "\[\r\n]+"         { exp_continue; }
>         -re "^.$prompt" { exp_continue }

I can't find what can be the problem, i'm new to rancid and not an
expert in Perl.

Can you help me ?

Thank you.
