Trouble with alogin

Hey!

I'm finally trying to get our Alteon's incorporated into rancid.
When I run alogin against one of them, I get this output:

------------------------------------------------------------
[Main Menu]
info - Information Menu
stats - Statistics Menu
cfg - Configuration Menu
oper - Operations Command Menu
boot - Boot Options Menu
maint - Maintenance Menu
diff - Show pending config changes [global command]
apply - Apply pending config changes [global command]
save - Save updated config to FLASH [global command]
revert - Revert pending or applied changes [global command]
exit - Exit [global command, always available]

>> Main# expected boolean value but got ""
while executing
"if {[login $router $ruser $userpswd $passwd $prompt $cmethod $cyphertype]} {
continue
}"
("foreach" body line 59)
invoked from within
"foreach router [lrange $argv $i end] {
set router [string tolower $router]
send_user "$router\n"

# Figure out prompt.
set prompt ">> ..."
(file "/home/rancid/bin/alogin" line 421)

It successfully logs in, but then it seems to croak. Any ideas? I don't
speak expect, so use small words. :)

Thanks!

-David

i suspect that there is a return statement in the login procedure that
doesnt return a number value or it's an implicit return perhaps due to
an empty $cmethod variable.

what version of rancid?

try the attached patch

cd rancid-2.2/bin
patch < file

if it fixes the problem expect bomb-out, then i;m slightly confused as to
how it manages to login but ends up here.

It no longer gives the error, but it doesn't stay logged in:

revert - Revert pending or applied changes [global command]
exit - Exit [global command, always available]

>> Main# bash-2.02$
bash-2.02$

That doesn't seem good, since you can't go on to execute commands.
By the way, the switch is running WebOS 9.0.38-SSH. Don't know if that
will matter. Oh, and I'm not using ssh to get to it...just telnet.
My .cloginrc is pretty simple...it just has 'add password <alteon>
<password>'. Nothing exciting there.
