[rancid] Custom Device Login File (mrvlogin)

[Keith Calligan]

Hi,

 

I'm trying to modify the existing mrvlogin script to work with MRV
terminal server devices.  It appears that this (original) script and
mrvrancid may have been written for another device by the same
manufacturer.  I've made some progress, but am having issues saving any
output and exiting completely.  

 

I'm issuing the following command

./mrvlogin -d -t 90 -c "show version" $devicename

 

Here is some debug information.  I'm showing the last line of the "show
version" and the parts that are failing.  The prompt for these devices
is set to "InReach:0 >".  The exit is getting sent, but I'm seeing lots
of empty lines trying to be matched ("").  Please note that I replaced
the real hostname with $device in this debug output.  

 

 

expect: set expect_out(buffer) " Software Version (Flash):
Software Version (Flash):
3.9.0

 Ppciboot Version:
3.9.0

InReach:0 >}

 

expect: does "" (spawn_id exp6) match regular expression "^[^\n\r

expect: set expect_out(0,string) "\r\n"

expect: set expect_out(spawn_id) "exp6"

expect: set expect_out(buffer) "exit\u001b[H\u001b[2J\r\n"

expect: continuing expect

expect: does "" (spawn_id exp6) match regular expression "^[^\n\r

"[\n\r]+"? no

expect: read eof

expect: set expect_out(spawn_id) "exp6"

expect: set expect_out(buffer) ""

write() failed to write anything - will sleep(1) and retry...

 

I'm still new to using Rancid so please bear with me.  If you need me to
send my mrvlogin script, I can do that as well.  I think I'm pretty
close to getting it working but not sure what I'm missing.  

 

 

Thanks,
