[rancid] rancid issues with IOS XR

HI all,

Hope someone can help on this issue.

I seem to be having an issue logging onto IOS XR routers using clogin, or the xrrancid patch as described by previous forums.

the output i get when using -autoenable or configuring the devices in my .cloginrc file returns the same output.

It seems to skip the initial expect sequence for Username: and then returns with another auth reques, after the second prompt the expect script appear to have died, as i can then type in my own authentication details.

User Access Verification

Username:

User Access Verification

Username:
telnet> quit

Any ideas ?

I have tried this on rancid 2.3.2a7 and the new 2.3.3, but still no luck.

Thanks,

Drikus

you'll have to share the o/p of clogin -d hostname with us.

This looks similar to a problem we had where the '#' symbols in our
banner were being mistaken for the '#' in the enable prompt and
confusing rancid. One of my colleagues applied this patch before I
was involved in our rancid install:

423a428,435

-re ".+##########.+Verification" {
# Account for the hosed up banner via telnet
exp_continue
}
-re ".+##########.+" {
# Account for the hosed up banner via ssh
exp_continue
}

This may be a silly patch but it's worked for us and I've never had to
reevaluate it. If you used something like this you might have to
change the number of contiguous hashes based on the output you sent.

you'll have to share the o/p of clogin -d hostname with us.

This looks similar to a problem we had where the '#' symbols in our
banner were being mistaken for the '#' in the enable prompt and
confusing rancid. One of my colleagues applied this patch before I
423a428,435

-re ".+##########.+Verification" {
# Account for the hosed up banner via telnet
exp_continue
}
-re ".+##########.+" {
# Account for the hosed up banner via ssh
exp_continue
}

nothing comes to mind thats universal. i thought
# Default prompt.
set prompt "(>|[^#]#| \\(enable\\))"
but that doesnt cover all cases. sorry, just dont use # or > in the
banner; ! perhaps.

--------------------------------------

Removing the hashes's seems to work, however , the exact same banner exists on all other IOS routers & switches without issues. It's just with IOS XR routers that I have, that it appears to break

i presume that the IOS routers are not auto-enabling, but the XR is.

That would be correct, the IOS routers are not auto=enabling. Removing the #'s from my banner works , but would mean that I would need to update at least 200+ core routers to have a set standard across all routers, or go with a slight difference on my IOS XR routers.

As clogin works today, '#' in a login banner together with -autoenable
won't work.

You are not totally out of luck though: you can easily change the
login banner on the IOS-devices with clogin :-)

you can use clogin to modify the ones where clogin works and if you hack
clogin for the time being as the other user suggested you can modify all
of them.
