Problem with Cisco 1900's and RANCID v2.3.2a

[Roderick B. Greening]

I downloaded the clogin.in file from ftp.shrubbery.net and it works for
1900's, but the one packaged in the tar ball doesn't.

I did a diff, and it appears as though some things were shuffled around in
the section dealing with the "--More--".

If this is an expect issue, can someone explain why the clogin.in file on
the ftp server appears to work and what was broken in expect that would need
to be patched.

I am running Mandrake Linux 10.1 and have installed the following expect RPM
and not applied any specific patch to expect: expect-8.4.5-6mdk

Running expect -v it returns: expect version 5.38.0

I also have the following RPM's for TCL:

tcl-8.4.5-6mdk
libtcl8.4-8.4.5-6mdk

Here's the diff -u between the rancid 2.3.2a version of clogin and the
standalone one that works from ftp.shrubbery.net/pub/rancid

Thanks.

PS: I can successfully telnet to the device. I can perform "sh version" for
example. It's just the pager ("--More--") that I can't get past by using the
packaged clogin script.

my best guess is that you're running linux or solaris and did not compile
expect with the patch on the rancid web page.
