Alan,
Thank you . Please see the below,
1. Can telnet to device and authenticate manually
2. /home/eserica/rancid/bin/hulogin -d 10.3.4.5 logs in successfully, and enables properly. Prompt is correct as well
3. /home/eserica/rancid/bin/hulogin -t 90 -c"display current-configuration ; display version" 10.3.4.5 runs cleanly. commands are run neatly. automatic login and logout4.[eserica at netflow logs]$ /home/eserica/rancid/bin/h3crancid -d 10.3.4.5
executing hulogin -t 90 -c"display version ; display current-configuration" 10.3.4.5
executing hulogin -t 90 -c"display version ; display current-configuration" 10.3.4.5
sh: hulogin: command not found
10.3.4.5: missed cmd(s): display current-configuration,display version
10.3.4.5: missed cmd(s): display current-configuration,display version
10.3.4.5: End of run not found
10.3.4.5: End of run not found
The router.db
10.3.4.5:huawei:up
The rancid-fe
'huawei' => 'h3crancid',
Don't understand why am getting such an output from /home/eserica/rancid/bin/h3crancid -d 10.3.4.5
Any comments on the above?
Still the same logs.
Eserica

The approach to fixing this is always the same, at this point nothing
rancid is outputting helps debug in the slightest - all it says is that
something went wrong, but we already know that.
Do the following:
1. telnet to device and check you can auth manually
2. "hulogin <device>" and check it logs in and enables properly, and
that the prompt etc on the screen is correct
3. run "hulogin -t 90 -c"display current-configuration,display version"
<device>" and check that the commands do actually run correctly
4. run "hurancid -d <device>" - this dumps a *complete* log in the
current directory containing more info than the regular log you quoted
and often reveals the problem (but not always).
But first a few prior steps need to be verified:
- the command in #3 I pasted from your log output, and that has comma
separators. Your device might need semicolons, I have no idea as I don;t
know that vendors stuff
- the relevant line in router.db must contain the appropriate type
string in field 3
- you will have had to edit rancid-fe and add a line for huawei to a
perl hash. Without this, rancid-run doesn't know what parser script to
call and it cannot work.
- the device you have must be supported by the script you are using;
just because Huawei made it is no guarantee it works similarly to
anything else they might have made.
If all of that checks out, then we need to look into the running perl
itself.
I believe we've been over most of this before, I don't recall getting a
definitive answer. You really do need to go through all these steps as
given, nothing else is going to get to the root of your problem.
