Hi,
attached to this email are
dllogin
dlrancid
which are modified versions of fnrancid and fnlogin. These work with a
number of the D-Link models which we have here:
# DES-3010F - success (telnet, ssh)
# DES-3052P - success (telnet, ssh, ... a little slow)
# DES-3526 - success (telnet, ssh)
# DES-3550 - success (telnet, ssh)
# DES-3250TG - fail (there's no command to print config)
# DGS-3324SR - success (telnet, ssh)
# DGS-3100 - fail (but probably not too big a job to fix)
This is just a first go, but it's working well enough for us to use now. If
anyone has feedback, I'd love to hear it.
The only other modification was to add
'dlink' => 'dlrancid',
to %vendortable in rancid-fe and then use "dlink" to describe switches in
router.db.
Thanks for rancid, we're already seeing benefits.
Gavin

#
# dllogin - D-Link login
# This script is very much a hack based on the existing code, but it works for us.
#
# Thus far we have tested this on the following D-Link Switch models:
#
# DES-3010F - success (telnet, ssh)
# DES-3052P - success (telnet, ssh, ... a little slow)
# DES-3526 - success (telnet, ssh)
# DES-3550 - success (telnet, ssh)
# DES-3250TG - fail (there's no command to print config)
# DGS-3324SR - success (telnet, ssh)
# DGS-3100 - fail (but probably not too big a job to fix)
#
# Known bugs/issues:
# - line wrap problems cause newlines within config lines at 80 chars wide on
# some models (DES-3010F)
# - ssh can be quite slow on these units and we've even had anecdotal evidence
# that the load on the switches can occasionally cause packet loss. We
# generally use telnet for this reason and all is fine.
