Yup; we try to support a large number of routers running many
versions of code with a small number of programs. E.g.: all junipers
are supported by jlogin/jrancid, even if this means that some routers
are sent commands that they don't support and if we are sending
commands that only work in older code. Another e.g.: clogin is
used for ciscos & a number of non-cisco routers.
It pains me to have some ciscos supported by rancid/clogin and other
ciscos by cat5rancid/clogin. At least both types use clogin.
The ideal would be to have one login program and one rancid program
& put the smarts into the program to figure out what its talking
As it is, we currently have 12 *login programs and 23 *rancid
programs; most of which share a fair amount of code. Trying to
keep them in sync & trying to make sure that changes that works on
one doesn't blow up another is a pain.
I'd much rather send 100 useless commands to a router than expand
the number of *login & *rancid programs we have, trying to taylor
each one to a particular type of router running a particular version
I think Heas' comment of working on the configurable rancid is the
way to go - fewer commands for us humans to remember; more smarts
in the code.
