Because the login process is similar enough to match the regexps?

Actually, for most of my F kit, the login prompt is:

Please Enter Login Name:

and that doesn't match with the clogin I have.  However, I have one device 
that happens to be just protected with a password rather than a 

/usr/local/libexec/rancid/clogin ip.ad.re.ss
spawn telnet ip.ad.re.ss
Trying ip.ad.re.ss...
Won't send login name and/or authentication information.
Connected to ip.ad.re.ss
Escape character is '^]'.

User Access Verification

Please Enter Password:

User login successful.

so in at least that circumstance, they are similar enough.  Of course it 
all breaks if rancid starts sending cisco-esque commands rather than 
foundry-esque ones.

clogin itself works with quite a lot of stuff that roughly looks 
cisco-ish, as they all tend to have a Username/Password prompt that 
matches the fairly generous clogin regexp, and tend to have a CLI prompt 
that ends with '>'.  It all goes wrong afterwards ...

(I do think it a source of confusion for the newcomer that 'rancid' the 
project now supports many types of device, but while in v2 the Cisco login 
script is clogin, the Cisco command script is not crancid, but just plain 
rancid - all the rest have a matching prefix for the *login and *rancid 
scripts afaicr).
