Disabling UUCP ?

Philip Chan_1 — Tue, 22 Aug 2000 03:15:12 GMT

For security reasons we are considering to disable the uucp service. Can someone tell me what the consequence will be? and perhaps what other services and sub-systems have dependency on it?

Thanks
Philip

UUCP is used for transering files, executing commands on remote systems and sendind mail and news over serial dial-up lines. If you do not need any of those, you should not have any problem. No other services depends on it. Predictive software might need it but I don't think you are using predictive in a high securited box.

To state it simply, UUCP was the protocol used to move data around before the days of lans, wans, and the internet. Predictive software may use it, but I would think that HP should have some alternative methods available in these days of HAO. If you are using Predictive, a call to support would be in order. You can probably shut it down and lock it out without any impact. I don't know anyone that uses it otherwise these days.

"Execute remote commands ...", I thought that is done by the rexecd, does it mean rexecd uses uucp inside?

rexecd doesn't use uucp. reexecd is based on exec service.
As Tim said, it was on fashion in the old days.
Execute remote commands via serial connection.
I do have a box with uucp disable and is just fine.

Hello Phillip,
since UUCP (it's setup, at least) is used for everything controlling modems,
first check, if you do something with modems; like SLIP, or so...
Even then, if you are only going "outside" disbling the accounts of "uucp",
and "nuucp" (and the like) won't be disturbed.
HTH,
