# in.uucpd(8)

run uucico from inetd

## NAME

uucpd, in.uucpd - run uucico from inetd

## SYNOPSIS

**/usr/sbin/in.uucpd**

## DESCRIPTION

**Uucpd** is a program run from **inetd** when inetd detects a connect on the uucp port (usually *540* ). It uses pam to authenticate users. If access by pam would be granted, and the first six letters of the basename of the shell match the word *uucico* then an utmp and wtmp entry are written and the users shell is invoked. The uucpd process stays around until **uucico** exits, then updates the utmp and wtmp files once more.

## OPTIONS

None.

## NOTES

Uucico also has the possibility to check for loginname/password itself directly, instead of needing a frontend uucpd. However that does not work if the system has shadow passwords, or any other way of authentication which requires root privileges. Also, no utmp/wtmp records are written.

If you want to define UUCP accounts outside the password file (eg through */etc/uucp/passwd* ) you need to call **uucico -l** from */etc/inetd.conf* instead of **in.uucpd** .
