The following options are available.
If uucico receives a SIGFPE (see kill.1 it will toggle the debugging on or off.
The uucpd server supports uucp connections over networks. The uucpd daemon listens for service requests at the port indicated in the ``uucp'' service specification; see services(5). The server provides login name and password authentication before starting up uucico for the rest of the transaction.
The uucico daemon is commonly used either of two ways: either run periodically by cron.8 to call out to remote systems, or as a ``shell'' for remote systems who call in. For calling out periodically, a typical line in crontab might be:
0 * * * * uucp /usr/lib/uucp/uucico -r1
This will run uucico every hour in master role. For each system that has transfer requests queued, uucico calls the system, logs in, and executes the transfers. The file L.sys.5 is consulted for information about how to log in, and L-devices.5 specifies available lines and modems for calling.
For remote systems to dial in, an entry in the passwd.5 file must be created, with a login ``shell'' of uucico. For example:
uucp:*:4:4::/usr/spool/uucppublic:/usr/lib/uucp/uucico
The UID for UUCP remote logins is not critical, but it should differ from the UUCP Administrative login. The latter owns the UUCP files, and assigning this UID to a remote login might, were uucico NOT used as the login ``shell,'' pose a security hazard.
