Troubleshooting UUCP

Troubleshooting UUCP

Before troubleshooting the UUCP system, make sure that the physical connection works. If you are connecting to UUCP with a modem, verify that the modem is installed and configured correctly. See ``Troubleshooting modems'' in the SCO OpenServer Handbook. If you are using a direct line, make sure that the computers are connected correctly -- use the instructions in ``Connecting two local systems using a direct wire''.

NOTE: If you are configuring an outbound UUCP connection over a modem, cu must function for UUCP to work.

If the hardware is correctly configured but a session is repeatedly failing for no known reason, the first troubleshooting step should be to run uutry and save the output log. The log (stored in /tmp/hostname, where hostname is the remote host's name) contains a listing of the steps uucico went through, and may indicate where the failure occurred.

uucico produces 11 levels of debugging output, from 0 to 10. Level 9 is the most verbose standard mode, and is generated when uucico receives the command line option -x9 (you can also pass this option to uutry when testing the uucico connection to a given site). Level 10 is identical to level 9, except that the output from the ``g'' or ``G'' protocols is written to a file in /tmp for future reference.
