Troubleshooting

Following are some of the problems which may be encountered due to

improper configuration of ports.

Excessive Frequent

getty Spawning

Problem:

A console message similar to the following appears:

‘tty1a1’

getty keeps dying. There may be a problem

Cause:

This message usually indicates that the incoming CD signal connected to

a modem control port with

CLOCAL set keeps toggling. The result is

that the getty process dies because the

loss of carrier spawns a new

getty. If the system detects a getty process spawned too frequently on a

port, it prints this message and eventually fails to spawn a new getty

until an internal retry time has been reached or the port is disabled and

then re-enabled.

Terminal Login Problems

Problems:

• No login prompt

• Garbled message

• Problems logging in

Causes:

• Port is not enabled

• Port is set for wrong speed, parity, character size, etc

• Cabling problem

• Hardware problem
