TCP/IP problems with a SLIP network interface
In general, the most effective method for debugging problems with a Serial Line Interface Protocol (SLIP) interface is to retrace your configuration, verifying each step.
However, you can also:
- Verify that the slattach process is running and using the correct tty port by issuing the ps -ef command. If it is not, run the slattach command. (See Configuring SLIP over a modem or Configuring SLIP over a null modem cable for the exact syntax you should use.)
- Verify that the point-to-point addresses are specified correctly
by entering the smit chinet fast path.
Select the SLIP interface. Make sure that the INTERNET ADDRESS and DESTINATION ADDRESS fields are correct.
If the modem is not functioning correctly:
- Make sure that the modem was installed correctly. See the modem installation manual.
- Verify that any flow control the modem does is turned off.
If the tty is not functioning correctly, verify that the tty baud rate and modem characteristics are set correctly in the configuration database by entering the smit tty fast path.
