The sliplogin utility is used to turn the terminal line on standard input (or device) into a Serial Line IP (SLIP) link to a remote host. To do this, the program searches the file /etc/sliphome/slip.hosts for an entry matching loginname (which defaults to the current login name if omitted). If a matching entry is found, the line is configured appropriately for slip (8-bit transparent i/o) and converted to SLIP line discipline using the optional line discipline parameters.
The optional line discipline parameters consist of one or more of the following; 'normal', 'compress', 'noicmp', or 'autocomp' which correspond respectively to 'use normal line discipline' (no header compression), 'enable VJ header compression', 'throw away ICMP packets', and 'auto enable VJ header compression' (only if the remote end of the link also supports it).
Then a shell script is invoked to initialize the slip interface with the appropriate local and remote IP address, netmask, etc.
The usual initialization script is /etc/sliphome/slip.login but, if particular hosts need special initialization, the file /etc/sliphome/slip.login. loginname will be executed instead if it exists. The script is invoked with the parameters
