slattach(8)slattach(8)NAMEslattach - Attaches a serial line to a network interface
SYNOPSIS
/usr/sbin/slattach [+{c | e | i}] [-{c | e | i}] ttyname [baudrate]
OPTIONS
Enables (+) or disables (-) TCP header compression. Enables (+) or
disables (-) automatic TCP header compression. If enabled and the
remote system is using TCP header compression, TCP header compression
is automatically enabled on the local system. If both local and remote
systems have enabled this option, TCP header compression is not used.
One system must force the use of TCP header compression. Enables (+)
or disables (-) ICMP traffic suppression. If enabled, ICMP traffic
(like that generated by ping(8)) is not allowed to pass over the SLIP
connection.
When the system is booted, all options are initially disabled. Once a
option is enabled, it remains enabled until the system is rebooted or
until another slattach command is issued with the option disabled.
OPERANDS
The name of any valid tty device in /dev. You can use either the full
pathname such as /dev/tty01 or the name in /dev such as tty01. This op‐
erand is mandatory. Specifies the connection speed, for example: 9600.
This operand is optional.
DESCRIPTION
The slattach command assigns a tty line to a network interface, allow‐
ing terminal devices to communicate across a network.
The tty line is attached to the first available network interface (sl0,
sl1, ...). Before issuing the slattach command, the network interface
must already be configured with the local and remote addresses of each
end of the SLIP connection (see ifconfig(8)).
Only a person with superuser authority can attach a network interface.
To detach the interface, use the ifconfig interface_id down command
after terminating the slattach process. interface_id is the name that
is shown by the netstat command.
NOTES
The slattach command requires the Serial Line Internet Protocol (SLIP),
which the kernel must support. If making a SLIP connection to another
Tru64 UNIX system, both systems must run slattach. If making a SLIP
connection to a system not running the Tru64 UNIX operating system, the
other system must support the SLIP protocol.
EXAMPLES
Use the following command to attach a tty device to a network inter‐
face: % /usr/sbin/slattach /dev/tty01 4800
This command attaches tty01 to a network interface to be used by
the Serial Line Internet Protocol (SLIP). The connection speed
is 4800 baud. Use the following command to attach a tty device
to a network interface at 19200 bits per second (bps) with TCP
header,:enter: % /usr/sbin/slattach +c -i /dev/tty01 19200
