SLATTACH(8) OpenBSD System Manager's Manual SLATTACH(8)NAME
slattach - attach serial lines as network interfaces
SYNOPSIS
slattach [-hm] [-s baudrate] ttyname
DESCRIPTION
The slattach command is deprecated. Please use the ldattach(8) command
instead.
slattach is used to assign a tty line to a network interface, and will
attach the named tty line to the first available slipdevice that is
configured and up.
The following operands are supported by slattach:
-h Turn on RTS/CTS flow control. By default, no flow control
is done.
-m Maintain modem control signals after closing the line.
Specifically, this disables HUPCL.
-s baudrate Specifies the speed of the connection. If not specified,
the default of 9600 is used.
ttyname Specifies the name of the tty device. ttyname should be a
string of the form ``ttyXX'', or ``/dev/ttyXX''.
In addition, the following flags to ifconfig(8) control various
properties of the link:
link0 Turn on Van Jacobsen header compression.
-link0 Turn off header compression.
link1 Don't pass through ICMP packets.
-link1 Do pass through ICMP packets.
link2 If a packet with a compressed header is received,
automatically enable compression of outgoing packets.
-link2 Don't auto-enable compression.
Only the superuser may attach a network interface.
To detach the interface, use ``ifconfig interface-name down'' after
killing off the slattach process. interface-name is the name that is
shown by netstat(1).
EXAMPLES
# ifconfig sl0 10.0.0.1 10.0.0.2 link0 link2 up
# slattach ttyh8
# ifconfig sl1 192.168.0.1 192.168.0.2 link0 up
# slattach -s 4800 /dev/tty01
DIAGNOSTICS
Messages indicating the specified interface does not exist, the requested
address is unknown, the user is not privileged and tried to alter an
interface's configuration.
