slstat -- report serial line IP statistics
slstat [-i interval] [-vr] [unit]
The slstat utility reports certain kernel statistics kept about serial
line internet protocol traffic.
The options are as follows:
-i Repeat the display indefinitely every interval seconds. If no
interval is specified, the default is 5 seconds.
-v Verbose display of extra fields of information.
-r Display all values in rate per second rather than amount per
unit Is number specifying the SLIP interface, or a SLIP interface
name. The default unit is 0 for interface sl0.
By default, slstat displays the following information:
in bytes received
out bytes sent
pack packets received or sent
comp compressed packets received or sent
uncomp uncompressed packets received or sent
unknwn inbound packets of unknown type
toss inbound packets tossed because of error
other all other inbound or outbound ip packets
err input or output errors
search searches for connection state
miss times we could not find a connection state
coll collisions with end of clists. If you get many collisions (more
than one or two a day) you probably do not have enough clists and
you should increase nclist in param.c.
slstat -i 5
will print what the system is doing every five seconds.
