Hitchhiker's Guide to Openbsd

Using S/Key with ssh(1) and telnet(1)
Using S/Key with ssh(1) or telnet(1) is done in pretty much the same fashion as with ftp--you simply 
tack ":skey" to the end of your username. Example: 
$ ssh -l ericj:skey localhost
otp-md5 98 oshi45821
S/Key Password: SCAN OLGA BING PUB REEL COCA

Welcome to OpenBSD: The proactively secure Unix-like 
operating system.
Please use the sendbug(1) utility to report bugs in the 
system.
Before reporting a bug, please try to reproduce it with the 
latest
version of the code. With bug reports, please try to 
ensure that
enough information to reproduce the problem is enclosed, 
and if a
known fix for it exists, include that as well.

8.12 - What OpenBSD platforms support SMP?
(Symmetric Multi-Processor)
SMP is supported on the 
OpenBSD/i386
, 
OpenBSD/amd64
, 
OpenBSD/mvme88k
, 
OpenBSD/sparc64
 
(including the UltraSPARC T1 processors), 
OpenBSD/macppc
, 
OpenBSD/sgi
 (Octane only), and 
OpenBSD/hppa
 (-current only), platforms. 
A separate SMP kernel, "
bsd.mp
", is provided with the install file sets. If multiple processors are 
detected at install time, is automatically installed as the default boot kernel, 
/bsd
, and the single 
processor kernel is renamed 
/bsd.sp
. 
If you add additional processors to a system which was installed with only one processor, you will want 
to install the appropriate bsd.mp kernel, rename your existing 
/bsd
to 
/bsd.sp
, and rename 
/bsd.
mp
to 
/bsd
. 
It is hoped that other SMP-capable platforms will be supported in the future. On most other platforms, 
OpenBSD will run on an SMP system, but only utilizing one processor. The exception to this is the 
SPARC
 platform -- OpenBSD/sparc will sometimes require that extra MBus modules be removed for 
the system to boot.
