If you want see information from your shell (like current directory, user and hostname) in xterm window title just place the following lines in your ~/.zshrc file:
case $TERM in
*xterm*)
precmd () {print -Pn "\e]0;%n@%M: %~\a"}
;;
esac
P.S.: I use “*xterm*” in this example, because i have TERM like “color_xterm”, “xterm-sun” and “xterm-hp”, see /etc/termcap file.
At work I got two new toys. 
DKVM-16 and DKVM-IP1. Testing in progress…
P.S.: I’m waiting for Cisco Catalyst 3560.
Here is tip how to make one ssl certificate for many Common Names (CN).
You need add following strings to your openssl.cfg:
[ req_distinguished_name ] 0.commonName_default = www.first-domain.com 0.commonName_max = 64 1.commonName_default = www.second-domain.com 1.commonName_max = 64
..and use this config file for making certificate.
nc(1) can be used for simple and fast network scan. Here is sample of localhost scan (ports range: 1-1024).
$ nc -v -z 127.0.0.1 1-1024
localhost [127.0.0.1] 80 (www) open
localhost [127.0.0.1] 25 (smtp) open
localhost [127.0.0.1] 22 (ssh) open
This patch add D-Link DWL-G630 (H/W Ver. D1) support to ath(4) driver in OpenBSD-current kernel.
Before patch:
Atheros Communications, Inc., AR5001-0000-0000, Wireless LAN Reference Card, 00 (manufacturer 0×271, product 0×12) vendor “Atheros”, unknown product 0×001a (class network subclass ethernet, rev 0×01) at cardbus0 dev 0 function 0 not configured
After patch:
ath0 at cardbus0 dev 0 function 0 “Atheros Communications, Inc., AR5001-0000-0000, Wireless LAN Reference Card”: irq 10
ath0: AR5213 7.8 phy 4.5 rf2112a 5.6, FCC2A*, address 00:13:46:6e:a4:ef
Use OpenSSH port forwarding to browse web from public place.
ssh(1) can act as a SOCKS server. SOCKS4 and SOCKS5 protocols are supported. All you need is shell access to remote machine.
Example:
ssh -D 4545 user@IP
Now you can specify “localhost” as SOCKS host and “4545” as SOCKS port in connections settings of your browser.
