Adjust to suit your needs. Currently this would kill any whois process running for more than 30 seconds or more than 1 minute.
Add it as a cronjob. The motivation is that some commands have no timeout and just end up using up CPU and memory for no reason while never exiting to free resources.
IFS=$(echo -en "nb")
for pid in `ps aux|grep whois`; do
This is useful if you have a bunch of images/scans where the same area at the top needs to be chopped.
Sometimes the -trim option (such as the case of white space on top)is wrong and ends up cropping the image and losing some text.
ImageMagick's convert is very useful but tricky to find some things out as I find it to be less than intuitive sometimes.

error: Could not locate RPC credentials. No authentication cookie could be found, and no rpcpassword is set in the configuration file
This is usually because the .cookie file cannot be read by the user you are running Litecoin or Bitcoin client/daemon as.
You can adjust the permissions of the file so that the user or group they are apart of has read permissions.

kernel: [10186978.064405] TCP: time wait bucket table overflow (CT3)
Varying opinions are out there but in general it seems like the most common culprit is a lack of privvmpages, with a modern OpenVZ system the best way is to set privvmpages as equal to what your RAM is and this has resolved the messages on another system.
If it's truly a TCP issue you can adjust the following parameters:........
iptables -t nat -A PREROUTING -p tcp -m multiport --dports 80,443,2068,8192 -j DNAT --to-destination 192.168.1.175
Just adjust the "--dports" to the ports you need and the --to-destination to the destination IP (note it must be on the same network as the server running iptables........
libguestfs tools howto guide for managing virtual machine images.
libguestfs-tools aka guestfs tools has a lot of tools that make this very easy for you. You can easily mount partitons from an image with some of the commands below.
To mount a partition
#mount the kvmuser102821.img image and the /dev/sda1 partition from it to the local directory "mount"
guestmount -a kvmuser102821.img -m /dev/sda1 mount
First of all to find your IP you can hold the "X" button for a few seconds and it will print out the DHCP IP.
Another way to find the IP that I prefer is to login to your router or switch and find a hostname that says something like "SEC001599CD2948" which will be your Samsung printer (at least for the C3xx or C4xx series of Samsung printers).
The login and password for Samsung Syncthru Webservice:........
First of all if you're getting this error it is a result of extreme database activity. If you aren't expecting it or it doesn't make sense to you 99% of the time this is a database driven script being exploited (some common examples I see often are things like phpBB being hit by dozens, hundreds or thousands of bots making constant DB write requests).
The easiest way to identify this is to restart MySQL and then run the third party tool "mtop" and you'll see all........
cat /etc/some.conf|grep -Ev '^#|^;|^$'
This assumes that comments start with # or ; (adjust as necessary). Also note that the ^$ omits blank lines.........
This is important if you need public access to internal IPs such as at your office and don't want to use a VPN just to SSHinto different servers:
Below forwards the port "10001" to the IP220.127.116.11 on port 22 (of course adjust it to your needs).
iptables -t nat -A PREROUTING -p tcp --dport 10001 -j DNAT --to-destination 18.104.22.168:22
Remember to enable MASQUERADE on your NAT IPs or they won't be able to talk to the outside world (........
lines=`cat linesfile.txt|sed -n "$start","$increment"p`
The secret here is the power of sed.
Basically the example above would take the first 5 lines from the file. You could change it though to say take 20 lines starting from the 5th line by adjusting the start and increment values.........

route add -net 22.214.171.124 netmask 255.255.255.0 eth0
Of course adjust as you need (eg. the 126.96.36.199 should be changed to the subnet you need access to and eth0 should be changed to the network device that you want that subnet routed through). I also use the /etc/sysconfig/rc.local script and add the above into it (remember that this route only gets added AFTER all other init scripts have finished though).........

I've had an old Blackberry for a few years and I was ready to spend some serious cash on a nice Nokia. I love the idea of the Linux based Symbian S60 OS, so I was looking at phones like the E63, E71 (both are basically the same, at least CPU/screensize although E71 is thinner, has a 3MP camera, has GPS, and has dedicated buttons to adjust the volume).
Then Iheard about the N97 and what a revolution it was supposed to be and it was even compared to iPhone.
