I collect my experiences on http://www.linuxintro.org. You can, too.

Did you know you can control your Linux server via a browser?

comment Finding Out Serial Port Address in Linux?
how do you mean, they are both using /dev/ttyUSB0 but their addresses are different? How do you send something to /dev/ttyUSB0, address 42?

comment .bashrc and .bash_profile not executed
How do you start a new terminal? If you start it by clicking onto an icon this should be okay as this will start a non-login shell. Are you sure you are inside a bash shell? Type echo $SHELL, the system's response should be /bin/bash. On linuxintro.org/wiki/Boot_process#user_starts_a_shell I describe that the process sourcing .bashrc is login. Can you just call bash and see if .bashrc is being executed?

comment How does Linux load the 'initrd' image?
great explanation! So this is why I have to call the first disk's first partition hd0,0 in grub, /dev/sda1 in Linux and why both don't necessarily match.

comment Device in fstab not mounting at boot
could this be an iscsi device or fc over ethernet? In this case it will not come up because /etc/fstab is mounted before the network service is started. To circumvent this, use the option _netdev.

comment Large ext4 partition ridiculously slow when writing
please paste the output of iostat -x on the slow and a normal server. Please paste vmstat 10 while writing so we see how much IOwait is on the system. Please do an strace on slow and normal servers to see performance like this: strace -c ls -R

comment Suse 11 vs. Suse 10 difference impacting terminal colors?
dot files are not alone, they have global brothers and sisters, e.g. under /etc/profile.d and /etc/bash.bashrc, I tried to find them all in my blog linuxintro.org/wiki/Boot_process#user_starts_a_shell

comment How to configure a computer as a hotspot?
yikes! With my iwlwifi device I get exactly the error that you describe. I could work around this by using a USB WLAN stick from Conceptronic... however I need to improve and come back here I see. Hope the USB WLAN stick helps so long for you.
