Recently I noticed that my ssh login sequences took a long time (give or take 5 seconds). After disabling the “Automatic service discovery”, it returned to it’s normal (and fast) state.
Go to “System” -> “Network” -> “General”, and deselect the “Automatic service discovery”.
You can flash various wifi access points with openwrt. From then on you can even customize the device with packages you want. Like for instance a small http daemon or such.
Here we have the Linksys NSLU2 wich has it’s own “homebrew” firmware available at nslu2-linux.org. With this you can turn your small low cost storage device into a small linuxcomputer.

The TMPFS file system is activated automatically in the Solaris environment by an entry in the /etc/vfstab file. The TMPFS file system stores files and their associated information in memory (in the /tmp directory) rather than on disk, which speeds access to those files. This results in a major performance enhancement for applications such as compilers and DBMS products that use /tmp heavily.
The TMPFS file system allocates space in the /tmp directory from the system’s swap resources. This means that as you use up space in /tmp, you are also using up swap space. So if your applications use /tmp heavily and you do not monitor swap space usage, your system could run out of swap space.
Swap-Related Error Messages
These messages indicate that an application was trying to get more anonymous memory and there was no swap space left to back it.
application is out of memory

WARNING: Sorry, no swap space to grow stack for pid 100295 (myprog)
TMPFS-Related Error Messages
directory: File system full, swap space limit exceeded
This message is displayed if a page could not be allocated when writing a file. This can occur when TMPFS tries to write more than it is allowed or if currently executed programs are using a lot of memory.
directory: File system full, memory allocation failed
This message means TMPFS ran out of physical memory while attempting to create a new file or directory.
See TMPFS(7FS) for information on recovering from the TMPFS-related error messages.

Ever wanted to share ssh connections? You logged in the first time, but when doing the second you’re wondering: “Why didn’t it remember my credentials?”
You can share connections thru a simple config tweak…
Edit your .ssh/config:
There is a downside however: if the first connection is closed, then all connections are closed…
