comment Restrict SSH server tunneling port
I want the wildcard on the host, not the port. Seems "*:80" doesn't work.

comment Unix tool to output first n characters in an UTF-8 encoded file
iconv (the one included in glibc) has a bug of buffering the whole input before making any output. This has a huge performance impact. Nevertheless, your approach works.

comment TCP/UDP hole punching from and to the same NAT network
Just found out them to the same thing. You can easily check it by running a STUN client, such as sourceforge.net/projects/stun.

comment possibility of swap space has larger data in it than in my physical memory
There's nothing wrong with swap consumption being more than physical memory consumption. When an application, which resides in physical memory, quits, physical memory consumption is reduced, but swap consumption remains the same.

comment Execute background program in bash without job control
Hi Fran, try this. 1. vim foo; 2. gedit bar &; 3. disown; 4. fg. Step 3 disowns vim and step 4 brings gedit to foreground. After reading bash manual, I still don't know why bash considers vim as the current job in step 3.

comment Execute background program in bash without job control
After using it for sometime, I couldn't get used to it. The problem is I have to specify the job number. disown with no argument doesn't detach the previous background job, but the "current job", which I found strangely defined.
