Hello guys

Today i install finger in my ubuntu machine, I want try to modded fingerd , but I saw that in the directory of finger there isn't any c file for modded it.

furthermore

I know that the fingerd daemon listen on the 79 port, but when i digit in the terminal

Code:

netstat -tulpn | grep 79

the output is the below text

Code:

  tcp 0  0  0.0.0.0:79   0.0.0.0:*   LISTEN -

Greetings,

Well, Ubuntu is a binary-based distribution, so it doesn't surprise me that it didn't give you the source code like you would get from a source-based distro like Gentoo, LFS or from Arch's AUR repository. If you want to play with the source code for fingerd, you can get it from http://ftp.linux.org.uk/pub/linux/Networking/netkit/ as a package called (as of this writing) bsd-finger-0.17.tar.gz.

Now, for the other question:
Not exactly sure why you are getting a dash for what should be the pid and name of the service by the flags you put to netstat.
As an example from one of the test servers at my office:

Code:

dev-test3 ~ # netstat -tulpn

Hope that helps. Let us know.

...that said one could easily read the documentation and end up with the simple 'apt-get source <packagename>;' command. Nothing to be really "astonished", "surprised" or whatever else about.

Solved the second answer!

I digit "sudo netstat -tulpn" and output me all others process pid and name
