From the mind of Emil Soleyman-Zomalan

I will be updating this entry with commands that I have come to use throughout my system administration and engineering work. I hope that it is of some use to readers who stumble on this site. 

1. Watch for changes in active and inactive connections in the Linux Virtual Server kernel table
   watch -n 5 "ipvsadm -L -n"
   
2. List the types and amount of TCP states in the linux networking subsytem
   netstat -tan |awk '{print $6}'|perl -ne 'chomp; $a{$_}++; END { print map({ "$_:$a{$_}\n" } sort keys %a); }'
   
3. List the SYN_RECV state per IP address
   netstat -tan |grep SYN_RECV |awk -F '[ :][ :]*' '{print $6}' | perl -ne 'chomp; $a{$_}++; END { print map({ "$_: $a{$_}\n" } sort key
   s %a); }'
   
   
4. CHMOD all of the files (not directories) in a directory
   find . -type f -exec chmod a+r \{\} \;
   
5. CHMOD all of the directories (not files) in a directory
   find . -type d -exec chmod a+rx \{\} \;
   
6. Find the largest file in the filesystem excluding NFS mounted shares
   find / -fstype nfs -o -type f -ls | sort +6n -r | less
   
   
7. Find the largest files in the filesystem
   find / -xdev -type f -ls | sort +6n -r | less
   
8. Remove the CVS directories that populate a source directory
   find ./ -name CVS -type d -exec rm -fr {} \; -- find ./ -name .cvsignore -exec rm -f {} \;

I'm beginning my work on Bug 363609 for gnome-terminal. Read the bug report for more information.

I'll post my findings to this entry ...

UPDATE: I'm back working on this issue. I am tracking down the last few code paths that will lead to crashes. I hope to have some time to fix those.
