I'm the Fedora Project Leader. I work for Red Hat — and for the Fedora community at large! – but my posts here are all my own.

Previously, I was a sysadmin in the Academic Computing group at Harvard School of Engineering and Applied Sciences, and before that, I made Boston University Linux.

comment linux/solaris kill many proccess with one command
But be very careful if going between Linux and Solaris, because at least on older versions of SunOS that I used, killall literally kills all processes, without the process matching and selection of the Linux version.

comment Netcat (nc) traditional package for RHEL 6.x?
What''s wrong with "You can change the options used by configuring the PHP script", the first suggestion in the docs you've quoted, to which installing an alternate nc is given as an alternative?

comment Log ports opened by an application
What if the program happens to use something other than documented or what it claims to use? (Unlikely to be true with git, but could happen in other cases.)

comment How to list logged-in users on Scientific Linux (RHEL clone)?
I think it's probably this bug, although that's rather old — maybe the Fedora change didn't get into RHEL? (See also blogs.gnome.org/halfline/2007/06/29/login-records)

comment What is “Radan HTTP”?
This seems right, but I think it's probably not scanning software, just netstat, which reads from /etc/services, which uses names from the IANA list linked to in the question.
