• clear IP address of Ethernet interface

  - by jackhab

  What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong? EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man

• Why is it I can't use my Windows installation both as a host and a guest?

  - by Josef

  I have Linux installed on my harddrive, sometimes I run it as the host operating system and sometimes run it as a guest in Windows using VirtualBox. It's a nice ability, I think. I don't think it's possible with Windows though. Is it because your average distribution includes drivers for everything known to man? Are devices/drivers configured…

• What's the max Windows 7 access possible to restrict tampering with single service?

  - by Crawford Comeaux

  I'm developing an ADHD management system for myself. Without going into detail (and as silly as it may sound for a grown man to need something like this), I need to build a me-proof service to run on my Windows 7 Ultra laptop. I still need fairly complete access to the system, though. How can I set things up so that I'm unable to "easily"…

  - by Chris

  I'm seeing some errors in my apache logs and they may (or may not) be related to some packages that I recently installed/removed using Yum. Is there a way to view the history of Yum packages that have been updated/installed/removed ? I could use the "history" command from unix, but some installations may have been done with different…

• Release/Renew IP Address via Terminal in OS X

  - by Rupert

  I am looking to release and renew my IP address in OS X 10.4 using Terminal. Essentially, I need the OS X equivalent of Windows: C:\ ipconfig /release C:\ ipconfig /renew However, I need the interface to remain active during this process, so using ifconfig down/up will not work. I believe I can clear the IP with ifconfig delete…

• Setting the secure flag on cookies from Outlook Web Access

  - by Cheekysoft

  I'm running Exchange 2007 SP3 which is exposing outlook web access over only HTTPS. However the server delivers the sessionid cookie without the secure flag set. Even though I don't have port 80 open, this cookie is still vulnerable to being stolen over port 80 in the event of a man-in-the-middle attack. It also contributes to a…

• Looking for a recommendation for an OS X Bash manual

  - by Mental Sticks

  I've just begun to use the Terminal in Mac OS X and I've found the man command very useful, although very often the explanations are too compact or complicated for me. I am looking for a very basic reference guide – like O'Reilly makes, for example. But in there I didn't find an entry for basic commands like ls or ln and a…

• Testifying rasing net.core.somaxconn can make a difference

  - by petermolnar

  I got into an argument on the net.core.somaxconn parameter: I was told that it will not make any difference if we change the default 128. I believed this might be enough proof: "If the backlog argument is greater than the value in /proc/sys/net/core/somaxconn, then it is silently truncated to that value"…

  Platform: CentOS 6.2 Shell:tcsh I'm playing around with cd for a BASH script, and noticed the wondrous cd - option, but was left with many questions... Why the cd -? Isn't this redundant with cd ..? EDIT [As FatalError points out, these two commands don't do the same things... so the answer is "no"] Can…

The purpose is to run the command occasionally with other commands to keep my tools up-to-date (probably in a cron job on my development machine.

• What is archive mode in rsync?

  I know you can use -a or --archive to activate archive mode when using rsync. Unfortunately, I have no idea what archive mode is supposed to do, and the man page is not at all explicit about what this is: equals -rlptgoD (no -H,-A,-X) Wow. That reminds me of this…
