No MySQL password in ps aux!
by Dotan Cohen 14 Sep '11

14 Sep '11

I just noticed that some CentOS 4 or 5 machine that I don't admin but have root access to hides MySQL passwords from ps: Console 1: $ mysql -u root -pSECRET mysql > Console2: # ps aux root 32165 0.0 0.1 109408 2204 pts/1 Ss+ 11:19 0:00 mysql -u root -px xxxxxxxxxxxxxxxxxx That is really nice, is it a MySQL feature or a CentOS feature? I have some other servers that I _do_ admin and I'd like to enable this. Thanks! -- Dotan Cohen http://gibberish.co.il http://what-is-what.com

Recently hacked sites..: http://www.linuxfoundation.org/ http://www.utorrent.com/ http://kernel.org/ http://www.linux.com/ Has the CentOS site ever been hacked? Are there any good audit processes to check the servers? CentOS team, please be aware, there are many script-kiddies OR pro's out there who want websites like yours! I love CentOS, and I don't want it to fail like kernel.org: http://blackhats.com/infosuck/0x007c.png Please pay more attention than in normal case! :\ /just an anxious CentOS user/ Thanks and sry for this e-mail.

CentOS 6: "ip link" ignores wlan0
by Michael D. Berger 14 Sep '11

14 Sep '11

On my CentOS 6 laptop, in which the wireless hardware is known to be functional (because it works in the WinXP partition): # ip link shows lo and eth0, but nothing else. Why might this be? Thanks, Mike.

Vitualization and Partitioning
by Thomas Dukes 13 Sep '11

13 Sep '11

Hello, OK, getting ready to order a new machine and had some questions about 6.0. It will have a single 500GB HD. When I do the install, do I or should I setup a separate partition for guest OS's? From the redhat docs, it looks like the guest OS's reside at /var/lib/libvirt/images/. I may combine my windoze XP on the CentOS machine so would I need to create a partition and format that at installation? If I decide to wait and go with Windoze 7 can I still create the partition later? I would like a partition scheme that allows for easier upgrades or installs without losing data. Thanks, I'm more confused now that when I started reading about this stuf.. Eddie

Cannot mount NTFS filesystems under Xfce4
by Keith Roberts 13 Sep '11

13 Sep '11

I have installed the following 2 packages on Centos 5.6, and used GParted to successfully create an 8GB NTFS partition, on some unused HDD space. Installed Packages Name : ntfsprogs Arch : i386 Version : 1.13.1 Release : 6.el5 Size : 1.1 M Repo : installed Summary : NTFS filesystem libraries and utilities URL : http://www.linux-ntfs.org/ Name : ntfsprogs-gnomevfs Arch : i386 Version : 1.13.1 Release : 6.el5 Size : 20 k Repo : installed Summary : NTFS GNOME virtual filesystem module URL : http://www.linux-ntfs.org/ I'm running Xfce 4, and when I try to mount the NTFS file system, I get an error box with 'ntfs - unknown filetype' I've done a complete reboot of this box. Are there some packages I have missing?
