This too shall pass.
During some recent server patches on Red Hat Enterprise Linux 5.3, I kept getting ‘depsolve’ errors on several packages. This was odd, as I had not made any changes to anything, installed anything new, or removed anything.
Turns out this is a known bug in 5.3, and luckily, the solution is simple:
$> yum clean all
Run that, and it refreshes your local repository. The next time you go to update packages your server will refresh everything with the Red Hat respository, and all will be good!
Have you ever been in a rush or just had a complete brain freeze with your MySQL passwords?
Well…..I have. 🙂
——————————-
Step # 1 : Stop mysql service
SHELL> /etc/init.d/mysql stop
——————————-
Step # 2: Start to MySQL server w/o password:
SHELL> mysqld_safe --skip-grant-tables &
——————————-
Step # 3: Connect to mysql server using mysql client and setup the new root password:
SHELL> mysql -u rootmysql> use mysql;mysql> update user set password=PASSWORD("$PASSWORD") where User='root';mysql> flush privileges;mysql> quit
——————————-
Step #4: Stop and Restart MySQL Server: (try your new $PASSWORD)
SHELL> /etc/init.d/mysql stopSHELL> /etc/init.d/mysql startSHELL> mysql -u root -p

Note: There are other ways to reset the password, but I like this one.
I was poking through my blog posts from 5 years ago and found one referring to GMail invitations. I had forgotten that GMail was by invitation only for the first few months of its existence.
Those were the days!
Over the past few years several people on the VMware communities forums have released patches to fix the vmware modules for the next “fresh” release of the Linux Kernel / Distro. I’ve used them in the past with much success, but I generally like waiting for the official VMware support. However, I’m pretty excited about Fedora 11 (just to many new goodies not to play) and I noticed there’s a new updated patch for 2.6.29 and even 2.6.30 Kernels!
VMware Workstation 6.5.2 module patches/discussion: 2.6.29
VMware Workstation 6.5.2 module patches/discussion: 2.6.30
Sun has official Fedora 11 support (and now 2.6.31) with VirtualBox: VirtualBox 3.0.0 (if that’s your cup of tea)
Note: Obviously Fedora is the test bed for the QEMU/KVM merger so you can go that route as well, but I love VMware. ;0)

Starting in Fedora 10 (but disabled by default) Red Hat Fedora started providing the KMS Framework.

X.Org – KMS page : Click Me
Now if you’ve upgraded/installed the new Fedora 11 (or even Ubuntu 9.x etc.) KMS is enabled by default and you may have noticed there are new/still some regressions in the kernel and certain Intel and ATI cards may have issues.
If you’re having some crazy issues, fear not, you may have an answer here.

Ati/AMD Video Issues: Click Me
Note: This isn’t Fedora specific, you may have noticed you cant even enable desktop effects in Ubuntu 9.0.4 under certain cards (without de-blacklisting)
This is just the natural progression of trying to make things better and part of the growing pains that going with non-enterprise distros of Linux can give it’s users……but end the end, it will be worth it.
HTH.
If you are a conscientious system administrator, you like to keep tabs on your server by checking root’s email at least once a day, correct? If you manage more than one server, or get tired of having to log in to check your mail, you can redirect where email for the root user gets sent.
I ran into problems on Red Hat Enterprise 5.2 doing this, so I thought I’d post the resolution here.
I wrote previously about Facebook hacking, which is something everyone needs to be aware of, but there is a more immediate Facebook danger which millions of people every day are already exploited by. Not only could it lead to insecurity, but your personal data is being exposed to advertisers every time you take one of those “What kind of hamburger are you” quizzes.
Facebook applications get access to all data of users who sign up, though users sign up for dozens of one-time use applications like these quizzes without thinking twice. There are hundreds of applications springing up every day, and Facebook’s model of implementing no technical sandboxing and policing applications when things go wrong is completely unscalable.
This applies to RedHat Enterprise 4 & 5, and by association to Fedora and CentOS. It probably works on some other distros as well, but your mileage may vary.
I am constantly having to reset user passwords, as I use the “three failures and your account is locked” schema, as well as set passwords to expire every 60 days. Continue reading “User Management: Passwords”
I guess that stock photography libraries just don’t have that many images of blind guys sitting at a computer with a cane. Why not just whip out Photoshop and add your own glasses and cane? I mean — it’s software for blind people, so no one will notice, right?
