vsftpd saying 500 OOPS: priv_sock_get_cmd (after update?..) (Page 1) / Networking, Server, and Protection / Arch Linux Forums
There is an obscure, non selinux, problem with Fedora vsftpd when running on a VM.
Below is a one line fix that will save you lots of debug time :)
The log file will report various selinux failures, but that is NOT the problem. The ftp sessions will get a few error messages, and be dropped from the server.
It occurs when running Fedora in a VM.
yum -y install vsftpd
vi /etc/vsftpd/vsftpd.conf
# Workaround for 500 OOPS: priv_sock_get_cmd

HowTo: Restore an Ubuntu system with a bad kernel, broken network driver, unbootable system.
http://askubuntu.com/questions/28099/how-to-restore-a-system-after-accidentally-removing-all-kernels
When you lose a network driver, or have a bad kernel for some reason, this will get you going.
You are starting a working system, then setting up the essentials to chroot into your broken system. The kernel, drivers and things you need are borrowed from the working system. Then you can reinstall packages, until it's working again.
First boot from a Live Ubuntu DVD/USB. Select Try without installing. Open a terminal, and follow the instructions in the Link. Your mileage may vary, I'll try an example with sda1 boot, and sda2 root filesystem.
# Mount the root filesystem to /mnt
mount /dev/sda2 /mnt
# Check /mnt for a root filesystem (bin var etc ...)
ls /mnt
# Mount the boot partition to /mnt/boot
mount /dev/sda1 /mnt/boot
# Check /mnt/boot for kernels, if not, figure out where they are.
ls /mnt/boot
# Mount the system partitions from the Host OS.
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
mount --bind /dev /mnt/dev
# Chroot to your linux where everything works now...
chroot /mnt
# now you at / in your old linux.
# set the environment
mount -t devpts none /dev/pts
export HOME=/root
export LC_ALL=C
# Verify you have a working network
nslookup google.com
ping google.com
At this point you can apt-get packages and fix your system.
--- after chroot
# See what kernels you already have.
ls /boot
# See what kernels you might want.
apt-cache search linux-image
# Depending on space in /boot, install an old and new one you might like
# An old generic one in the preempt list might not appear in the regular list
apt-get install linux-image-<2 .6.32-36=".6.32-36">-generic
You can fix about anything wrong with a bad system with this!

HowTo: Git Branch Merge with Rebasing
Rebasing Merge Commits in Git | Envato Notes
Thousands of files in a git merge...Hundreds of merge conflicts...Someone will commit before you are done...so just assume...
You will have to rebase the merge before you push it to the remote.
The obvious way, git pull --rebase, not so good...you lose your merge and start over.
This describes a Branch Merge, (merging two branches in a single git clone). Android Repo doesn't do multiple branches - I tried to find an easier way...
1) Install one of the git supported merge tools.
If the merge tool is on the path, git mergetool will automatically call it for each of your merge conflicts - very fast.
merge tool candidates: meld opendiff kdiff3 tkdiff xxdiff tortoisemerge gvimdiff diffuse ecmerge p4merge araxis bc3 emerge vimdiff
(I like meld on Linux, it works with cvs, svn, and git.)
2) Branch Merge: Merge all changes from two branches so that they match in content and point in time.
# Clone the repo containing the branches you want to merge.
git clone xxx
# Get the branch_to_merge
git checkout branch_to_merge
# Bring changes from Master to branch_to_merge.
git merge master
# Resolve any conflicts
git mergetool
# Switch back to branch master
git checkout master
# Bring changes from branch_to_merge to master
git merge branch_to_merge
# Resolve conflicts
git mergetool
# See if there are any differences between the merged branches.
git diff branch_to_merge..master
# Done, start testing...
3) Get any changes since you started merging.
# Before push, get any changes.
git checkout master
# Get new commits from the remote.
git fetch
# Move your merge "aHEAD" of the new commits.
git rebase --preserve-merges origin/master
# You may have a set of conflicts to resolve.
git mergetool
# If there are conflicts, you will be on a detached head. Must continue.
git rebase --continue
# Save the commit message when it comes up.
# At the end of rebase you will be back on master branch.
# Next get these changes to the other branch being merged.
git checkout branch_to_merge
# Get any new commits from the remote branch_to_merge.
git fetch
git rebase --preserve-merges origin/branch_to_merge
git mergetool
git rebase --continue # Upon resolving the conflicts, you will see the commit message again.
# Save it, and you are (almost) done.
# If there were commits on the branch_to_merge,
# switch back to master and merge them in (checkout, merge, mergetool).
# You are at a stable point for pushing your merge again...
# Both local branches should match, no differences.
git diff branch_to_merge..master
# Both branches should match in time.
# You should see your final merge first, at the HEAD of the tree.
git checkout master
git log --oneline --graph
git checkout branch_to_merge

HowTo: Fix Gerrit 'Failure to submit due to path conflict'
Failure to submit due to path conflict but no real conflict. - Google Groups
Git Tools - Stashing
While there's a lot of discussion, there's no real howto to fix things up using repo using three simple commands.
Gerrit won't merge when someone is too slow to merge your changes, you've ameded your merge...A change came in before your change was merged...it happens...a lot.
repo start [branchname]
# You've made your changes and sent them to Gerrit...
repo upload
Gerrit merge fails. Here's HowTo fix it.
# Get on your repo start [branchname]
git checkout [branchname]
# Find the name of the remotebranch you are merging to with Gerrit.
git remote
[remotebranch]
# Your local changes need to be stashed for now.
git stash
# Fix your branch so you can merge with Gerrit.
git rebase[remotebranch]/master
git stash apply
# Amend the commit on your fixed branch.
git add .
git commit --amend
# After upload, you should see a new patch to your merge in Gerrit.
repo upload
# Get rid of stashed changes that have been merged
git stash clear
At this point, you should be able to review and merge in Gerrit, hurry up :)

HowTo: Fix Vi Backspace and delete problems
Backspace and delete problems - Vim Tips Wiki
Coming into a Suse system, vi didn't do colors, and the backspace key wasn't working...Here are three obscure things found when logging into lots of different systems.
Add these lines to your ~/.vimrc file.
NOTE: Use the real backspace key for ^?
You may also need to fix the backspace key in the terminal. Put something like this in your .profile, .bashrc, whichever works.
Some systems don't add a .profile to your user account. No problem until you log in remotely (i.e. ssh), then you get a warning, can't find your profile, screen doesn't look right...

HowTo: search for files excluding binary files on Linux
search for files excluding binary files - The UNIX and Linux Forums
An old problem with CVS is that you need to identify the binary files as you add them in (cvs add -kb). Otherwise, the next version will do an ASCII merge, trash the previous version, and you won't know until you try to restore an old version. Mostly happens when moving between Linux and Windows. Thanks to zazzybob, this will find ASCII files really well, and save me a bunch of work.
find . -type f -print | xargs file | grep "ASCII\|HTML\|text\|XML" | cut -d: -f1
Finds all binary files (almost) but very close...With the CVS problem, 'cvs add' the known good ASCII files, and any that are missed won't be re-added...
find . -type f -print | xargs file | grep -v "ASCII\|HTML\|text\|XML" | cut -d: -f1

echo "ERROR: $(HEADER_FILES)"
else
# File exists, continue or do something else...

HowTo: Install GNOME 3 Shell Extensions
Five must have Gnome shell extensions for Fedora 15 « Justin Stories
Earlier, I've blogged on the difficult to install weather extension (Rick Foos HowTo Blog: Gnome Shell Weather Extension ~ Web ...).
So how do you install GNOME 3 Shell Extensions?
First, Remember - Must Reset Desktop when Changing Shell Extensions
Alt-[F2], r
...Ubuntu is mostly the same with apt-get instead of yum...After you install the extensions, exactly the same...
# Install GUI to manage shell extensions.
yum -y install gnome-tweak-tool
# What are the available shell extensions?
yum list gnome-shell-extension-*
A list follows with some possibilities...
yum install gnome-shell-extension-*
# Enable/Disable Shell Extensions from a gui.
gnome-tweak-tool
While many of them may not do what you expect, some are good.
Some extensions will need settings to be customized.
# Find where the settings for a shell extension are located.
# NOTE: Extensions may or may not have 'extension' in their schema name.
gsettings list-schemas
# Find the current settings, for an extension.
# if you have a keyword to grep, you can use that or copy one of the schemas from the list.

Earlier, I've blogged on the difficult to install weather extension (Rick Foos HowTo Blog: Gnome Shell Weather Extension ~ Web ...).
So how do you install GNOME 3 Shell Extensions?
First, Remember - Must Reset Desktop when Changing Shell Extensions
Alt-[F2], r
...Ubuntu is mostly the same with apt-get instead of yum...After you install the extensions, exactly the same...
# Install GUI to manage shell extensions.
yum -y install gnome-tweak-tool
# What are the available shell extensions?
yum list gnome-shell-extension-*
A list follows with some possibilities...

While many of them may not do what you expect, some are good.
Some extensions will need settings to be customized.
# Find where the settings for a shell extension are located.
# NOTE: Extensions may or may not have 'extension' in their schema name.
gsettings list-schemas
# Find the current settings, for an extension.
# if you have a keyword to grep, you can use that or copy one of the schemas from the list.
