OS X ethernet self-assigned ip

Recently I had a problem with my mac, my wifi connection was working properly but my ethernet connection was not it was getting a self-assigned IP. After checking the obvious culprits (cable, router, switch) it turns out that the problem was elsewhere.

After searching the internet I realized that I wasn't the only one having this problem, and there are a lot of fixes such as :

  • Deleting the "/Machintosh HD/Library/Preferences/com.apple.alf.plist" and rebooting
  • Resetting the PRAM
  • Recreating a network configuration

By chance I decided to try and disable IPv6 on the network interfaces like so :

networksetup -setv6off Wi-Fi
networksetup -setv6off Ethernet

And after rebooting it worked !!

So there you go; I hope this works for you too!!

On a final note: Another thing I was about to try was uninstalling the virtual interfaces of my VMWARE but it didn't get to that

Git svn clear stored credentials

Recently a change was made in my company in the way the SVN repositories were handled; as a result we had to change the accounts we used to access the repos

Whenever I tried pulling or pushing info into those repositories I was getting errors like :


RA layer request failed: PROPFIND request failed on '/svn/2001/ufasoli/myproject/trunk': PROPFIND of '/svn/2001/ufasoli/myproject/trunk'
: 403 Forbidden (https://internal.svn.com) at /lib/Git/SVN.pm line 717

I realized that it was because the credential information was cached locally on the machine, so the system was sending old information , the tricky part was that the old accounts allowed authentication on the repositories, they were just no longer authorized to do anything on them, so I was getting an HTTP 403 error and the system was not prompting me for a new password (since the old accounts could still log in...)

So this is how I fixed it on my windows machine:

Under your user folder you should have a folder where subversion stores cached data C:\Users\ulf\.subversion (in my case)

This folder contains an auth folder were you will normally find another 3 folders :

  • svn.simple
  • svn.ssl.server
  • svn.username

To delete the cached credentials you can delete the content of the following folders :

  • svn.simple
  • svn.ssl.server

Once this folders deleted git should prompt you again for your username/password

OSX paste unformatted text / remove text formatting

So recently I found about what is for me one of the best keyboard shortcuts on OSX often I copy text from somewhere and whenever I paste it...
