Amazing VPN software for OSX

I hate most of the VPNs out there; unfortunately most of the time, each single firewall/router/whatever requires a particular client software which is of course incompatible with its cousins.

I was about to create the usual Windows virtual machine to use a new amazing VPN client required by one of my customers, then I discovered a little gem for OSX called VPN Tracker Professional.

So far I managed to connect my MacBook to more than ten different VPNs, and I can’t believe how it works well; it’s not cheap, but if you need to manage many connections be sure to check out the trial version.

Another good alternative is IPSecuritas (free); if you want to try it out alongside VPN Tracker, I advise you to unload the VPN Tracker kernel extension, as simple as:

su kextunload -b com.equinux.VPNTracker

The VPN Tracker kernel extension will be reloaded at the next program launch.

Note to self: SElinux and duplicity

A box with RHEL5 or Centos5 and SElinux enabled could make duplicity fail with this error:


ImportError: /usr/lib/python2.4/site-packages/duplicity/_librsync.so: cannot restore segment prot after reloc: Permission denied

To fix it, run the following command:


chcon -t texrel_shlib_t /usr/lib/python2.4/site-packages/duplicity/_librsync.so

Clear the OS X dns cache

Sometimes I need to to some DNS related work, and usually OS X pisses me off by seemingly keeping a cache of recently resolved names 🙂 .

To clear this cache, simply execute this command in a terminal:


lookupd -flushcache

Cocoa Remote Desktop 0.4 in beta

May 7, 2007 at 11:16 am | Posted in osx, software, sysadm | Leave a comment

One of my favourite OS X applications just got better; check out the latest release of Cocoa Remote Desktop, 0.4 beta 1.

Here’s a quick list of the most relevant changes, please refer to announcement for more details:

  • Clipboard support: text can now be copied and pasted between active sessions and OS X
  • Save screen capture to file
  • Quick connect: connect to a server by just typing the address into the toolbar and hitting enter
  • Third mouse button recognized (usually middle-click)
  • Throttled mouse events, which should speed up sessions on very slow bandwidth connections

I would happily help the author in finding bugs, but at the moment I have yet to see one 🙂 , kudos to arcadiclife.
