Yosemite 10.10.1 - ssh - no connection (time-out) and strange redirect I hope I can get some help with a rather strange problem on my late 2013 MacBookPro running Yosemite 10.10.1

Up until 3 days ago, I could ssh into my server without any problems. I then updated to 10.10.1 and started to see some strange behaviour. At first I didn't notice, but it turns out I can not connect to remote ssh-boxes anymore. Local connections (including those via open-vpn tun-interface to a remote host) seem to work fine though.

Looking at a TCP dump when trying to connect to a box via internet revealed the following strange fact:

my.internal.ip.address.50596 &gt; gl02.opentracker.net.ssh: Flags [S], cksum 0x7b7d (correct), seq 4179750266, win 65535, options [mss 1460,nop,wscale 5,nop,nop,TS val 958226379 ecr 0,sackOK,eol], length 0


Doing the same one an up-to-date Mavericks box shows no signs of "gl02.opentracker.net" address and everything works just as it should be.

Since I cannot find a way to prevent (or even change/turn off) this "feature" on my MacBookPro, I consider this to be HARMFUL and an unwanted intrusion / exploitation (go take a look at ww.opentracker.net - I do NOT want to be anal-yzed by those guys!!!).

So here are my questions:


Why is my Mac trying to connect to "gl02.opentracker.net"?
Where does this behavior come from?
How can I turn this off?
Is this a malicious attempt to break my security? (--> thinking "Root-Pipe" exploit I heard about)
If so, where do I find people with proper digital-forensics knowledge and further information about this subject?


If you need more information regarding the configuration of my machine, please tell me which commands to run / config-files to provide to help track down this issue.

Thanks.
opentracker.net is a service provider that offers analytics. My guess is that your redirection happens when you are connected to a network provider that internally uses opentracker.net.

I suggest you try again from another network provider.
