Tunnelblick very slow-makes entire client slow #135

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Tunnelblick w/Tiger on Intel Laptop (older one) connected to Windows Server 
2003 running 
OpenVPN
2. Connection much slower than PCs running OpenVPN using similar config files
3. Watching log,  it seems like Tunnelblick continuously resets including entry 
of SE_Reset - can 
hear fan come on in laptop even if no other apps are running and things get 
pokey.  Don't 
actually lose connection, just very pokey doing anything on server or client 
once VPN is 
connected

We are basically using the same config files we use on the PC side - is that a 
mistake?

What is the expected output? What do you see instead?
I expect (want) the connection to be fast like it is with PC's we are using.  
Apologize if this has 
been addressed and I'm missing it - figure this may be an issue with our config 
files?  

What version of Tunnelblick are you using? On what version of OS X? PPC or 
Intel?
Tunnelblick 3.0b24 build 1301 (OpenVPN 2(2,1 rc20)
Tiger on Intel Mac laptop (2GHz Intel Core Duo, 2 GB RAM)

Please provide any additional information below.
Here is a portion of the log file and client config:

Config File

##############################################

I should have mentioned (soholistic again) that I am using Remote Desktop to 
connect to the server through the 
tunnel.

A Google search of "SE_RESET openvpn" yields a thread on the Viscosity forum 
(Viscosity is another OpenVPN 
GUI): http://www.viscosityvpn.com/forum/viewtopic.php?f=3&t=25

I don't see anything wrong with either your config or the one in the forum, but 
the following three lines are 
not ones that I use, and appear in both configs, so maybe they have something 
to do with it:

nobind
persist-key
persist-tun

or maybe it just has something to do with the file format of the config file or 
something -- he/she seemed to 
fix his/her config file by replacing it with an OpenVPN sample config file 
(edited to match his settings, I 
assume).

Thanks - will try what you suggest.  In fact, config was brought over from 
windows machine and maybe text 
version is the problem.  Thanks again!

If you start Tunnelblick with no configuration file present in 
~/Library/Application 
Support/Tunnelblick/Configurations, Tunnelblick will create a sample config 
file for you and open it in TextEdit. 
You could then copy/paste from your PC config file.

Please let us know what happens.

Just found a bug in what I just suggested - after it creates the sample config 
file, Tunnelblick opens the wrong 
copy TextEdit. Just exit TextEdit and open the file by double-clicking it in 
Finder.

Bug referred to in my comment 5 was fixed in the source in r324.

Tried contacting the original poster directly to find out if this has been 
resolved. No response for three weeks.
