Repeated disconnection/reconnection attempts on Mountain Lion #206

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
On OS X 10.8.1 or 10.8.2 ("Mountain Lion") some configurations that use "Set 
nameserver" causes Tunnelblick to continuously disconnect and reconnect the 
configuration.

The disconnect/reconnect will appear in the log as something similar to:

2012-03-26 22:17:33 *Tunnelblick process-network-changes: SearchDomains changed 
from
                    *                    
                    *                     to
                    *                    <array> {
                    *                    0 : openvpn
                    *                    }
                    *                    pre-VPN was
                    *                    

To work around this problem while still using "Set nameserver", you can do the 
following:

Click the "Advanced" button on the "Settings" tab for the configuration, then 
select the "While Connected" tab. Change the setting for "Search domain" in the 
right-hand column (the "When changes to anything else" column) from "Restart 
connection" to "Ignore". That will ignore the changes to "Search domain".

Anyone with a similar problem on Mountain Lion but not involving 
"SearchDomains", please post the extract from the log that is similar to the 
above extract, including the name of the item that changed.

Same "SearchDomain" issue for me on 10.7.3 and Tunnelblick 3.2.3 (build 
2891.2932) Unsigned  -  OpenVPN 2.2.1.

OS X 10.7.3 Tunnelblick 3.2.3 or 3.2.4 keeps reconnect even with disabled 
"Monitor network settings" flag and restart. Is there any other known 
workaround to make it work?

3.3beta04 the same issue.

I have the same problem on Mountain Lion with the stable version of Tunnelblick.
It's the same with Viscosity. BUT, in the new beta of Viscosity 
(http://www.thesparklabs.com/forum/viewtopic.php?f=7&t=34#p134) it's fixed! So 
if anyone wants OpenVPN to work on Mountain Lion I can recommend the new beta 
of Viscosity meanwhile.

@nygganh --

The workaround doesn't work for you? If not, it is a different problem (with 
the same symptom) and will probably have a different solution. I would 
encourage you to post the complete Tunnelblick log and your configuration file 
to help solve your problem using Tunnelblick.

@Sergei --

You are also having a different problem with the same symptom. Please post the 
complete Tunnelblick log and your configuration file.

I have similar problem. But I fixed it by set DNS to "Set nameserver (3.1)".

I have similar problem. Setting 'Search domains' to 'Ignore' in the 'While 
Connected' tab prevents disconnects. However OS X Mountain Lion DP 4 looses 
Internet connection entirely. Everything worked fine in OS X Lion.

GoogleCodeExporter commented 9 years ago 
To add a note, by implementing the workaround (either setting name servers to 
ignore or using 3.1 as descibed above) I lost all DNS connectivity.  Only after 
manually adding DNS's to the OS X Network settings (I used Google's 8.8.8.8 and 
8.8.4.4) did things start to work again.

GoogleCodeExporter commented 9 years ago 
yes, I have the same problem.  Once I set Advanced->Monitor Network settings-> 
Search Domain in right column to Ignore, it no longer disconnects but I lose 
all network connectivity. I had set the DNS server manually to get accesss to 
the Internet and use IP addresses of the company build servers to ssh into 
them. DNS is no workee!!!! I updated to OSX mountain lion yesterday. Someone 
please escalate a fix for this issue as it will affect a lot of people when the 
mountain lion comes up in one week.

It would help fix the problem faster if people would post their configuration 
files and logs (preferably both from Lion and from Mountain Lion using the same 
configuration file):

To get the Tunnelblick log on the Clipboard so you can paste it into an email:
1. Click the Tunnelblick icon
2. Click "VPN Details…"
3. Select the "Configurations" panel if it is not already selected
4. Select the configuration whose file you want to look at in the list on the 
left
5. Select the "Log" tab if it is not already selected
6. Click "Copy Log to Clipboard"

To put the contents of your configuration file on the Clipboard so you can 
paste it into an email, open it in TextEdit as follows:
1. Click the Tunnelblick icon
2. Click "VPN Details…"
3. Select the "Configurations" panel if it is not already selected
4. Select the configuration whose file you want to look at in the list on the 
left
5. Click the little "gear" icon at the bottom of the list on the left
6. Select "Edit OpenVPN Configuration File…" (or possibly "Examine OpenVPN 
Configuration File…").
7. In TextEdit you can Edit : Select All and then Edit : Copy to get the 
contents of the configuration file put into the clipboard.

 @ani - Thanks. Two things:

(1) If you are using your IPS's DNS servers (for example, from home) and you 
connect to a VPN, all your DNS queries will go through the VPN, and appear to 
the ISP's DNS servers to be from outside their network. Many ISPs ignore such 
requests, with the result that you appear to have lost all connectivity (but 
pings would still work). In that case, since your VPN server isn't "pushing" 
its own DNS servers to you, you will need to set DNS servers manually in your 
System Preferences Network panel. You can, for example, use Google's public DNS 
servers at 8.8.8.8 and 8.8.4.4, or use OpenDNS's, or whatever else you want.

(2) That said, it also looks possible that Tunnelblick's 
"client.up.tunnelblick.sh" script is crashing. Can you check your console log 
for any relevant messages? Thanks.

I am pretty sure it used to. I never had to add DNS servers manually in
Lion.

When DNS stopped working, I had to add them manually. I now manually added
Google's DNS servers and our internal DNS server IPs.

Nop! nothing in console log yet!

I resolved this issue by adding the following on server side and without 
modifying tunnelblick config (as people suggested):

push dhcp-option DOMAIN example.com

and then restart openvpn server

Now I can see that the correct DNS and domain are pushed, but it only does IP 
resolution and not NAME resolution. For example, on terminal I can do "host 
foo.example.com" and it shows the correct IP, and in Chrome/Safari I can go to 
the site by entering the IP of foo.example.com but if I enter foo.example.com 
in URL it does not resolve! I get the following error:

Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS 
address.

I am using Mountain Lion GM and the same configuration used to work on Lion and 
they are currently working on Ubuntu and Windows (by other dev users for the 
company). I have tried with Tunnelblick 3.2.6 stable. Does anyone have any 
solutions?

Ah. Different version of Tunnelblick, too.

Can you get the log for 3.3beta06 on Lion? (You can just download the .dmg
and drag the Tunnelblick icon to the Desktop and run it from there; that
way you leave your existing 3.2.5 in /Applications uchanged.)

Thanks, ani.

The only thing that seem different about 10.8 is that it has trouble
connecting to the VPN server the first time:

2012-07-11 14:33:31 TCP: connect to [AF_INET]4.53.128.220:1194 failed, will

which seems odd, but doesn't really seem relevant to the problem.

I am also puzzled as to why client.up.tunnelblick.sh didn't output any
messages, but since it didn't output any in either log, nor did anything
show up the Console log, I don't know what that means.

So it looks like it may be something in OpenVPN, or possibly Tuntap.

Let me make sure I understand the problem (on 10.8):

   - The VPN connects and stays connected (after setting Advanced->Monitor
   Network settings-> Search Domain in right column to Ignore)
   - You can't browse to anything, either by name (www.google.com) or by IP
   address (173.194.75.104)
   - Nothing shows up in the Console log.

Also, did you try OpenVPN 2.2.1 when on 10.8? (It's on the "Preference" tab
of the "VPN Details…" window.)

Thanks for all your help with this.

BTW, can you dual boot (10.7 and 10.8) or did you just revert to 10.7 on
your (single) setup?

On your three points regarding 10.8 :
-yes, it does stay connected after that settings change.
- no, I can still browse using IP or if I set my /etc/hosts to resolve the 
names to IPs. So it seems the issue is DNS specific.
- yes, no crash logs on the console log.

Unfortunately I only have my work mac and I have restored it to 10.7.4 from my 
time machine. Don't want to much around with my work mac anymore.

Is there a way to verify from TunnelBlick logs that the vpn server is pushing 
the DNS server IPs to the client? In the network settings, I do see that the 
corporate DNS server IPS are populated but in Mountain Lion they were not.

Original comment by a...@arista.com on 12 Jul 2012 at 7:09

I assume you are talking about when the VPN is connected. If so, it looks
like that's the problem.

I see nothing in either the 10.7 or 10.8 logs that shows *anything* being
pushed.

Usually there would be a pair of log entries similar to the following:

2012-07-12 15:14:41 SENT CONTROL [*server-name*]: 'PUSH_REQUEST' (status=1)

 I have no idea why 10.7 is setting the DNS servers and 10.8 isn't. It
could be that the network settings in 10.7 had the corporate DNS servers
set manually -- I would expect the corporate DHCP to treat 10.7 and 10.8
the same.

I wonder if it could have anything to do with IPv6? Does your Corporate
network use it at all? Maybe that's changed in 10.8.

I have the exact same problem as above only on OS X 10.8 - I have tried with 
both the beta and the stable versions and can not replicate the problem in OS X 
10.7.  I am not connecting to a corporate VPN.  Setting 8.8.8.8 and 8.8.4.4 
allows me to browse the internet as normal on OS X 10.8 while connected through 
Tunnelblick.

martin, thanks for your report. Does anything show up in the Console
log<http://code.google.com/p/tunnelblick/wiki/cConsoleLog>?
I'm particularly looking for anything from the program "
client.up.tunnelblick.sh".

Also, please post your configuration file and log on 10.7 and 10.8 if
possible. Do you know if your VPN server should be "pushing" anything to
the client?

May be there is a verbose mode that spits out more information?

Original comment by a...@arista.com on 12 Jul 2012 at 8:58

GoogleCodeExporter commented 9 years ago 
The default is "verb 3", which should log enough to see what is happening.
What's odd is that even though it is apparently at verb 3, it isn't showing
any "push" request or any "push" info coming back from the server.

Adding "verb 4" to the client's configuration file will log more, so it's
worth a try.

Can't paste all the log without auditing - it might contain some sensitive 
information. I think it's worthwhile to try the same with verb 4 on mountain 
Lion and see what we get. Unfortunately, I am back on Lion.

Thanks. Don't need the rest of the log (although a 10.8 log might help).
Maybe your VPN server sends a "verb 2" or something, and that's why you
didn't get it before. Maybe even if you did "verb 3" it would show up.

The other thing you should see in the log is something like

and

If your co-worker still has Mountain Lion, maybe they could see if their
log contains something similar. Or if their Console log has anything.

And when they check the Console log they should check "All Messages".

I just tried my test setups on Mountain Lion and they worked fine, so it
must have to do with some particular OpenVPN option that's being used.

I followed the instructions to ignore the changes to "Search domain". Now it 
doesn't disconnect and reconnect, but as ani pointed out DNS isn't working. But 
I had some interesting findings. The file /etc/resolv.conf is correctly 
populated, and nslookup works fine. Other programs presumably don't get DNS 
servers from that file so are not working. When I looked at the DNS servers in 
the Systems Settings program, the servers were listed but in grey color. As 
soon as I clicked the + button, the servers disappeared and I had to add them 
back manually. After I added them back everything was working fine.

Below is the log after I ignored the changes to "Search Domain":

yes, I reinstalled Mountain lion gold master on a different mac and I get the 
same DNS push messages in the log. In the network advanced settings, I see the 
DNS servers populated. Yet DNS does not seem to work. I have to manually add 
google's DNS servers to browse the internet. Local company servers can't be 
reached through their names. Only through IPs.

yes, /etc/resolv.conf is correctly populated with the DNS server IPs. So I did 
a tcpdump and I see lots of bad checksums on outgoing DNS queries :

any updates on this?

No, when there's news I'll post it here.

I thought the DNS problems may be related to specific options in the
configuration file or pushed from the server. But the bad checksums points
to OpenVPN or the tun/tap kexts.

Has everyone tried using OpenVPN 2.2.1? (It's on the Preferences panel of
the VPN Details… window.)

does the tun/tap kos maintained by Apple or buy tunnelblick?

Neither one. It is maintained by the TunTap
Project<http://tuntaposx.sourceforge.net/>
.

Seems like tun/tap project does not even have a supported download for Lion!

One another update. I am observing the same issue with viscocity as well. This 
confirms that this issue is not related to TunnelBlick alone. What is a good 
forum to discuss this problem?

Tunnelblick uses the 2011-11-01 version, but creates a custom build for
PPC/Intel with 32/64-bit kernels. That build works on Lion without any
problem.

The major change from Snow Leopard to Lion was that the 64-bit kernel
became the default on most Macs. So the 64-bit Tuntap for Snow Leopard
works in Lion.

Sorry, spoke too soon. Viscocity has a beta version for Mountain Lion (1.4b11 
released 14 July 2012) that works perfectly for Mountain Lion.

So what broke between Lion and Mountain Lion?

An observation: I noticed the traffic towards the DNS server doesn't look like 
it's going through the tunnel, even though the routing table tells it to. This 
only applies when using ping/telnet etc., not dig.

now that mountain lion has been released officially, lot more people will start 
to see this issue.

I can confirm that when I chose "Set Nameserver (3.0b10)" from vpn details 
menu, my DNS is working.  My tunnelblick version is Tunnelblick 3.3beta10 
(build 3048)

Same issue here :/

I can also confirm that it is working after I chose and applied "Set Nameserver 
(3.0b10)" via the VPN details menu. DNS seems to resolve just fine now.
Running Tunnelblick 3.2.5 (build 2891.3004)  -  OpenVPN 2.2.1

This was working fine under Lion, just upgraded to ML and now it 
connects/disconnects.
