[Solved]gave up trying to fetch IP address information

Post by mcsass » Fri Jan 02, 2015 4:46 am

Happy New Year!

Can anyone help me with my configuration?

I am running OS X 10.8.5, trying to use Tunnelblick 3.4.2 to connect to my Netgear R7000 running DD-WRT.

After some trouble shooting and Googleing, I have decided to see if anyone else can help me with my latest issue.

The error I am getting is:

Code: Select all

2015-01-01 20:05:44 *Tunnelblick: After 30.0 seconds, gave up trying to fetch IP address information using the ipInfo host's name after connecting.
2015-01-01 20:06:14 *Tunnelblick: After 30.0 seconds, gave up trying to fetch IP address information using the ipInfo host's IP address after connecting.
Any help would be greatly appreciated!

I am getting the same error as well. Everything was working until a week ago, and I started getting this error on the client with no changes on the server or client. I have been trying to debug this the last 2 days, but no luck yet.

Client log -
Tunnelblick: After 30.0 seconds, gave up trying to fetch IP address information using the ipInfo host's name after connecting
Client popup -
After connecting to xxx, the Internet does not appear to be reachable. This may mean that your VPN is not configured correctly
I was at TunnelBlick 3.4.x, and now upgraded to 3.5.beta04. Get the same error. Here is the client configuration -

can you post the output of:

Michael,

Yes, we want the packets routed via VPN. The DNS resolves both on the client and the server.

Code: Select all

Mac Client

$ nslookup www.example.com.
Server:		8.8.8.8

Non-authoritative answer:

$ ping www.example.com
PING www.example.com (93.184.216.34): 56 data bytes

64 bytes from 93.184.216.34: icmp_seq=2 ttl=46 time=98.498 ms

Code: Select all

Ubuntu 14.04 Server

$ nslookup www.example.com.

Non-authoritative answer:

$ ping www.example.com
PING www.example.com (93.184.216.34) 56(84) bytes of data.
64 bytes from 93.184.216.34: icmp_seq=1 ttl=47 time=1.08 ms
64 bytes from 93.184.216.34: icmp_seq=2 ttl=47 time=0.992 ms

Just want to chime in because I have been having the exact same problem and found this thread searching for a resolution... a previously working configuration has recently started giving the same error in Tunnelblick (I can't say when it started with certainty, because several weeks had elapsed between VPN logins from the Mac client).

Client is running Tunnelblick 3.4.2 on OS X 10.10.1. Server is a Raspberry Pi running OpenVPN 2.2.1 on Raspbian.

Just like Kamal is observing, DNS is resolving on both client and server - on the client it is just resolving outside the VPN, despite checking the "Route all traffic through the VPN" option in Tunnelblick. I have made no configuration changes since the last successful use of the VPN, other than software updates.

I was starting to think it was a Yosemite issue, but perhaps it's an issue with Tunnelblick 3.4.2.

I'm also having the same problem.
Client is running Tunnelblick: OS X 10.10.1; Tunnelblick 3.4.3 (build4055.4198); prior version 3.4.2 (build 4055.4161)

And the servers are multiple openvpn and ubuntu versions.

It would be useful if somebody posted full client and server logs at verb 4 and full config files.

Please check that the problem is not related to this:
topic18043.html#p48808

Also, I notice this:

Code:
server-bridge 192.168.1.19 255.255.255.0 192.168.1.240 192.168.1.254
There are two points to be aware of:
  • NOTE: your local LAN uses the extremely common subnet address 192.168.0.x or 192.168.1.x. Be aware that this might create routing conflicts if you connect to the VPN server from public locations such as internet cafes that use the same subnet. I would change the subnet !
  • 192.168.1.19 is the server IP address - From the Manual:
    The Manual wrote:The gateway and netmask parameters to --server-bridge can be set to either the IP/netmask of the bridge interface, or the IP/netmask of the default gateway/router on the bridged subnet.
    So you could try setting --server-bridge 192.168.1.1 etc (assuming 192.168.1.1 is the default gateway for the LAN).

If you note the timestamps you will see that the "Connection refused" errors in the server log start when I disconnect the client. Is there some more graceful disconnection procedure that the server should be following?

Will play around with this to see - thanks.

Yes, changing the subnet is on my (long) list of IT to-do's. But I have verified that the local subnets I have been connecting from are NOT 192.168.1.1, so it doesn't explain my issues.

I will try changing server-bridge as specified to see if that fixes things...

Using --explicit-exit-notify is the best practice (*for UDP connections / TCP does not require this and is not compatible) push it to the client.

See --explicit-exit-notify in The Manual v23x

Just to follow up on this:

The problem resolved itself, perhaps due to a Tunnelblick and/or Yosemite update. I made no changes to either my server or client configuration, other than to push "explicit-exit-notify" to clients as discussed by Traffic.

The only material configuration changes (as far as I can tell) are that Yosemite was updated from 10.10.1 to 10.10.2, and Tunnelblick from 3.4.2 to 3.4.3.

I'm curious to hear if any of the other Mac users on this thread experienced a similar "miraculous" recovery.

Thanks for letting us know 8-)

Just one thing:

Should be 8.8.4.4
