Eddie 2.10.3 broken with Mono 4.4.0.40 under Linux

[zebulon 0]

Hi,

I am an Arch Linux user. Eddie 2.10.3 was working fine until they updated Mono to 4.4.0.40. It now crashes at start with this error:

Unhandled Exception: System.TypeInitializationException: An exception was thrown by the type initializer for Mono.Unix.Native.Syscall ---> System.DllNotFoundException: $mono_libdir/libMonoPosixHelper.so

The mono package comes with /usr/lib/libMonoPosixHelper.so, so Eddie may need recompilation against the new mono libraries. Unfortunately, the github version does not compile either.

This seems to be easily fixed, what is your mono_libdir?

You may want to add mono's lib dir to /etc/ld.so.conf or /etc/ld.so.conf.d/mono or wherever 
your system is configuring LD paths.

This should make Eddie find the shared object next launch, since now it is probably looking for it

in an undefined location.

 

P.S.

You may want to try this branch as well:

Well, this is very weird: this also happens when using the tarball (from Airvpn website), which contains the libMonoPosixHelper.so file. Why would the system interfere with the local version?

 

Edit: uninstalling the system package mono allows it to run. So mono interferes with the local version somehow.

I am using Arch linux(Kernel 4.4.5), and I was able to downgrade to the previously installed version of mono, which was 4.2.2.30 and it started working again...

I have opened a thread about this on Archlinux forum: https://bbs.archlinux.org/viewtopic.php?pid=1616073#p1616073

Can you try the ldd command with 4.2? There is no difference for me between 4.4 and no mono.

Here it is (with Mono 4.2.2.30)

$ ldd libMonoPosixHelper.so
linux-vdso.so.1 (0x00007ffe859d1000)
libz.so.1 => /usr/lib/libz.so.1 (0x00007f7540d73000)

libdl.so.2 => /usr/lib/libdl.so.2 (0x00007f754086a000)
libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007f754064c000)

I discussed this matter on Arch forums: it seems that some mono patches were removed, The patch named "Microsoft.Portable.Common.targets" looks like a good starting point.

Hi, it does not compile. I get this error:

I cannot find XmlItem.cs anywhere in Eddie code, or in another library. Any idea? Thanks.

Thanks this helped me too. Since i do not use mono for anything else i could just as well uninstall it, which works flawlessly.

As Requested by AirVPN Staff *I have been directed to this Post on getting help to run Eddie on Linux:

My apologies, apparently I posted in the wrong topic,
& was a little bit over dramatic!   

Today the Portable version (non mono) I was using stopped working.
*I use Ubuntu 15.10

 

~/airvpn_linux_x64_portable$ ./airvpn

I hope the above information will help developers find out why the non-mono version of Eddie stopped working. (Like others here *updates to Mono caused the standard version of Eddie to stop working on my system: Ubuntu 15.10) 
*Other programs on my system use Mono, so downgrading mono didn't seem like a good idea…

I have been advised not to use the Ubuntu Network Manager…
*I agree, because the network manager has bug which worries me: - https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1211110

So my question now is, until Eddie Portable is working again, what is recommended?
It has been suggested "a better alternative is running OpenVPN directly" as opposed to using the Ubuntu network manager!?
How?

EDIT:
OK I have had time to figure-out, and then test, using openVPN directly; 
I have CDed into my AirVPN Config folder and:
 
sudo openvpn --config AirVPN_Netherlands_UDP-443.ovpn

 

*Then I went to 
https://www.dnsleaktest.com/
and ran the extended test…
All is well, No DNS problems… 
*When I used the Ubuntu Network Manager Method, there were 'DNS Problems' (Check the Link above to the Bug report for more information, if you are interested)
OK, that gets the VPN going again, until EddiePortable is working again… 

 

EDIT:
I have had time to do more testing
There now is also a Portable version that requires Mono!
I have just tested this version on Ubuntu 15.10 with mono
*It is working!   (I also checked with https://www.dnsleaktest.com/ no problems)
(The other portable that does not require mono does not seem to work anymore on Ubuntu)

BlackArch trow the same error but with mono required version it work just fine

 

Btw the experimental version work very nicely, ssl tunnel / network lock / DNS airvpn / Switch server... Unlike the stable one which I had some hard time.

 

Gg for your work
