Linux: AirVPN Suite 1.1.0 beta available

Hello!

Is htop working in Irix or Solaris mode? Can you also compare with absolute values for a consistent evaluation? On equal grounds, both Hummingbird and Bluetit should need the same CPU power, because the "inner engines" which handle 99% of the math load (OpenSSL and OpenVPN) are the very same. Here, one of the most important variables which can change dramatically CPU load is the bandwidth. In Linux 64 bit both Hummingbird and Bluetit use the same OpenVPN3 version linked against OpenSSL.
 
About Eddie, it's perfectly normal that it needs very little CPU time, because it's an interface. Again, encryption/decryption are performed by OpenVPN2/OpenSSL or Hummingbird/OpenVPN3/OpenSSL, which are invoked by Eddie.

Kind regards

Thanks so much for your quick response!

As for your question on htop, I don't know the mode, and I can find nothing in the man page for it to help me to determine how to answer it. I've attached a screenshot of what I see in whatever mode I have it in. I do have it in "tree mode" if that's important. If there's an alternative view you'd prefer, please let me know.

Also, I realize that bandwidth is the foremost factor in cpu load on various vpn instances, but I'll do the comparison within a few minutes of one another with whatever I have going to demonstrate for you what I'm seeing. It's a typical day for me. :)

Oh, and again, this is on an up-to-date Fedora system, albeit running a 5.10 kernel due to existing problems with suspend on devices running the amdgpu kernel module.

Thanks again!

cheers,
john

I can confirm similar behaviour. On a Debian 10 x86_64 device, top is showing that bluetit used 7-8% CPU. The interesting thing is that nothing is connecting to bluetit and it has no configuration, other than the default, so that CPU represents bluetit's unloaded state. Here are the top figures taken over a 90-second(-ish) period (ie every 3 seconds):

Hello!

About Irix and Solaris mode:
https://logic.edchen.org/irix-mode-vs-solaris-mode-in-top-command/

@air2157

It should be fine, but anyway let's see absolute values (i.e.: 8% of what?) as we asked. Compare the CPU relative usage you get with the global, idle CPU percentage, for example (in top switch to CPU mode to get an exact overview).

Practical example for you both: in the FreeBSD system this Staff member is writing from, in this very moment top works in Irix mode and CPU mode. It shows that Xorg uses 82% of a CPU, which in turn is 97% idle, so Xorg takes 82% of 3% = 2.46% of global available CPU time..

Kind regards

Hello and thank you!

We're glad to inform you that both bugs have been reproduced, isolated and fixed. You will be able to test the fixes in the coming version in the next couple of working days..

As I'm sure you know, the default on Linux is Irix mode.

Let's take a brief look at the last 5 lines in my post, since the CPU there is pretty stable:

 
  837 root      20   0  129260  13732   9976 R   7.0   3.4   0:14.80 bluetit                                                                          
  837 root      20   0  129260  13732   9976 S   7.3   3.4   0:15.02 bluetit                                                                          
  837 root      20   0  129260  13732   9976 S   7.3   3.4   0:15.24 bluetit                                                                          
  837 root      20   0  129260  13732   9976 R   7.3   3.4   0:15.46 bluetit                                                                          
  837 root      20   0  129260  13732   9976 S   7.3   3.4   0:15.68 bluetit
As you can see, the actual CPU time consumed during each 3-second period is 0.22 seconds. If we divide 0.22 by 3, the amswer is 0.07333, so 7.3% correctly represents the CPU use.

That said, I'm running the test in a VM and top is showing a relatively high number of hardware interrupts (hi)  and (VM-related) steal time (st), so perhaps these are related to my testing environment.
%Cpu0  :  0.0 us,  0.0 sy,  0.0 ni, 93.2 id,  0.0 wa,  4.3 hi,  0.0 si,  2.5 st
%Cpu1  :  0.3 us,  0.3 sy,  0.0 ni, 99.0 id,  0.0 wa,  0.3 hi,  0.0 si,  0.0 st

Hello!

Yes, it sounds definitely fine. It's 7.3% of 6.8% in the worst case, as far as we can see from your pastes, i.e. less than 0.5% of total CPU time.

Kind regards

While "steal time" will be VM-related, are you saying that the hardware interrupts are definitely an artifact of the VM environment?

It would also be useful to know if @jrredho is using a VM.

I guess I see that the total cpu time is small, so thanks to you both for sorting through this for me!

The problem I was hoping to describe was a little bit different. Specifically, I was asking why, exactly, the relative cpu use differences were so large. Typically, I see an order of magnitude differences in each step comparing running eddie-cli vs eddie-ui vs bluetit. Maybe that's just an artifact of being so down in the noise, as it were?

And now, with all of my mucking about with my system, again Fedora f33 workstation (and @air2157, this is not on a VM, but on a dual-booted standalone system), I cannot get the goldcrest/bluetit combo to run at all. In fact, when I do fresh install of the latest Suite 1.1RC1: (1) Permissions and modes on hummingbird and goldcrest in /usr/local/bin aren't set correctly by the installer, and, if I manually change them, both versions of eddie will put hummingbird in a loop that dumps a core every time through; and, (2) When I run goldcrest, bluetit crashes and dumps a core. I suppose that the former is not the subject of this entire thread, so I'll take that to another, more appropriate, place.

As of now, I may have to just uninstall all versions of Eddie and Suite, and start from scratch...

Thanks again!

cheers,
john

That's very strange, but telling us that they were incorrect is only half of the story. What were the settings you saw?

FYI, the permissions on the tar file are 755 (rwx-r-xr-x)
-rwxr-xr-x 1 user user 4097744 Apr  7 11:36 bluetit
-rwxr-xr-x 1 user user  250544 Apr  7 11:36 goldcrest
-rwxr-xr-x 1 user user 3703864 Apr  7 11:36 hummingbird
and the install.sh script simply copies them over. (Did you remember to use sudo install.sh?) Perhaps you have some security system, such as AppArmor, on your system that's screwing thing up.

Ack! You're right, and you've just told me what happened, and, I think, what probably should be done with the install script to make it just a bit more robust: All users have to run the install.sh script as root or via sudo, but, if they're like me, they often extract the tar file as a non-root user; my non-root user (self) has a umask of 0077 set in my .bashrc. :)

The installation script sets the appropriate permissions in /etc/airvpn explicitly. I think it should do the same for all installed files, including those installed to system directories.


Thanks to you and to @Staff for helping me better understand how to get this all installed correctly! Now I can go back and re-examine how to get all of this running correctly on my system.

cheers,
john

Hey All,

I know I wrote earlier that since I wasn't so helpful on the whole beta testing side of things, but now I'm going to renege on that. Sorry.

Anyway, since this latest version of the Suite contains an April update to hummingbird, and thanks to the kind help of some of you on this thread, I've now progressed to spending some time sorting out some the SELinux business on my Fedora system.
Along the way, I've tried using hummingbird with the two eddie clients, and this latest version crashes with a segmentation fault on my system.

Here's what I see in journalctl:

  libc.so.6 and libpthread.so.0: glibc-2.32-4
  libstdc++.so.6: libstdc++-10.2.1-9

If there's something obvious on my side of things that I can do to help debug and to resolve this, I'm very happy to give it a try.

[Edit: I should also note that the June 2020 edition of hummingbird works fine  with these libraries.]

Hello again

I have been using Linux Airvpn suite since it was introduced.
I am intrigued and I have to finally ask this question -

When using this goldcrest command :

goldcrest --air-connect --air-country GB --air-key DESKTOP --cipher CHACHA20-POLY1305 --air-6to4 on  --network-lock nftables

Every single time I connect to the UK server Chow.

This is the server selected every single time over the weeks and months of use.

The line in the log below :
Connected to currently best AirVPN server in United Kingdom

cannot be correct every single time of use can it ?
The server stats webpage changes frequently to show the 'best' server for the United Kingdom.


If it helps :

Hello and thank you!

We can't reproduce the issue, can you see how Eddie runs Hummingbird in your case? If you tick "Debugging log" option in "Log" window Eddie log verbosity will increase and Eddie should print all the commands it runs. Please check also the profile that Eddie generated, which is then passed to Hummingbird. You can see it by double-clicking the "generated configuration" line in the "Stats" window.

Kind regards

Hello!

Under your conditions, Bluetit resolves gb3.ipv6.vpn.airdns.org. We might have some issue with records update, at least for AAAA, so the problem is not in Bluetit. We are investigating, thank you, it is a useful head up.

Kind regards

Thank you so much for continuing to help me sort through all of this!

It took me some time to get back to you due to the fact that I wanted to re-initialize SELinux settings, which meant doing the whole remove, install, and reconfigure circuit. But I *think* I've got better info for you, although I did not yet get the "generated profile info" for you as I'm now connected using eddie-ui via OpenVPN, so the configuration would be incorrect. Regardless, I hope what I've got for you here will be informative.

First, I'm attaching the eddie system report that's compiled in the eddie-ui application; it is in the attached file eddie_system-report. Second I'm attaching the relevant section from journalctl; it is in the attached file, eddie_journal-log. Finally, I set the logging up in Eddie as you instructed; that log for your latest version of hummingbird is in the attached file eddie_2021-04-13.log

Thanks again for all of your help. I'll follow up as soon as I've had a chance to re-create the hummingbird scenario with the profile info you asked for.

cheers,
john

Hello!

We're glad to inform you that AirVPN Suite 1.1.0 RC 2 is now available. Diownload URLs have been updated accordingly in this thread first message.

AirVPN Suite 1.1.0 RC 2 includes NEW OpenVPN AirVPN library 3.7 fixing a couple of issues coming from the main branch causing the library to crash under the conditions found by our community testers and reported in this thread: thank you all! Another issue in the library was the confusion between "proto tcp-client" and "proto tcp" in OpeNVPN 3 main branch, which caused a critical problem as reported in this thread by testers. The issue has been addressed.

OpenVPN AirVPN 3.7 is now 100 commits ahead of the main branch, featuring several, new important features and very many bug fixes.

A small change in Bluetit will also cause less CPU usage, at the price of a slightly lower responsiveness (which will not be seen by the naked eye). The main load was caused by the handling of the D-Bus message queue, which is critical because D-Bus does not have a message buffer: if the listener loses a message that message will be lost for good. Through an appropriate fine tuning, now Bluetit will not lose any message but at the same time will need less CPU time. Thanks again to our community testers for having reported the matter in this thread.

Please keep testing RC 2!

Kind regards

Real trouble using RC2

1# on goldcrest command :

peter@desktop:~/Desktop/VPN$ goldcrest --air-connect  --air-server Alathfar 

normal start of server but on using CTRL +C to terminate  the last line shows :

^C2021-04-15 15:40:30 Caught SIGTERM signal. Terminating.

but that is where it stops............
and the server remains connected.

Full log :

UPDATE TWO
I cannot stop goldcrest using htop either.

Restarting the computer results in a 30 second delay on shutdown  with :

'A stop job is running for session 1 of user peter' showing in close down terminal

Hello!

We're glad to inform you that AirVPN Suite 1.1.0 RC 3 is now available. Download URLs have been updated in this thread first message.

AirVPN Suite 1.1.0 RC 3 aims at addressing RC 2 Bluetit problem or regression suffered in D-Bus message handling and found out (unfortunately not reproduced on our systems) by our community testers @pjnsmb @leori and @colorman

Please keep testing RC 3!

Version 1.1.0 RC 3 - 16 April 2021 - changelog

  • [ProMIND] Updated to OpenVPN 3.7 AirVPN
  • [ProMIND] vpnclient.hpp: avoid netFilter setup in case NetFilter object is not private
  • [ProMIND] dbusconnector.cpp: fine tuned D-Bus wait cycle in R/W dispatch. Implemented a thread safe wait in order to avoid D-Bus timeout policy

Kind regards

Can someone walk me through the configuration process?

I installed the packages selecting yes in each case when asked.
Added lines for airusername and airpassword to /etc/airvpn/bluetit.rc

Tried to start with

goldcrest air-connect, -O 
And get the following error:

DBusConnectorException: DBusConnector: request name error "org.airvpn.client" - Request to own name refused by policy

I'm on Fedora Workstation 33

Thanks
