I’ve now got both my live TWS and paper Gateway running on my new Ubuntu Server 22.04 LTS, including auto-restarts at 05:50 GMT.

?

I’m using xvfb and x11vnc, with RealVNC viewer, so pretty much the same setup as you on the server. If it hits the same problem you described, I’ll try switching to TigerVNC as 闯ü谤驳别苍 suggested in the ‘IBC headless gateway with wsl2?’ thread.

Ok, yes I understand now where the TWS log stuff is coming from: it’s actually what’s displayed in the Gateway’s log pane at the time the window was opened or activated.

?

You didn’t say whether you tried the export DISPLAY=:0 command. The reason I thought this might help is that it’s just possible that Gateway occasionally, for some reason, spawns a separate GUI process, so it would need to inherit the DISPLAY variable which won’t happen if it hasn’t been exported. But I have no evidence that this actually happens.

?

I’ve actually just created an Ubuntu Server 22.04 LTS virtual machine so I can try setting this all up myself. I’ll let you know how I get on.

?

Regarding running on home hardware and internet connection: my internet connection is full fibre to the premises, running at 140Mbps. It’s almost completely reliable: I can’t actually recall any failures at all – other than power failures which knock out the router but are rare here these days, in spite of being in very rural Scotland (rare enough that I’ve never seriously considered bothering with UPSs). The only negative is a ping time of 34ms to the IB servers, so I’m not going to win any races to hit the latest bid or ask!

?

I run TWS/Gateway on a Dell server from 2014 (actually in a Hyper-V VM hosted on that machine). The host has two 6-core hyperthreaded CPUs, and 48GB of RAM. It’s absolutely rock solid. It also runs two sizeable SQL Server databases for market data collection, a mail server, an Ubuntu VM, and a handful of Windows VMs. The VMs are all also rock solid – except Ubuntu which I have to re-install every so often because it gets itself in a mess that I don’t have enough Linux-fu to dig myself out of.

?

I have two other physical computers of around the same age: one is a Microsoft Surface Pro 2, and the other is a desktop from a UK manufacturer. They are also entirely reliable, if a bit slow. If push came to shove, I’d be happy to run my trading stuff on any of them.

?

So I really don’t see there’s any real issue with running on home hardware. Of course, if I were running some AI-driven resource-hungry trading bot that might be a different story in terms of required computing power, but reliability is not really a factor.

?

I would also say that there’s little point in worrying about cloud servers until one has something approaching a viable trading strategy.

Well, headless running isn’t an area of expertise for me, but IBC and Gateway certainly seem to be running ok.

?

The only thing I can think of is that maybe you should add:

?

export DISPLAY=:0

?

after the xvfb command.

?

By the way, I’m curious that your logfile contains a lot of lines from the Gateway logfile. Did you edit them in? If not, how did they get there? In general it’s very rare that there’s any value in the Gateway/TWS logfiles for diagnosing IBC issues.

Yes, IBC will do this. But it may require 2FA again, So you may need to keep your phone (or other device running IBKR Mobile app) handy.

Please reply with the complete logfile – attach it, don’t quote it.

I’ve no idea what went wrong apart from the fact that the relevant jar file didn’t seem to contain the code it should.? Why that should be the case is a mystery to me, unless there was actually something wrong with the installer. ?It’s possible the installer you downloaded was faulty and IB fixed it before I downloaded it.

?

So if you actually need 10.22, it would be worth doing it again. Note that you can have any number of Gateway/TWS versions installed – they don’t interfere with each other, so you don’t need to uninstall 10.19 to try 10.22. You only need to change the major version number in the start script (and use the 3.16.3 IBC for 10.22). You could also install 3.16.3 in a different folder from 3.16.2 so if it still doesn’t work it would be easy to revert to 10.19.

Hi Richard,

?

I have gone back to gateway version 1019.1. I searched for

interactive brokers standalone gateway linux 64 installer

And finally to

[Actually the version is still incorrect – it’s not showing any version at all now! The version file should contain just “3.16.3” and nothing else. However, that’s irrelevant as far as your actual problem is concerned.]

?

Well, here’s a strange thing, I’ve compared your logfile with mine on Ubuntu 22.04 and they are identical up to the point where yours fails (except for the OS details and the username). Mine carries on fine and loads IBC with no problem.

?

I can only conclude that one of your jar files is corrupt – presumably the one that contains the main entrypoint, can’t remember which one that is. Maybe it has somehow lost its manifest?

?

As a basic sanity check, if you haven’t already done so, can you try running Gateway directly from the IB-supplied link – ie without using IBC. If that doesn’t work, then you’ll have to uninstall Gateway and reinstall. If it does work, then I’m completely at a loss – so I think I’d still recommend you uninstall and reinstall Gateway.
