OK, the first thing to say is that if you are experiencing problems while using IBC, you should post here and attach the IBC logfile so that I can have a look at what’s going on. And I mean attach the logfile, don’t just quote its contents inline in your post. And also, include the whole logfile – don’t try to extract the bits that you might think are relevant, because invariably when people do this it just wastes time because I just have to go back to them and ask them for the whole thing.

?

The next thing is that you should upgrade to the latest IBC version, which is 3.18.0.

?

The third thing is that you seem to have some misunderstandings about what IBC does. It doesn’t do anything at all that influences the way TWS works. It just acts like a user so that certain things happen without the user having to initiate them. So when you say things like ‘…when it alters the TWS files during its initial run..’ that’s just completely wrong. It doesn’t alter any TWS files. TWS running under IBC is exactly the same as TWS running manually, with the exception that IBC doesn’t use the script (in Linux/macOS) or the tws.exe (on Windows) that the desktop shortcuts point to.

?

And the final point is simply that you cannot avoid having to do the 2FA. The days when you could automate the whole thing and never need to have human involvement are long gone, and to be honest I’m astonished that you still seem to think that ought to be? a possibility. However if you set it up properly, all you need to do is once a week handle the alert from IB on your cell-phone or tablet: that’s about as minimal as you could ask for.

?

So in my case, I start my live TWS on Sunday evening, I handle the alert some time later (depending on when I remember and whether I have my phone handy), and that’s it: it runs flawlessly for the rest of the week until Sunday.

?

So get me the logfile please! I would appreciate it if you move to 3.18.0 before you do that – it might just make a difference; but that’s not essential.

I don’t want the launcher logs, I want the IBC logs.

?

When you run IBC a prominent banner window is displayed telling you where the IBC log is. That’s what I need. The launcher logs are written by TWS and contain nothing relevant to IBC at all.

Look in twsstartmacos.sh. You’ll see the setting for the LOG_PATH variable. The log files themselves have names like this:

?

ibc-3.18.0_TWS-1025_wednesday.txt

?

Now read the descriptive comment further below. For your convenience, this is what it says:

?

#?? LOG_PATH

#

#???? Specifies the folder where diagnostic information is to be logged while

#???? this command file is running. This information is very valuable when

#???? troubleshooting problems, so it is advisable to always have this set to

#???? a valid location, especially when setting up IBC. You must

#???? have write access to the specified folder.

#

#???? If no value is set, log information is sent to the terminal window.

#

#???? If the setting is removed entirely (or commented out), no log information

#???? is captured at all (but this is not recommended).

?

I presume you are using twsstartmacos.sh to start IBC? If you aren’t, then how are you starting it?

?

Chen, Brian, any progress, or questions, or further input on this?

?

It occurs to me that perhaps you’re using ib_insync, which I believe will start TWS for you automatically (using IBC under the hood, if I recall correctly)? If that’s the case, please let me know.

?

Otherwise, I can’t help you until you give me some information that I can use.

?

That explains a lot!

First, my advice would be to not take ‘advantage’ of ib_insync’s ability to auto-start IBC/TWS, and just run IBC separately. I don’t use ib_insync at all, so I really don’t know how well it’s integrated with IBC , whether it would support auto-restart and 2FA etc. Ewald is a top-notch developer so more than likely he’s got it licked, but keeping them separate may be advantageous. For example, what happens if you want to run more than one API client program? Anyway, perhaps something to consider..

Regarding Ubuntu Server, being not a fan of Linux (my negative attitude to all things Unix goes back to the mid 1980s!) I found it a bit of a struggle to get my server up and running, but it is still running, sitting there unloved because after getting it all to work on Ubuntu I moved TWS back onto my Windows Server. And now I can’t actually remember what I have to do to even get a terminal session running on the Ubuntu Server via VNC! I’m sure I’d get the hang of it again if I spent a while trying, but I don’t feel much motivation to do so.

?

So I really can’t remember what libraries I had to install to make it work, apart from the libnss3.so, and at the moment I can’t even poke around inside it see what’s what. I’ll sleep on it, and perhaps a way forward will penetrate into my skull.

?

[Some time later…]

?

Aha, I’ve remembered how to get a terminal window visible in VNC. So I can get things like xeyes running, and I’ve still got the crontab I set up for starting IBC automatically (relevant lines commented out since I don’t wat it running there). But I’ve no idea how to discover what extra installs I had to do. So I’m not really any further forward. Any suggestions?

?

And now I really have to go to bed.
