Der Harald Welte First of all thank you for your reply. I tried again today and now I have this problem. Early preparations: Create a linux (debian11) (this server server) Install the following dependencies osmocom-latest_1.0.0_amd64.deb libosmocore20_1.8.0_amd64.deb libosmocodec0_1.8.0_amd64.deb libosmoisdn0_1.8.0_amd64.deb libosmogsm18_1.8.0_amd64.deb libosmocoding0_1.8.0_amd64.deb libosmovty9_1.8.0_amd64.deb libosmogb14_1.8.0_amd64.deb libosmoctrl0_1.8.0_amd64.deb libosmosim2_1.8.0_amd64.deb libosmousb0_1.8.0_amd64.deb libosmocore_1.8.0_amd64.deb Then I cloned two linux (debian11) one for the card reader part (bank) and one for the client-st2+simtrace2 part. bankd install dependencies libosmoabis10_1.4.1_amd64.deb libosmo-rspro2_1.0.0_amd64.deb osmo-remsim-bankd_1.0.0_amd64.deb Installed pcscd, opened pcsc and set "1", "0", "HID Global OMNIKEY 6121 Smart Card Reader [OMNIKEY 6121 Smart Card Reader] 00 00" in the csv file I run the program and wait till this

I first checked port 9999. This is the port on my bankd side, and it shows that it is being occupied by osmo-remsim. Because I read your reply that you need to bind the local port now, so I set -I, but when I set it like this, I enter the first command, it shows that my port is occupied, bankd can’t start, when I try it for the second time. The port -p 1314 is specified, and bankd is successfully started, which can also be seen in the banks of the server. But client-st2 reads port 9999, which is very contradictory.I think port 9999 of bankd is the same as port 9998 of server. It should not need to be set, but if it is not set, it will prompt an error! Why?
I also have a particularly annoying problem because I'm looking at Penetration simulation osmo-remsim is a separate project that allows placing the card/SIM in a different location than the modem/phone. It also allows management of multiple cards and emulators. It's a bit complicated to set up though.
Add the osmo-remsim repository on each host where you want to manipulate parts of osmo-remsim (so you don't have to compile osmo-remsim yourself) Run the server. This is the core instance of telling the bank which card reader to use and which bank the customer should contact. He told us that we must add the osmo-remsim library, Is this library osmocom: up to date? And when I install the binary package independently, bankd.server. client-st2. They have their own dependencies. I just need to install them and install their dependencies in different linxu, is that possible? Other packages also need to be installed at the same time. (Because I saw that there are many installation packages in the binary package) What I want to try is osmo-remsim. Can someone give me an exact answer?
Dear gmaillee,
sadly I am not able to follow your problem description.
We generally expect that our users are familiar with GNU/Linux and the installation of software packages via apt / repositories.
When using the osmocom:latest or osmocom:nightly package feeds, you do not need to worry about any dependencies. All of the dependencies are automatically installed by the package management system (dpkg+apt on Debian/Raspbian/Ubuntu)
It looks like a classic port-binding confusion between server and bankd roles. Port 9999 already being in use explains the bind error, while switching ports resolves it locally but breaks expectations on the client side. It’s a bit like Stickman Hook—one small timing or positioning mistake, and everything feels off until you realign the setup. https://stickmanhook2.org/online
