Hello Harald, Thank you for your response and apologies for the delay in mine. I am balancing this project amongst other customer facing workloads. I have now been able to successfully use cardem-pcsc with the ST2 board to access a SIM hosted by a generic card reader. My US based colleague and I will be continuing our test of the remote/server-based configuration this week. I have primarily been using the wiki entry https://osmocom.org/projects/simtrace2/wiki/Cardem during this process. We are noticing a few discrepancies between the documented process here and our real-world experience (the re-naming of '-remsim' to 'cardem-pcsc' being one example). We will happily share our experience and contribute our findings. Would it be appropriate to bring these to yourself in reply to this thread, or is there a preferred method for contributing findings? ________________________________ Marc Wilson Technical Consultant t: +44 1483 802 503 | w: eseye.com LinkedIn | Twitter | YouTube | Blog This email is from Eseye .

Hi Harald, Following the previous work in coordination with my colleague Paul Nederveen we have a functioning system with ST2. However, our end use case required significant modification of our corporate VPN. Once I have confirmed this solution, I will contribute the end-to-end solution in full detail to the Wiki. However, I am having some trouble with the repos. Are you aware of any changes to the 'osmo-remsim-client-st2' binary on the repo? I have included the output from my APT install command. Appreciate your help as allways.

Harald, Thank you for this. I have migrated my systems to the new domain/feeds. I can install with no issues now. ________________________________ Marc Wilson Technical Consultant t: +44 1483 802 503 | w: eseye.com LinkedIn | Twitter | YouTube | Blog This email is from Eseye .

We have also meanwhile started the migration to a new location of the package feeds, see https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fosmocom.o… and https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fosmocom.o… I suggest it's best if you switch to the new (downloads.osmocom.org) feeds, which should be much more stable. The software versions are exactly identical between the old and the new feeds. Unrelated to the above: It always makes sense to check what's happening in master of osmo-remsim and simtrace2. There have been significant improvements and fixes during past months. You can see he change logs at https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitea.osm… and https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitea.osm… respectively. If you want to give that a shot (just for testing), you could alwyays test the 'nightly' feed instead of the 'latest'. We're planning to tag new releases in the next few weeks, and we're always happy to hear feedback in case of any regressions before it's too late for the next release.
