--- Comment #7 from Andreas Christ andreas.christ@runbox.com --- Thanks to Eric Pouech's hint I did some research and found the following:
https://stackoverflow.com/questions/9843178/linux-capabilities-setcap-seems-...
So it is not a bug, it is a feature. I followed the explanations in the link (see the post at the bottom) and added a file (named wine64.conf) containing the location of my libwine.so (in my case /usr/local/lib64) to the directory /etc/ld.so.conf.d/ and ran ldconfig. This resolved the ICMP issue.
Unfortunately, I get a different error message now from the FLEXnet License Finder when entering the server IP: "Network error: Server ("192.168...") not responding..." I know that the license server is up because the application I am trying to run connects to it in a virtual machine on the same host, and iexplore in the wine prefix can connect to the network (both LAN and WAN). The application itself runs nicely with a demo license file (without connecting to the license server). Anyway, I assume that this has nothing to do with the bug as it was reported here originally. So I may open up another case soon unless I can figure out a solution.
farmboy0, may I ask you to reproduce this on 32bit? I do not have an appropriate 32bit application I could test. If this resolves your problem, this bug can be closed.
