Author	Topic: IQFeed on Linux throws ICMP error (4 messages, Page 1 of 1)
karthikkrishnan -Interested User- Posts: 22 Joined: Nov 4, 2015	Posted: Apr 7, 2020 01:56 PM Msg. 1 of 4 I am using wine to run IQFeed and connect using python socket clients. When I run it first time, it connects and downloads the data. If I stop my client and relaunch again, it throws an error as below. 002d:fixme:msvcp:_Locinfo__Locinfo_ctor_cat_cstr (0x32e868 1 C) semi-stub 0032:err:ole:CoUninitialize Mismatched CoUninitialize 002d:err:winediag:IcmpCreateFile Failed to use ICMP (network ping), this requires special permissions. 002d:fixme:msvcrt:__clean_type_info_names_internal (0x1029f8fc) stub ^C0033:fixme:console:CONSOLE_DefaultHandler Terminating process 8 on event 0 0033:fixme:msvcrt:__clean_type_info_names_internal (0x1029f8fc) stub Has anyone been successful to have a client connect and reconnect at will ? Now I am left to kill the IQfeed process and relaunch and do it all over again [Not a workable solution]. I am surprised we still don't have a good Linux solution.

Let me know, and we may have you turn on some logging, to see what the program is doing behind the scenes.

How do I turn on more logging ?

Thing is, ping uses ICMP protocol, which in linux is somewhat privileged. So, you need to give wine the appropiate permissions in order to be able to use ICMP. Running wine as root in order to circumvent this problem would be overkill (besides a very bad thing to do!), but fortunately you can use setcap in order to grant permissions in a much more granular way. First, locate where your wine-preloader file is. In my case, it's on /usr/bin/wine-preloader . Then, type (yoo will need to sudo for this): sudo setcap cap_net_raw+epi /usr/bin/wine-preloader and that's all. Now wine is allowed to use ICMP protocol, which in turn will allow IQconnect.eze to make its "ping things" without complaining xD trade well ! Jose,
