"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger

"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro via Email

"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post

"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email

"I was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email

"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry

"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum

"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen

"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

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,
