Would you mind explaining how your post is related to the topic? I fail to see how Docker Desktop would be related to 32bit containers on 64bit host.

I don’t know, tell me where should I publish?, because this feature work fine until docker desktop 4.15.0
Please guide me where I should put the post

I moved the parts of the discussion to this new topic. Since you didn’t share what Docker Desktop flavor you use, I assumed Windows.
The ssh parts needs further explanation: it provides no context what target you try to access via ssh and for what reason and if it worked with the old version.

Same thing here (happened after upgrading from 4.15 to 4.16.1) - seems to be 32bit related. Was working on previous version.

Using docker-mac (intel)

docker run --platform=linux/386 -it --rm i386/debian:10
root@71dfc1d7ca5b:/# ping
ping: socket: Function not implemented

using 64bit version works…

docker run -it --rm debian:10
root@0a4ef754f5c6:/# ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=36 time=25.3 ms

Same issue here too. Running a 32bit app in an Ubuntu container hosted on 64bit Windows 10.

errno: 38): socket error: Function not implemented

Line of code that triggers the error:
int sockfd = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

The same source works in 4.15 but errors in 4.16
