ssh: Could not resolve hostname localhost:2222: Name or service not known

i followed this: https://github.com/neuropoly/sct_docker#id8

when running this:

ssh -Y sct@localhost:2222

i got this:

ssh: Could not resolve hostname localhost:2222: Name or service not known

@jcohenadad still applicable?

[jcohenadad]

yes, i tried it again and run into the same issue. A bit more verbose:

Station: OSX Mojave Opened Terminal, ran:

docker pull neuropoly/sct:sct-v4.0.0-beta.0-ubuntu-18.04
mkdir ~/docker_shared_folder
docker run -p 2222:22 --rm -it -v ~/docker_shared_folder://home/sct/docker_shared_folder neuropoly/sct:sct-v4.0.0-beta.0-ubuntu-18.04

Then opened another terminal, and ran (with error afterwards):

ssh -Y sct@localhost:2222
ssh: Could not resolve hostname localhost:2222: nodename nor servname provided, or not known

OK, it was a macOS thing. The following syntax works:

ssh -Y -p 2222 sct@localhost

I will update the documentation (assuming the above command also works on Linux???).

However, when connecting and then calling fsleyes, i get:

Unable to access the X Display, is $DISPLAY set properly?

[zougloub]

sct@localhost:2222 is a mistake even on Linux, fixed the docs.

[jcohenadad]

as for my X Display issue, is xquartz required on my Mac?

[zougloub]

I'd think so... I'm resetting a Mac to test that stuff.
