Core Shell 3.6 -- Now nothing works (Abnormal Disconnect)

[priller]

Hello Yang,

Core Shell updated to 3.6 and now I cannot connect to anything.

The banner says "Version outdated, please download and install the latest version of Core Helper from our website: Core Helper"

I do not have Core Helper enabled or installed (that I can find). I followed the Uninstall directions in the link, just to be sure. But, Core Shell has ceased to function.

The log is:

Equivalent Command: ssh -i "/Users/dave/Library/Group Containers/E78WKS7W4U.io.coressh.ssh/.ssh/privatekey/dave_xxxx_xxxx" -o ExitOnForwardFailure=yes -o ServerAliveCountMax=3 -o ServerAliveInterval=15 -p 22 dave@xxxx.xxx.xxx

Sorry for this issue, will release a hot-fix version ASAP.

For now, please install Core Helper to avoid this problem.

Kindly Regards,

Yang

OK, thanks. However, with Helper installed it doesn't recognize existing server fingerprints. Hope that's not an upgrade side-affect, the known_hosts file is still there. Standing by for hot-fix.

I get the same error in 3.6 and I have Core Helper installed.

Do you enabled Core Helper? Can you send me a copy of the connection log?

I'm sorry for the inconvenience, and thank you for your help.

It seemed Core Helper not enabled, please enable it in Preferences:

Yes, this worked! Thanks! I was thinking Core Helper was enabled...

Ok, I see that with Core Helper installed, Shell starts using known_hosts in the home directory. Instead of in /Library/Group Containers/E78WKS7W4U.io.coressh.ssh/.ssh

Core Shell/ Tunnel in line with your system ssh command after Core Helper installed, so that you can gain in consistency when you switch between Core Shell/ Tunnel and system ssh command.

That's also true of Setapp version of Core Shell.

But for App Store version of Core Shell/ Tunnel and without Core Helper, things slightly different. Apple requires all apps in App Store been sandboxed, we've explained it in this topic:

Privacy Policy / Core Series Apps

Security and privacy are fundamental to Core Series apps (include Core Shell, Codinn Tunnel), we have put much efforts to improve the security. And here are “Dos and Don’ts” that we (Codinn Technologies Co., Ltd.) are following to protect your privacy: Data storage Core Series apps store all their data locally on the device you use them and in your iCloud Drive if sync is enabled. Learn more about iCloud security. Passwords / passphrases stored locally All your saved passwords / passphrases …

Which means by default Core Shell/ Tunnel do not have same privileges as system ssh, and have to read/write known_hosts inside its own sandbox container as per Sandbox policy requires.
