What feature you'd like to see or proposal(期望什么新功能/特性或者建议)

Hi, greeting from Indonesia.

I have a server that need some environment variable set on connect.
Using plain ssh client on Windows, my command will look like this:
ssh -i .ssh\id_rsa -o "SetEnv SECRET=XXX" root@host.server.net
I can see that under Bookmarks > Ssh > Settings you have ENV:LANG so I guess it should be possible for you to implement this.

Next, I can see that I can only use one Ssh tunnel at a time. If you can support multiple at once that would be cool.

Thank you for your great software, it is beautiful, I love how it looks.

Hi, let me rephrase my request. Ssh tunnel = port forwarding. You can refer to PuTTY configuration under Connection > SSH > Tunnels. In this option you can specify multiple port forwarding.

ssh -i .ssh\id_rsa -o "SetEnv SECRET=XXX" root@host.server.net

set export SECRET=XXX in login script would be same effect?

Hi @musahi0128 I am trying to add SetEnv support, can you provide a example to use SetEnv?
like ssh -o "SetEnv=DDD=xxx" execapp@23.239.5.15 'echo $DDD'?
Also do I need to set PermitUserEnvironment=yes in sshd_config to enable it?

Got it, thank you! Would remove the credentials since I already copied it.

I can login with with the credential you provided, how can I confirm the setenv I set works or not?

If you get the same value for Your Server everytime you log in, that's mean you get it right.

Which value do you mean? The SECRET? by run echo $SECRET? As I checked env do not have a SECRET, not sure if that is expected.

Nope, in this specific case it used to select which instance you will be using. That's why please check the Your Server value each time you login. In normal environment it should be possible to echo the value as you suspected.

I see, confirm it is same server every time, thank you for the help, would add support in next release, you can remove the server.
