What happened:
Configured access to server with SSH Portal. Direct access with standard SSH is available too.
In my ~/.ssh/config:

ForwardAgent yes

Connected to server using SSH Portal:

server:~$ env | grep SSH
SSH_CLIENT=172.16.16.25 51416 22
SSH_TTY=/dev/pts/0
SSH_AUTH_SOCK=/tmp/ssh-6tFsyytTKi/agent.11568
SSH_CONNECTION=172.16.16.25 51416 172.30.12.200 22

server:~$ ssh-add -L
error fetching identities for protocol 2: communication with agent failed
The agent has no identities.

Connected with standard SSH:

server:~$ env | grep SSH
SSH_CLIENT=172.16.0.25 49554 22
SSH_TTY=/dev/pts/12
SSH_AUTH_SOCK=/tmp/ssh-An97pQFU6G/agent.11641
SSH_CONNECTION=172.16.0.25 49554 172.30.12.200 22

server:~$ ssh-add -L
ssh-rsa A....

What you expected to happen:

SSH compatibility
ssh-agent support

I have to be able to get my forwarded SSH key when I use SSH Portal.

How to reproduce it (as minimally and precisely as possible):

  • Enable ForwardAgent yes in SSH client config
  • Start SSH Portal in Docker
  • Add one host
  • Connect to this host using SSH Portal and standard SSH
  • Check and compare ssh-add -L output

Environment:

  • sshportal --version
v1.14.1
  • ssh sshportal info

Strange. Readme state ssh-agent support, but what it means if there is no agent forwarding?

Same issue here. ssh-agent support is written in the readme but ssh-agent is not working.

This project looks great, but without ssh-agent forwarding it's almost useless...
