Description
I have a host with multiple interfaces and addresses. Therefore I'd like to have the dedicated SSH daemon listen on only two particular addresses. In my case a IPv4 and a IPv6 address.
The configuration parameter SSH_LISTEN_HOST does not seem to accept more than one address and defining it on a second line will overwrite the first one.
I tried the following combinations:
Try 1:
SSH_LISTEN_PORT = 2222
SSH_LISTEN_HOST = 10.10.10.10 [2001:0db8:85a3:08d3:1319:8a2e:0370]
Result try 1:
2020/08/03 17:12:09 ...s/graceful/server.go:79:ListenAndServe() [E] Unable to GetListener: address 10.10.10.10 [2001:0db8:85a3:08d3:1319:8a2e:0370]:2222: too many colons in address
2020/08/03 17:12:09 .../ssh/ssh_graceful.go:23:listen() [F] Failed to start SSH server: address 10.10.10.10 [2001:0db8:85a3:08d3:1319:8a2e:0370]:2222: too many colons in address
Try 2:
SSH_LISTEN_PORT = 2222
SSH_LISTEN_HOST = 10.10.10.10,[2001:0db8:85a3:08d3:1319:8a2e:0370]
Result:
2020/08/03 17:13:56 ...s/graceful/server.go:79:ListenAndServe() [E] Unable to GetListener: address 10.10.10.10,[2001:0db8:85a3:08d3:1319:8a2e:0370]:2222: too many colons in address
2020/08/03 17:13:56 .../ssh/ssh_graceful.go:23:listen() [F] Failed to start SSH server: address 10.10.10.10,[2001:0db8:85a3:08d3:1319:8a2e:0370]:2222: too many colons in address
Try 3:
SSH_LISTEN_PORT = 2222
SSH_LISTEN_HOST = 10.10.10.10, [2001:0db8:85a3:08d3:1319:8a2e:0370]
Result:
2020/08/03 17:23:24 ...s/graceful/server.go:79:ListenAndServe() [E] Unable to GetListener: address 10.10.10.10, [2001:0db8:85a3:08d3:1319:8a2e:0370]:2222: too many colons in address
2020/08/03 17:23:24 .../ssh/ssh_graceful.go:23:listen() [F] Failed to start SSH server: address 10.10.10.10, [2001:0db8:85a3:08d3:1319:8a2e:0370]:2222: too many colons in address
Try 4:
SSH_LISTEN_PORT = 2222
SSH_LISTEN_HOST = 10.10.10.10; [2001:0db8:85a3:08d3:1319:8a2e:0370];
Result:
Will only listen to 10.10.10.10 but not 2001:0db8:85a3:08d3:1319:8a2e:0370
Workaround: comment SSH_LISTEN_HOST so the gitea SSH daemon will listen on every device and firewall undesired access.
