When you're testing from the command (In reply to pyygames from comment #0) > CentOS Linux release 7.4.1708 (Core) > OpenSSH_8.2p1, OpenSSL 1.0.2k-fips 26 Jan 2017 From what I can tell CenOS 7.4 has OpenSSH 7.4: http://vault.centos.org/7.4.1708/updates/x86_64/drpms/ > RemoteForward 8888 Reverse dynamic forwarding was added in 7.6: https://www.openssh.com/txt/release-7.6 > xxxxxx omit unit session xxxxxx > [Service] > ExecStart=/usr/bin/ssh -F /etc/default/st2c2.config -NT centos2 The service is explicitly running the one in the system path. > /etc/default/st2c2.config line 5: Missing target argument. This is the error you'd get if you're using a version prior to when remote dynamic forwarding was added. > Step5 if I connect host in bellow way, it works well > ssh -F /etc/default/st2c2.config centos2 Are you sure you're using the same ssh binary version? Hello, Thanks , you are correct. They are different version binary.
