You are in: IBM i OpenSSH & OpenSSL - Navigation > SSHD Bind to IPv6 Error Messages.
At startup time for the SSHD daemon job, it attempts to bind to both the IPv4 and IPv6 loopback addresses. In the case where a customer isn't starting the IPv6 protocol, the bind fails for IPV6 and outputs the following two error messages:
sshd[574904]: error: setsockopt IPV6_V6ONLY: Protocol driver not attached.
sshd[574904]: error: Bind to port 22 on :: failed: The socket name is already in use..
The customer can do either of the following options if they want to suppress the messages:
1) Start the IPV6 protocol using parameter STRIP6(*YES) on the STRTCP command
sshd[574904]: error: Bind to port 22 on :: failed: The socket name is already in use..
The customer can do either of the following options if they want to suppress the messages:
1) Start the IPV6 protocol using parameter STRIP6(*YES) on the STRTCP command
-or-
2) Uncomment "ListenAddress 0.0.0.0" in there sshd_config file and restart the sshd daemon job. This seems to tell the SSHD daemon job at startup time to only bind to the IPV4 address.
