SSHD - how to run in debugging mode

kill running SSHD server first

ENDTCPSVR SERVER(*SSHD) 

then call shell

CALL QP2TERM

start SSHD server in debug mode 

/QOpenSys/QIBM/ProdData/SC1/OpenSSH/sbin/sshd -d 

in shell you should see something like this 

/QOpenSys/QIBM/ProdData/SC1/OpenSSH/sbin/sshd -d

debug1: Server will not fork when running in debugging mode.  

now you can connect sshd from ssh client ... 
and in debug console you can check new entries
