New Post: ForwardedPortLocal Work on Linux, but refused by server 10054 with AIX 6.1

da_rinkes, thanks your sincere reply.
Because My code was almost same as the test program, I did not show ;-)

But I got some solution on this matter,

With the userID that once I log in int the AIX server with putty or terminal program,works fine.

But newly created UserID on same AIX server that never loged-in by hand,
Connection and ForwardedPort seems go well, and just after request socket call to bound-port, then it goes to fails.

Remain My question are

• Is it same thing with - StrictHostKeyChecking option on "ssh" client?
• the SSH.NET can set this always "Yes" with "HostKeyRecieved" event?
• then Is This event occurred for newly connected "Host" Server or Newly connected "userID" even same Host.
  

I am vey new to SSH, so it is very hard to handle exception case. so far your comment very useful to me. t
