Re: SSH V.5.1 with Cygwin1.dll 1.7.0(0.189/5/3) 2008-12-09: Very large logon times...

Hello, Corinna,

"large" logon time means 45 - 66 secs during public key authentication 
from viewing the banner text until an simple command has been excuted 
(e.g. "uname -a"). Password authentication works faster (about 20 sec), 
but much slower than with cygwin v.1.7.0 2008-06-18 (about 2 sec for 
password and public key authentication).

We actually use cyglsa.dll because we need real user switching with public 
key authentication.

Because of the "large logon time" problems we use the version of 
2008-06-18 and not the newer ones.

I noticed also, that the accesses to the pipes did not appear in the 
cygwin versions before 2008-06-18. Anything seems to be changed after this 
date.

Thanks for your help and best regards 

Carsten Porzler
