I I set up a nxserver at remote PC (F10 2.6.27.25-170.2.72.fc10.i686),

ssh -i /usr/NX/share/keys/user.id_dsa.key nx@server
ssh -l USER1 server

all work.

when I login via nxclient, after pass steps Connected, download
session, it failed with errors:

problem is with USER1 account.

nxuser only creates an ssh tunnel. Once that tunnel is created another
connection for nxsession is started and this user must exist on the
system and the password must be correct. I am not aware that this user
can use a public key authentication.

thanks for your reply, as you see, USER1 can login via ssh to server.
the pssword for users must be right.

where should I look for error to fix it?

I would start with the suggestions given in your own error report...

make sure that /home/USER1/.ssh/authorized_keys2 is 600 permissions
and /home/USER1/.ssh is 755 but I if I were to guess, USER1 does not
have a valid shell

Craig

thanks, after change permissions on them, the error message change to

Authentication to NX node failed.
