Solaris 10 - SSH deconnection or ssh hanging

@(#)sshd_config

Hello,

I have a platform installed with Solaris 10 on which I have some problem to connect or to remain connected.

What I noticed in the "Message" file is :

Feb 26 14:01:17 prodt10 sshd[4707]: [ID 800047 auth.crit] monitor fatal: protocol error during kex, no DH_GEX_REQUEST: 254

Feb 26 14:01:17 prodt10 sshd[4708]: [ID 800047 auth.crit] fatal: altprivsep_packet_read_expect: Monitor not responding

THe IP @ configured to access the platform is :

EthX – prodt11:aggr422003

10.161.142.6
