Hi Bruno,


If your software supports an encrypted access protocol such as SSH, Cisco recommends that you enable only that protocol and disable Telnet access when you want to use the SSH server. In order to enable the SSH Daemon (SSHD), you need an SSHD server license, which enables SSHD functionality on both the Standard and Enhanced versions of CSS software. Issue the sshd commands.



SSH version 1 support started in 4.01. SSH version 2 support started in 5.20.


Can you send me the output of


# sh ver


# show sshd version


# show sshd config


All your questions are answered in the following documents :


"Configuring CSS Remote Access Methods"

If you see any problems I'd appreciate being pointed in the right direction.

SSHD-0: Read from socket failed: errno = 0x36


This message is from SSH it means the CSS had a SSH connection established and was

expecting data on the connection. When the CSS went to read data from the underlying

socket the read returned an error and the message is logged and the SSH connection closed

down by the CSS. This is usually caused by an abnormal ssh session close where the client does not send a fin or rst when he closes down.
