SSHD on GIAGD
Topic: GIAGD Posted:2003-05-26
Printer Friendly:

The uClibc dev system includes SSHD, but you need to set up host keys in /etc first:

[root@crackers /]# ssh-keygen  -t dsa -f /etc/ssh_host_dsa_key
Generating public/private dsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /etc/ssh_host_dsa_key.
Your public kkey has been saved in /etc/ssh_host_dsa_key.pub.
The key fingerprint is:
xx:xx:xx:....:xx root@crackers
[root@crackers /]# chmod 600 /etc/ssh_host_dsa_key
[root@crackers /]# chmod 644 /etc/ssh_host_dsa_key.pub

Note that you will need to enable Unix98 PTY support in the kernel. This is under Character devices. You will also need to enable the /dev/pts file system for Unix98 PTYs in the file systems options.

Check out the memory usage and minimal processes running for crackers when one user is logged in as root via ssh. This has the camera module loaded as well:
