Exploring ssh between Vector Linux and Ubuntu

Exploring ssh between Vector Linux and Ubuntu

ssh server: Ubuntu

ssh client: Vector linux

Configure IP address on Ubuntu

# ifconfig eth0 172.16.0.2 netmask 255.255.0.0 broadcast 172.16.255.255 up

Configure IP address on Vector

Go to /etc/rc.d

vi rc.inet1

Change the IP address as required

Quit and save

Restart the network interface

/etc/rc.d/./rc.inet1 restart

Verify it

ifconfig eth0

Check that both hosts can ping to each other

Check sshd running on Ubuntu

root@ismail-laptop:/etc# ps -ef|grep sshd

root 3457 1 0 14:22 ? 00:00:00 /usr/sbin/sshd

root 8430 7360 0 14:57 pts/1 00:00:00 grep sshd

Now ssh from Vector to Ubuntu

#ssh 172.16.0.2

After providing the password you should be able to ssh to Ubuntu SSH server.

Note:

In case you are unable to ssh into the Vector Linux ssh server, you can also try tostop the firewall service like this:

root:# cd /etc/rc.d

vector://etc/rc.d

root:# ./rc.firewall stop

Loading kernel modules …

error: “net.ipv4.tcp_syncookies” is an unknown key

net.ipv4.conf.all.rp_filter = 1

net.ipv4.icmp_echo_ignore_broadcasts = 1

net.ipv4.conf.all.accept_source_route = 0

net.ipv4.conf.all.secure_redirects = 1

net.ipv4.conf.all.log_martians = 1

Flushing Tables …

Firewall completely flushed! Now running with no firewall.

Then try to ssh again. You should be able to ssh to the remote host.
