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 netmask broadcast 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


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


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


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.
