    580580Add correct host key in /Users/shuang/.ssh/known_hosts to get rid of this message.
    581581Offending RSA key in /Users/shuang/.ssh/known_hosts:20
    582 RSA host key for 192.1.242.81 has changed and you have requested strict checking.
     582RSA host key for 192.1.242.65 has changed and you have requested strict checking.
    583583Host key verification failed.

    585585 This type of error happens when you have previously logged in a machine with the same IP address and that machine happens not to be the same one as the VM you want to log in. [[BR]]
    586586 As a result, this error might happen a lot, especially if you have done experiments on ExoGENI before (since it always uses the same IP range for its VMs and each VM is different from each other, i.e., with different RSA keys). [[BR]]
    587  In this case, simply open ''~/.ssh/known_hosts'' and remove the line corresponding to the IP address you are trying to login. In our case here, find ''192.1.242.81'' and remove that line. [[BR]]

     589'''Enable IP forwarding and configure routing tables'''
     590 This is a very important step in terms of using ExoGENI. [[BR]]
     591 Since ExoGENI does not automatically configure IP address/routing table/IP forwarding for the user (unlike protoGENI and InstaGENI), the user needs to do it manually (or give the instructions in the RSPEC file). [[BR]]
     592 Step 1. enable IP forwarding on center node (we need to first stop a routine that over-write any network configurations in ExoGENI node): [[BR]]
     593 On center node, run the following:
     594{{{
     595 /etc/init.d/neuca stop
     596 sysctl -w net.ipv4.ip_forward=1
     597}}}
     598 Step 2. configure default routes on the rest node:
     599 On left node, run the following:
     600{{{
     601 route add -net 172.16.0.0/16 gw 172.16.2.1
     602}}}
     603 On right node, run the following:
     604{{{
     605 route add -net 172.16.0.0/16 gw 172.16.3.1
     606}}}
     607 On top node, run the following:
     608{{{
     609 route add -net 172.16.0.0/16 gw 172.16.4.1
     610}}}
     611 On bottom node, run the following:
     612{{{
     613 route add -net 172.16.0.0/16 gw 172.16.5.1
     614}}}
     615 After these steps, we can start to do the experiments on ExoGENI virtual machines!
