`hostname` still shows localhost when login to a VM

[Xuan Liu]

Hello,

I recently created a custom image for InstaGENI XenVMs, and I followed the suggestion in previous topic regarding creating VM, which is to delete all personal user accounts under /users except for geniuesrs. 

When I login to some of the nodes, I found that the it shows "localhost" at the terminal (e.g. xuanliu@localhost), which is supposed to show the client id I provided in the RSpec.  I tried to reserve the resources from both Portal and Flack, and I saw the same issue for a few nodes in my slice. 

I didn't see this issue before (i.e. about a couple of weeks ago), so I'm not sure if there has been any changes. 

Thanks,

Xuan

Some examples from my current slice:

I have five nodes in my slice:

on rt-2:

xuanliu@rt-2:~$ hostname

rt-2

xuanliu@rt-2:~$ cat /etc/hosts

127.0.0.1 localhost loghost localhost rt-2.xuan-demo.ch-geni-net.instageni.illinois.edu

192.168.5.1 rt-2-lan2 rt-2-2

192.168.1.2 rt-2-stitched0 rt-2-1

192.168.4.1 rt-2-lan1 rt-2-0 rt-2

192.168.5.2 host-2-lan2 host-2-0 host-2

192.168.1.1 rt-1-stitched0 rt-1-1 rt-1

192.168.2.1 rt-1-stitched1 rt-1-0

192.168.2.2 rt-3-stitched1 rt-3-1

192.168.4.2 rt-3-lan1 rt-3-0 rt-3

On rt-3

xuanliu@localhost:~$ cat /etc/hosts

127.0.0.1 localhost localhost loghost

192.168.5.1 rt-2-lan2 rt-2-2

192.168.1.2 rt-2-stitched0 rt-2-1

192.168.4.1 rt-2-lan1 rt-2-0 rt-2

192.168.5.2 host-2-lan2 host-2-0 host-2

192.168.1.1 rt-1-stitched0 rt-1-1

192.168.2.1 rt-1-stitched1 rt-1-0 rt-1

192.168.2.2 rt-3-stitched1 rt-3-1

192.168.4.2 rt-3-lan1 rt-3-0 rt-3

xuanliu@localhost:~$ cat /etc/hostname

localhost

From rt-2, i can ping rt-3 by specifying it's client ID, which is rt-3

xuanliu@rt-2:~$ ping rt-3

PING rt-3-lan1 (192.168.4.2) 56(84) bytes of data.

64 bytes from rt-3-lan1 (192.168.4.2): icmp_req=1 ttl=64 time=0.936 ms

64 bytes from rt-3-lan1 (192.168.4.2): icmp_req=2 ttl=64 time=0.508 ms

^C

So it seems like the rt-3 has been configured at the node, but not written into the hosts file and hostname file. 

I'm also attaching my RSpec file for this example. 

Thanks,

Xuan

I also ran into to this problem, about a month ago, when creating an image snapshot.

Hi. Can you recreate your slice please; I think it might be fixed. Or
just “restart” the slivers via Flack.

Thanks Leigh, I just recreated the topology in my slice, it looks fine for all five nodes.
