Intermittent Putty and Horizon connectivity -Openstack Pike

asked 2019-01-13 01:54:11 -0600

Hello Stackers

I am having Openstack Pike Installed on Virtual box 6.0 (Devstack) . I am using Ubuntu 16.04 server as platform. Created 3 network Adapter 1. Host-only 2. NAT- Provider Network 3. NAT - NAT network

All the Services inside the VM is working normal ,Haven't found any abnormality or any anomaly. But still i got this problem of intermittent connectivity to VM via putty and Horizon.

One fine day Putty and horizon will work like charm and in bad days it doesn't not respond at all. Whenever i try to connect via putty or horizon i get "Network Error: Connection time out(putty fatal error)" and "This site cant be reached" error respectively.

I tried to restart the networking , ssh service via systemctl command but didn't help.

If any one faced such issue ,please enlighten us.

I don’t see how your problem is related to OpenStack. It’s a problem with your VirtualBox networking setup. You should get better feedback in a virtualbox forum.

@Bernd Bausch it was the Org firewall issue in my case.

Hello All,

After checking the routing and Port forwarding on all the nodes (Router ,Iptables, VM Routing table , netstat etc). I found the issue on our Organization VPN firewall due to to which i was facing above mentioned issue . I contacted the IT guys to help me out but it seems the Org have strict policy over firewall they rejected the request to enable the ports .

Thanks Sheshadri
