Introducing DigitalOcean Functions: A powerful, serverless compute solution

Question

I added VPS to one of my droplets AFTER the droplet was created, but SSH will not connect.

  • Posted July 16, 2014

I have 2 droplets, I added VPS to the second one when it was created. I just added VPS to my first droplet by following the directions from Digital Ocean. However, I cannot SSH into either droplet from the other.

DROPLET 1: eth1 Link encap:Ethernet HWaddr 04:01:1b:fe:82:02 inet addr:10.128.129.210 Bcast:10.128.129.255 Mask:255.255.255.0 inet6 addr: fe80::601:1bff:fefe:8202/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:32 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1596 (1.5 KB) TX bytes:578 (578.0 B)

DROPLET 2: eth1 Link encap:Ethernet HWaddr 04:01:1f:bc:17:02 inet addr:10.128.151.154 Bcast:10.128.255.255 Mask:255.255.0.0 inet6 addr: fe80::601:1fff:febc:1702/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5784 errors:0 dropped:0 overruns:0 frame:0 TX packets:35 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:312556 (312.5 KB) TX bytes:1826 (1.8 KB)

From droplet 2, when I use ssh root@10.128.129.210 to access droplet 1, I receive the error:

ssh: connect to host 10.128.129.210 port 22: No route to host

And, from droplet 1, when I use ssh root@10.128.151.154 to access droplet 2, I receive the error:

ssh: connect to host 10.128.151.154 port 22: Connection timed out

What am I missing?

Can you ping them from each other? Have you set up any firewalling?

(grrrr grumbling under breath) it’s always something really simple.

Thank YOU!!! They both work perfectly now.

Your mask is incorrect. It should be 255.255.0.0 (/16) rather than 255.255.255.0 (/24) in /etc/network/interfaces

Can you paste the output of ip addr, ip route, iptables-save and netstat -pnl to a pastebin?

I can ping 10.128.151.154 fine but not 10.128.129.210

EDIT: Also, “I added VPS” doesn’t make any sense, I’ll assume you meant “I enabled private networking on my VPS” ?
