Hi.
I performed a do-release-upgrade today and it has borked my networking. The upgrade process was cut off mid-flow by me losing my connection. I have got access to the server via the console access but I cant bring the network backup and don’t know why / how.

Any ideas?
Hi, I created my first droplet couple of days back on Banglore DC. I am trying to access same from USA and it looks like it shows very high lag. Also using it via ssh with lags make it difficult to use. Following are snippet of ping command. Just to know if changing my DC to Asia or Europe would solve this problem?

Hello I am building out an infrastructure for an application that my team is building. I currently have 4 droplets (may end up being 5 droplets) each running Ubuntu 16.04. I have one droplet acting as a reverse proxy server (running NGINX), one droplet acting as my Application server, one application acting as my Database Server and one droplet is a Continuous Integration server (running jenkins). I want to make sure that all but the reverse proxy server are only accessible over the Private network that you guys provide. How ever, I obviously still want to be able to access these droplets even though they are only accessible on private Networking. How could I do this? Do I need to setup openVPN and have that connect to the your Private Networking or what? Thanks for your help!
Hello, I have four subdomains. First two subdomains are set with wildcard *.static.MYSITE.com and .*v2.MYSITE.COM Another two subdomains are set without wildcard test.z3lab.info, cms.z3lab.info Which subdomains are more correct, and why do we use wildcard? This is my zone file ``` $ORIGIN z3lab.info. $TTL 1800 z3lab.info.

How To Set Up an NFS Mount on Ubuntu 16.04 Posted Aug 4, 2016 9.7k views Networking Ubuntu Ubuntu 16.04 ============================================ Question for: https://www.digitalocean.com/community/questions What does nfs-server.service code=exited status=22 mean? [using M. Anderson's tutorial] =============================================== Log: SetUp NFS Mount Ubuntu 16.04 ============================================== This tutorial has gotten me further in getting one Ubuntu 16.04 to file share than the other 5 or so, good writing! Have searched and found no mention of status=22 here or at Ask.Ubuntu. [file folders /status/22/ for another program. ] other nfs-server.service questions do not seem to apply to this situation. # This is a home office LAN with 1 Ubuntu HP 220-110z tower and 1 Ubuntu HP Laptop and one Win 10 Laptop. [connecting with Win 10 is another matter.] # Remote superuser not wanted. I have been following M. Anderson's tutorial at: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nfs-mount-on-ubuntu-16-04 I did not know what was needed so I included I hope not too much.
