I suspect this is a dns issue. I'm hosted at Digital Ocean and my ns records at my registrar all point to ns1.digitalocean.com, ns2.digitalocean.com and ns3.digitalocean.com for all of my domains (myhostname.com, mydomain.info). At Digital Ocean my DNS records are: myhostname.com: $TTL 1800 @ IN SOA NS1.DIGITALOCEAN.COM. hostmaster.myhostname.com. ( 1387510867 ; last update: 2013-12-20 03:41:07 UTC 3600 ; refresh 900 ; retry 1209600 ; expire 1800 ; ttl ) IN NS NS1.DIGITALOCEAN.COM. NS NS2.DIGITALOCEAN.COM. NS NS3.DIGITALOCEAN.COM. MX 1 ASPMX.L.GOOGLE.COM. MX 5 ALT1.ASPMX.L.GOOGLE.COM. MX 5 ALT2.ASPMX.L.GOOGLE.COM. MX 10 ASPMX2.GOOGLEMAIL.COM. MX 10 ASPMX3.GOOGLEMAIL.COM. @ IN A 123.456.789.012 server1 CNAME @ mydomain.info: $TTL 1800 @ IN SOA NS1.DIGITALOCEAN.COM. hostmaster.mydomain.info. ( 1387313990 ; last update: 2013-12-17 20:59:50 UTC 3600 ; refresh 900 ; retry 1209600 ; expire 1800 ; ttl ) IN NS NS1.DIGITALOCEAN.COM. NS NS2.DIGITALOCEAN.COM. NS NS3.DIGITALOCEAN.COM. @ IN A 123.456.789.012 I performed a clean install using the Perfect Server guide for Debian Wheezy (nginx). The hostname is server1.myhostname.com. I've created 1 client (client1), 1 website (mydomain.info), 1 ftp user (client1ftpuser) and one shell user (client1client1). The DNS records in ISPConfig for mydomain.info are: A mydomain.info. 123.456.789.012 0 3600 CNAME www mydomain.info. 0 3600 NS mydomain.info. ns1.myhostname.com. 0 86400 NS mydomain.info. ns2.myhostname.com. 0 86400 The website (mydomain.info) resolves correctly. When I attempt to access the shell (as client1client1) and wget the latest joomla package from joomlacode.org I receive the error "unable to resolve host address `joomlacode.org'" If I attempt to wget using my admin user it resolves correctly. The issue only arises when I'm logged in as the client. When I try to upload via ftps my connection is very slow (~30KBps). I've uploaded to another server server at the same node at over 1 MBs over sftp. I'm not sure if the slower speed is a result of ssl encryption or dns issues. I suspect my DNS setup is incorrect and possibly inefficient. Can you help me correct and advise on potential ftps speed issues?
