I can nslookup and dig an internal hostname, and I get a rapid response, but I cannot ping or ssh to the server. All external hostnames work fine for both ping, ssh, dig or nslookup.
ssh -vvv xxxx-xxx-xxxx-1.xxx.xxxx.net OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Reading configuration data /Users/gregcain/.ssh/config debug1: Applying options for * debug1: Reading configuration data /etc/ssh_config debug1: Applying options for * debug1: auto-mux: Trying existing master debug1: Control socket "/Usersfirstname.lastname@example.org:22" does not exist debug2: ssh_connect: needpriv 0 ssh: Could not resolve hostname xxxx-xxx-xxxx-1.xxx.xxxx.net: nodename nor servname provided, or not known
I've done a lot of searching on the net, and on this site, and it appears it's got something to do with mDNSresponder. I've added two stanzas to /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
-AlwaysAppendSearchDomains <- this shouldn't matter, since I am using FQDN. -NoMulticastAdvertisements <- I believe this one disable bonjour broadcast
I've also tried turning off mDNSResponder, but then name resolution fails outright. If I add entries to /etc/hosts, then I get working name resolution. But I need to be able to connect to DNS.
I'm pretty confident our DNS is setup correctly, as it works for everyone around me. I've also spun up a linux VM, and I'm able to connect as I would expect, using the same /etc/hosts and /etc/resolv.conf.
Any suggestions would be greatly appreciated.
