I have a Debian file server I'm accessing from windows clients. Until a power outage a few days ago I had no issues accessing via hostname. Now I must use the ip handed out by my router. I can ssh (putty) into it via hostname, but cannot ping or access my samba shares with hostname. I have rebooted my router, restarted server and client machines. What gives?

Seems that the server still knows it's hostname - just isn't resolving in some places.

tone@homeserver:~$ hostname
homeserver
tone@homeserver:~$

edit: my router (linksys running dd-wrt) tells me that all my other machines have a hostname mapped, so i strongly suspect the issue is something in the configuration of this particular machine. I also found that the hostname is not resolving anywhere (which is different from my initial statement).

  • There's some piecemeal information here. What did you use before for resolution? WINS? A DNS server? Your router handed it out? – Bart Silverstrim Sep 20 '10 at 13:40
  • Are all the systems having trouble resolving hostnames or just a few systems? – Bart Silverstrim Sep 20 '10 at 13:41
  • You said you can SSH into (a system) by hostname, but that same system can't ping by hostname to the same system? Does it resolve but not ping? – Bart Silverstrim Sep 20 '10 at 13:41
  • From the information you have given without the edit, I'd suspect that something was damaged int he router (what kind of router is it?). Inexpensive routers can do *weird* stuff when they fail. But without knowing how you had resolution set up or how each system involved is or isn't resolving, there's not much I could offer on troubleshooting. You could consider setting static IP's and a DNS server on your Debian system and use that... – Bart Silverstrim Sep 20 '10 at 13:48
  • my router hands out ips, all systems are having trouble resolving, i can ssh using PuTTY - maybe that program stores the dns?? pings do not work, will not resolve when accessing share i.e. \\homeserver\mediashare. it's a Linksys WRT54G - only 6 months old. I flashed with DD-WRT when I got it and have not had any issues yet. – Tone Sep 20 '10 at 18:31

it's working now. after a few reboots both on the server and the router. setting the ip as static and changing back to dynamic in the router it started working again. go figure.
