no-ip installs but won't bounce?
 

I installed no-ip on my Slack 10.1 gnump3d server last week since I have a dynamic IP address. Their software installs ok and runs in the background, but when my IP changes my address every couple days their software doesn't bounce my new IP address back to no-ip.com. Any ideas of how to fix this...besides buying a static IP address?

Here's their download area:

In my no-ip account set-up, I have the following options:

Host Type:
A) DNS Host (A)
B) DNS Host (Round Robin)
C) DNS Alias (CNAME)
D) Port 80 Redirect
E) Web Redirect

I chose A for my server behind a NAT router and IP tables firewall-is this correct? GNUmp3d streams on port 8001-that's the only other service I need running.

Oh, I have the same problem of keeping my server going for more than 2 or 3 days with and without iptables running. I don't think it's my firewall.

I think it IS your firewall. I had the same issue myself just a few months ago and the issue (in my case) happened to be that I was not allowing outbound connections on the port that the no-ip daemon runs on (in this case the port was not open on the router, it WAS open on the server). I'm assuming that you ARE running the no-ip daemon at bootup and that your config file for it is setup correctly. Check their site and you should find the port that needs to be open in-order for the auto update to work, and then make sure that that port is open.

On a side note, why in the name of all that is holy is your IP address changing every 3 days? DHCP defaults to 7 days, and even if your IP changed the lease to 3 days, DHCP should *try* to keep the address in it's previous lease. I'm guessing that your IP REALLY doesn't want you running services on your connection.

Have you checked the status? i.e. noip2 -S
How often is it configured to update?

What do you mean my having trouble keeping your server going?

Interesting, I configured this to update every minute. The output is 5 minutes:

root@LinuxHippy:~# noip2 -S
1 noip2 process active.

Process 702, started as noip2
Using configuration from /usr/local/etc/no-ip2.conf
Last IP Address set 141.158.41.50
Account kingskid@juno.com
configured for:
host linuxhippy.no-ip.com
Updating every 5 minutes via /dev/eth0 with NAT enabled.

It seems to be configured correctly. My router's firewall is not on now-hopefully it'll keep running smoothly when my IP address changes next-I'll let people know here.

Verizon DSL has said twice that it is ok for me to run an ftp server from my house using residential DSL. They offered no tech support as to how to do this. I was told last week that my IP address would probably change daily by the networking guy at work-mine is every 2 or 3 days. I think the rules must vary from state to state and IP to IP for dynamic IP addressing.
