Re: [Config] DynDNS.org on Cisco 871
I_Route,
Separately, went into the CLI and blew away the config set up by SDM.
I then mimicked your config from above ... no joy.
I am not seeing any DYNDNS-related log entries in my log file.
I changed the max interval to once-per-minute ... no joy.
Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(2)T2, RELEASE SOFTWARE (fc3)
...
ip host members.dyndns.org 63.208.196.95

add ht tp://UUUUU:XXXXX@members.dyndns.org/nic/updatesystem=dyndns&hostname=<h>&myip=<a>
remove ht tp://UUUUU:XXXXX@members.dyndns.org/nic/updatesystem=dyndns&hostname=<h>&myip=<a>
interval maximum 0 0 1 0

ip ddns update hostname cisco871.dyndns.org
ip ddns update DynDNS

no ip unreachables
no ip proxy-arp
ip nat outside
ip inspect DEFAULT100 out
ip virtual-reassembly

...
I am using show logging in order to view the log entries ...
Q: Is there another/better way to view the log entries?
Regardless, I am not seeing any entries related to ddns. If I temporarily unplug the ethernet cable for my FastEthernet4 (WAN) connection, then I see the line go down & back up, followed by DHCP assignment ... but nothing related to ddns
Thanks in advance,

| Enable ddns update debugging:
Router#debug ip ddns update
Then either watch the parser (if using console) or issue "term mon" from an SSH/telnet session and you will see the debugs.
ne difference I noticed was you do not have the host option under your FE4 interface:
ip ddns update DynDNS host members.dyndns.org
I also hard coded the hostname I used at DynDNS.com in to the update and did not use the "h" option.

| Thank you for showing me how to enable debugging of ddns.
I found that I did not have the question marks (?) in my URLs.
I thought that I had checked that ... given the difficulty of entering question marks through the CLI (Ctl-V ?) ... but you can see in the listing above that they are not there updatesystem instead of update?system
My issues are getting slowly resolved ... but it is an arduous process.

| Oh, I thought you had the (?) in your config.
Do this:
1. Create a text file with the correct command line syntax for the four lines:
ip ddns update method DynDNS
HTTP
add ht tp://usename:password@<s>/nic/update?system=dyndns&hostname=YOURHOSTNAMEHERE&myip=<a>
interval maximum 10 0 0 0
2. Save the file as ddns.cfg or something you can remember
3. Place the file in your tftp root directory. (I use PumKin tftp server on my laptop. You can select where the files are served from)
4. On your router, copy from tftp to your running-config. Select your tftp server address and the file you created above. This will copy the entries from the text file to your running config and you will now have the (?) in the right place.

| That is what I was trying to do when I uncovered another problem.
I cannot tftp the full config because it croaks upon seeing the rsa certificate data.
Your message says that when I do a copy tftp: running-config then it does not need to be a full config ... I did not realize that ... I have ordered 3 Cisco books. |

| That is correct. It will copy whatever is in the text file you tftp and it will NOT over-write the other portions of the config.
Perhaps you could come to our Boxborough facility for a tour one day. I travel allot but I am here occasionally......
