 |
|
when i use option -r (Resolv your IP address automaticly) i get: | Code: | bash-2.05b# dyndnsupdate -u username:password -s dyndns -r -h mydomain.org
Resolving your ip address...Segmentation fault
bash-2.05b# |
but it works with a static ip: | Code: | bash-2.05b# dyndnsupdate -u username:password -s dyndns -a 192.123.23.4 -h mydomain.org
Connecting to members.dyndns.org...succeeded!
Update good and successful, IP updated
bash-2.05b# |
why isn't dyndnsupdate able to resolve the ip? |

| Code: | MYIP="`ifconfig $INTERFACE | grep 'P-t-P:' | awk '{ print $2 }' | sed -e 's/.*://'`"
dyndnsupdate -u username:password -s dyndns -a $MYIP -h mydomain.org |

dominik: that script doesn't work if you don't use PPP directly to connect to the 'net.
i'm having the same problem with dyndnsupdate, and i'm behind a NAT router. i can specify the IP address on the command line, but if i try to resolve the IP automatically, i get a Segmentation Fault.
has anyone had any luck getting dyndnsupdate to resolve an IP address behind a NAT router? any help would be appreciated :)... |

same problem here
Resolving your IP... Segmentation fault
Remark:
My eth1 receives the ISP IP from my Speedtouch Home ADSL Modem through dhcp spoofing. |

| Maybe it's time to give ddclient a try? I've been using it since forever with zero problems. |

it works because your using static ip  $MYIP is a constant to the script and then to the dyndnsupdate 
my sugestion is to use ddclient
it's really cool  |

Well, this is kind of flaky, but it DOES matter what order you put it in. The order that works for me is: | Code: | | dyndnsupdate -h <hostname> -r -u <username:password> |
It really shouldn't matter, but it does. Hopefully that will help dominik. |

| I use dyndnsupdate's option to get the IP address from a specified device. I can't remember the option off the top of my head, but I use ppp0 and it has never had a problem finding it from there. |

I use this same option as well, and have never had the problems mentioned above.

Hello, dominik!
Option -r not work properly.
I use instead of -r option -i <interface>,
where <interface> is external (Internet) network card.
Look for example my /etc/conf.d/local.start
| Code: |
# /etc/conf.d/local.start:
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/conf.d/local.start,v 1.4 2002/11/18 19:39:22 aza$
# This is a good place to load any misc.
# programs on startup ( 1>&2 )
echo 1 > /proc/sys/net/ipv4/ip_forward
dyndnsupdate -u username:password -s dyndns -i eth0 -h mydomain.ath.cx
|
It's work fine for me !  |
