      @sullrich:

      Everyone having problems please replace /etc/rc.newwanip with http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/etc/rc.newwanip?rev=1.21.2.23;content-type=text%2Fplain;only_with_tag=RELENG_1

      Let me know.. Thanks!

      it looks like it could work, BUT ! i got this:

      Dec 17 15:25:11 dhclient[11983]: exiting.
      Dec 17 15:25:11 dhclient[11983]: exiting.
      Dec 17 15:25:11 dhclient[11983]: connection closed
      Dec 17 15:25:11 dhclient[11983]: connection closed
      Dec 17 15:25:11 dhclient[11982]: exiting.
      Dec 17 15:25:11 dhclient[11982]: exiting.
      Dec 17 15:25:11 dhclient[11982]: wan: not found
      Dec 17 15:25:11 dhclient[11982]: wan: not found
      Dec 17 15:25:11 php: : Failed to update WAN IP, restarting dhclient.
      Dec 17 15:25:11 php: : Informational: rc.newwanip is starting.

      it seems like the script is using "wan" as a real interface name.
      maybe it should be like this ? :
      exec("dhclient {$argument}");

        I don't know if this new script fixes the Loose IP Problem. But after replacing the old version with the new one I had problems with my OpenVPN. Always the script tried to re synced the OpenVPN, I received a error:

        Port [undef] 1194 already bound

        I use the pfSense-1.0.1-Embedded.img.gz with just changing the /etc/rc.newwanip to the proposed version.

          Nextrem: not related, known issue, please see the openvpn threads.

          Everyone else:

          I have updated rc.newwanip, try this version:

          http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/etc/rc.newwanip?rev=1.21.2.24;content-type=text%2Fplain;only_with_tag=RELENG_1

              –---------------------------
              however, i dont think this script will solve the "short write: wanted 21 but got 0 bytes" error, or does it ?

                It does not solve it, it simply works around the issue for the time being.  Anyone else tested?

                  i know, but i think there is two errors,
                  first, when it failes to update the wan ip, that have been "solved" with the script.
                  but the second with "short write" will not be solved by this, i think.

                        This is starting to be render PFSense unusable for me. Every 30 bucks router can keep the ip from my isp for several months (last setup). Is it not possible to use the dhclient from the pre 1.0 versions???

                        Sorry for no better news.

                          As this problem gives biggest headaches to me, I've decided to use my linux server to run this via cronjob every minute:

                          wget -q –no-check-certificate --user=XXX --password=XXX --post-data "interface=wan&submit=Renew" http://IPOFPFSENSEGUI/status_interfaces.php -O /dev/null

                          This works fine for now. Hopefully the real solution to repair the dhclient will soon be there…

                          Cheers

                            Then use a 30$ router!  I am interested in constructive feedback, not Mr. Obvious taglines!

                              My apologies. I'm sticking with PFSense. You're doing great work.

                                Unfortunately we are using the same dhclient that we used prior to 1.0.  So nothing has changed in this regard.

                                But I do have an idea.  Give me some moments, I would like to test ISC-DHCLIENT again and see how much work it's going to be to dump the OpenBSD dhclient that FreeBSD imported.

                                  Thx alot. Due to the workaround I've got plenty of time now. Please let me know when there's something I can contribute / test in order to help.
                                  I'll watch this thread anyway.

                                    From a shell, issue this command (full installations only!):

                                    fetch -q -o - http://www.pfsense.com/~sullrich/tools/cvs_sync.sh | sh

                                    Sit back and let it do it's thing.

                                    After it is done, issue shutdown -r now or reboot from the webConfigurator or option #5.

                                        You can cancel your upgrade for now. We found some remaining issues with the new dhclient (some things still have to be changed due to different syntax). It's working on reboot though. We'll test some more things later and post when we have a new version to try.

                                            Everything should be working.  We really need ppl to test Optional WAN + DHCP more than anything at this point.  We are using the same code for dhclient as m0n0 1.3b1 now so I think it is correct.
