juče je jasko ovo postavio, ali je bio problem sa dyndns-om. jasko je našao na forumima da router ima bug za osvježavanje dyndns-a

dogovorili smo da dyndns osvježavanje prebaci na openwrt .. ali to ne radi

zadnji put je osvježavanje se desilo juče 6:10 pm

e sad ne znam da li veza prema internetu uopšte radi

našao na dlink norveškim stranicama update firmware-a (e sad ne znam koji je firmware na router-u):

Podešena je ppoe konekcija
Problem je bio sa dyndns-om prijavljuje auth failed iako je sve ok.
Napravljen passthrough na wl-hdd(192.168.0.111) za portove 22 i 80

dodijelio mu fiksnu IP

Laptopima dhcp daje parametre

dyndns

podesio dydns na wl-hdd ali ni tu 1OK

Jan  1 00:27:24 (none) : version 3.0.11b8, interface eth1, host hsabina.dyndns.org, server members.dyndns.org, service dyndns 
Jan  1 00:27:24 (none) : (hsabina.dyndns.org) unable to resolve interface eth1 

on gleda eth1 kao wan interfejs , pošto se wl-hdd ne koristi za konekciju mora se ići na web.

Našao patch ez-ipupdate-a na http://forum.openwrt.org/viewtopic.php?pid=48791
jednostavno se stavi u conf "interface=web-detect"

odradio skidanje starog, instalaciju patchovanog i podešenje i testiranje

nakon obvoga dyndns se uspješno osvježio, resetovao router ..OK

Nakon ovoga testirao laptope , sabinin je Ok ali mijin !OK net5radi mu mreža.
Kontaktirao miju kaže ima neka kutijica preko koje ide ????. Najvjerovatnije usb mrežna jer ova !OK ali je nisam mogao naći.

Potrebno ponjeti i jedan mrežni kabl za mijin laptop

na kraju sam napravio backup konfiguracije i systema

stavio sam na dir-100 da je konekcija always on , zašto je sada dyndns pukao ?? ili je konekcija pukla ili je do ovog mog podešenja patchovanog ez-ipupdate-a

najvjerovatnije sam ga trebao u cron ubaciti jer kada sad skontam webif ovaj patchovani prijavi kao broken pa ga možda i ne pokušava pokrenuti automatski

rješenje bi dakle bilo ubaciti u crontab

ustvatri moglo bi biti i da ez-ipupdate čeka update ip adrese na wan interfejsu a pošto se on ne događa on misli da ne dolazi do promjene ip adrese.

Replying to [comment:8 bjasko]:

mija misli vjerovatno na isdn pcmci modem ...

e sad što mrežna karta ne radi pojma nemam

što se tiče dyndns-s jasko je to ovdje vjerovatno našao:

http://forum.openwrt.org/viewtopic.php?pid=48791

ez-ipupdate ima daemon mode

evo primjera jednog ez-ipupdate.conf što sam našao na net-u

service-type=dyndns-custom
user=username:password
host=mydomain.com,myseconddomain.com,thirddomain.com
mx=mail.mydomain.com
interface=eth1
max-interval=86400
cache-file=/opt/tmpfs/ez-ipupdate.cache
daemon

međutim na openwrt-ovim stranicama se izbjegava ez-ipupdate

http://wiki.openwrt.org/DDNSHowTo

preporučuje se neki updatedd

Install the updatedd package and the plugin package for your DDNS service. <plugin> can be changeip, dyndns, eurodyndns, hn, noip, ods, ovh, regfish, tzo or zoneedit.

ipkg update
ipkg install updatedd updatedd-mod-<plugin>

druga varijanta je ova shell skripta

#!/bin/sh
USER="hsamra" 
PASS="hernad" 
DOMAIN="hsabina.dyndns.org" 
registered=$(nslookup $DOMAIN|sed 's/[^0-9. ]//g'|tail -n1|sed -e's/ [0-9.]*//2' -e's/ *//')
current=$(wget -O - http://checkip.dyndns.org|sed s/[^0-9.]//g)
#echo current=$current
[ "$current" != "$registered" ] && {
        wget -O /dev/null http://$USER:$PASS@members.dyndns.org/nic/update?hostname=$DOMAIN &&
        registered=$current
}

sleep 3
newip=$(wget -O - http://checkip.dyndns.org|sed s/[^0-9.]//g)
newdns=$(nslookup $DOMAIN|sed 's/[^0-9. ]//g'|tail -n1|sed -e's/ [0-9.]*//2' -e's/ *//')
echo "Set ${newip} (DNS: ${newdns}), had ${current} (DNS: ${registered})" \
        | /usr/bin/logger -t ddupd

kojom se uz pomoć http://checkip.dyndns.org utvrđuje web adresa i onda se to upisuje na server

ova skripta je skroz ok ...

na 192.168.0.111

service-type=dyndns
host=test.dyndns.org
interface=web-detect
user=test:test
wildcard

# Do not change the lines below
cache-file=/etc/ez-ipupdate.cache
pid-file=/var/run/ez-ipupdate.pid
max-interval=2592000

mislim da je ovaj max-interval sporan da je on period refreshiranja

naletio sam na ovaj ipk u /etc/init.d/ ... e tu baš ne bi trebao biti nepotrebno zauzima prostor

za to ima /tmp lokacija

osvježio sam firmware na 1.0.2 d-linka ... sada mi dyndns prijavljuje ok ažuriranje
