Help with a script

zooster · 14 Feb 2006

Thanks to this thread, I could make the dyndns work, but I'm not done yet.
I've added to debug.cfg this string:

wget -O - "http://USER[email protected]/nic/update?hostname=HOST.dyndns.org" | cat

But I would also make it update only when the ip changes.
gandalf94305(not answering anymore) suggested to use this command:

~ # multid -?
usage: multid multid [options]
options:
-? - print this help
-f - run in forground. (NOTSET)
-s - stop daemon. (NOTSET)
-p STRING - Pidfile. ("/var/run/multid.pid")
-M STRING - memory debug output. (NULL)
-S STRING - script to call when onlinestatus changes. /bin/onlinechanged")
-t - disable simple NTP client. (NOTSET)
-D STRING - switch debug logs on. (NULL)
start server: multid
stop server : multid -s

But how to use it, where??
Shall I use f.e.:

wget -O - "http://USER[email protected]/nic/update?hostname=HOST.dyndns.org" | cat | multid multid -S "/bin/onlinechanged"

??

Try this instead of your wget ... in debug.cfg:

Code:

# create date script
cat > /var/tmp/onlinechanged << 'EOF'
#!/bin/sh
case "$1" in
 online)
  wget -O - "http://USER:[email protected]/nic/update?hostname=HOST.dyndns.org" | cat
  ;;
 offline)
  ;;
esac
EOF
chmod +x /var/tmp/onlinechanged

# restart multid with new onlinechanged script
multid -s
multid -S /var/tmp/onlinechanged

It's really necessary, that you teach yourself some Linux skills first.

Mfg,

Thanks. Then this script let the box connect to DynDNS only when the ip changes...

zooster · 14 Feb 2006

Man, I've insterted that line at the beginning of the debug.cfg, this is my debug.cfg:

Code:

#!/bin/sh


# create date script
cat > /var/tmp/onlinechanged << 'EOF'
#!/bin/sh
case "$1" in
 online)
   wget -O - "http://my user:my [email][email protected][/email]/nic/update?hostname=my host" | cat
     ;;
      offline)
        ;;
        esac
        EOF
        chmod +x /var/tmp/onlinechanged

But after I've insterted your script, I don't have ENUM, WDS, International settings, and callmessage.
Did I mistake anything?

Why do you need this line?

Code:

#!/bin/sh

Greets, Oliver

zooster · 14 Feb 2006

Nope, I've deleted the first line (#!/bin/sh) but still the enum+wds+international+callmessage don't work.

olistudent · 14 Feb 2006

Are you sure that there is no error in the script?
Ist the script executet?
Check the output of ps and mount.

Greets, Oliver

zooster · 14 Feb 2006

I don't know how to check what you suggested. I just noticed that the debug.cfg(only enum, wds, international, callmessage) without the script suggested by danisahne does work. With that script, it doesn't.

olistudent · 14 Feb 2006

Okay, I've found an error.

Code:

# create date script
cat > /var/tmp/onlinechanged << 'EOF'
#!/bin/sh
case "$1" in
 online)
wget -O - "http://my user:my [EMAIL="[email protected]"][email protected][/EMAIL]/nic/update?hostname=my host" | cat
;;
offline)
;;
esac
[SIZE=4][COLOR=red][B]EOF[/B][/COLOR][/SIZE]
chmod +x /var/tmp/onlinechanged
 
# restart multid with new onlinechanged script
multid -s
multid -S /var/tmp/onlinechanged

There musst not be spaces before EOF.

Greets, Oliver

zooster · 14 Feb 2006

Thx, I've attached that script at the end of the debug.cfg, and without space before EOF. The previous patches are there and working, but I have to understand if the connection to DynDNS does work now

zooster · 17 Feb 2006

Nope, connection to dyndns doesn't work, here is my actual debug.cfg:

Does dyndns update your ip if you call

Code:

/var/tmp/onlinechanged online

Btw: Dont do this unnecessarily (if ip is already up-to-date) or dyndns will lock your account. Is your account still working?

zooster · 17 Feb 2006

The ip cannot update, neither if I reboot the box. Something doesn't work in that script...

danisahne · 17 Feb 2006

Have you tried `/var/tmp/onlinechanged online' manually? Is myuser and mypass set according to your dyndns account?

Code:

myuser:[email protected]

zooster · 17 Feb 2006

Omg! I thought I wrote the right user, but it was wrong for just one similar digit!!! I can't believe... Sorry.
Anyway I tried to do manually `/var/tmp/onlinechanged online' and it replied with an authorization error, so I checked better my user and it was barely wrong.
Thank you very much man

zooster · 18 Feb 2006

Just the last thing. In insert mode, how can I delete digits and words? When I press backspace it types other things without deleting anything.

zooster · 18 Feb 2006

Man, it didn't update itself again, I had to do /var/tmp/onlinechanged online, it replied: good ipnumber. After I checked the dyndns and it was updated so it is no automatically...

zooster · 18 Feb 2006

Nope, I retried again and it doesn't update itself. The ip is updated on dyndns only if I do "/var/tmp/onlinechanged online" or I reboot the box... Somethign ain't work in that script.
But I just remark that my 7050 is in ATA mode only, behind a modem-router.
Help plz.

The onlinechanged script cannot work in ATA mode. How do you think your box should recognize, that the dsl line disconnected?

EDIT:
First solution: Your modem-router is able to update your dyndns account
Second solution: You have to poll (lets say every 5 minutes) the IP youraccount.dyndns.org resolves to and compare it with your current IP. Then use your script, when your account is not up-to-date. Not a good solution to me.

zooster · 18 Feb 2006

My modem-router is an alcatel speedtouch pro, I don't think it can do something like that.
Why the second solution is not good for you?
