multiple dns records #48

Closed witte1000 closed 7 years ago

Hello,

Would it be possible for creating the script in that way so it can handle multiple dns records ? Let me explain.

I'm using NGINX as loadbalancer and using internal ip addressen for connecting to my webapplications who are installed on different zones.

I only need 1 public ip but multiple dns records connected to this 1 public ip.

so that I have as example

test.ydns.eu test2.test.ydns.eu test3.test.ydns.eu

all connected to 1 public ip.

I did already modify your script with copy pasting all the pieces to each other and works fine but every time researching all the script and modifying take a lot of time specially if i just want to test for a couple of hours or day's.

Also today after modifying again your script for another application what I just installed, I saw with running the script following

PRD@PRD:~$ ./YDNS_updater.sh -V [2017/09/05T11:43:47] Current IP: 213.211.142.66 [2017/09/05T11:43:47] Current IP: 213.211.142.66 [2017/09/05T11:43:48] Current IP: 213.211.142.66 [2017/09/05T11:43:48] Current IP: 213.211.142.66 [2017/09/05T11:43:49] YDNS host update failed: blablabla.ydns.eu (ok ok ok ok)

So I really mess up somewhere ....

I could use 4 or 5 scripts but it's much easier having everything in 1 script this way if I upgrade my router which cleans everything all the time (other story) I can just copy 1 script back and I'm back in business.

Thank you very much for understanding.

Kind Regards,

Dirk

Hi Dirk,

I've pushed an update for the script which allows you to use the "-H" option multiple times to update multiple hosts at once, for example:

./YDNS_updater.sh -H test.ydns.eu -H test2.ydns.eu -H test3.ydns.eu -V

You can also "hard code" the hosts into the YDNS_HOST variable inside the script: simply separate your hosts with space:

YDNS_HOST="test.ydns.eu test2.ydns.eu"

Best regards

Hello,

Thank you very much it's an illumination :)

Now I see your solution it make all sense but hadn't never can do it by myself.

However I had to modify the line 173 => put "" between the $YDNS_LASTIP_FILE

get => ./YDNS_updater_Multiple.sh: line 173: $YDNS_LASTIP_FILE: ambiguous redirect

echo "$current_ip" > "$YDNS_LASTIP_FILE"

now it's works perfectly :)

Much appreciations.

Kind Regards,

Dirk
