Hi shadowandy,

Can you write a similar script for no-ip.com. It also requires users to login monthly. I am not sure if a simple login is sufficient or not to keep the account active. It may be necessary to click on “Modify”, then “Update” for each host name.

Thanks,

In reply to MY. MY, Thanks for troubleshooting. Cos my username is in lowercase so didn't realise that DynDNS actually represents the username in lowercase. Glad that it works for you. :)

I figured out the problem. My Username to login the account is mixed case like: XYz. After logging in to the website, username is converted to lowercase. OUTPUT file contains “Welcome xyz”.
If I type in
USERNAME=”xyz”
then your code works.

No, not with
if grep -E “(Welcome|Hi).*$USERNAME” $OUTPUT > /dev/null 2>&1;

I changed it to read:
if grep -E “Welcome” $OUTPUT > /dev/null 2>&1;
Then it is successful.
I played with every combination of “(Welcome|Hi).*$USERNAME” . It did not work. When I login, I see Welcome XYZ, where XYZ is the username.
If you can explain ().*, that may be helpful.

In reply to MY. MY, The Welcome|Hi is actually regular expression so it matches either Welcome or Hi. Do you see that the login is successful in your router logs?

I had another curl at this location:
CURL_EXE=”/opt/bin/curl”
SO, I changed the code as above. Now, I don’t get the “Permission denied” anymore. I commented the lines as follows to see if outputs are generated.
# rm $COOKIE
# rm $OUTPUT

I think the issue is with this line:
if grep -E “(Welcome|Hi).*$USERNAME” $OUTPUT > /dev/null 2>&1; then

OUTPUT file does not have “Welcome|Hi” in it.
When I login to my account, I don’t see “Welcome|Hi”.

There is Welcome and my username.

I get this:

root@XXXXXX:/tmp/home/root# /tmp/curl –version
-sh: /tmp/curl: Permission denied

In reply to MY. MY, Can you execute "/tmp/curl --version" and paste me the version and details? If it fails to execute, do ensure that /tmp/curl is set to be executable.

I placed the file under:
CURL_EXE=”/tmp/curl”

I get
Mar 9 12:10:32 XXXXX user.notice root: DDNS_AUTOLOGIN – Login Unsuccessful

When I execute the command from Tomato Tools, System page, I get:

/tmp/DDNS_LOGIN.sh: line 23: /tmp/curl: Permission denied
/tmp/DDNS_LOGIN.sh: line 25: /tmp/curl: Permission denied
rm: can’t remove ‘/tmp/DDNSAL.cookie’: No such file or directory
rm: can’t remove ‘/tmp/DDNSAL.output’: No such file or directory

/tmp/curl folder contains 660 kb curl file without any extension and an empty folder named:__MACOSX

In reply to MY. MY, Just set the CURL_EXE variable to point to the location of the curl on the usb disk. The codes on line 25 to 28 will skip the download if it finds a executable named curl at the location of CURL_EXE.
