[Cerowrt-devel] Request for the inclusion of 2 additional packages- curl and libcurl

[Fred Stratton]

Keeping a Hurricane Electric tunnel up through a change of ipv4 address 
has always been problematic with ceroWRT.

After experimentation with openWRT Barrier Breaker, which itself does 
not perform adequately in this regard, I found that

  /usr/bin/curl -s 
'http://ipv4.tunnelbroker.net/ipv4_end.php?ip=AUTO&pass=(md5sum-of-password, 
or plaintext-updatekey)&user_id=(user-id)&tid=(tunnel-id)' > /dev/null 2>&1

works to update the endpoint from ceroWRT, either in a cron job, or in a 
script in rc.local, or both. I have yet to craft anything more 
sophisticated.

wget as included produces errors, even if correct values are included 
for all tunnel variables.

curl, and the required libcurl, work.

The error HE returns is:

It's possible to add the ipv4 endpoint update mechanism as a provider to
the dyndns update mechanism. Had a patch lying around that did that
which I may or may not have misplaced. Will see if I can find it somewhere...
