Erik Ekman f02339b3b2 IPv6: Create single way to format IP addresses 2014-02-06 19:44:26 +01:00
Erik Ekman a1d88c4f0a IPv6 support for client (#107) 
The iodine client now supports both IPv4 and IPv6 nameservers for
sending DNS queries to an IPv4 iodined. The nameserver will
transparently handle translation between IP protocols.

Windows port needs Vista or later to support IPv6.

Erik Ekman 8baad91156 Make sure buffer is zero-terminated when getting external ip 
Also switch to HTTP 1.0 to avoid chunked transfer coding.

Erik Ekman 900647fa0c Merge pull request #4 from mscherer/systemd 
Add socket activation for systemd, with a option to stop on idle
 2014-01-29 09:25:00 -08:00
Michael Scherer abd276ed9e Add idle option, so we can stop iodine and start it on demand with systemd 2013-12-23 22:57:50 +01:00
Michael Scherer 27fb4c75cd Add support to have on demand socket activation of iodine 2013-12-23 22:57:40 +01:00
Michael Scherer 64ff684754 Fix gcc warning -Wsizeof-pointer-memaccess 
iodined.c: In function ‘write_dns_nameenc’:
iodined.c:2030:23: attention : argument to ‘sizeof’ in ‘memset’ call is the same
expression as the destination; did you mean to provide an explicit length? [-Wsizeof-pointer-memaccess]
  memset(buf, 0, sizeof(buf));

sizeof buf will just give the size of the pointer, while buflen will clean the whole
memory.

Erik Ekman 43e4fb5448 Add automatic external IP lookup via '-n auto' 
Leonard Lausen proposed iodined should use externalip.net api
to find external ip. Use -n auto to trigger a lookup.
