[WAD] inetd + lighttpd + REMOTE_ADDR environment variable change

Added by vlrk 2 months ago

Hi team,

Using the inetd with lighttpd with below as config.

80www stream tcp6 nowait 1006 /sbin/lighttpd -1 -i 1200 -f /var/etc/lighttpd.conf

I use REMOTE_ADDR variable for the one of the validation purpose.

When I used to run as daemon , it was perfect with x.x.x.x . Now with inetd I get different value as "::ffff:192.168.1.1"

Any idea why this difference ?.

Thanks
vlrk

You can check if the inetd on your system allows you to configure the listening addresses to enable IPv4-mapped or not (setsockopt() IPV6_V6ONLY), or check your OS settings.

Why are you using tcp6?

Hi glen,

Currently in my target board , running bit older inetd version (probably adapted from uclinux distribution).
This only support tcp6 or tcp as protocol.
Here I need both ipv4 and ipv6 to be supported for 80 port , so the reason keeping tcp6 here.

Thanks

lighttpd run as a daemon sets up listening sockets and lighttpd.conf server.v4mapped = "disable" is the default.

lighttpd -1 is being passed the connected socket by inetd. Learn how to configure your inetd and your kernel, or, better, handle ipv4-mapped addresses in REMOTE_ADDR for your validation purposes.
