I'm not sure I've seen sin6_leen before. glibc does not use an sa_len field to store the length of sockaddr structs, and instead provides an SA_LEN(struct sockaddr *) macro that takes a pointer to a sockaddr field and returns its size based on the value in the sa_family field. Generally code that expects sa_len can be ported by changing code that reads sa_len to instead call SA_LEN() and simply deleting code that sets sa_len. If you're getting the error that SA_LEN is undefined, maybe you're using a different glibc than the rest of us. Check /usr/include/bits/sockaddr.h and make sure SA_LEN(x) is defined there. > I noticed a while back that ftp did not work on the only site > I used that had an IPv6 address (ftp.linux-ipv6.org), I could > only get there from an IPv4 client, is this why? Most likely IPv6 connectivity was broken for either you or them. :-) If there's an incompatibility with the sa_len field, it will be caught at compile time and you'll never even get an executable. -Nathan - -- +-------------------+---------------------+------------------------+ | Nathan Lutchansky | [EMAIL PROTECTED] | Lithium Technologies | +------------------------------------------------------------------+ | I dread success.
