Hi Trond, Anna, Steve, For kAFS, I'm writing something to allow the in-kernel DNS resolver be able to ask for a server list (eg. the list of VL servers in an AFS cell) and get back a list of servers and the addresses associated with each server. This would be requested by passing an "srv=<version>" option in the callout info. The payload handed to the kernel currently looks like something assembled from the data obtained from a bunch of SRV records that have been further looked up to A or AAAA. In the kernel it might get parsed to something like: struct address { union { struct sockaddr_in sin; struct sockaddr_in6 sin6; }; }; struct server { unsigned short port; unsigned short pref; // From SRV unsigned short weight; // From SRV unsigned char ipproto; // IPPROTO_* unsigned int nr_addrs; // May be 0 struct address *addrs; }; struct server_list { unsigned int nr_servers; struct server servers[]; }; Is this something that NFS or CIFS (or anything else for that matter) could find useful? I also have this loading information from a configuration file as a backup/override of the DNS. Could that also be useful to NFS/CIFS? David
