{section: Test required}

Don't forget to below lists.

*:Choosing a specific interface for Condor use in multi-homed IPv6 host. Use param "NETWORK_INTERFACE".

{section: currently working on}

{subsection: KeyCache}
KeyCache, uses sockaddr_in for storing ip addr. before modify, be sure to look at the overall picture. only used in condor_secman and daemon core.

KeyCacheEntry stores sockaddr_in. KeyCache converts sockaddr_in into sinful string and use the string as a key.

{subsection: Sock::my_addr() can fail?}
One of asymmetry in Sock class is that peer_addr() does not fail and always return a value but my_addr() can fail. ( peer_addr tells you the address of peer, my_addr() tells you the address of local socket)

The possible case for a failure of my_addr() is that when Sock class did not assign a socket descriptor.

In this case, peer_addr() can also fail.

{section: Note for constants}
Don't forget constants that should be adjusted!

MAXMACHNAME : seen in file_transfer_db.c, stores the result of sin_to_hostname.

{section: IpVerify}

[zach] implemented by mostly Todd, and little bit by Zach and Dan.

IpVerify verifies the remote process's ip from the configuration file. There are many lines that are referring to DCpermission. I am bit confused here. I do not understand what 'DCpermission' made for.

{section: Ulrich Mystery}
Ulrich's Userlevel IPv6 Programming Introductionn - http://people.redhat.com/drepper/userapi-ipv6.html

He denotes gethostbyaddr() as an obsolete. However, gethostbyaddr() accepts a socket type as a parameter. (AF_INET, AF_INET6) That means it should work well with IPv6. Why it is obsolete??

{section: Converting Sock}
Sock is not only used by TCP/UDP connection but also used by Unix domain socket (AF_UNIX). Basically, Sock can only create TCP or UDP socket internally but SharedEndPoint and SharedPortClient creates Unix domain socket and calls Sock::assign() to pass the descriptor.

I guess this is broken abstraction since Sock has IP related functions such as peer_addr() or peer_port() which are not available to Unix domain socket.

It seems assign() is only used by these Shared* thing. So maybe we could end up with refactoring it.

{section: What is it?}
TCP_FORWARDING_HOST ?
