OpenSSH developers, I have removed the fixed, arbitrary limit on the number of ListenAddress allowed by using realloc to dynamically expand listen_socks as needed. This completely removes MAX_LISTEN_SOCKS from the source. I made this change on the version of OpenSSH shipped with CentOS 5.2, version 4.3p2. Please see the attached .c file and .diff file. Please add these changes to OpenSSH

In sshconnect.c there are two global variables for server_version_string client_version_string. These are used just in a few functions and can easily be passed as parameters. Also, there is a strange construct, where their memory is allocated to the global pointers, then copies of these pointers are assigned to the kex structure. The kex_free finally frees them via cleanup of the kex
