I mean the usage of fdopen, fgets, fprintf etc. on the socket instead of read/write in rfc931.c. At the same time, the "original" socket descriptor is heavily used. But then, i looked at the version 7.6 from Wietse Venema, and the stdio stuff is there, too. What is new in socket_wrappers is the strange :) stuff with safe_select. On my machine it hangs in the second safe_select until it times out. I did not have the patience to dig deeper. 'try-from' is used to print out tcpwrappers' idea about local and remote hostname, ip-address, user (this is what the identd is used for), etc. It is used like "rsh tcpwrappers-host $prefix/sbin/try-from".
