fixed Debian bug 536060 (log files are closed after SIGHUP receival) Explanation: When run in daemon mode, first the log files are opened. They get assigned to the file descriptors 3 and 4 usually. Then std{in,out,err} are closed. When SIGHUP comes in, all open files are closes and masqmail reexecutes itself. The new masqmail instance opens the log files at fd 0 and 1 now, but std{in,out,err} are closed afterwards, thus the log files are closed. The fix is to close the log files before std{in,out,err} are closed, in case the log files have higher fds. After std{in,out,err} were closed, the log files get opened again, now.

21 This is the second stab at a small library to interface to the Ident
22 protocol server. Maybe this will work correctly on some machines.. :-)
23
24 The ident-tester.c file is a small daemon (to be started from Inetd)
25 that does an ident lookup on you if you telnet into it. Can be used
26 to verify that your Ident server is working correctly.
27
28 I'm currently running this "ident-tester" on port 114 at lysator.liu.se
29 (130.236.254.1) if you wish to test your server.

34 This library now contains some higher-level routines, as well as a
35 similar test program to test these (lookup-tester).
