Subject:	strace on inetd (was RE: bash failed to initialize on
	telnet/rsh/ rlogin server)

I can't get strace to give any output against inetd. (which I'm trying to
trace with -f to catch the startup of login.exe)

Here's what I tried:
$ ps -a
      PID    PPID    PGID     WINPID  TTY  UID    STIME COMMAND
     1636       1    1636       1636    0 13721 12:32:03 /usr/bin/rxvt
     1576    1636    1576        604    1 13721 12:32:03 /usr/bin/bash
     1252       1    1252       1252    ?   18 12:42:57 /usr/sbin/inetd
     1796    1252    1252       1796    ?   18 12:42:57 /usr/sbin/inetd
      580       1     580        580    4 13721 13:44:44 /usr/bin/rxvt
     1244     580    1244       1356    5 13721 13:44:45 /usr/bin/bash
     1732    1244    1732       1604    5 13721 13:46:40 /usr/bin/ps

$ strace -p 1252 -f all
<<returns immediately>>

$ strace -p 1252 all
<<returns immediately>>

$ strace -p 1252 -f
<<returns immediately>>

$ strace -p 1796 -f all
<<returns immediately>>

$ strace -p 1796 all
<<returns immediately>>

$ strace -p 1796 -f     
<<sits at command line with no output, even during sucessful 'telnet
localhost'>>
<<Ctrl+C gets command prompt, but kills both inetd's>>

diverting output to a file with the -o option has no effect.

leaving off the -f has no effect, either


Are there more complete instructions to strace besides --help, the Cygwin
user guide, or winsup/utils/utils.sgml (all essentially the same thing)?

Thanks,
Chris
