>Description:
If you modify /etc/inetd.conf, and change the auth mechanism, then hup
inetd, inetd continues to use the old auth, not the new auth.
>How-To-Repeat:
modify /etc/inet.conf to contain this auth line:
auth stream tcp nowait nobody /usr/local/etc/ident.sh auth
then create this script in /usr/local/etc/ident.sh
#!/bin/sh
ident=`/bin/date +%s`
xxx=`/usr/bin/head -c 11`
echo $xxx : USERID:UNIX:$ident
then killall -hup inetd
then try a telnet to port 113 from another box:
[dan@set:/usr/local/etc/freshports] $ telnet 192.168.0.20 113
Trying 192.168.0.20...

0 , 0 : ERROR : X-INVALID-REQUEST
Connection closed by foreign host.
As you can see, there's no way said script can create that error.
inetd is still using the other auth.
