Re: Apache config problem .. please help
Anyway, all this started from an attempt to access env. vars from legacy scripts running under registry. What is the easiest way to get env. var access without the accompanying performance penalty that mod_perl documentation talks about? If you need to have your scripts run unmodified, have PerlSetupEnv Off in all sections that you don't need to access the CGI env vars, and have it On only in those Locations that run legacy scripts. http://perl.apache.org/search/swish.cgi?query=PerlSetupEnvsbm=SecEsubmit=search __ Stas BekmanJAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide --- http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com
Apache config problem .. please help
I made a simple mod_perl change to the config and when restarting Apache I got this error: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:2250 no listening sockets available, shutting down /usr/local/apache/bin/apachectl: line 87: 16512 Segmentation fault $HTTPD $ARGV I then backed out the change and retried, got the same error. Any clues?

That isn't permitted. But you shouldn't be getting segmentation faults in that case so something else is probably wrong too. Did you build from source? Did you follow the instructions in the Guide? Linux? 1.3.27/1.27? DSO? Maybe you can post the information requested in the docs? 73, Ged.

httpd was not running and I have been running Apache 2x with mod_perl 1.99x for over two months now. It started with a problem I traced to env. var $ENV{HTTP_ACCEPT}. I figured out that I needed PerlOptions +SetupENV. So I added this, stopped and tried to start Apache. That's when I got this shock.

There has been no change to Apache httpd.conf other than the addition
of PerlOptions +SetupEnv which I commented out anyway.
How can I get a list of ports being used so I can kill the processes? As
far as I can tell httpd is not running. The IP is 208.179.25.28
I dont see any apparent signs of hacking either.
RE: Apache config problem .. please help
You can use
netstat -a
to list all the ports in use--look for your configured port or 'http'
you might wanna try
ps -ef | grep http
to search for a process not in top's display (can you see all? Try
setting n=100 and expanding xterm (if using one)).
If 'ps -ef | grep http' returns nothing check to make sure your PID file
isn't still there. Most likely /usr/local/apache/logs/httpd.pid . If
it is there and you're sure httpd's not running remove the file and try
/usr/local/apache/bin/apachectl stop
/usr/local/apache/bin/apachectl start
good luck,
bill

Re: Apache config problem .. please help
I know this is not of much help, but I have had situations where a badly terminating process would prevent subsequent processes from using that port. on windows, i never found a solution other than to reboot. on solaris 7, i never found a solution other than to wait 8 minutes. I did some reading and found socket inet options to change how such programs bound thge port so as to allow others to use it in more friendly a fashion but such a change wasnt possible with the process in question. -- gedanken

As I said, there may be more wrong than just what's obvious. It looks like the obvious explanation that another Apache is running is not the right one. At the risk of asking questions I wouldn't have to ask if you'd posted the information I asked for, why port 2205? That's not what I'd expect to see, but without more information I'm groping about in the dark. What's trying to use that port? MySQL perhaps? Why not stop it first, or change the port that Apache is trying to use, or the port that whatever apachectl is trying to start is trying to use, or... As far as I can tell httpd is not running. The IP is 208.179.25.28 c2h5oh:~$ ping 208.179.25.28 PING 208.179.25.28 (208.179.25.28): 56 data bytes 64 bytes from 208.179.25.28: icmp_seq=0 ttl=236 time=389.6 ms --- 208.179.25.28 ping statistics --- 2 packets transmitted, 1 packets received, 50% packet loss round-trip min/avg/max = 389.6/389.6/389.6 ms c2h5oh:~$ telnet 208.179.25.28 80 Trying 208.179.25.28... telnet: Unable to connect to remote host: Connection refused Looks like you're right.

The problem is resolved. Unbenownst to me - I need to investigate this - the Listen IP:port line in Apache had the wrong IP address. I really dont know how this happened. The number is so different yet syntactically correct to be a keystroke error. Thanks everyone for pitching in. For one I can now use ' netstat' utility to check ports being used,. Thanks Ged! I keep talking to my corporate IT people about open source , and they constantly ask me 'who will support it? what do they get out of it?' . I can not even begin to explain to them the 'connectedness' across the 'net. Should people always measure everything in terms of money? Anyway, all this started from an attempt to access env. vars from legacy scripts running under registry. What is the easiest way to get env. var access without the accompanying performance penalty that mod_perl documentation talks about? Regards
