[Dorset] Apache 2.4.2
Is there any experience of Apache 2.4 in this area? As part of an upgrade and installation on a new PC, I installed Apache 2.4, but cannot get it to display .cgi files produced by my APC UPS that is managed by apcupsd version 3.14.8. On an earlier PC, I had Apache 2.2, which displayed the data from the .cgi files, but 2.4 has a very different httpd.conf file, and no matter what permissions I relax, I still get the message Not Found The requested URL /var/www/cgi-bin/multimon.cgi was not found on this server. I have checked that current data is being generated in the multimon.cgi file. Of course, I could always wimp out and install the previous version, but that's not what it's about, is it?

That should pretty much work out of the box? There is plenty of advice if it is not working here: http://httpd.apache.org/docs/2.4/howto/cgi.html If the configuration has the standard script alias then that should work *unless* the permissions on the cgi file do not include execute access for www-data ?

It might help if we had the permissions of the CGI file in question and
every directory above it, e.g. assuming it was the file `foo' then set f
to its full path from root and then run this while loop; "$" is my
shell's prompt.
$ f=/home/tmp/1348682210.641081587/foo
$
$ while [[ $f ]]; do ls -ld "$f"; f=${f%/*}; done; ls -ld /

Ralph, that is very cool. It has just gone into my .bashrc as an alias! I
had not come across that bash function ${f%/*} before.

There are various substitutions shells like bash(1) provide on variable
expansion that avoid having to kick off a sed. Here's some variations.
$s foo,bar,xyzzy
${s#*,} bar,xyzzy
${s##*,}xyzzy
${s%,*} foo,bar
${s%%,*}foo
${s/bar/prohibit} foo,prohibit,xyzzy
${s/o} fo,bar,xyzzy
${s//o} f,bar,xyzzy
${s//[aeiouy]/V}fVV,bVr,xVzzV
`#' and `%' are mnemonic in that `#$%' are on `345' on the keyboard with
`#' matching at the start of the variable and `%' matching at the end.
`/' is obviously traditional at this point, being the common `start of
pattern' character in ed(1)'s `s' substitute command.
The easy way to get a refresher is `man bash' and search for `##'.
Note, the pattern to search for isn't a regexp, more a glob.
Cheers, Ralph.

An expanded version of the above. It takes multiple arguments and cuts
out the repetition in the output.
$ cat lup

(`lup' just because I already have `l' that does `exec ls -l "$@"'.)

Cheers, Ralph.
It must be some sort of permission problem. I executed the following
$ cd /var/www/cgi-bin
[graeme@handel cgi-bin]$ ./multimon.cgi
which produced a whole lot of HTML.
I put that into a file with .html suffix and opened it in Firefox and
got the expected display.
I tried to do the same with upsstats.cgi, and in the generated HTML I
found the line
Access to host 127.0.0.1 is not authorized.
The most recent line in the access log is
127.0.0.1 - - [28/Sep/2012:13:06:58 +0100] "GET
/var/www/cgi-bin/multimon.cgi HTTP/1.1" 404 226
There is no entry in the error log since 13:00 hrs yesterday.
Changing the permissions on /var/www/cgi-bin had no effect.
What bit of software processes a .cgi file?
Thanks for your interest,
Graeme

So that's two distinct problems? One is having Apache serve up any CGI output from that directory and the other is specific to upsstats.cgi. > The most recent line in the access log is > 127.0.0.1 - - [28/Sep/2012:13:06:58 +0100] "GET > /var/www/cgi-bin/multimon.cgi HTTP/1.1" 404 226 > There is no entry in the error log since 13:00 hrs yesterday. > Changing the permissions on /var/www/cgi-bin had no effect. > What bit of software processes a .cgi file? mod_cgi in Apache arranges for it to be run when it receives the HTTP request from the web browser. You're probably already reading through these pages anyway, but in case you don't have some of them... http://httpd.apache.org/docs/2.4/howto/cgi.html http://httpd.apache.org/docs/2.4/mod/mod_cgi.html http://httpd.apache.org/docs/2.4/mod/mod_alias.html#scriptalias ScriptLog in mod_cgi may be useful. Perhaps show us the section of the conf file you've settled on for /var/www/cgi-bin?
