Gerard,
13:13:33 ERROR 500: Update option unavailable: Can't write to
/var/apache2/2.2/cgi-bin/pca-proxy.cgi.
...
The server is configured as follow:
r...@www2:/var/apache2/2.2/cgi-bin# cat /etc/pca-proxy.conf
...
update=auto
That's the problem. If "update" is set to "auto", pca (in that case
pca-proxy.cgi) will try to update itself, and therefore must be writable
for the user who runs pca. This would be "webservd" here.
does it mean that apache need to write the file pca? That seems to be ok
if i chmod pca* (chmod +w pca*)
You could change ownership for pca-proxy.cgi to webservd and make it
writable for that user only (e.g. mode 755). Or remove the
"update=auto". As changes or updates to the proxy functionality are
rare, you won't miss much with auto-update disabled.
Martin.
