Antonio's questions

I have an Apache 2 server and it have several vhosts with similar definition:

<VirtualHost *:80>
    DocumentRoot /var/www/html/host1/
    ServerName host1.loc
    <Directory /var/www/html/host1>
        AllowOverride FileInfo Options AuthConfig
    </Directory>
    ErrorDocument 404 /index.php?error=404
</VirtualHost>
<VirtualHost *:80>
    DocumentRoot /var/www/html/host2/
    ServerName host2.loc
    <Directory /var/www/html/host2>
        AllowOverride FileInfo Options AuthConfig
    </Directory>
    ErrorDocument 404 /index.php?error=404
</VirtualHost>
...
<VirtualHost *:80>
    DocumentRoot /var/www/html/hostN/
    ServerName hostN.loc
    <Directory /var/www/html/hostN>
        AllowOverride FileInfo Options AuthConfig
    </Directory>
    ErrorDocument 404 /index.php?error=404
</VirtualHost>

I would like to customize page 404.

The problem is that when I try to test 404 page in any of the hosts, I can see the page from the very last vhost. What could be wrong with my config?

I've got a strange problem. I can not allow apache to connect to database at my CentOC 6.4 box:

[root@centos6 ~]# setsebool -P httpd_can_network_connect on
Killed
[root@centos6 ~]# sestatus -b | grep httpd_can_network_connect
httpd_can_network_connect                   off
httpd_can_network_connect_cobbler           off
httpd_can_network_connect_db                off

I watched log file, but there was no log messages:

tail -f /var/log/audit/audit.log

UPDATE:

There are some information in /var/log/messages:

I have a subnet of computers connected to Internet through a router (which could be a HTTP proxy as well).

My goal is to change URL parameter for a one single URL.

If users go to http://www.google.com/ or to http://www.google.com/?hl=en, in both cases they should see content from http://www.google.com/?hl=fr

Is it possible to do this using url rewriting in apache config? What other approaches could become the easiest way to achieve the goal?

Update: google.com is used just an example, that's not the case.

I installed wordpress to CentOS from EPEL:

yum install wordpress

And it can only work if I manually disable SELinux. Otherwise I see this error:

PHP Fatal error: date(): Timezone database is corrupt - this should never happen! in /usr/share/wordpress/wp-includes/functions.php on line 105, referer: http://www.myblog.com/wp-admin/

ls -Z /usr/share/zoneinfo

drwxr-xr-x. root root system_u:object_r:user_home_t:s0 Atlantic
...
(many lines skipped)

How can I fix this?

I installed wordpress 3.5 to CentOS 6.3 using command:

yum install wordpress

and started httpd. Now I can see the following error in apache log:

PHP Fatal error: require_once(): Failed opening required '/usr/share/wordpress/wp-includes/class-simplepie.php' (include_path='.:/usr/share/pear:/usr/share/php') in /usr/share/wordpress/wp-includes/class-feed.php on line 4, referer: http://www.mycompany.com/wp-admin/

I guess that that's because of SELinux:

ls -Z /usr/share/wordpress/wp-includes/class-simplepie.php 
lrwxrwxrwx. root root system_u:object_r:usr_t:s0 class-simplepie.php -> /usr/share/php/php-simplepie

drwxr-xr-x. root root unconfined_u:object_r:user_home_t:s0 SimplePie
-rw-r--r--. root root unconfined_u:object_r:user_home_t:s0 SimplePie.php

I wonder if there is a way to let it work without disabling SELinux?

I have two CentOS hosts. The first is NAS and the second one is a diskless SMB server. The NAS server share folder via NFS and secure Ethernet connection with SMB server. SMB server shares content to Intranet, WiFi, etc.

When I run this command, I've got some trouble:

[root@smbserver ~]# chcon -t samba_share_t /mnt/distr/
chcon: failed to change context of `/mnt/distr/' to `system_u:object_r:samba_share_t:s0': Operation not supported

I tried to mount this share with option in /etc/fstab:

nasserver:/mnt/distr /mnt/distr nfs context="system_u:object_r:samba_share_t:s0" 0 0

But this also does not help.

Is there a way to share via SMB a filesystem mounted via NFS without disabling SElinux?

Update fails with error code 800B0001 after installing fresh instance of Windows 7 Ultimate 64bit.

Note: the system is connected to WSUS.

Is there a way to fix this?

I have two servers connected via Gigabit Ethernet. One is iSCSI target, the second one is initiator. When I run mkfs.ext4 at initiator, after a while disk IO slows down critically in target. In the target host I can see the following in syslog:

Is there a way to tune target host to avoid these timeouts?

I'm using some kind of Whitebox and my hardware drives are not recognized under Configuration -> Health Status

And which one is better for connecting two linux machines?

I try to monitor MySQL database:

but I've got unexpected error:

What's wrong?

I'm installing Oracle Database 10g Release 2 (10.2.0.4) for MAC OS X on Intel x86-64

I have Mac OS X 10.6.7, running at Intel Mac.

When I start installing, I am faced to the following error:

Is there a way around this problem?

I have just created ISO using these instructions:

Creating an iso file in Linux

How can I mount this iso image that was created?

I just wonder if there is a way to use SSL certificates or PGP keys for signing my email.

At the moment I have to setup S/MIME in Outlook (or another thick client) to send signed messages via SMTP. It works for me, but I'm looking for a way to do the same using GMail's web interface.
