CentOS 5 Server :: All Emails Go To One Address?
Apr 6, 2011I am working for the first time on a dedicated server with CentOS. I have sendmail and postifx installed and I realized all the emails send by the server are redirected to my own private address.
For example if I want to send an email to "luc@test.com", I will receive it in my box (ex "paulin@gmail.com")... I also receive in my box the logwatch which should be send to root@serverblabla.live-servers.net
That is very strange and I really don't understand what does that.

CentOS 5 Networking :: DGE-530T Will Not Get IP Address From DHCP Server
Aug 6, 2009I am attempting to get this network card running under CentOS 5.2 but have had no luck. Some sites say to use the sk98lin driver, others the skge, which I can't find at all. I have tried multiple versions of the driver in rpm but none seem to work. The card shows under the network manager but will not get an IP address from the DHCP server.
Here are the outputs for this card.

CentOS 5 Server :: Sending Logwatch To External Mail Address?
Nov 4, 2009My ISP blocks outgoing email if it does not login properly with a valid account. I successfully configured sendmail to use SMART_HOST and confAUTH_OPTIONS with confAUTH_MECHANISM set to LOGIN PLAIN.
It successfully sends email because I tested it with evolution sending through 127.0.0.1, but I need to specify myacount@mydomain.com as the email address for root.
But it doesn't work for logwatch because it sends as from root@localhost.localdomain, and my ISP's smtp server rejects it. The message I get back in root@localhost account is the following:
----- Transcript of session follows -----
... while talking to smtp.mydomain.com.:
>>> MAIL From:<root@localhost.localdomain> SIZE=581 AUTH=<>
<<< 550 5.7.1 Client does not have permissions to send as this sender
554 5.0.0 Service unavailable
I thought that I should masquerade all emails from this domain, so I configured sendmail as specified in [1] section "24.3.1.4. Masquerading", but it doesn't work. It seems that masquerading in sendmail is broken or something is wrong in the documentation.
[1] [URL]
I have sendmail 8.13.8-2 and centos-release-5-4.el5.centos.1.
Is there a way to specify the "From:myacount@mydomain.com" in logwatch ? or Is there a way to make it work the masquerading in sendmail so I can masquerade everything as coming from a specific account?

Whenever I am trying to change the webroot of the httpd server, it usually say "directory doesn't exist". whereas which can't be the case as it is home directory of the user.
To achieve this, what Do I need to do?
The second issue, I am facing that whenever I am adding new directories to public_html folder, it is not accessible. as the error page 404 is shown. I have changed the permissions to 0705 and ownership is also transferred to other user. What else is required to make new directories accessible by the web?

Server :: OpenVPN Range Address / When Change Static IP To Dynamic IP In Config File OpenVPN Didn't Work?
Feb 13, 2010I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.
