I installed the Centos 5.5 and after the Xen. After I put a virtual machine named VM01.Initially it worked properly, I tried everything and it worked.When rebooted, I had problems with the network.I have two network cards eth0 and eth1, but eth1 does not have any ip and I use only eth0.The error that appears is:
vif0.0: received packet with own address the source address

how to change ip address on centos 5.3 ?i could not search the file such as "interface" ,
View 3 Replies View RelatedI 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.

I'm stumped here as it seems like after an update etho:0 has assigned itself 2 x IP Addresses. I don't understand how this happened or how to fix it so some help would be great as I cannot access cPanel while it's like this or my sub directories.Here is a print of ifconfig

View 5 Replies View RelatedI 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.

My 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?

One of our client having issue with the qmail. The issue is if any one send email to abc@ourdomain.com (abc@ourdomain.com the email address which is not exist) it should send failure notification i.e."email does not exist" to the sender. The qmail server is not notifying that email address does not exist.
View 1 Replies View RelatedI am having a problem getting a wireless network connection on my DELL laptop running CentOS 5. I have no problem getting a wireless connection when the laptop is booted in Windows XP. I also don't have a problem when booted under CentOS 5 and there is no authentication setup on the wireless router. I only have a problem when I setup authentication. The router wireless log shows the PC connectinng, authenticating, and succeeding authentication.I am using the Broadcom Hybrid-wl wireless driver.
View 19 Replies View RelatedI am a developer, not a network admin - sorry if this ia dumb question. I need to test an application on CentOS 55 64 bit. The instalation went fine and initially I let DHCP work its magic. The router IP address ia 192.168.0.1 and all other VM's I have are granted dynamic ip address on this range (i.e. 192.168.0.x). However, the CentOS vm got an IP address that looks like it belongs on a different subnet :192.168.1.1
The VM (vmware desktop) network setting for this VM uses "Bridged: Connected directly to the physical network". I can ping the host (Windows 7 64 bit) and the host can ping it (it been the VM) - but no other computer on the network can see it. To make things easier, I changed the network configuration to use a static IP address. Here are my configuration files:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:83:4B:A4
ONBOOT=yes

i have a small issue, to make our network more secure, i now require outgoing email to require authentication. Now the problem..i have a automated mailer that does not have the option to authenticate. is there a way to allow a certain email address or the local network to send out without authentication? If i cannot do this for a single email user to allow them through with authentication, how would i remove the authentication paramaters in the postfix smtp..

View 2 Replies View RelatedI am having (seemingly) random trouble with my wired network ever since I installed Lucid. I have no problem getting an ip address from dhcp. However, randomly the computer will boot and although I have an ip address I do not receive any responses for pings on the network nor can I browse the web. If I sudo /etc/init.d/networking restart a few times (or reboot) it will start working. However, restarting the networking services (as mentioned above) again will cause me to no longer receive responses for pings or browse the web.
Furthermore, I have never been able to successfully ping if I manually set an ip address. I have un-installed network manager and I am using /etc/network/interfaces to configure the network. Using Lucid Lynx 64bit on a Dell Precision. I have pasted below the output of a few working commands. When I switch between static ip and dhcp I am commenting/uncommenting the lines shown in /etc/network/interfaces.
