I've been trying to research this, but I don't really understand IP routing and it's bugging me that I can't fix this problem. I have a dedicated server (fedora core 7) with 3 IP addresses on the same eth0 interface. On the default IP address 62.193.226.127, there is some routing problem because I can't connect from the server to some other sites. Using one of the other IP addresses, like 62.193.252.129, I can connect fine. Additionally this address is better for sending mail because it coincides with the main domain name from which the mail is sent.My question is: how can I configure networking so that outgoing traffic from the box goes via 62.193.252.129?
I have 3 ip address on my VPS and I need to change exim configuration to listen only on one ip address. VPS have WHM and Cpanel installed.I changed in exim configuration interface to my ip.
I need to know what the Iptables "code" is to change the outgoing/Incoming IP for port 53 (DNS). I'm running CentOS on a dedicated server. I very familiar with Putty and SSH. So I don't need much details, I just can't figure this out. I asked my server providor but they deleted my ticket and didn't answer me.I tried this but am not sure if this correct of working?
I am testing my setup which will have 2 public servers. HTTP & MAIL both with reverse DNS established.
www.mydomain.no -> xxx.xxx.xxx.034 -> internal name server mail.mydomain.no -> xxx.xxx.xxx.035 -> internal name mail Both addresses are on the same NIC with 34 being the main address.
The system work fine except one thing. The IP address mail sends out from is the Firewall Address _FW. I can see why as the default gateway set on the mail server is the FW_IP (The main gateway ip)How can I get the MAIL server to send through it's own public IP.I understand I can change the Firewall public IP to that of the Mail server and that would cure the problem for now. If it's possible I would like to learn a little in the process.
I just set up a new router for our home office. I've enabled traffic logging, and I'd like to have the logs emailed to me. However, in order to configure email-notification, the router needs and outgoing mail server. Forgive me, but I don't really understand the terminology being used here. I've googled this a bit, but I'm not sure I now what "outgoing" vs "incoming" mean in the context. I tried using my gmail account as the outgoing mail server (smpt.gmail.com) but it requires TTLS encryption, and there's no option for that on my router.
So I figured I'd setup a simple mail server on my local network. I have a dedicated server machine, so I'd just configure a mail server there. But I got stumped at the first input box (in the yast module):"Outgoing Mail Server".That's what I wanted to use this server for. What is this "outgoing mail server"? I understand it in a normal emai context (I think) but this is confusing me. I've read through the HowTo on the openSUSE wiki, but it still doesn't answer this question.Isn't there some way to have a simple, local mail server (without MX records and the like) so I can send email from a local machine?
Our organization has several external IP addresses. I am behind 2 layers of NAT and the servers choose which IP address to route my traffic to. Can I specify which IP address to use when finally leaving the organizations network. I know that source routing can be done in IPv4 by adding some options in the header. But can I configure my PC to add these options automatically. I have both a Windows and a Linux Machine.
I just discovered View > "All message headers" in the Evolution email client and am quite concerned that all my out going emails contain my personal IP Address. I know that this is standard email protocol but i'm wondering if it is possible to hide or modify this header information? Or would i be better off using a webmail client?
I have a Linux IPTables firewall on Centos 5.3.It has one physical interface to the internet and 2 internal interfaces to a DMZ and TRUSTED zone respectively.There are 10 virtual interfaces linked to the physical public interface.Emails are being sent from my server in the DMZ out to the internet, but it is being shown as coming from the firewall IP address.It must show as coming from one of the virtual interfaces.
I have setup mail server on Ubuntu 9.10 and it's is working fine.I am using Webmin to addministrate my mail server.My Ubuntu server name abcs.I send a test mail from Wedmin for user gom.Why it keep adding InfoNet. What I would like is setup as gom@abcs.com.
Here's a good one. Using KMail when I open a new message and click on 'Select' it doesn't seem to be giving me all of my contacts from KAddresbook. Just ones I have sent mail to. That's under the all contacts tab. If I try to select default address book it shows nothing.
How do i type in an address into Nautilus (default file-browser in Gnome DE)? By default it shows me the folders as buttons instead of a typable url-type space, how do i change it to a white space i can key-into?
Some people may need to change the mac address of their ethernet network cards. This can be easily done with fedora with command line. Just follow the steps below:
1. Log as root on a textual console (ctrl+F2) or through "su -" command in your console
Here, eth0 is the ethernet interface of your system. The mac address is put in red.
3. Change your mac address using the following syntax
ifconfig eth0 hw ether 00:18:8BA:7E:90
The new value (in green) must be hexadecimal
4. if you have a dhcp server that distributes the adresses automatically, then request a new adress for your eth0 interface
[root@localhost ~]# dhclient eth0
5. Now, your interface is up and have a new mac and IP addresses. This feature may be useful if the network administrator ban you according to the mac adress, for example .........
I have a dual-boot laptop where both are configured as clients for bacula (backup software). Since it is a laptop and it gets used outside the network where the backup is done, I can't just assign a static IP and be done; it really needs to accept an address via DHCP.
Changing the MAC address is easy:
Code:
But if you do this manually, then you'll need to restart your connection. I don't want to do that, I want the laptop to just come up with the correct address in the first place because one day I will forget to change it and the backup system will be very confused (and I will be very sad when I find myself needing that backup).
The solution is to run an init script prior to starting the network. Below is the script I am using, with someone marginal comments. It is based on the network script in /etc/rc.d/init.d, heavily edited. You will need to add one parameter to your ifcfg-ethX configuration file to set the desired MAC address. That parameter MACADDR does not seem to be used by any of the init scripts. You will find it in some of the scripts in network-scripts, but it is not used as an input parameter, but rather set by querying the NIC, thus this use does not conflict.
I've just reinstalled F14 with KDE rather than Gnome and I'm finding that I'm unable to assign a static IP address to my wired connection.
KDE automatically connects via DHCP, but when I go into KDE's network manager, the eth0 connection isn't listed. In fact, no wired connection is listed. If I manually add one with the correct settings (including a static IP), it switches back to DHCP upon rebooting.
How can I get around this? Should I install the networkmanager-gnome package?
When I create virtual ethernet interface and do a ping -I <v_int> <host> the outgoing address is the one of the physical interface and NOT the virtual interface.Is there no chance that trafic will go out with virtual interface address??Incoming trafic is done well i.e. responds to the virtual interface have the virtual address.
My problem is that I have 2 modems and want to check both default gw behind the modems. If I do a "normal" ping both are reachable over default route even the modem which is not the default route will not work because ping goes over the working modem.So I have 2 routing tables and want to route the virtual interface to one modem the other to the other modem
I have just changed my gateway address,now I can access internet with my browser but unable to run add/remove software as it says no network connection available,system updates are not working as well. What should I do make these working?
I can only get so far and then I find myself staring at the menu.lst (/boot/grub) in gedit. It looks nothing like the menu.lst in Linux Mint 7 and I know that tampering with the menu.lst could spell disaster. So how do I go about changing my default OS to Vista? I have been tinkering with distros for quite some time now but still not a pro.Take a look at what I got below.

Whenever I use lpr on the command-line to print a text file, it uses DejaVu Sans Mono as the font. Is there a way to change this? I'd like to use Terminus as the font instead. I found that CUPS uses Courier as the default font for text files, so somewhere Courier is being aliased to DejaVu Sans Mono, and I have no idea where.
I'm somewhat of a n00b. I have a dual boot machine running XP and Fedora Core 14. I like my default boot always to be XP. Right now, XP is default BUT every time there is an update to Fedora, it will change the default to Fedora. I now have to edit grub.conf to boot from xp again. Is there a way to make xp always as the default even after an update?
I installed Fedora 12 LXDE spin and its default session was LXDE. Then I downloaded XFCE and tried to change the default session of GDM to XFCE. I edited ~/.dmrc and /etc/sysconfig/desktop but this didn`t change anything. I was unable to find where GDM stores its default setting.
Is there any way to change GDM default session?
And more important: is there any way to make GDM to store different default sessions for different users?
How do I change my default keyring password in F11?
The instructions from here no longer work:
Code: $ yum search gnome-keyring-manager Loaded plugins: dellsysidplugin2, fastestmirror, refresh-packagekit Warning: No matches found for: gnome-keyring-manager No Matches found Longer story:
Somehow I got my keyring and login passwords out of sync. I went to change my login password using passwd on the terminal. I meant to change it to (let's say) "abcdef" but typed "abcdfe" twice. Realizing my mistake I tried to used passwd a second time to change it to "abcdef", but passwd complained that the new password was too similar to the old. So I used "su -c 'passwd myusername'" - I was able to change my login password but I guess this did not update my keyring password. I've tried changing my password using passwd as myself (not root) to something completelydifferent, but my keyring password remains the first password (e.g. "abcdfe").
my last Fedora installation, the pulseaudio source is wrong. The default sink is:

When I change it on desktop login as regular user to the right thing, then log out or reboot, I have to change it again when I log back in again. This is with an Audigy2 card, and onboard audio chip. I switch between the two for various reasons.
I'm trying to change the desktop to KDE so that it's persistent across boots. I did the usual thing of adding /etc/sysconfig/desktop and adding the appropriate parameters, but for whatever reason, whenever I reboot, it still loads Gnome. Now here's where it gets annoying: I can switch to runlevel 3, type startx, and then it will read /etc/sysconfig/desktop and load KDE properly. I've been banging my head against a wall over this one. Where is the call made to start gdm? I think I'll probably wind up changing the default runlevel to 3, but I'm still curious as to why those scripts are not executed on boot.
