General :: Windows - Selecting Which IP Address To Use For Outgoing Requests From Behind A NAT
Mar 12, 2010
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.
My Firestarter logs show periodic outgoing connection attempts to IP addresses in countries such as Malaysia, China, Russian Federation etc... Fortunately, Firestarter appears to be blocking them. I suspect these are not good and want to find out exactly what process is initiating these outgoing connections.
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 am trying to send a multicast stream out from a Windows XP computer to my FC12 computer. I am using VLC for both the stream and the receive end of the process. Its version is 1.1.0-pre1 if that helps.As of right now I've used Wireshark to detect network packets, and I am unable to see any IGMP requests from the Fedora's IP address, whereas when I try to initialize a receiving stream on my Windows XP computer, I can see IGMP packets where appropriate. So the issue clearly lies with either VLC in Fedora, or Fedora itself, but I can't figure out how to narrow it down any further.
If it helps, I AM able to stream FROM my Fedora computer TO my Windows computer. Additionally, I am UNABLE to stream from my Fedora computer back to my Fedora computer (locally), despite being able to do that on the Windows side.
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 had windows 7 on my system and now i installed debian squeeze but grub does not show my windows 7 in menu for selecting how could repair this problem?
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?
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 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 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 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 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.
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
Menu sometimes will stay visible on the desktop or on top of other windows after selecting them. To fix it I normally log out then log back in. Its been doing it for a few weeks. I install lots of eye candy/themes etc and have Avant, docky and cario-dock and think it be may some eye candy I installed, not sure. I have a ATI graphics card thats been tested by the distro.Using the latest 10.10 as I update security and recommended updates via update manager.
I've got this old computer. PII processor, 4gb HDD, I forget how much ram but the mobo is an AOpen AX63 pro [URL].. The machine still runs great. I just finished cleaning all the connections with alcohol and putting the thing back together. I've got Ubuntu 5.10 on it right now, but with so little in the way of system resources, I want to get something more scaled down on there. Googling hasn't resulted in anything really useful.
So, does anybody know of a scaled down distro aimed at old computers? Obviously something current would be great (I considered trying to find a netbook distro and use that, but I don't know if there would be any issues using that kind of thing on a desktop.) but I'd be willing to use an older distro if I need to. I really just want to use it as a writing machine, with maybe some basic internet access.
i got given an old IBM think pad R40 laptop with a broken HDD and im looking for a linux distro for it, its got 128 mb of ram and a mobile P4 - M 1.80ghz processor all im gonna use it for is basic word processing/taking notes in the field etc. but i would like to have a reasnoble GUI ive tried Puppy, DSL and SLITAZ but their GUI's are rather crude.
I've been using Linux for about six years now, and I joined this website hoping to learn more about Linux, keep updated with Linux news, others less experienced than me; I spend so much time on Reddit I rarely remember there's a whole Internet how there and I've yet to really visit this website since I registered. I'm posting this in the newbie section because the problem I'm having feels like it probably has a simple solution, but I don't what to do. If this forum is inappropriate, I suppose a mod could move it?
Anyway, upon highlighting a link in either Firefox 4 nightly or Chromium, I get this pop-up menu: [URL](copy paste and remove the space between the h and the t - and yes, this is a "screenshot" taken with a camera, as this menu seems to inhibit the functioning of the PrintScreen key for some reason) I do not need to click - as soon as a URL is highlighted, the menu pops up, forcing me to click away in order to cancel the menu. At first I assumed it was a Firefox thing - it happens in both 3.6 and 4 Nightly - so I began checking all of my add-ons (only 4) and plugins to see if I have some plugin causing this. Nothing seemed to be.
When I switched to Chromium, I quickly realized the same thing happens in Chromium, as well, so it's independent of what browser I'm using. This leads me to believe it's some package I have installed (apt-get, I'm using Linux Mint on this laptop, and on my other computers, which are running Arch, I do not encounter this in either Chromium or Firefox4) that's causing this, so if someone could just identify what package it is I can remove it. Or maybe my assumption is incorrect and there's something else that leads to this popup, but either way, it's really annoying and I want it gone!
I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.
Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.
So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.
I don't understand why this is so difficult.In the old days, there was lpforms which allowed some formatting. CUPS did not see fit to implement this into it's lp package.cgi-...-cgi?lpforms+1In the old days, lpr allowed you to select a font in the command line with -1=fontname. CUPS did not see fit to implement this into it's lpr package.htmIn the old days, printers had fonts installed on them that you could access. Modern printers don't seem to have this. So now I still need to be able to select a font when I print certain text files from the command line but it seems this is impossible. I've been working with instances and lpoptions, which allows me to do a lot of other things I need like orientation and margins and even set the font size, but I still cannot choose a font other than the default.
I want to block all the outgoing ssh form my machine, i.e my machine will not be able to ssh to any outside machine using iptables. The distro is RHEL, I added the following entry in the iptables but unfortunately it didnt worked, -A OUTPUT -p tcp -m tcp --dport 22 -j DROP
I am trying to load vmware server. When running vmware-install.pl it asks where to load the bin files. Default is /usr/bin. Cool with me, so I accept then get the error: "There is insufficient disk space available in /usr/bin. Please make at least an additional 5924k available or choose another directory."
Ok, so in my searches, most cases people actually do have a full disk. I have 30gb free. Another post somewhere stated it could be the file system used, so I tried different file systems. Now I am back on etx3. What's odd is when I blow away the OS and reload and try to install VMware again, I get a different number to be "freed" in the error. Choosing another directory only yeilds a different disk space request.
How do I check/setup that only the server can send mail (maybe by IP or hostname)? I have a debian server that sends mail through the PHP mail() function with no problems. The server uses sendmail. My concern is how do I make sure only the server itself can send mails through that server. Because it would be bad if spammers would use it as a relay server.
I'm using an up-to-date installation of Squeeze with the default Gnome desktop and am trying to print. My knowledge of configuring printers is very limited if it even exists. Since a friend of mine is able to print from her Ubuntu computer, my plan is to copy her. Here's how she does it. She goes under System->Administration->Printing on the desktop. Then a window pops up titled "Printing" that lists various printers that are supposed to exist. It's possible to add one by selecting Add->Printer. It asks for the root password and then a new window pops up titled "New Printer" which has a subwindow called "Select Device" In my case, the "Select Device" window has the following options to choose from:
- AppSocket/HP JetDirect - Internet Printing Protocol (ipp) - LPD/LPR Host or Printer
In her case, she has an extra option called "Windows Printer via Samba". This is the option that she uses. The other options don't seem to work for her. I'm assuming that I just need to install some package in order to make this option magically pop up for me. Does anyone know what package this may be? I currently have the packages smbclient, samba-common and samba-common-bin installed..........
I'm learning about the HTTP protocol and I'd like to know if there's a tool I can use to input a HTTP request I have created myself that will output the raw response. I've had a look at cURL and wget but they don't seem to have an obvious option to do this. For example:
