Dave's questions

Following the tutorial on http://www.waitingforthefuture.org/2009/12/25/compiling-tcpdump-for-tomato-firmware/, I tried to compile tcpdump. I did the compilation on an Intel Pentium 4 2.26Ghz computer running Ubuntu 10.04.

My router uses a BCM3302 V2.9 CPU. However, when I run tcpdump on it, it says "Illegal instruction".

Why does this happen? What other configuration must I do before compilation?

Is it possible to capture wireless packets on my wireless network using sniffers (ie. wireshark)? If so, could you give links that can guide me to do this?

QMail uses the server's default IP as its outgoing IP. How do I change the IP to something else?

I tried the instructions in the following links but they don't work in my case.

Any help will be appreciated.

I want to set up multiple mail servers within one dedicated virtual server in Mediatemple.

For example, my server's primary ip address is 203.156.0.xx. My server has another IP address 203.156.0.yy. The server's outgoing mail server is 203.156.0.xx.

Currently, all domains regardless of which IP address they use have 203.156.0.xx as their mail server. Is it possible that the domains under 203.156.0.xx use 203.156.0.xx for their mail server and domains under 203.156.0.yy use 203.156.0.yy for their mail server?

Any advice will be appreciated.

I have a mediatemple dv server and it has 3 IP addresses. Currently, it uses one of the IP addresses for the mail server. How do I use another IP address? Is it possible to use two of the IP addresses for the mail server?

Sorry, I'm new to this.

I have two servers:

• www.website1.com
• www.website2.com

I have another server www.website3.com which I want to be allowed to send emails in behalf of the first two websites. How do I do this?

I need to edit the hosts file in my (dv) server. However, the file isn't under /etc. Where do I edit it in Mediatemple?

Any help will be appreciated.

I have a PHP script in a Mediatemple (dv) server that uses cURL to post data to a remote website. This remote website also resides in a (dv) server and doesn't have a domain name yet. I can only access it through web preview.

I'm planning to edit the hosts file of the first server so it can do cURL. Is this even possible?

Suggestions will be appreciated.
