I have configured CentOS 5.4 as a router/firewall (iptables) as such, and it is working fine:
eth0 - Public IP/Intenet, DHCP
eth1 - 192.168.0.0 internal "net1"
eth2 -10.0.0.0 internal "net2"
I want to add a fourth NIC, eth3, which will be assigned its own Public IP/Internet address (thru DHCP; my ISP provides two). The purpose it to route all net1's internet-bound traffic through eth0, and all of net2's internet traffic to eth3. This allows me to use one router/firewall machine instead of two separate ones. I anticipate that without some specific routing instructions, the default route will be eth0 for all net1 and net2 internet traffic (eth3 will be ignored).
I thought of using just one NIC (eth0) but create an alias (eth0:0), but IPtables (and possible DHCP) can't differentiate between the two (besides, nics are inexpensive). Is there a way to do this through routing commands, or even use iptables prerouting/forward functions (or is using iptables problematic)?

I was just wondering what the best approach is to allow mobile device sites on my web server is?Its an apache 2 server running on Centos and I am just very curious as to how to best present a site just in standard output for a mobile site, ie no server side programming or scripts (but would like to do some eventually).I actually have someone asking for someone on his development team and would love to be that person with that attribute lol.

From my main Postfix SMTP heads, I am sending just a couple select emails (primarily support emails) off to a server that receives them and pipes them into the support software. So far this totally works perfectly and I am pretty happy with the configuration. However, in order for sendmail on the support server to receive those emails I have to place them in the virtusertable of course, but I also have to activate their domain in the local-host-names file. That then causes sendmail to consider itself as the destination server for that whole domain.Is there a way to make sendmail receive email for select addresses without making it think it's the server for the whole domain? This server is only receiving email from two specific smtp servers, so I wonder if I could just permit relaying? Wonder if that would just cause a giant loop though.

How do clients handle offline syslog servers?Will the log files be buffered locally to be sent to the syslog server when it comes back online, or will any log data generated during downtime be lost in cyber space?

My intention is to have EngineX on the frontend handling all static files, and Apache + mod_php in charge of handling PHP requests. I have optimized nginx to be as efficient as possible in handling static files, but have very little experience with Apache. Since Apache would only be processing PHP requests, would the standard Apache optimization guides suffice or would it best to configure it differently?
PS: this is a dedicated file server, the database is hosted separately.

I have seen there are some tricks to handle transparents switches using Nagios. Does anybody know if it is possible to handle unmanaged switches connected in daisy chain?In my network I have some devices connected in this way [switch]--[dev_1]--[dev_2]--[dev_3]
where "switch" is a managed switch" and dev_i is a device with an unmanaged switch inside (no snmp available). All the devices have an IP address. Is it possible to get the network topology with Nagios?

I'm configuring Nagios at the moment, but I'm doubting my approach to transparent switches a bit. It seems from reading the documentation that Nagios wants me to ignore transparent switches, although I also doubt this interpretation of mine.
A little example, a VPN:
Code:
demarcation point
|
[router]
/
[switch][switch]
| / |
[7 clients] [switch] [switch]
/ |
[6 clients] [4 clients] [5 clients]
As you can see, there are 22 clients connected to the router. Since switches don't have an address, they cannot be measured. But if I ignore the switches, the schema is an oversimplified picture of reality. So what I'm looking for is a way to display the switches, even though they don't have an address. What I did was, I created the switches as where they proper fully featured ones, and listening to 127.0.0.1 as address. Luckily, this tricked Nagios. And it works, but it's not very elegant. Is there a better way to approach this pseudo-problem? Perhaps a build-in I overlooked?

My root server is using CentOS release 5.2 (Final), kernel 2.6.26.5-rootserver-20080917a, SMP, 64-bit This Oops happened yesterday and before that it happened on March 14th of this year, and before that on January 31st of this year, so a repeating pattern. On the January 31st Oops, I just rebooted. On the March 14th Oops, I reformatted the two swap partitions as follows: mkswap -c /dev/sda2; mkswap -c /dev/sdb2 On this last Oops, I turned off the swap for 24-hours, then decided to turn it on again after doing the above mkswap again. During the previous uptime, I had dumpcap packet capture running, but this last reboot, I'm not going to run it.

When I log in on an RedHat el5 machine (on the same network), every thing is ok, but when I log in on a fc14 machine my network homedir files are shown as "nobody nobody"
My homedir is placed on a REDHat el6 and using nfsv4
Does anyone have a clue as to where configuartion can be changed?

I have a registered domain (let say domain.com ) with a web server (www.domain.com) hosted somewhere online.
I handle the mail part in my private network, by giving the MX my WAN IP (111.222.333.444 )and NAT routing mail stuff to the mail server (10.7.167.3) It works fine.
I will have to handle sub-domains (foo.domain.com & bar.domain.com) and also another domain (anotherdomain.com) in my network. In that case NAT routing isn't going to work ...
What do I need to set this up ? I guess I need a DNS server in my network but I'm not sure if there won't be a conflict somewhere with the Registrar's DNS and mine. Or do I have to take the whole DNS of my domain on this new server and make it half public/half private in some way ?

The IP's are all in the same subnet, and use the same default gateway.Using ip tables and rules, will I be able to make all three of these able to handle traffic?I have the following configured, but it doesn't appear to work:
# ip rule
0:from all lookup local
500:from 72.43.220.146/29 lookup 1

I wrote a script which analysis apache logs. This script generates a tab separated data file. There is two columns in the data. The first column is a file name accessed from remote. The second column shows how many times a file access.
I am looking for a linux command drawing a chart corresponding data.of course, I know that I can draw the chart in OpenOffice Calc. That's not what I need. Because there is some steps to do for a simple chart drawing. If there is a command line tool, then I can write a script that drawing a chart when the data file is updated.

I have a file which looks something like this:
##########
some
text
text also includes empty lines
##########
some
more
text
##########
Basically all sections are separated by 10 hashes and I need to somehow only print all lines in the last section (the "some more text" part in the example above"). I tried all kind of things with sed and awk but I didn't find any way to identify the last "section".

I have some data ( seperated by semicolon ) with close to 240 rows in a text file temp1. temp2.txt stores 204 rows of data ( seperated by semicolon ). I want to : Sort the data in both files by field1.i.e first data field in every row. compare the data in both files and print out the rows that are not equal in seperate files. I was trying to do this with excel using vlookup, without a great deal of success. hence, i'm exploring the shell script option.
Code:
temp1.txt
