I have configured a CENTOS 5.5 server with DHCP + DNS. The network environment contains clients to obtain IP dynamically and some amy be configured manually. Until noe I have not used any GUIs for the configuration.
Now I want to manually add some hosts to my DNS. Can this be done by directly adding the host names to data files (pointed by the f/w and rev zones)? Or should this be done differently?
What are the good DNS GUI tools available for CentOS?
I've been trying to add a redirect iptable record but each time I add it, it appears to add successfully (meaning it doesn't throw me any errors); yet when I run 'iptables -L' I can't see it listed:
Trying to add my wife as a user to my computer, only to log on through SSH, not locally. Only problem is I use keys for logging in.
I've gone through the guide on the ubuntu website, created a key, copied to through a pen drive, put it in her .ssh folder on my computer, but it still comes up with the error:
Code: Agent admitted failure to sign using the key. Permission denied (publickey).
Is there a group I need to add her to, or add her public key to a different file somewhere?
I have a Fedora 12 and OpenSuse DVD with me. It consists of lots of packages and hence to install these packages I don't have to download them. What I want to do is copy the package folder on my local machine and then add them as repository in Synaptic Packet Manager.
I've noticed that the root account $PATH does not include /usr/local/bin or /usr/local/sbin by default. Are there any potential issues that could arise from adding those directories to the path? If so, what is the best way to make sure your shell finds executables in those directories, without affecting the stability and security of the system?
On Ubuntu, the local user is automatically added the xhost list when logging in (via a script in /etc/X11/Xsession.d).
Is there a way to enable this in OpenSUSE?
(My original problem is that I cannot interact with a running X session when loggin in via SSH, since newer GDM versions don't create $HOME/.Xauthority any longer.)
My test messages from one mail server to another are getting sent to my spambucket and the only error in the logs is: warning: numeric domain name in resource data of MX record for [URL]: 74.63.64.42

I'm currently tunnelling to my Ubuntu pc at home from my laptop in order to bypass my schools false-positive prone filter. Is there a way to record traffic that both comes to and is delivered by my pc?
I'm new to using a BIND DNS server. I currently have one set as a master zone on my LAN. My question is how can I add a record for my local lan that will resolve without typing in the FQDN? For example I want to be able to type "server" instead of "server.domain.com".
I am using bind for DNS services on RHEL 5. The forward lookup is working fine. When I try to do a reverse lookup at the server, it shows the correct output but when I try lookup from Internet it shows something like - "mysite.com points to a.b.c.d, which has no d.c.b.a.in-addr.arpa PTR record"
Here are the files: /etc/named.conf options { directory "/var/named"; statistics-file "/var/named/data/named_stats.txt"; };
controls{ inet 127.0.0.1 allow {localhost;} keys {rndckey;}; }; // Declaring reverse lookup zone // Declaration of domain name resolution view intranet { zone "mysite.com" { type master; file "/var/named/mysite.com.intranet.hosts"; }; .....
Im working with virtuals machines to configure Sendmail on Linux.
I work with two domains (ar and org), the configuration is similar in both, so i will write just one.

I'm running Ubuntu Server 10.04 to provide DHCP and Internet Sharing on my home LAN. In a previous configuration, I was running Fedora + AMAHI to provide the same services. As most of my linux devices are Ubuntu, I decided to decommission and rebuild my server. I've been able to configure all of my services with the exception of one. As a rule, I assign static IP or reservations based on MAC address's for any of my network devices or appliances.
One cool feature that AMAHI provided a GUI for, was the ability to recognize devices by name as well as IP. i.e.. "http://192.168.1.50" or "http://home-NAS" Going from memory, the long name upon first entry may actually have been "http://home-NAS.adomainname.com"? From my reading, I think I either need to setup up a Static Alias or CNAME for each assigned IP. I can't find any tutorial's that will walk me through this process. I'm guessing I need to generate the records under one of the master DNS zones, but that is just a guess?
I have an idea to install a video-camera to record 24/7 the place in the yard where the car will be kept. Can not say that I'll configure such a system for sure, but I have an interest to it. On the other hand I've never worked with such systems and I don't know what cameras are better, should they be IP-based or the USB-webcam will be OK, I also do not know much about the software. I've found that gphoto is a good software for such a purppose, and some photo-cameras can be managed remotely through console, I mean that we can take pictures/?video?
Remotely, if the camera is connected to the Linix-box via USB. Another soft, which I googled, which (as I understood) is de-facto and which is powerful, is ZoneMinder. Today a friend of mine told me that many IP-cameras have everything inside them (a webserver, many tools for capturing video/photo and so on), so I just need to create some directory on the PC, where it will store all photos/videos. So, as you see, I know practically nothing about all this. That's why I decided to listen to you, what software and photo/video cameras would you recommend me.

I rented a server to run CS 1.6 game servers. I had someone install Apache and configure my server to be able to use control panel for my game servers( i am running 4 gservers and have 5 ips = 1 ip is free). When i type my primary ip in the web browser it displays the Apache test page.
My question is can i add pages to the Apache without messing up anything with the control panel or my game servers. I am familiar with html. My primary ip is used for 1 of th egame servers but i can change that if necessary. And if possible to add pages how to add a site name, sth like [url] instead of entering the primary ip to display the content.
I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code: sudo tcpdump -i vlan4 -n tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
I am having problem to collecting email from remote POP3 (all the emails for a domain is stored here) and distribute it after collecting to several users defined to Linux server. I have install postfix in Linux server for email distribution.
I've tried /etc/init.d/mysql start, and it actually starts, or at least, it doesn't error out. But when I do pgrep mysql I get nothing, and when I try to login with mysql -p as root, I get
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
None of my other logins work, either, but since pgrep mysql didn't work, it's clear that MySQL just isn't running. I tried uninstalling and reinstalling mysql-server via apt-get, but I get the same thing. The logs in /var/log/syslog show this:
Apr 11 14:31:26 /etc/init.d/mysql[9774]: #007/usr/bin/mysqladmin: connect to server at 'localhost' failed Apr 11 14:31:26 /etc/init.d/mysql[9774]: error: 'Can't connect to local MySQL server
