Server :: Server Ip Address Configuration
Jan 2, 2010
i recently built a server running openSUSE. when trying to connect via ssh or telnet or ftp etc etc on my LAN, everything is ok. i just recently found out that when i try to connect to my world ip address {the ip address everyone else sees,] it does not work. i recently came to the conclusion that since the server i built is running off a router connected to another computer, my world ip is the same as that one, and there is no server built on that computer. is there a way i can connect to the computer that is running the server on my network from outside my network i.e from somewhere else?

I'm running gnome desktop on squeeze system. When I boot my system seems to be using my internet modem as its dhcp server. The rest of the machines on my lan are correctly using my router for that purpose. As a result, what happens then is that my debian machine frequently gets a duplicate ip address assigned to it. I would like to specify to my debian computer that I want it to use the specific fixed ip address of my router for dhcp purposes.

Hey guys. I have a client computer PXE booting from my host computer and it is supposed to give the client the ip address 172.16.0.100 however instead it gives it the ip address 172.16.0.208.
I have this set up working with two other computers and there is no noticeable difference other than mac addresses for the network card.
Here is an extract from my '/etc/dhcp3/dhcpd.conf' file...
ddns-update-style-none;
option domain-name "example.org";
default-lease-time 600;
max-lease-time 7200;
[Code]....
I have quadruple checked the mac address of the client and it is definitely "00:07:E9:32:16:81" so why is it not giving it the IP address that I have specified?

My father has configured his network and the computer has connected to the wired network. The problem is firefox says the server cant be found at the given address. The wired router says its connected to the network and yet firefox doesn't see the router admin page or network.

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.

Right now i have a HP DL 180 Server with 130 Gb Hard Disk & 8 Gb ram after Raiding0+1. i want to configure Domain Controller Server for my office for 200 to 300 Users. what should the partition size must be mentioned in my 130 Gb Hard Disk, is that going to be Sufficient for ME ?
i am bit confused about /Usr /Var /Boot partitions, as i need to manage perfectly in 130 GB
if i go with 4 Gb swap and remaining for " / " is that will be fine ? should i need to specify partition sizes separately for / tmp /var / usr ..

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I'm having a problem whereby I'm able to send mail to a mailbox from several different email addresses and SMTP servers (gmail, RoadRunner broadband), but I'm unable to send mail to the same address from one particular account, the SMTP server for which runs on a mediaTemple (dv) 3.0 box with CentOS 5 Final.I've spent a full workday on the forums, trying to troubleshoot the issue, and I'm running out of ideas.The server on which I'm having the mail processing problem is a mediaTemple (ve) running Ubuntu 10.04 x64 (Linux 2.6.18-028stab070.7 #1 SMP Fri Oct 1 13:53:00 MSD 2010 x86_64 GNU/Linux), with ISPConfig 3. Here's how I setup the mail-related aspects of the Ubuntu box:
Code:
apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d

One of our client having issue with the qmail. The issue is if any one send email to abc@ourdomain.com (abc@ourdomain.com the email address which is not exist) it should send failure notification i.e."email does not exist" to the sender. The qmail server is not notifying that email address does not exist.

I want to set up a dhcp server such that the clients get same ip every time. Giving fixed address to every client would be a long process.
"I don't want to assign a specific ip to the client but what i want is the server provides same ip every time"

I dont know for what reason, I started having this message whenever I try to start httpd.
I commented "Listen 443", restarted httpd started correctly.
I issued "lsof -iTCP:443", I get
Quote:
I can not understand where this come from and why. It seems that it is IPV6 protocol which is in fact not enabled on the network card.
Also, I can not find or dont know where 443 is configured apart from ssl.conf or httpd.conf
Today, I have added xrdp applications in order to be able to connect using RDP.

If you hadn't guessed it from my last 3000(ish) java-related posts, I'm a Java n00b writing a Java Applet for a work project. I got to the part was I was about to write the applet code that would send HTTP requests to my CGI scripts. But I read some paragraphs in a book praising Java servlets as better that CGI because they are easier to use and give much better performance server side. My server load isn't very big, though, and I was wondering if it would be worth taking the time to learn about Java servlets and how to set up the server side configuration on my Fedora web server.

I'm running the current release of Debian with the 2.6.26-2 kernel. This is an upgrade from an older (2.4 kernel) series redhat release. One of the things I had working in the older system was a dns server with accompanying monthly update of the root hints file. I tried working through a dns how-to to set this up again, but it seems much has moved around since I last played with this. All of the files listed in the how-to are not where it says they should be. I am looking for a better reference on keeping the dns server running with current server information.

LDAP is endlessly not working, due to difficulties to simply configure it. I even cannot make the first steps of the installations ... It seems so difficult ... After many howto, wiki, reading, re-reading the errors are still there, always different, and not working.Is there an admin, coming from hell, that made running a LDAP server for sharing the basic configuratin files /var.. /etc... of a working LDAP Server in a tar.gz?
