CentOS 5 Server :: Setup Distribute 5.6 Over A The Network With PXE?

May 19, 2011

I'm trying to setup a server to distribute CentOS 5.6 over a the network with PXE. I found and followed [URL] but that guide is certainly incomplete. I have DHCP working and other machines will try and boot but get a TFTP timeout. I don't plan on using Kickstart at this time. What do I need to do next? What am I missing?

CentOS 5 Server :: DHCPD On ETH1: Distribute ETH0-received DNS?

Sep 14, 2009

this should be trivial for all you big sysadmin guys My box is a firewall/gateway. ETH0 is on the Internet-side, and is fully auto-configured (DHCP client) from my ISP. ETH1 is on the LAN-side, has DHCPD enabled, and I route the traffic to/from the Internet via iptables (NATting, of course). Everything works pretty good, except for the DNS-server assignment via DHCP: how can I configure dhcpd.conf to assign the SAME dns-server I receive from my provider on ETH0 to all my PC on ETH1?

Server :: Distribute Securenets File From NIS Master To Slave?

Jan 25, 2011

I have a large environment with many VLANs and NIS slaves serving the VLANs. Previously we have not used a securenets file (don't worry; we don't use NIS for passwords, just NFS maps), but I'd like to start. The number of NIS slaves makes it annoying to update a securenets file on each when we add a new VLAN. Is there a way to propagate the securenets file to each slave when I update it on the master?If not, I guess I can live with propagating the file once and only visiting new slaves when I build them, because in 99% of cases a NIS slave only serves its own subnet.

Server :: Unable To Setup A NIS Server Setup On CentOS System

Jan 19, 2010

We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.

Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".

I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .

Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?

Is there any other files which need to be changed? Are we missing any steps?

Also to add-on, while executing the ypinit command we faced the following error:

At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:

The current list of NIS servers looks like this:

Is this correct? [y/n: y] y

Error running Makefile.

OpenSUSE Network :: Setup As A Network Boot Server To Install Solaris 10 On A Sun Ultra 10 Client?

May 12, 2011

I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?

Software :: Get An X Window Server Setup On My CentOS 5.3 Server Rack?

Jan 5, 2010

I am trying to get an X window server setup on my CentOS 5.3 server rack. I have gotten as far as to doing:

yum groupinstall "X Window Sever" "GNOME Desktop Environment"

EDIT-Forgot to mention that I did Xorg -configure before testing the config. Only errors I got were:

(EE) LoadModule: Module ati_r500 does not have a ati_r500ModuleData data object.
(EE) Failed to load module "ati_r500" (invalid module, 0)

[Code]...

Linuxquestions--I posted this over on the CentOS forums, which are not as booming. Then I remembered these forums for when I had my VPS way back when and you guys were pretty helpful, of course expected me to mostly do my own reading which I dont mind its just having a hard time understanding some of the things in what I was reading. I even believe I came here with this problem before but abandoned the issue because my VPS was not powerful enough or something of the sort, but this was many years ago also on CentOS using apt. Now using yum which I like much better.

CentOS 5 Server :: Email Server Setup Using Sendmail And Dovecot?

Apr 24, 2009

I am trying to set up a mail server on centos5 using sendmail and dovecot, and eventually spamassassin and some antivirus filter as well. I'd also like to get the proper secure auth mechanism set up at some point too. But for starters, I've been having a lot of difficulty trying to even connect to the mail server from a client computer in the local network. I installed Eudora on the client and after some tweaking in dovecot I was able to connect to the mail server, but then when I try to send an email I get a "connection refused" error, with nothing being logged on the server that I can see.

The last time I set up a mail server was Fedora Core 2, so the configuration files have changed a bit to say the least, and I can't really refer back to those to set up this new server. Does anybody know of a good step-by-step doc on getting the mail server going? I've read the man pages and other various readme's, but these really only list out the available options with no really good explanation of what needs to be done to get the mail server going. If there isn't a full write-up on how to do this, I'll put something together when I'm finished so others can use it in the future.

CentOS 5 :: Easiest Way To Mirror Existing Server Setup On A New Server?

Jan 13, 2011

We have two CentOS 5 servers in production (web and database). We are setting up a single staging server that will mirror the configurations of these servers as closely as possible. What is the easiest way to ensure the exact same software and configs as the production servers are setup on the new staging server. Our contracted data center provider has already informed us that they do not perform images and NO we do not have physical access to the machines. It is undetermined whether we will be virtualizing the staging server into two virtual servers yet, so for the purposes of this post lets assume we are not. I'm seeking a faster/more precise method than doing this by eye and hand.

Some information on our web server code...

I just recently purchased a vs from a company and i am trying to set up a web site on it with kloxo and set up the mail for it upon setting up the mail settings it says:

"It is very essential that you set the my name to a properly resolvable hostname, since otherwise, many public mailservers like hotmail will reject mails from your server"

Now this is my first time setting up a vs before i have set up linux vm's to get email access but that was about a year ago.

CentOS 5 Server :: How To Setup A Backup

Jun 27, 2011

on my server I have atMail and a intranet site being hosted using mySQL for the database locally, and obviously backing it up would be a good thing. I got the backup package from the list if you use the add/remove software called dump-0.4.etc.. can't seem to find much on how to use it, set it up, nothing. Granted I could be looking for the wrong thing which I'm sure is the case. As of now it's looking like a USB drive is going to be my only option, that will change in the future as this "project" goes further (we are a windows shop trying out Linux, and the next step is going to be adding another server that's a file server at that point we'll probably go to NAS for the backup and then transer that to a USB for offsite/secondary backup).

Server :: Setup A CentOS 5.5 With IPSConfig?

Nov 2, 2010

Have setup a CentOS 5.5 with IPSConfig that has been running for maybe 6 months, it was only intended to be a web server for multiple domains. Issue now is that a web developer has created a form that he is trying to email from the site, I did not have anything configured for mail and he does not care to write a script that would not require the mail service to be on the web server.

Have configured/reconfigured main.cf multiple times but no success.

Postfix appears to send the outbound email to the queue but never goes out. Have setup mail service for the domain "land***.com" in ISPConfig and tested with a single user created for the domain from the server.

What did I miss in the configuration to get "connection refused"?

Nov 2 11:27:19 WC01 postfix/cleanup[6711]: E4DFA1190011: message-id=<20101102162712.E4DFA1190011@WC01.nors***.com>
Nov 2 11:27:19 WC01 postfix/qmgr[6665]: E4DFA1190011: from=<admin@land***.com>, size=377, nrcpt=1 (queue active)

[Code].....

should I remove the domain from mail services and would postfix work on its own on a server with ISPConfig?

Server :: Setup An OpenVPN Using CentOS 5?

Dec 7, 2010

I am trying to setup an OpenVPN server using CentOS 5. I ahve installed everything, configs are good, server starts fine. I have generated my certificates using the easy-rsa 2.0 included with OpenVPN. I have downloaded all the certificates to my machine and setup my client to connect. I am having that typical problem everyone seems to have where my client says certificate verify failed. However I can use openssl on the server to verify and it is ok. What am I doing wrong here?

Code:
[root@GSFOVPNxxx01 openvpn]# openssl verify -CAfile ca.crt gg-jbloomer.crt
gg-jbloomer.crt: OK
[root@GSFOVPNxxx01 openvpn]#
client output
Code:
2010-12-07 08:44:33 MANAGEMENT: CMD 'hold release'

[Code]...

I just dont get it, I have racked my brain and google until my eyes bleed and can not figure this one out.I am sure it is something simple that I am missing.
