I have installed the nagios by FAN 2.0 CD. In this distro all the required softwares are bundled. Now i do not know where to start. How can i monitor my other server on the network. I have google on the internet but it is not giving the clear idea. Is there any document on the net or how to which can show that how to configure nagios with centreon or originally from changing nagios files.

Now I want to monitor some servers which are located remote location(network) and they haven't real IP(all are behind route/firewall). I can allocate real IP to nagios server if require. How can I monitor those servers?

View 1 Replies View RelatedWe 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:

We have Nagios running on a server, and are installing NRPE as a daemon on web servers we need to monitor. I'm two servers in and have hit a small snag. The two servers we're currently trying to monitor are, to the best of our knowledge, very similar (Centos 5.4, Apache, MySQL, PHP etc etc), and the installations of NRPE on them should be the same. One is being monitored just fine, however we can't check on the other one without including the -n switch (to disable SSL) in the check_nrpe call. If we don't, however, the error we get is, "CHECK_NRPE: Socket timeout after 10 seconds.". In /var/log/messages on the machine that fails we see:
May 24 17:23:49 ourserver xinetd[23583]: START: nrpe pid=27932 from=123.123.123.123
May 24 17:23:59 ourserver nrpe[27932]: Could not read request from client, bailing out...
May 24 17:23:59 ourserver xinetd[23583]: EXIT: nrpe status=0 pid=27932 duration=10(sec)
The only kind of related thing I can think of that's different between the two machines is that one (the one that works) has actually had an SSL certificate installed on it, for the site it hosts.

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.
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.
I have just installed CentOS 5. I have set mysql database to access from remote machines. But now the problem is it is not connecting from the local machine now.
View 5 Replies View RelatedWe 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.

View 6 Replies View RelatedIs there any way to setup the Centos Directory Server without an internet connection?? i tried using the command: yum install centos-ds
but this just tries to connect to the internet to to download the packages. Is there a site where i can find the package so that i can copy it to my server and install it or is there some other way to do this?
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).
View 2 Replies View RelatedHave 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"?

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

I am trying to accomplish an objective, I need to get 389 Directory server installed in the process however is it possible to just have email addresses of users in the LDAP server? I have a primary domain, example 'abcefg.com' with about 3,000 users and several hosted domains like 'xyz.com' and 'mno.com'. The end goal is to speed up email processing, so instead of the Barracuda asking the email server(s) if a user exist it queries the LDAP.
Is there a way to configure 389 Directory Server to contain just the email addresses of the end users to allow the Barracuda to poll the LDAP server to verify the email address is valid. The rest of the authentication like password is handled by the email server. So in the end the LDAP server would just contain the email addresses (live) and the Barracuda would query the LDAP asking if joebob@abcefg.com exist if it does carry on. If user xxeedd@abcefg.com does not exist drop it and go on.
Still new to Linux and especially samba. I have setup samba for 2 shares, will list below shares. 1 which requires a login and 1 temp folder which I would like guest access to. Currently I have security = user which works great for the data folder which requires a login. If I try to access temp I get asked for a user name and password as well. I tried to set security = share which then allowed access to temp with out a login but also allowed access to the data folder. From the data folder I emoved public = yes. I then get asked for a user name and password like I should but the system will not accept it. This is a Centos 5.5 server with a mail server on it.
