I have a bunch of Windows servers and they all connect to 2 networks. One of them is all public IPs (an entire /24) which is protected by a pfsense firewall. The other network is just a 48 port gigabit switch that each machine accesses using a private (192.16 static IP on a separate nic. There is no gateway/DNS/DHCP server on this private network and we want to keep it that way.
I want to deploy a ubuntu server that will connect to both networks. This server will not sit behind our firewall. It will have a public IP address from our /24 and be connected to the switch that feeds our firewall and a second nic with a static private IP that will be connected to our private network. This server will need to run nagios, run a few command line items that grep log files and serve the output via apache, and act as a VPN to allow an outside machine secure access to the private network. Sitting on this private network are various web based GUIs for the switches, UPS boxes, etc that we do not want exposed directly to the Internet. Both of these networks are mission critical so I can't change any existing settings and I can't add anything to the existing firewall. There would only be a couple of VPN connections at a time.
Do you think that ubuntu 10.04 LTS server (32 bit) would be able to handle this? I am looking at running it on a supermicro Atom D525 box with 3G of ram and a small SSD for storage.
I have been running a webserver for a time now. And for fun I thought I would use Nagios for monitoring it. But the installation instruction says install this on webserver01 and that on webserver02. I only have one server and want to monitor it remotely from a simple browser. Is this possible or does Nagios need at least two separate servers? Can't it just run it on my one server?
View 1 Replies View RelatedI started my install of Nagios on Ubuntu 9.10 w.Network Manager. I later found out that network manager doesn or should I say it makes configuring static ip's difficult and that the most direct approach would be to edit the interfaces file. Part of this I read that network manager could be removed, which I did however now with network manager deleted from the system and the interfaces file configured for static. I am able to view the internet however I've seem to have loss the ablity to see my Nagios page locally.
View 2 Replies View RelatedI need to set Nagios and permissions. I get one critical error in Nagios regarding disk. It says:
DISK CRITICAL - /home/administrator/.gvfs is not accessible: Permission denied
I guess Nagios need a permission to access the administrator folder. How can I set up a permission to fix this error?
I'm trying to setup nagios, and I've looked at several guides but none of them seem to address my problem.Here's the clearest guide that I followed URl...I followed all the instructions on that basica guide, except disabling SELinux. I changed SELinux rules based on URL...I'm not getting any AVC Denials, so that's not the problem. Nagios and Apache both start fine. If I go to my local IP, I get the standard Apache test page. URl...(address from all the guides I read) doesn't resolve.I know that Nagios is at least running from "service nagios status," and I have gotten two alerts emailed to me: swap alert (I don't have swap configured) and disk space.

View 1 Replies View RelatedI have set up nagios on Suse 11.2 and it is working fine on the localhost. I can access localhost/nagios, <ipaddress>/nagios in the browser and it loads up the nagios webinterface. If I try on a computer on the network with <ipaddress>/nagios the request times out. I have tested that I can ping to and from both machines (nagios machine and the machine I am trying to access the interface from).Some detailsNagios is running in a hyper-v VM. I installed it through yast2. Communication is run via a switch and sonicwall firewall but firewall has allow all within the network.I have a feeling it's some apache2 setting that I haven't configured or something blocking port 80.

View 1 Replies View RelatedI installed Nagios on my Ubuntu 10.04 server using apt-get and when I accessed the web console, everything was OK. I made some changes to apache (creating some new virtual sites) and since then Nagios gives me a warning message for HTTP with the message, HTTP WARNING: HTTP/1.1 404 Not Found. The sites that I created are working perfectly. I noticed that the attemps are 4/4. Does this need to be reset or does Nagios automatically reset that once it detects the issue is resolved?

View 6 Replies View RelatedI've installed Ubuntu Server 10.10 with two network cards. One for external, and one internal.My problem is that as soon as i activate eth1 (external), i can't access the server from the internal network (eth0)
With these settings i can't reach the internal network from inside.If i disable the gateway on eth1 and enable the gateway on eth0, it works.
Problem with my Internet connection. I can't connect to the update servers. I don't know why. It's a brand new installation, not a week old yet. I can't install the support for restricted media for example. The servers won't refresh in YaST. It tells me it can't download the repomd.xml.asc.
The other problem is that some servers on the web won't load for me either.
For example, I get most of my local news from The Toronto Star, and I can't connect to it's website at all.
I can from Windows (I dual boot) but not SUSE. I don't think its a problem limited to that one website either. I am able to connect to most websites though.

The Question: Why won't my damned Ubuntu server just stay connected to the network?
I have this 7.10 Ubuntu server that I'm trying to move inside a VM on my ESXi server. I use the VMware Conversion tool and everythings goes well until I try to boot it from inside the VM, the network isn't detected. Now I understand that the drivers may not be working, I'm not an expert here. Also, since this is a 7.10 install I don't have access to the Gutsy repositories anymore.
View 3 Replies View RelatedI'm in a strange situation where i have a windows host with a Ubuntu Server VM running Proftpd which needs to be able to ftp files to a shared drive on the host. This is so the webserver (a separate VM) can access the files in the ftp directory. Also so i can take snapshots of the server without the ftpd files. So, my question is how can i do this? Am i able to mount the share somewhere and use that to store my ftp accounts/files? Is it possible (or is it a stupid idea) to mount the home directory on the share?
View 1 Replies View RelatedI've been having a hard time googling and trying to get ALL network connection to be redirected to squid proxy. I couldn't find a proper configuration for ufw or iptables. The ideas are:
1. redirection rule should NOT depend on a specific network inteface, but should work with any connection type, ex.: ppp0 or eth0... 2. firewall rules can be for firehol, iptables, or ufw (the same as iptables, just tell me where to place them). Preferably ufw or gufw. 3. should not interfere on cups web interface and lighttpd server.
BTW: it's not a ubuntu server install
I've followed several guides and am trying to get NFS working on my local network. For starters, I think I should be able to NFS mount a drive on the server (192.168.1.65) TO the server. From there I'll work with another client (currently 192.168.1.80)
Code:
$cat /etc/exports
/media 192.168.1.0/24(rw,no_subtree_check)
$cat /etc/hosts.deny
portmap mountd nfsd statd lockd rquotad : ALL

The guides I've read seem simple, so I must be missing something easy. Can't figure it out, so I'm looking for help after googling for 2 hours.

View 1 Replies View Relatedso i just downloaded Ubuntu Server 10.04 and i'm very happy with it on my virtual machine... but when i try to install it on my actual server it fails.
When i went to install it, it told me that there was no network hardware detected or something like that. So i just thought i could install a driver for it later.
So other than that all went well. and im very happy but now i dont know how to install my network driver. The card is a LYNKSYS LNE100TX. i downloaded the driver software and burnt it to disk because i was out of floppys. (I like floppys better) and when i went to install the software it allmost worked but it said:

make: gcc command not found
I'm assuming that means i need to install gcc but didn't really know how to go about it having no internet.

I have been able to ping the router. I cannot, however, reach other computers on the network. Nor can other computers ping the server.I am looking for a newbie guide on how to connect to my local network.
