Ubuntu :: How To Setup DMZ Connection
Feb 22, 2011
In our company we (I) have recently setup a Ubuntu Machine on an old Dimension 8300 to act as a download machine. The reason for this is alot of Tax websites Push word and excel documents through their website as the viewer needs it and we have our WatchGuard setup to block all downloads. So i created this Linux Box to be hooked up to the DMZ in order to have the ability to download these files among other things then scan them for viruses, then put them on a flash drive to let the person have it.
First i Setup VNC so i can remotely maintain this server without leaving my desk because i am Lazy, however it is still on our network so i am able to remote in.Step Two was to set it up on the DMZ. So i thought easy enough just setup an IP, and preferred DNS for it and ill be done. how i would go about Setting up a DMZ connection

I am running an Ubuntu Server on a VirtualBox VM running on my windows machine. So I've created a self-signed certificate using the following tutorial: [URL]
From this tutorial I'm left with 3 files:
server.key
server.csr
server.crt
Then I found this very similar tutorial that has an extra bit on installing the certificates in apache: [URL] So I followed it's instructions which boil down to this:
[Code]...
So I'm thinking this should work now. However in Chrome I get: SSL connection error Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. IE8 gives me a typical "Internet Explorer cannot display the webpage" Note that [URL] fails while [URL] works fine, so it's definitely something in my ssl setup I'm thinking.

I am trying to setup multipath with failover policy on openSuSE 11. I have two qla2xxx HBA's installed and they appear to be working. Here is the output of "multipath -l" command
[Code]....
While testing, I pulled one of the two connection to SAN, and the connection failed over to second HBA connection to SAN. When I plug the cable back in, it does not fall back to original connection... It stays in failed state. Also, I noticed that failed disk (sdd disk) comes back as (sdg disk), which is probably why connection does not fall back to original HBA. But, when I run "/sbin/service multipathd restart" sdg disk shows as as enabled in multipath -l...

I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code:
pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error
pppd[4104]: Cannot determine ethernet address for proxy ARP
in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?

I use 10.04. I have network-manager, openvpn, pptp installed open vpn requires some certification files that I don't know where to get from and the guys who are providing the vpn for me don't offer any, actually they don't know anything about Linux and Ubuntu. I can easily make a connection for windows xp but in Ubuntu...
For pptp:
I enter my gateway as the "host in win XP": vpn.their-website.com
my user name: *****
my pass: *****
I leave the NT Domain field empty since I have no idea what it is? Apply, and the connection will be created. But, now, how the hell am supposed to connect? I looked all over the net but nothing! And please don't refer to something in panel (the network notification icon) I have deleted all the panels and in main panel I've removed every icon, tell me what to do in menus or in terminal.

I followed the tutorial found here [URL] but when I try to access [URL] I get the following:
Code:
Secure Connection Failed
An error occurred during a connection to www.mydomain.com.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
Not sure what I might have done wrong... I have retraced all of my steps and I don't believe I missed anything.

My adsl modem is in bridge mode. I can connect to internet via pppoe . pppoeconf recognise the pppoe in eth0 and setup a connection and I can use it. How can I setup a pppoe connection using pppoeconf so that it uses wireless ? I set the wireless mode to bridge in modem settings. But, after that the access point stopped appearing in "aps in range" in network manager and I can't connect to it. pppoeconf also doesn't recognise wlan0 as a valid pppoe link . but dat is normal since i don't think it can check if wlan0 is pppoe without wlan0 being connected to the modem's wireless network. How can I connect to Internet with modem in bridge mode and connections via wireless interface of modem? Is pppoe over wireless even possible ? coz the datalink layer of wlan is not ethernet rite?

I have BIG troubles trying to set up wired internet connection in Ubuntu! To be able to connect to the internet I have to enter my MAC address, 2 IPs, netmask and 2 DNS address. When I try to edit the default internet connection eth0 with my correct information, the minute I enter my MAC address and save the changes the network manager creates new internet connection with wrong data and use it instead! I can't select the correct internet connection from the top bar where the internet icon is, because it is just not there. The only connection that I can choice is the new default one with the wrong data! If I try to create new separate internet connection with my correct data the same thing happens! The moment I enter my MAC address and save it, the internet connection disapears from the list of internet connections in the internet area in the top bar and I can't select it. I tried googling it, but with no luck I think that if I set up my connection trough the terminal everything will be ok

I would like to set up a remote desktop connection between two computers over the Internet. I already tested remote desktop within a local network but it's far from secure enough this time. I will try to follow this guide [URL] (ssh portforward and internet). This still leaves ufw and how it should be configured. Let's say I have this setup, server computer has ip 12.341.245.124 and the client has 78.12.543.234 how should ufw be configured to be secure? This remote desktop wont be connected to a local network

I have a computer with both wire and wireless connections. Wired connection works fine, but I would also setup the wireless connection.(I also have a dual boot on this cumputer with WinXP where both wire and wireless connections works fine. So, wire and wireless configuration of the actual router is not an issue here.)
At this point I just want to know the main/overview basic steps of setting-up the wireless connection on the computer. Also if you could suggest any links to guidelines for these steps. I have been thinking about something simple like this, but I might have missed a lotInvestigate if Ubuntu finds the wifi-hardware - the installed wifi card.Investigate if Ubuntu have an installed driver for this wifi-card.Configure the Wireless Network connection, like SSID.Unplug wire connection and reboot.

I have a similar problem. My ubuntu box is set up as a dhcp router for my Xbox360, my xbox can get ip and DNS information from the computer, but it doesn't seem to get the right info. The ip address it gets assigned is out of the range I've set in etc/dhcp3/dhcpd.conf.
