I would like to have a web site pop-up on the persons laptop that connects to my wifi network. The page will let them know this is my network and give a list of shares on the network. Then click ok to get wireless authentication. Something like you get when you connect to a wireless connection in a hotel. software i can install on my Ubuntu 9.10 server to do this.
View 1 RepliesThe first is regarding my home network that I've setup. It mainly consists of two laptops, both running fedora. I find myself using rsync, ssh, scp, and the like quite often, but it is very annoying constantly needing to provide a password. This sounds like a job for RSA keys, but is it safe to do so on my laptop I take whenever I travel? If my laptop were to be stolen, my personal and private keys would be available to the thief. Is it instead better to use something like kerberos (which I'm not very familiar with, ie. I've used it at work but never took the time to learn how it works).
This isn't much of an issue with my home network since it is protected behind my router. However, I have the same issue with rsync, and ssh to my work PC. These are the RSA keys I'm worried about if my laptop were to be stolen.
I'm looking for an solution to get an automatic authentication and login to my FON hotspot. I did some search on this but I can't find an solution on this. Is there a way to get it work? I'm running on Ubuntu 10.04.

how do i get it back to the original setting so that it asks for a password before allowing me into the editing screen? i tried preferences > system > authorisations > network-manager-settings, but it didnt work.
I have set up a small Mesh Wireless Hotspot at a local Flea Market.

I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.

I am attempting to connect to an unsecured wireless network; I helped set it up for my local club with a local ISP. Once things were up and running I took my wife's laptop running Ubuntu 8.04.3 and Wicd. Can see the unsecured network no problem, good signal, hit connect, whirs away for awhile, then: 'Unable to obtain IP address.' Strange. I am about to give up and report back to the ISP when I think I might try one of the old Windows boxes in the computer room. Spots the network, hit connect, online, no problem.
So Windows connects fine, Ubuntu box can't get an IP though no doubt the router is trying to serve it one.
setting up a netbook's wireless access point (to allow remote connection to a network drive connected to the netbook). I know this sounds daft but there is a reason.I just switched workplace and have all my projects on one drive.However my new workplace's network only assigns ip to certain Mac addresses. So I can't just plug in the network drive.My new work desktop is MS loaded, warranty sticker sealed and shared so I can't change this.Well I will, but not in the first week.
The simplest solution I thought of was to bring in my ubuntu netbook connect this to the network drive and wirelessly connect the netbook to the new desktop this via a wireless USB dongle.I connected the netbook to the network drive with no problem using the wired card. I done this by adding
Code:
auto eth0
iface eth0 inet static
address 192.168.4.1
network 192.168.4.0
[code]....
For the wireless bit, on the netbook, I right clicked on the network indicator icon and selected "Create New Wireless network" then entered a network name and WEP passphase.Over to the desktop (XP). I plugged in a wireless dongle, get it load the driver then selected my new network and entered the passphrase. It came up connected and sure enough I check and it got assigned a sensible IP.
All seemed well and I even connected my android phone with no issues. The phone and desktop can ping each other. However for some reason I can't actually ping or ssh to or from the netbook.So whilst it's happily providing the wireless network it can't use it itself.
p.s. Incidentally I am allowed to plug in USB drives so this isn't an access issue or me trying to sneakily circumvent rules. I even told my IT department about the wireless dongle plan.
I connected a USB Wireless Dongle (Sapido AU-4512S) on my Ubuntu 10.04 64bit. I wanted to share my wired internet connection from my pc to my friend's laptop.
So, I did the following:
1. Installed ndiswrapper-utils, ndiswrapper-common and ndisgtk in Synaptic Package Manager.
2. Installed Windows 7 64bit driver of my USB Dongle through Wireless Network Drivers(ndisgtk)
3. Now it says, net8192su -- Hardware present: Yes
4. Created a Ad-hoc connection clicking on Network Manager > create new wireless network..
5. Edited the Name, set Security to WEP 128-bit Passphrase and entered my desired password.
6. Finally clicked Create but it says "Wireless Connection disconnected"
I'm thinking about maybe the problem is with my dongle so I checked by using the command:
Code:
which gives me information about wlan0
The next thing I did worsen the situation. I unplugged the USB dongle ang plugged it again. This time,
Code:
gives me no result anymore.

Also, the option that says "create new wireless connection" disappeared in my Network Manager Applet now.
Now I have no problem. To restore the "Create new wireless connection" in my Network Manager Applet and finally create a wifi hotspot using my wired connection from pc.

i wish to install hotspot shield so help me to install hotspot shield & send me the link of software hotspot shield.
View 3 Replies View RelatedMy school has (once again) chosen to change their wireless network. This means it has gotten a lot slower, and that only our hotspot works. Our hotspot however is secured so that im unable to enter facebook, and a lot of other websites, etc. So what i did in windows was installing a program called hotspot shield, which redirects you ip through a server, so the LAN Admin basically have no control of what you're doing if he haven't got more skill than the one we have. I think what Hotspot shield does is making a vpn connection (correct me if im wrong) and i would certainly like to do that i ubuntu as well.

View 3 Replies View RelatedI am trying to build a ftp server with vsftpd. In general, I am not able to log in. I can only log in to the ftp server, if that same user is logged in to the server. I found out that this has to with my network setup. I am using OpenLDAP for centralized authentication and home directories are stored on an NFS server. The problem is that regular users are not allowed to log in to servers, therefore their home directories are not mounted. However I want to be able to give my users access to the ftp server without their home directories mounted. Is this possible with vsftpd and if so how do get this up and running. By the way, anonymous users are not allowed.

I'm working on a work project related to Web (Client) authentication and DOD Common Access Cards. But I'm having difficult getting the details about what happens on the CAC side of things.
I familiar with the PKI system as it applies to e-mail. (Correct me if I err, of course.) If you want to sign an e-mail (i.e., so it can be authenticated by the receiver) you use your private key to add a digital signature to the message. Then, the receiver uses your published public key to determine if the digital signature is valid, i.e., was created using your private key (even though the receiver never actually has access to your private key).
So... my questions:
1) When a person with a DOD CAC visits a CAC-enabled web site, and the server grants access after the CAC is inserted, is the authentication process fundamentally the same as what happened with the e-mail authentication?
2) If the private key is used in this process (it would have to be, correct?) is the signature created on the CA Card electronics (i.e., the private key remains on the CAC)? Or is the private key copied onto the computer, which uses it to create the signature?
My server is connected to the Internet for ssh on port 22 with root logon disabled, a single non-dictionary word user name allowed, and pki authentication only (about as secure as I can make it). I've previously run fc5 and 9 servers using the same sshd config since 2006 and had no security troubles, so I'm happy, but.. After the fc13 install and configuration, logins from a host on a remote network are taking about 1m 30s to complete! A (partial) console output for ssh -vv appears below. The lines marked with "**" were the lines after which significant pauses happen. This is fully repeatable.
Code:
debug1: Next authentication method: publickey
debug1: Offering public key:
debug2: we sent a publickey packet, wait for reply

having a slow internet connection, I bought the all maverick repository on DVDs, copied the files on a usb drive and modified the apt sources file to consider the local repository only:
Code:

deb file:/var/www/maverick/dvd2/ maverick main universe restricted multiverse

Even though I am reasonably sure it is safe, this local repository is not authenticated and I can only install package through the command line or synaptic, the Ubuntu Software Centre giving an error message "Requires installation of untrusted packages"...I thus would like to disable the apt authentication check for this local repository.
Does anyone know if/how its possible to integrate HOTP authentication into GDM login manager? Basically what I want to do is have it ask for the password of the account, then another prompt come up asking for the code for the account.
