Ubuntu Networking :: Setting Up Wireless - Unvalidated Server Certificate
Oct 26, 2010
Security Type: WPA2-Enterprise
Encryption Type: AES
Network Authentication mode:
Microsoft: Protected EAP (PEAP) - Unvalidated Server Certificate
User must authenticate log-on. Its a wireless network. how to set this up for Ubuntu.
The collage I am going to has a secure wireless net work that we are suppose to be able to log into with a user name and password they give us. They have instructions on how to connect with windows and mac, but not for linux.There tech support has not been any help and I have tried quit a few different combinations but with no luck.
According to their instructions for windows their net work uses WPA-Enterprise for security type, and PEAP. They do not seem to use any root certification authorities, and they have you unchecked "validate server certificate".At [URL]there is some similar thing were you can see screen shots, but I cannot follow these because I do not know what "CA Certificate" to use. Is there a way to do it with out a "CA Certificate"?
I am trying to connect to wireless in my office from my ubuntu. I checked with IT - as per them our office is using Acess Point networking. On a Windows machine I need to go to some URI in Internet explorer and request a certificate and then install the same.
I tried doing the same from firefox , but not sure how to proceed further. We dont have any WEP key etc. I tried fiddling with vaious other methods like LEAP, importing the certificate from windows etc.
I've been having issues setting up the wireless interface on my Ubuntu server (command-line only, no GUI) and I can't seem to get it working. It seems as though the card is recognized, the drivers are installed and the interface is up, but it fails to connect. I have no idea where I'm going wrong. I have WPA and a MAC filtering setup on my wireless router. An exception has been made for this PC's MAC address and I've manually entered the connection details into /etc/network/interfaces.
I'm trying to install an Ubuntu cloud on my home network - I've been following this guide. When I arrived at STEP 6: Install an image from the store PART 3: Click on the Store tab I get the following error message on the page: Error 60: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
[notice] Digest: generating secret for digest authentication ... [notice] Digest: done [warn] RSA server certificate CommonName (CN) `srvspam' does NOT match server name!?
I have a certificate froma CA that I want to use with Mutt. I have been using this certificate to sign emails in thunderbird and I don't want to send emails from mutt without it. I looked on Mutts website, but I wasn't able to make heads or tails of it. I found something on Google about gpgp certificates and wanted to know if that would be the same type of instructions.
I'm interested in the possibility of setting up a sort of hotspot using my laptop that will act as both a DHCP and DNS server in the hopes of running a softroot on my Nook e-reader.
According to the instructions posted here: [URL] I need to use Windows 7 and a couple different applications. Windows 7 is not an option for me, as I have Ubuntu Netbook 10.10 installed and would like to keep it that way. Can anyone offer any clues as to what I would need to use?
I was trying to set up my computer as a wireless AP/router. I am using a D-Link wireless dongle for the wireless network. I have ensured it can be put in the master mode. I followed the instructions on [url] and steps seemed to have been completed without a problem.
However, the wireless signal is not being broadcasted. I cannot see it on my phone or my laptop. The only difference I see is that my Ubuntu installation is the desktop version instead of the server edition. However, I don't think that should be the issue!

I suspect this down state to be an issue but the command ip link set wlan1 up is not doing anything
I just got a new printer (photosmart premium) and I have tried to set it up in the printing config but the listed printers do not include mine..do I have any other options?
I just installed Ubuntu 10.04 and am very excited about using it for the first time. I am very new to computers and stuff though so I don't have much of a clue as to what I'm doing. Although it installed fine, for my wireless connection it says "device not ready". What does this mean and how do I connect to the internet?
I have spent the last 24 hours trying to work a wireless bridge (a D-Link DAP-1522) into my network configuration. It would connect to our gateway here at home (some 2WIRE piece of garbage AT&T hands out, but I digress), and two computers (an Ubuntu Desktop and an Ubuntu Server) would connect via the bridge.
The bridge SEEMS to connect to the router, and indeed, the Ubuntu Desktop PC is able to access the internet. The server, however, is not, and neither computer can communicate with the other (ping, SSH, etc.) furthermore, the router recognizes the presence of these two computers on some level, but does not seem to know their IP addresses (I assume this is related to the computers' inability to communicate).
Before I get too far into this, here are a few links/items for the sake of clarity. The first is a shoddy diagram of my (proposed) network topology, for all of you out there who, like myself, understand things visually:[url]
This is the output from running "ifconfig eth0" on the Ubuntu Desktop PC, which sits behind the bridge. The PC is connected, and can ping hosts across the Internet, but can only ping the router locally (that is, it can't ping any other device in the house, on either side of the bridge):
Code:
The router uses wireless encryption, not MAC addresses, to restrict access/traffic, and all wireless devices (including the bridge) have been provided with the proper credentials. There shouldn't be any devices being denied access on account of their MAC address. In fact, the router's control panel lists the PC and the Server among the recognized devices (even lists their MAC addresses), but provides no IP address and always considers the two computers to be "offline." And yet, I am writing this very post from the Ubuntu PC. Sigh.
I am very comfortable with computers, and reasonably comfortable with Ubuntu/Linux and the Linux command line -- I've been using the operating system for just over a year now -- but networking issues have always been perched right on the edge of my understanding. In short, it's likely this issue has more to do with me than it does with the hardware itself (although the more forums I browse, the more I start to doubt this bridge...).
I installed 10.10, I'm using a HP tower with a cisco usb ae1000 modem. I have been on Linux all of 12 hours. I had installed on a old laptop, and hard wired to the router. I really liked the OS. And Long short I killed the laptop, literally.
So I partitioned the family tower, but I cannot connect wirelessly. And to run hard wire to the router would mean a complete tear down of my desk and set up in the living room area, and that will not help out the marriage long/short term.
on the internet connection and I gone through the panels trying to set up the connection but no luck. I'm running Vista and Ubuntu 10.10. I using vista to post here now.
How do I get it to find the wireless router and set up my connection without being hardwire to the router itself.
I have a Sonicwall access point, which I am able to set up through the interface, but after that I am unable to achieve a connection through my wireless card. I have a good understanding of everything involved, but really have no hands on experience when it comes to networking.
Also, I should have mentioned that @ the interface for the Sonicwall it said that "no DNS server had been specified", but I set it up for DHCP, and I thought my ISP is using PPPoE (which I also thought used DHCP).
I've been using Ubuntu for a while, but I have never tried to set up a wireless device with it. I have no idea where to even begin. I've done a search of the forums but wasn't able to glean much from it.
I have a Toshiba Satellite L655-S5061 laptop and dual-boot Windows 7 and Kubuntu Lucid Lynx. Windows detects and connects to the wireless network just fine, but in Kubuntu it will detect the network but can't connect to it. Sometimes Network Manager will say it's connected, but Konqueror can't load any websites. Plugging in an ethernet cable doesn't give me access to the internet, either.
I just installed Ubuntu 10.04 . Need to get my wireless router working on my HP laptop. Have been using a Linksys WRT54G Router with windows and it is working properly. Tried setting up in NetworkManager but it does not work.
When looking at things in the Ubuntu terminal it says the network is DISABLED.
I'm trying to set up a wireless access point and router using Ubuntu 10.10. My machine has an Atheros AR5001X+ PCI card, and eth0 is connected to an ADSL modem.After literally days and days of going in circles, I'm hoping that somebody here can help get me on track.This sort of works, though I had to go through some other contortions to get the madwifi driver to finally compile on my machine.At this point, I can see and connect to the WAP, but nothing more. When I try "sudo /etc/init.d/networking restart",
I also have a second problem, which is that I want to use WebMin to manage this server, but I cannot figure out how to get the ADSL client module configured -- RP-PPPoE version 3. It seems to expect to work with pppoe-start, pppoe-stop, and pppoe-status, but when I try to run pppoe-status it says "Link is down", even though my ppp connection is actually working.Is is possible to use the WebMin ADSL client module with Ubuntu? I spent a lot of time trying to get pppoe-start, stop, etc. working but it was a complete mess and never seemed to behave. Finally, I just put the ppp startup commands into the /etc/network/interfaces file and that worked, but now the pppoe-* commands no longer seem to function.
I am new to linux and just set up my wired network, still a few kinks that needs to be sorted out. When setting up a wireless connection, what is needed for a basic p2p network. Wireless connection from one laptop to another to enable sharing? What I have done was set up a wireless network on my windows machine, connect to it using ubuntu. (this is all done with the built in wireless adapters, no routers). The connection is made, both the windows and ubuntu machines say connected, but none of the computers show up in the networks directory?
I am trying to set up the wireless with the latest version of Ubuntu. I can connect to the internet with the ethernet but wireless connections do not even show up. My wireless card is a Intel WiFi Link 1000 BGN and perhaps that is the problem. I am not sure if that will work. I am also using VMware and perhaps it just doesn't work with VMware.
When I type in iwlist scan it just comes up with: lo interface does not support scanning and eth0 interface does not support scanning. When I search for available drivers it says no proprietary drivers are in use on this system. Then it has VMware virtual ethernet driver and VMware virtual machine communication interface.
I used a self assigned certificate openssl req -new -outform PEM -out smtpd.cert -newkey rsa:2048 -nodes -keyout smtpd.key -keyform PEM -days 365 -x509 i followed configurations from th below website [URL].. On my outlook client p.c`s whenever connecting for the first it pops up a message telling mi tht my certificate on my server cannot be verified then it continues after click yes.
How do i do away with tht message other thn buying trusted certificate Or refer me to a good site with Ubuntu mail server configuration which makes uses of mysql
these are the lines in my /etc/dovecot/dovet.conf file ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem
I have a Linksys WAG54G2 Router - this is set up and was working fine with Xp and my Apple I phone.I have just changed over from XP to Ubuntu, and am having difficulty in configuring wireless settings to accept UBUNTU.The hard wired Ethernet connection works fine.
I'm living at a friend's right now, and he's got a wireless access point in the house that I set my laptops wlan0 interface to route through the eth0 to my desktop. It's been working fine for internet sharing and internal networking ( ssh and ftp ) between the laptop and the desktop, but there's a problem with both subnets being able to communicate with each other, and I haven't been able to solve it with DNAT either.
The wireless access point is 192.168.0.1 and has its own lan on 192.168.0.0/24 of which my laptop is 192.168.0.5. I setup the little subnet I created by routing with the laptop to 192.168.1.0/24 and my desktop is 192.168.1.50. With shorewall I can configure iptables to DNAT all of my ssh traffic destined to 192.168.0.5 to 192.168.1.50, but the problem seems to occur when ssh on my desktop fails to connect rather than the DNAT failing.
Using iptraf I've seen that all of the routing does work properly, because I can see on the connection in iptraf that only the SYN packet is being sent from a 192.168.0.x address, there is no ACK packet sent back. I believe this is because in the connection dialog it always shows a 192.168.0.x ip as the source of the connection, but I don't have a route to 192.168.0.0/24 from 192.168.1.0/24 setup and I'm unsure of how to do so.
I'm pretty much in over my head because I don't know what is wrong, I thought it should work like this. Everything else from port configurations, to the configurations of the software itself seems fine so I don't think it's anything like that preventing a connection, but I can't think of what it would be aside from the lack of routing between each subnet.
Is there anyway to just add a route so that 192.168.1.0/24 and 192.168.0.0/24 can communicate with each other directly? I know there should be, I'm just not at all sure how it would be done.
I'm trying to follow the instructions here to get my dell wireless NIC working in CentOS. I've got to step 3 but when I run the make command.But it does exist, as a link pointing to ../../../usr/src/kernels/2.6.18-194.el5-i686.
I've used windows all of my life, and never really looked at Linux, so thought it would be a good time to see outside of the box! I installed Ubuntu 9.10 a couple of weeks ago after reading a few Linux Newbie books and deciding it would be the best distro for me. Being completely new with Linux it's proving difficult doing certain things which I would have done with a couple of clicks in Windows, however I've managed to get past some of the problems after hours of searching and messing about. I managed to set my wireless network up, and with a great struggle my wireless printer using cups- which now seems to be printing fine over the network, its IP is 192.168.0.105. However even after reading lots of info and tutorials on Forums & Blogs nothing seems to work regards to my scanner (which is an all-in-one printer SX515W).
The information is completely overwhelming. I've been told to use iscan with the network plugin which I downloaded from [URL] after installing and running image scan or xscan the printer would scan for a couple of seconds and then it would stop, and I'd have to reset my printer. I read the documents supplied, blogs, and forums telling me to do certain things such as:
Like I said, being new to Linux I'm completely lost with what I'm doing or what I should be listing here! This is my last resort really, if I still can't get this thing working I may just give up because it's so stressfull!
I have a 64 bit laptop and i am using the 64 bit version of ubuntu 10.10. i am wanting to setup a lexmark x4650 printer which has wifi built in and can do wireless printing. i have the driver from lexmark installed but it is the i386 version which i know is the 32 bit version. and i know that 32 and 64 bit versions don't work so well together. i've gone through all kinds of help on these forums and for some reason when go to print a test page, it comes back with an error statement. i will have to try it again so i can post it verbatim.
i have a similar thread in the 64 bit thread so if it can be locked or deleted and have just this one, that would be cool. this same printer is not connected to any computer for it's wireless printing ability. it is a stand alone but all of my families laptops can use it since they have the software on theirs. they are using windows 7 which is what i have also, but i am switching to linux since i am not a fan of microsoft at all. i despise everything they do. i love linux and the community around it and i just want to get this printer setup so i can make the last and final switch. this is the only thing holding me up.
how to set up wireless networks. The technical language is foreign to me. My notebook maybe described as follows:
Make and Model: SONY VAIO FW490 Processor: Intel� Core™ 2 Duo Processor P8700 (2.53GHz) RAM: 4GB DDR2-SDRAM Graphics card: ATI Mobility Radeon™ HD4650 graphics card with 512MB vRAM.

It came pre-installed with Windows Vista Home Premium but now I have Fedora 11 (w/ Gnome) as the only OS. The router that I am using with an Ethernet cable connected to my laptop is a Netgear 54Mbps Wireless Router WGR614 v7 connected to a Motorola Surfboard Cable Modem. Both worked right out of the box and now I have wired Internet access. RCN is my ISP. I would like to avoid using the Ethernet cable connecting my laptop to the router.
This is what I have done so far:
1. Gone to System>Administration>Network
2. Clicked "New" then chose "Wireless connection" from the list
3. Chose Intel Corp. Wireless WiFi Link 5100 (wlan0) from list. The other option was "Other Wireless Card".
I don't know what to do after this. What should I choose in the windows entitled "Configure Wireless Connection" and "Configure Network Settings" ? I chose Ad-Hoc for mode and entered an SSID name even though I have no explanation for taking these actions. As for the other settings, I simply went with whatever was already selected. At the moment, I lose Internet access when I disconnect the Ethernet cable. I see other wireless networks when I click the network icon on the top right corner of the screen. I don't know how to make my router appear on that list if that's necessary.
I have a requirement of using a wildcard certificate for 5 subdomains running under apache httpd server and 1 subdomain under tomcat.Is there any possibility of using the single wildcard certificate both in tomcat and apache
I have recently installed Fedora 10 onto my PC, dual booting with XP, and I am fairly new to linux. I have been trying to connect to my wireless network, but cannot even get Fedora to recognise my wireless adapter (Belkin N1 +MIMO). I have tried to follow a few tutorials that go through either the ndiswrapper method or by using native drivers. Because I don't have an internet connection on Fedora, I have to boot into XP to download the files for either ndiswrapper or the native drivers, rather than installing using the terminal.I downloaded the ndiswrapper RPM, and it failed because of an 'unexpected error', and when using the tarball, it could not find the makefile. The native drivers did not install because of unresolved dependencies.
I just installed Fedora again, after a long absence. I have been using XP. I am having issues setting up my wireless card Linksys WMP54G. For some reason the card has been recognized, and the interface is there. But I have tried every walk-trough known to Google, and it still won't work. I have been using the GUI tools, but they don't work. I have also been using the command line walk through, and they aren't working either. Does anyone know which files I need to set and what the process would be?
