Using my laptop, I'm trying to get onto the local library's wireless network, with zero results so far.Basically, I can see the network, but when NetworkManager tries to connect it just spins for a few minutes and then rejects the connection. (Or the connection is rejected by the router) My wireless connection works fine when connecting to my WPA home network.
View 4 RepliesI've searched the forums (250 thread limit) for a fix on this, but all the questions seem unanswered or unrelated. My situation is this: I'm running Ubuntu x64 10.10 'Maverick'. I have a cablemodem connection for my Internet access. I have home network running on DD-WRT with the dreadful Linksys WRT54G series router.
My DD-WRT router is 192.168.1.1, subnet 255.255.255.0.
My Linux box is 192.168.1.61, subnet 255.255.255.0.
I have a VyprVPN connection set up successfully on Linux. Mostly everything works great, speed's fine, latency is what I expect it to be. Except... I also run an SSH server to remotely admin the box at port 22, an Apache server running over SSL at port 7001, and a Transmission web client at port 7002 (only secured by basic HTTP realms auth). All of these things worked before I got the VPN working, I'm of course using NAT at the DD-WRT router.
The endresult I am looking for, is to have the security and protection of the VPN (even if it's only perceived) for everything I do on this machine -- EXCEPT on Apache, the Transmission web panel, and the SSH server, which I want to access from the outside world. I have no firewalls running or configured, not even iptables, not even the SPI firewall on DD-WRT. All connections to the aforementioned services from the outside world timeout coming in to the Linux box. They all work from inside my home network (182.168.1.0/24). In case it's needed, he's my routing:

How I can open files through wireless network .

View 1 Replies View RelatedAs waht it says above. I can't access public wifi as any browser on every single distro i've tried (15+) won't load just stuck in perpetual loading. No error message or nothing.
Also the browser wouldn't work until i disabled ipv6 in about:config. All browsers do this. is there something i could do to disable it completely so i have a browser choice?
I am an old Ubuntu user and have just strted running F11 on my iBook. I always run system-config-samba on all my machines including my server and even on my work server which shares with windows, Linux and OSX and have found it to be perfect. I installed it straight away on the new Fedora system but It doesn't seem to be functioning the way i expected it to.
I installed system-config-samba and then set up one share folder "Public" with open read write privileges and then turned off the Fedora Firewall all together. But "public" did not become open until I entered the user password for the fedora machine. But, then I could see all folders on the Fedora machine. Even root on the fedora machine became write-able on the network. This was not the desired effect at all. I am assuming fedora is using a non system-config-samba file share system that I am unfamiliar with. what is it? and how does it work?
So I want to put some of my folders on my network. I open up nautilus and go to my home folder and right click -> properties-> share and then selected share this folder, made it so that others could modify stuff on it and have guest access (which is what I want), and changed the share name to "home". Then I clicked create share. I then went to Places->Network->******'s public files on [the name of my computer]. But then some stupid error message popped up saying:
"DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)"
I have been trying to test the use of X window forwarding over SSH in a cafe. The Cafe's WiFi requires login via a web browser. Using Fedora 11 with Gnome on a Dell Latitude D600 laptop, the wireless works just fine. I am able to use a virtual terminal to ssh to my server at home. NX client/server works also. However, when I change to Run Level 3 on the Laptop in order to use X Window forwarding, wireless networking fails to function. Will wireless networking function at Run Level 3, and if so, how is that accomplished? Also, if I get Wireless to work at Run Level 3, will I be able to login to the free public wifi using Lynx or some other text browser, as I can with IE and Firefox?
View 7 Replies View RelatedWe have to connect one PC in private network (campus) with other PC (mostly a modem in our case)in public network. Connection should be peer to peer like and we have to use C coding for establishing connection between this two systems. Is it possible if we use port forwarding or is there any other way?
View 2 Replies View RelatedThere seems to be a lot written about virtual networking but I am not sure what approach to take in my situation. My local subnet has a public block of 128 addresses. I have a virtual host running on my machine. My machine has a static address and I'd need to assign one to the guest. I have edited the guest's interface file and assigned a public address to it's eth0. However the guest cannot ping out and I can't ping in.
By default the virtual machine manager creates a virtual network (virbr0) and assigned a private address range to it. I have tried to create a new virtual network using a subnet of my public range (/31) but the manager says the range must to a minimum of 16 addresses (/4). It doesn't look possible to achieve my aims using the virtual machine manager.
In the past I have used the procedure laid out here:[URL].. which is to manually create a bridge. I am not sure that is relevant for my 9.10. I think I would have to disable the network manager if I were to do that and I am not sure how to do that.
I will try to explain a bit first about my network typology: I have one cent os 5.5 machine with 2 nics - external one 86.x.x.122 and internal one with 2 IPs: 192.168.1.1 and 89.x.x.121. The ideea is that I have a public subnet (86.x.x.120/29) of IPs which are routable only through 86.x.x.122 so I have a webserver hosted on a different machine with the IP of 89.x.x.122 and GW 89.x.x.121 - everything works perfectly fine, except that I cannot access from the internal network 192.168.1.0 / 24 the so called DMZ (roughly) - the 89.x.x.122.
What really makes me crazy is that I setup the IPtables rules correctly because I can access the webserver from the outside world but I cannot accessit from the internal network...
what I'm missing - why the 192.168.1.0/24 cannot see the 89.x.x.122 machine... What IPtables rules should I add?
I have never seen this before but to connect to the internet either wired or wireless I have to connect to a broadband connection as well. I am currently using wireless; I connect to ISP with wireless but in order to access the internet I have connect to the wireless connection through my broadband connection(This is where I enter a user name and password.). I'm not sure why this is, I have always just plugged an Ethernet cable in and the computer just knew I guess.
I am using ubuntu-10.04-netbook-i386.iso that I had put onto a USB drive. It booted fine, but when I tried accessing the internet I couldn't. I was able to connect to the ISP, but I couldn't find any settings for a broadband connection. My computer is a Acer Aspire One Netbook 250
Intel Atom

I have a network where several machines are connected through a switch. I'd like all machines to be able to read/write to/from the hard drives of the other machines. for example:
machine1 will read/write files that are on the hard drive of machine2
machine2 will read/write files that are on the hard drive of machine1
machine3 will read/write files that are on the hard drive of machine1
machine3 will read/write files that are on the hard drive of machine2
etc etc...
all of this reading/writing will be done through the terminal, and programatically. rather than SSHing into a machine to read/write files from it, I'd be happy to set up some 'conventions' on how to access hard drives of various machines. for example:
'hdd1' will refer to the hard drive of machine1 (that has the static IP of 192.168.0.1).
'hdd2' will refer to the hard drive of machine1 (that has the static IP of 192.168.0.2).
'hdd3' will refer to the hard drive of machine1 (that has the static IP of 192.168.0.3).
etc etc...
this way, when I want to read/write a file, its PATH will be something like ~/hdd1/myfile.txt; ~/hdd2/anotherfile.txt;
Today I have tested the networks at several schools in the area,and at the town hall. It is not possible to surf on www on any of these networks using a PC running Linux. My conclusion is that there has to be some kind of filtering of traffic that exclude PC's running Linux. From the same PC I can send and receive email, I can ping and trace (mtr) addresses on www, and I can view webpages that are on servers on the inside of the filtering-gateway. The filter used is InterScan Web Security Virtual Appliance from TrendMicro
I have also demonstrated for the admins at the town hall that using Linux-PC on a "clean" network, surfing is no problem. By doing these small tests I have demonstrated that Linux is not the problem.
Tomorrow I'm going to visit the network providers admins, so that they could see what happens when a PC running Linux tries to access www. What kind of things should I test to document, or find the problems? So far I have just used MTR to document slow respons, wget --no-proxy to document that www hangs and ends time out, ifconfig to show NiC settings, and route.. Could this be a problem with /etc/resolve.conf?
The network provider is the same company that refused to turn on IMAP on the exchange servers, resulting in 3 week without mail at our school. All the other schools had to upgrade Outlook in order to connect to the new exchange-server with MS MAPI settings. MS Gold partners are so nice...
Is there any one know how to deploy a remote OS installation for a host with public network address? In a LAN with private network, we can use PXE, kickstart... but what we could do with the hosts have only public ip address?
View 2 Replies View RelatedI would like be able to access packets coming off the network with the hopes of coding a primitive packet sniffer for learning purposes. I would also like to be able to piece together my own packets and send them out on my network. Eventually, I would also like to write a simple firewall so I want the capability to drop packets as well as let them pass. I assume I will have to access the kernel with some system calls to do this, any one have any information or resources that could help me on this project?

View 8 Replies View RelatedI'm using Ubuntu 10.10 since 2-3 weeks. First I tried live CD and the OS seems to be very good. So i installed it on my laptop.So far i had no problems until I tried to access the shared network folders of my Server running on MS Windows Vista and another trial PC running WindowsXP. I'm trying to solve this since 2-3 days, I haven't found a solution.1st of all my network works fine. All computers can ping each other and as the laptop had Windows XP installed the server was accessable.1st I installed the SMB4k tool with this program. I could see the computer names, but as soon as I select a Windows computer the tool searches and nothing happens.
I tried a lot of different variations of this command but in the end I receive this kind of error. I also tried to add -o user=username pass=password, nothing changed.After this I searched information about this error, some forum threads I googled are telling the SMB4K tool modifies the /etc/sudoers file and cause this error. So i tried to change it back with some kind of sudo chmod 0640 etc/sudoers but this won't work it seems I can not modify or edit thisw file using sudo.With the pyNeighbourhood tool I could only see my Laptop but not the Windows PCs.At the end I will install Linux systems on all of my PCs, but only if all my tests will pass .

Ok let's say I have Apache Webservers on 2 different machines within my network, I have http://outterABC.com setup at dyndns.org to point to my modem at home, and my router forwards Port 80 to the ServerA Machine (i.e. 192.168.0.3). I can access my webpage I setup for the Server A Machine.
But what I want to try and do is somehow access my ServerB machine's website that is on my same network. I tried something like this http://ServerB.outterABC.com and the apache page came up with something like the page wasn't available. I want to access the content of the ServerB website, but because I have only one router, i can only forward Port 80 site traffic to my ServerA machine's website. I'm sure it's a different syntax I should use but i'm just not sure what I should enter to bring up the apache root web page for the Server B website via http://outterABC.com
I tried setting up DNS A records on ServerA, but I don't think it will work with what i'm trying to do above.
This is a brand new install of 11.4. While trying to set u p for wireless, when I click on network manager it does not open. Do I need to re-install? I am using a Toshiba Satellite , dual booting with XP. The install was seamless, and picked up all my files from the previous distro. Now the big bugaboo, wireless, but I can't seem to get oout of the starting gate if I can't get to network manager?
View 2 Replies View RelatedI recently reformatted and dual partitioned to both Windows 7 as well as ubuntu 10.10. Loading works fine and Windows 7 is 100% operational. I cannot seem to get my wireless network adapter to be read by Ubuntus 'Windows Wireless Drivers' gui. Here are the steps that I have done THUS far, to make sure that we are all on the right path. Before I go any further, my wireless network adapter is an old school WUSB11 Linksys Wireless Network Adapter (running version 2.6).
1) Downloaded and installed "ndiswrapper" from ubuntu's main website. I downloaded the common, utils and ndisgtk files and installed them accordingly.
2) I extracted these three files to the desktop of Ubuntu and accessed the terminal page.
3) From terminal I typed "cd Desktop" to change the directory to the desktop.
4) Next, I typed in "Sudo dpkg -i ndiswrapper-common_1.54-2ubuntu1_all.deb
Sudo dpkg -i ndiswrapper-utils-1.9_1.54-2ubuntu1_i386.deb
Sudo dpkg -i ndisgtk_0.8.5-1_i386.deb"
5) This installed Windows Wireless Drivers gui successfully and I can access it.
6) I have downloaded the driver files for the adapter from the cisco website and searched them for the required files needed.
7) After extracting the .INF file from the "Drivers" directory named "NETUSB.SYS" (I wasn't sure if the other associated files within the same folder needed to be present together with NETUSB so I moved everything to the desktop) I typed in "sudo ndiswrapper -i NETUSB.inf". After accessing the Windows Wireless Drivers gui I have noticed that the 'netusb' driver is present yet under it, the system states "Hardware present: No". This leads me to believe that maybe I installed incorrectly or my "fireware?" is not present? I was reading through the installation guide posted on the ubuntu website that in addition to the .INF file we also need the BIN file(s)? and SYS file(s)?.. The folder with the drivers for my adapter contains a BIN file but it is not within the "Drivers" section of the folder.
9) Upon mousing over the network Icon naturally my hardware is still not present.
10) From what I gather after the system finds the hardware I am to write into the terminal

I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
my wireless home network is not recognized by my network card (RealTek RTL8190 mini PCI). The post was as follows: "I am using a new computer with Windows 7 , Athlon quad core 2.60 64 bit, 8GB RAM. Internet conection works fine with ethernet but ubuntu does not see my wireless network. card (RealTek RTL 8190 ID: 10ec:8190). Have searched this forum but unable to come up with a fix. I was looking for windows XP drivers to use Ndiswrapper but could not find a list of .inf files. My network is OK and works perfectly in windows and with my 2 laptops. Can anyone point me in the right direction? Additional info: install was done within Windows using WUBI to a separate partition on my HDD. I am new to this and thouroughly confused as to the procedure for installing the drivers if they are in fact available."
I am very frustrated in that I would like to use Ubuntu 10.04 but it is useless without internet connectability. I am new to linux and do not understand where to get the appropriate drivers or how to install them. I wish someone would answer this post and either give me a clue what to do or just say "give up" and uninstall ubunutu.
I created a key pair in kgpg on suse 11.1 kgpg version 1.2.2. i am able to encrypted and decrypted files on the pc with no issues. I then exported the public key for the key pair created above, placed on flash drive and moved to my laptop running suse 11.2.
i open kgpg version 2.2.2 and imported the key, all was good. I then passed the file encrypted on 11.1 to the 11.2 laptop and with kgpg tried to decrypt the file, but the decrypting failed. The details shows the public key i just imported and then it says gpg:decryption failed: No Secret key.
I am not clear why on it is failing and if i missed a step some where along the way.
Within the documentation of example OpenVPN setups there is a setup that shows an OpenVPN Server with two network interfaces. One interfaces is plugged into the public internet network and the second interface is plugged into the private network.
Normally I assume that it would be best to place the OpenVPN system inside the network behind the router and firewall and open only the ports needed on the router to allow access to the OpenVPN system. All other router ports would be closed. This is the first example they show. To see what I am talking about see page(s) 6-7 here -> [URL]
If one were to use the two interface public facing setup, when would that setup best be justified? I guess if you didn't want to open any ports on the router/firewall then this could be justified but then you have to lock down this public system individually instead of having it protected by the network firewall.
