View 1 RepliesToday I was creating an Ad Hoc network for sharing internet connection and I realized it is not working. I have done it before on Ubuntu 10.10, now on 11.04 it just doesn't work. I create a new connection (Create New Wireless Network) and it is never visible to the other computers (I checked the IPv4 settings, it was Shared to Other Computers). I really do not know what is going on, my wireless card is working perfectly fine (I can connect to other network and on additional driver it is there with a green circle).

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 RelatedSo 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)"
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 Replies View RelatedI 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?
There 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.
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'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:

I have a linux domain (FEDORA CORE 1) and two laptop's which are part of my domain with windows xp pro service pack 2.I have given two ip's to both the laptop's being primary as global and secondary as local.I have configured printer in one laptop and shared.Till last week i was accessing that shared printer from my other laptop and every thing was working fine.Last week i formatted one laptop,(which dose not have shared printer) from then onwards i am not able to access my other laptop. I get the following message when i try to accessmy other Laptop,"you might not have permission to use this network resource. contact the administrator of this server to find out if you have access permission there are currently no logon servers available to service the logon request"P.S : If i have only local IP i am able to see both the systems and i am able to access my printer, this problem comes only when i add global IP to both the machines.And also i have stopped the firewall and other things.

View 9 Replies View RelatedI have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.
I'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager
i have 3 comps(running suse 11.3) and a laptop(running vista sp2). i have installed samba on all suse comps. i have a printer attached to one of the comps and it has been shared also the internet connection on that comp has been shared. all the computers are connected using lan cables through an ethernet switch. i also have a wireless router which is connected to the ethernet switch.
I am able to view all the comps on the network except the laptop running vista. all the desktops are visible on the network and are able to print and share files on the network and also connect to the internet. the laptop running vista can connect to the internet but its not visible on the network and nor can it share files across the network or access the printer.
I'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.
New SUSE 11.3 install connects to network/internet etc OK with DHCP-assigned IP address. When I switch to static IP, I can no longer ping internal network, or anything else. This works OK with SUSE 11.2 on same hardware and (as far as I can see) same setup. Some diagnostics are shown below.
Firewall
Disabling the firewall makes no difference.
Not using a network manager (can't see how to assign fixed address if I do - all greyed out).
ifup eth0:
eth0 device: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
SuSEfirewall2: Warning: no default firewall zone defined, assuming 'ext'
(not sure why the warning - eth0 is assigned to external in the firewall setup).

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

View 3 Replies View RelatedI setup this ubuntu 9.10 server (32bit), at first I did DHCP and it gave me an address, I updated and downloaded most of the packages I needed at that time.
I switched the IP from DHCP to static IP and now I cant access outside my network. with ping or to download packages. I can however login via ssh over my network.
The only changes I made were the hostname and the static IP

I purchased an Acer Aspire 7745G yesterday and installed Ubuntu as soon as I opened up the computer.
There appears to be a big problem however. Neither the wireless nor the LAN / ethernet are working.
'ifconfig -a' gives two items: lo and pan0. I believe pan0 is the bluetooth.
The wireless icon at the top right says "No network devices available". Network Tools shows the same results.
If I plug in an ethernet cord, nothing happens.
This is a fresh Ubuntu 10.04.1 downloaded this morning from ubuntu.com. I tried installing three times (USB, CD, DVD) including data checks on the disks. Same problem all three times.
I am guessing this is some kind of driver issue, but since I have no Internet access, I cannot do a Ubuntu Update and have Ubuntu find the drivers for me.
EDIT: The wireless and ethernet are working in Windows 7.
I am currently connected in a LAN, where naturally I can see in the network folder the machines connected to the LAN. Yet I need to access the LAN that exists at the WAN side of my router, see the machnes connected at it, etc. Is there a away to do it?
What I need to do is use a shared printer outside my lan, yet I need to see what IP it has in order to add it in my printer list
I'm having all sorts of problems connecting an access point to my computer, but here is one piece that I hope will get me going, if I can get it solved.My computer has two network interfaces, eth0 and eth1. eth1 connects to the cable modem and thence the world, and works fine. eth0 is supposed to connect to the access point over a private network. Here is the output from route with my IP address blotted out:

View 2 Replies View RelatedI recently installed Xubuntu 10.04 on a desktop computer. Everything works fine aside from the fact that I can't access my Dell 3010cn network printer. The printeis accessible and work flawlessly with every other computers running XP, Vista and Ubuntu 9.10I installed the drivers and configured the printer with the exact same parameters as on my 9.10 laptop. The thing is that the printer is always "offline" as if my computer could not connect to it. Also, when I try to acces its options via its fixed IP adress (192.168.1.107) through Firefox, I cannot reach the printer. However, the printer responds to every other computer in the house.What am I doing wrong? Is there a firewall in 10.04 that keeps me from accessing to the printer?
View 1 Replies View RelatedI can communicate to Windows perfectly (Internet sharing, file sharing, printer sharing, etc), but Windows controls everything, and I can't access any other Ubuntu PC, or host a printer or Internet connection. I have been fighting Samba for quite a long time, and I finally am able to access Windows shares from Ubuntu, but I want to host the shared folders (and everything else) on Ubuntu instead, because I have a bigger HD on it, and it is just a faster computer.
I tried personal file sharing and shared folders, but it doesn't work. I am also not able to access other Ubuntu PCs in the network, for printing, remote desktop, or file-sharing. All the computer are connected to the same Ethernet router. I'm using XP Home SP3, Ubuntu 10.04 x64, and a laptop running 11.04 beta 2.
I want to connect to a wireless open ad-hoc network to have internet access. It worked a while ago (1/2 year or something) but some update must have messed something up so it doesn't work any longer. Situation: There is a laptop that is running windows 7 and is connected to the internet via cabel. A open ad-hoc network is configuered with sharing of internet connection, status of the ad-hoc network is "waiting for users to connect". I want to connect with a second laptop that is running ubuntu 11.04. I can find the network and connect to it.
Problem: I cannot get any internet access while being connected to the ad-hoc network. So my questions are: how can i find out if what causes the Problem? I suspect a driver issue, but I'm not sure. required information from Howto post a wireless issue:

I am in the process of setting up my own Linux gateway/firewall using two nics eth0(external network) and eth1(internal network). The Linux gateway hands out ip addresses using dhcp3-server, and uses iptables to route the traffic correctly. Clients are able to connect and access the internet...everything is working great, HOWEVER I can't access my apache virtual hosts websites from the internal network? They work just fine if i access them from the outside world
I can type ip of the web server, 192.168.0.201 and it shows the first virtual host listed in my /sites-enables/000-default folder. but i can't use any DNS entries. I don't have any internal DNS servers running. This doesn't makes sense, because if i replace the linux firewall/router with my normal linksys wrt54G router it works just fine.
