Should I be able to transfer files between computers wired to the same router? Is the router bridging function used to transfer data between wired computers? I just got DSL and I'm new to networking. I have openSuse 11.4 on two computers plugged into a Belkin router. The internet connection to my ISP works from either computer. If I ping $HOSTNAME from either computer, the hostnames are different, but the IP address is the same which is that of my ISP. I only have the one router, but it has a bridging option. I don't know if it can do both bridging and routing simultaneously.
I am trying to do my graduation project, it's labeled under "linux secure router", and I should build a linux based router equipped with firewall and ACL management...Some people advice me to use linux ubuntu distribution todo this I try to do that but I don't know where to start form
I have two Ubuntu 11.04 machines connected via cable to the same D link ADSL router. how do i connect one to the other so i can see from the other computer files and transfer them using nautilus?
eth1= WAN IP= 110.88.89.66/32 Gateway= 110.88.89.65 eth0= LAN IP= 192.168.1.1/24 Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- 0.0.0.0/0 0.0.0.0/0 [Code]....
My ISP gave me IP Pool 110.88.90.68/29 to use this on my LAN. my question is how can I use this IP pool on LAN side interface. i think now its simple. 192.168.1.0 /24 is my LAN network and I can not change this, because i have near 180 PCs on my LAN.
I have an old tower that I've installed Ubuntu onto. It connects fine online with a mobile broadband stick. I also have an old wireless router knocking about, and I've been trying to network up my house wirelessly using the tower as a router, if that makes any sense. Long story short, this is my setup
Internet ==> Mobile Broadband ==> Tower ==> Wireless Router ==> Wireless Devices.
I know that it's complicated, but I'm sure that it can be done. I've tried playing around with bind9, and playing with dhcp and the like. I feel that I am close.... but no cigar. how to route all traffic from the router
- CAN connect to other computers - ssh and vnc over the home network (via D-link 524 router). - CAN get an IP address via DHCP - CANNOT get internet connections - including router at 192.168.0.1 - CANNOT even ping router (but I get an IP address - weird) - Other computers on the network CAN access internet - Live CD could not access internet

I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?
This is the results from dmesg:

I have tried:
- to set proxy settings as "Direct internet connection" - disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer - Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again. - Uninstalled Crashplan which was the last software that we installed (and it was working ok).
I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).
If I have a desktop with a USB wifi adapter connected to the internet through an ethernet cable, is it possible to create a wireless network using the adapter that will allow other users to connect to the internet through mine? I'm in a fairly low-tech place for the next few weeks and getting a router isn't likely.
If it's possible, anyone have links or instructions for how to do it?
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 installed debian to run Squid cache as a caching proxy. Ive been bashing away now for 2 days and i have managed to install squid (i first tried manually, but that did not work so i used synaptic software packager to install it (from Administration menu) That went well, thereafter i installed webamin to work with squid in a GUI
I have managed to start squid and added my range of IP addresses to the ACL list I have added the proxy restriction too.
Now, i tried to test it. I opened Iceweasel Web browser (on the same machine) and setit to use the Proxy server: localhost and port:3128 That works fine.
But when i try to change the proxy setting to my machines ip (where squid is installed) : Proxy server: 10.0.0.35 and port:3128 That does not work. Am i missing something, please help I then tried to set another windows PC on the network to: Proxy server: 10.0.0.35 and port:3128 That also does not work.
I also edited the conf file to http_access allow all, but i do not know if i have doen it correctly, but maybe there is another problem?
I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

have been trying to setup a dual boot system with ubuntu and XP running side by side on my Thinkpad T41.tried it a few times and always causes the same problem. i have 40 gig HDD, on which i create a 13 gig NTFS partition and leave the rest as free space. then install XP on the NTFS partition. no problems.
then i boot from the ubuntu disk (9.10 Karmic) and install using the "use free space" option at the partition section. ubuntu installs ok, and boots fine from GRUB 2.0. BUT when i select the XP option from GRUB's list, it starts to boot XP, i get the standard XP loading screen for three seconds and then it crashes to a blue screen critical problem, and restarts the system. when i then boot from the xp cd and go into recovery mode CHKDSK will not recognise the disk, and DISKPART shows one HDD at 35 gig which it cannot access.
this means i cant run FIXBOOT and get my xp install running again. every time i do this process it produces the same problem. tried at first with xp installed on whole HDD, and reducing the xp partition size. killed XP. then tried ubuntu first and xp second - but this caused the same inaccessible disk problem - xp would not recognise the partitions and would not install. so i slipstreamed my XP install disk to SP2 hoping this would make it recognise the partitions, but no luck there. so had to format all and repartition the 13 gig NTFS for xp. installed xp again without difficulty but ubuntu install killed my xp in the same way.
I have installed Fedora 8 on an old PC to use as a home network and I am having trouble getting a Windows PC running XP to get through to the internet, but I am able to access the internet from the Linux box with no issues. I can ping the gateway on eth0 from the Linux box, but I can't ping it from the windows PC. I am able to ping the IP address for eth0 from the Windows PC. My internet gateway is a modem/router from Hughes net. I also have a Netgear router between the Linux box and the Windows PC, but there doesn't appear to be any issues because I can ping both NICs from the Windows PC. I have pasted my Linux NIC config below. code...
I got 2 routers, one is on 192 and the other one is 10. There seems to be a problem when I am accessing 10 network from 192 although, when I do the opposite it works correctly. router configured with 192 is Huawei 510 router configured with 10 is Dlink - DIR 618 I have even tried to open 2nd interface on Huawei 510 even then it doesn't seem to work.
OpenSUSE 11.3 x64 KDE I dont know what happened it is a new install thats been running for 2 weeks . Now for some reason I can not access the internet or the router. Samba is working with Dolphin I can browse shares on local network both Windblows and Linux and ping local IP's. But I can NOT ping my router (the default gateway IP) with this box or access it with firefox so no internet. A VirtualBox of XP Pro running on this box has no problems with its bridged adapter getting out and seeing the router. I disabled the firewall, added gateway IP to network settings, disabled ipv 6 from the get go, added service provider dns's to nameservers tried opendns servers also.
im trying to connect two computers on lan.One computer has: VMWare Workstation and has Opensuse 11.3 mounted in it.The other computer has: VMWare Player and has Opensuse 11.3 mounted in it.Both computers are connected to a switch with cables.I have followed this guide in both computers:Depanati singuri calculatorul!: Opensuse 11.3 - configure local networkin order to setup a network.In one computer, if i go to: Computer---Network---Network folder, i only see one machine. When in fact i could see both of them right
my main computer hostname is home, and the others are ubuntu and eduardo.In home, I try to configure samba, downloading it with "sudo apt-get install samba" and then downloading at the synaptic manager the samba-common-bin thing.I shared my folders as ROOT in home and I cannot access from ubuntu and eduardo.Then I googled and I found this site: Quote:URL]Well... I follow all steps and I can't access these files.What I need to do to share files between these computers???
but Im thinkng of completely switiching to Ubuntu,But all of my friends are on Windows...We have a LAN of abt 100-150 .. Is there is any GUI software thru which I can see all the files which are being shared on the network by Windows PCs,I know abt Samba ...but that is only computer specific & also that is reverse way...& doing from command will be tiresome task for all PCs.
The problem started happening a few days ago. Only my linux computers are affected. Yup, that's right. My roommates running windows have zero problems.
What's the problem? Suddenly, I cannot access 2 websites: namely facebook and netflix. I just get a "waiting for facebook.com" status from my browser, and it waits there patiently until the browser finally gives up. I haven't found any other sites that give me this issue. Gmail, ....., flickr, etc all work fine.
This happens using both firefox and chrome browsers. I've tried using Ubuntu 10.10 (on my desktop) and Peppermint (distro based on ubuntu, runs on my laptop). Both machines access the internet via wifi. Both have the same problem! o_O
Both machines are up-to-date. I've rebooted many times. I've tried booting an old kernel. I haven't installed any new software lately. I've tried disabling all plugins for the browsers. I've tried power-cycling our internet modem. I've tried changing my DNS settings to use Google's Public DNS service. Nothing helps.
Actually, one small piece of information: If I put my browser in incognito mode, I can get to the "sign-in" page for both facebook and netflix. But upon putting in my credentials, I still cannot reach my custom user home page for either site.
I'm planning to take some course which will help me to compete with IT companies requisites. I'm more interested in networks in linux, and also looking for a course in networking under development side.
At school, the shop I work in has machines that run windows xp and cannot be updated to the latest SP (consider these machines "B"). This means that they are quarantined whenever connected to the network. There are also workstations that we would like to be able to connect to "B" for the sole purpose of dropping a file into a directory. These machines we will call "A" and are considered trusted.
I have No control of the school's network. I have a spare PC with two NICs as well as a 5 port switch. My thought was to use the spare PC as a gateway/router/VPN and setup an isolated "network b" consisting of all the untrusted systems. Disallow all traffic other than the VPN connection. Connect via vpn from the 4ish trusted workstations "A" to Network B. I could use mac filtering (I think) to accomplish this and disallow any computer not specifically authorized, thereby isolating the untrusted computers completely.
I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.
Alright so i just wanted to try and get remote desktop connections running so i can access files on the other computers in my house. For my first try i went after my laptop. I'm using rdesktop.
First couple times i tried i typed in
Code:
After about 15 seconds it would pop back with
Code:
I realized that my laptop's firewall was blocking the packets, so i created a custom rule that allows all TCP packets on port 3389. So i fired up rdesktop again. Now it pops back with:
Code:
But instantaneously, not after 15 seconds (not sure if thats significant or not.) I checked my firewall's log and it allowed the tcp packets.
When I try to use Nautilus to connect to another computer on my network, and I attempt to connect using the name of the Windows XP computer I am connecting to, I get the following error; Could not display "smb://computername/". Error: Failed to retrieve share list from server Please select another viewer and try again. However when I attempt to connect using the IP address on the network, it connects instantly. smb://192.168.1.101/ Why doesn't it connect using the computer's name? What am I doing wrong?
I am interested and looking forward to get a smartphone or a personal data assistant with calendar/ email/ contacts just like the iphone does.My intention is to be able to sync my smartphone's data with my home server that actually carries my PIM applications. Basically, during the day when I am not home I will modify or add/remove data from the phone. When I arrive home I would like to be able to sync my changes to my server. My laptop will be reconfigured to retrieve and sync from that server.
Proudly running with Slackware on ALL my machines (gotta love Slack!), and Apple being **** by not supporting open source and linux environment, it seems that it will be difficult to have something working out of the box and will probably require jail-breaking the device, etc.. I don't want to rely on external services such as Google calendar except for the email from Gmail.
How to design secure fault tolerant network (routers, firewall, domain servers, etc) of 300 wireless computers separated in multiple buildings and floor with multiple users for each station mainly utilizing dtp and internet software?
I'm using NFS and I have the following problem. After ~100 days, the client and server lose connection, but the client doesn't know about this, it gives no error. The problem is that the changes on the server side aren't visible on the client side.
Just installed 10.04 LTS beta on 3 computers in home. At first, two of them showed up under the network window using places. The third never did and would not find the shared printer. After all rebooted, none show up. All three can access the internet and can display a valid internal network ip address using ifconfig.
