I posted the same problem before but did not get answers, I guess due to the unattractive title. I have two Ubuntu machines, both desktop version with a server installed on top. They are both on the same network. It seems that when I restart the remote computer, I can ssh to it fine for a while but then I get the following:
Read from remote host: Connection reset by peer lost connection.
I am using "ping" on 2 computers on the same wifi network.One of them shows a bigger delay than the other consistently.I am trying to find out what may be the problem.. Can someone suggesta way to investigate this issue or isolate the problem?Both of them sending "ping" at almost the same time.First laptop (much newer laptop model)
Code:
PING www.l.google.com (64.233.181.104): 56 data bytes

I connect my laptop to my TV (1280 X 720) and mirror the images, having the same exact display on both the computer and the television. I tried doing this with another laptop (core2duo with nvidia gforce 9600) and the tv will show the desktop (not the full thing) while the computer remains the same. This is not usable. I tried using the nvidia settings application but to no avail.

I have an old computer I have set Ubuntu up on to use it to learn about web services, networking and sys admin.As a first step I have installed the LAMP packages successfully. I want to reach my ubuntu computer from my laptop through my home wireless setup.
On the server I open a browser put this in the address bar and get to the "It works!" page so assume its correct.I go to my laptop, put the same number in the browser and am told that there's a problem loading that page.I figure ok, could be security or ports or something so i ping it to see if it work on that level and it doesn't.I go to my laptop, get the ip for it and then try to ping from ubuntu to my laptop - that doesn't work either.Pinging the router from both computers works fine though.What do I do now?
I'm trying to get our linux servers to use Active Directory (AD), and have gotten our linux (RHEL 5) server to fetch users and groups from AD. Now I'd like to add computers (and groups of computers) to AD, and have our linux boxes make use of this info. Does anyone know how to get our linux-boxes to understand computers and computer group objects on AD?

Well, I ping to google, it is resolving but if I ping by hostname to other LAN computers. it gives error : unknown host.
But if i ping with IP address it is pinging.
NOTE :
1) My firewall is acting as a dns server and other windows systems are resolving it.
2) FC9 firewall is disabled.
I installed Fedora 12 on my laptop. I have a wireless connection to the internet that works fine, I attached an Ethernet cable from this laptop to a windows machine. There is a green light.
I can ping my localhost. I can ping the windows machine using it internal IP address via the router. However, the eth0 IP address does not work when I ping to it from the windows nachine. Also, I cannot ping to the windows machine using the IP address associated with the Ethernet connection.
I have a desktop computer (Ubuntu) connected to one of the LAN ports of the Cradlepoint MBR1000 router via an Ethernet cable. I also have a Verizon mobile broadband USB modem (USB760) plugged into the USB port of the Cradlepoint router.I also have a laptop (Ubuntu) with a wireless wi-fi adapter (802.11g). The laptop also has an Ethernet card but I'm not using it. The desktop computer does not have a wi-fi adapter, only the laptop does.
With the above setup, I have Internet access to both the desktop computer as well as the laptop computer, which I am well pleased with.Is there a way I can have file sharing between the desktop and the laptop, or at least ping between them, the way I have it set up? I can't use the ad-hoc method because for that to work each computer needs a wi-fi adapter. The router is using DHCP but can also be configured manually.
I got a VPN Setup, issue is, I cannot ping or talk to any other computer through an external source without typing in the FQDN so for example to ping host: chucknorris
ping chucknorris.work.com.au
rather then just typing:
ping chucknorris

i was using ubuntu 9.10 till recently when i decided to upgrade to ubuntu lucid 10.04. turns out the internet icon shows connected after fresh installation but when i try to use firefox , after an long wait it shows server not found. i did a research of my own and found that i am not able to ping even my router.using sudo dhclient eth0 doesn't recieve offers , but surprisingly when i tried dhclient eth0 in root shell with networking internet got configured very quickly and i can ping the router and any website.i forgot to mention i have a wired connection which i am trying to connect and the net is working fine with windows 7 on the same PC.
View 2 Replies View RelatedI need to connect to an FTP server that only accepts active FTP connections. (In Windows, I have to uncheck the "use passive FTP" option in Folder Options in order to connect) Is there a way to do this with Ubuntu's Connect to Server system/Nautilus?

View 2 Replies View RelatedInstalled Ubuntu 10.04 on my Sony UX280p with Intel 4965 wireless. Ubuntu detects the card without issues (as far as I can tell). I can see all access points in my area and select my access point and pair with it. I get a DHCP address from the AP (if ifconfig is to be believed) and iwconfig shows the ESSID of my AP but I can't ping the AP or any other computer on the network, nor can I ping the sony from any other computer on my network. Last year I had installed 9.04 on this computer and wifi worked out of the box without any issues.

Yesterday I moved my modem (wireless) to my living room so the PS3 detected a better signal. In doing so, I had to run a new ethernet cable from my living room where the modem is into my office where the computer is. I use ubuntu 9.10
For some reason I cannot connect to the internet now. When I scroll over the connection, it says wire connection 1 is active. I have my settings manually set. I did notice the MAC address field is blank...
I didn't have an issue before, but with changing cables and whatnot, something got messed up somehow.
My machine has Ubuntu 10.4, installed a week ago. I'm connecting to the Internet with a Wireless 3G modem, the interface is named ppp0. Additionally, I have a network card that is connected to a home router, that's eth0. Everything works fine with eth0 disabled, all my apps can access the internet correctly. But, my issue is that when i enable eth0, i can't access the internet with any app.
So why do i need eth0 anyway? The thing is that i must share my internet connection with my sister, who is also connected to our home router. I planned to give her access by installing squid on this machine and configuring her browser to connect to squid. However, since none of my apps can connect to the internet while eth0 is active (whereas squid and all other apps work fine with eth0 disabled) I can't let her connect to squid while squid is working correctly.BTW selecting "use this connection only for resources on its network" under "routes..." of the ipv4 tab of "Auto Ethernet" made it a little better. Firefox and Xchat started to work with eth0 active. Squid still doesn't work though (althought it works just fine with eth0 disabled)
I'm having a hard time installing Ubuntu 10.10 (32bits). I load the CD and everything's ok throughout the installing procedure, but when the installation is over and it says it's gonna reboot it doesn't do it!
The screen resembles a terminal with a message like "the computer is going to reboot NOW!" but it could stay like that for hours. The keyboard is locked so I can't reboot by commands, and if I press CTRL+ALT+DEL it just reprints the same message. Therefore I'm forced to turn off my computer manually.
After that, the Ubuntu desktop doesn't load. The screen shows a terminal asking for my username and password to access the computer. No graphics at all.
I want to use FTP client (for example ncftp) to connect in active mode. I have firewall (iptables) on my laptop and most of time I am behind rooter. With outgoing packets and with passive mode all is working fine.But some sites accept only active mode.I could open some port range in firewall and in rooter for active data packets, but I don't know how to solve security issues.So how should I correctly manage active ftp connection?
How can I set data port range when opening active connection with ncftp (or maybe another ftp client)?How can I limit that incoming connections to that ports range is accepted only by ncftp or else dropped?
I have installed openvpn on an ubuntu 10.04 server. I run 11.04 on my desktop. It can connect to my VPN server. The problem is, I have ZERO internet access. I cannot even ping an IP address.

I have an Acer Aspire One that worked fine with version 9.* of Ubuntu, then I upgraded to v10.1. Now Thunderbird, Evolution, and Firefox (Namoroku?) can't connect, either wirelessly or by Ethernet cable, to my ISP. I get error messages like "connection timed out" or "cannot find {link}". I can PING my ISP from Terminal, though, and I have the machine set up for dual boot with Windows 7 and Firefox works fine under Windows.
I have no idea what to look for or where to start. Any help would be greatly appreciated.

Strange things are happening today to my pc with debian squeeze 2.6.32-3-amd64 kernel.
It can connect to internet via my wirelss rt2870 driver (Ralink, Belkin usb wireless). But I cannot ping any of my other computers in the home network (served by a Belkin N+ wireless router). Other computers can ping it.
I am also connected via ethernet directly to another desktop. Last night I can access the shared file (samba windows share) in this other computer, using ethernet (disabling wireless). Today I cannot. I cannot even ping it or any computer, or itself.
I am using network manager with this interface:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
I am looking for help connecting my mainframe Linux to the active directory world.
