Ubuntu Networking :: New Install Of Lucid Not Seeing Other Machine
Jan 5, 2011
Does anyone know of a decent Ubuntu networking tutorial I can work through? I'm struggling to get a new install of Lucid to see anything on my home network.
The current state of play is:
I can browse the internet and the router.
I have several laptops running Ubuntu and a NAS drive but the HP desktop PC with the new Lucid installation can't see them.
The NAS and the HP are wired to the router.
I installed Lucid because I never got Maverick to see the network either.
Lucid on my laptop can see the NAS drive over wireless.
I can see the NAS drive but not the other machines if I boot the HP into WinXP.
I'm not much good at XP networking either so perhaps that needs configuring too. A decent tutorial would be useful, especially one that doesn't assume I have Windows machines on the network as we rarely use Windows now.

I've been trying to create file sharing between my MacBook Pro and my Lucid Lynx box for time machine backups and media server purposes. I followed this guide:[URL]..Everything seems to work with these exceptions: I can see my LucidLynx box in my finder app in my Mac but only when I run these commands from Ubuntu:
Code:
sudo /etc/init.d/netatalk restart
sudo restart avahi-daemon
If I restart my LucidLynx box then I can't see anything in finder. I can't log into my LucidLynx box from finder. I don't get a bad username or password error it just tells me the connection failed. *Note if I do enter an incorrect username or password it WILL tell me it's incorrect. I've looked at this link below since some people have used it in theses forums but it's a bit dated[URL]..

I'm having trouble displaying Xwindows programs on a remote machine. If I run "ssh -X newmachine" and I login and then run a program like xclock, I get the error message:
Error: Can't open display: localhost:10.0
If I run the same command to an anothermachine which is running Ubuntu 8.04 it works fine and xclock displays on my localmachine. If I run the command "echo $DISPLAY" on newmachine, I see:
localhost:10.0
Also, I have checked and xauth is installed on newmachine. What setting I have to change on Ubuntu 10.04 to allow remote display of Xwindows programs?

If I install Citrix in Fedora (or Ubuntu) will I be able to remote in to my computers using Rdesktop or the Terminal Services clients included with Windows? Will it be faster than VNC?
When I asked about using remote dektop on Linux I was told that RDP was a proprietary MS thing, but I read it's based off Citrix and Ctrix is actually a better version of it that supports more features and different OSes and not just Windows.
I just install Fedora on my Pentium III machine (with the drive tray). So now I am running it at home and school and I need a way to remote into it...

I try to access my ubuntu machine via my Windows Machine (Samba Server on Ubuntu Machine). Anytime I try to access the machine it asks me for my password...I enter it but it says it is invalid....is there anyway to reset it? I have already tried to remove and purge everything Samba related and then tried reinstalling, but that still didn't do anything

I have an ubuntu kk laptop connected via wireless to my mixed network (xp, win7, other ubuntu), but i can not ping said machine or connect via ssh. Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

It seems whenever i create a folder it creates the folder as untitled folder, but i can't change the folder name it just says "you don't have permission to rename item" but yet i created the folder and it is there. One thing i have noticed is that once i enter a folder it won't even let me move the folder.

I have ubuntu-8.04.1-server installed on virtual machine. It works perfect. Now, I made copy of this virtual machine. I started that copied machine and it works fine, except one thing: network does not work!
I have several others VMs with freeBSD, openBSD or Windows on it, but only ubuntu machine hes network problem after coping. I tried some other VM with ubuntu on it - same problem! I downloaded VM with ubuntu - same problem.I take a look into /etc/network/interfaces file and it looks just as it should (same as before coping) but ifconfig command returns parameters for lo only (before coping there was eth0 and lo).

I am trying to establish the easiest way to share a folder from an Ubuntu machine to a Windows machine.In the past I have added things to smb.conf and that has all worked fine but what I am trying to do is to figure out what the "new user" way of doing this is so that when I am helping other people I know I am getting them to do the simplest thing.I completely removed samba and reinstalled it so that I didn't have any configuration. Right clicked on a folder and selected "Sharing Options" ticked the "Share this folder box" gave it a name and a comment and ticked the other two boxes.
When I went to the windows laptop then it kept asking for a username/password and nothing worked.Back on the ubuntu machine I did sudo smbpasswd -a [username] and created a blank password. Now from the windows machine I can access the shared folder.Is the smbpasswd step still required? It's very confusing for a new user as there is no suggestion that anything other than right clicking on the folder and choosing the options you want would be required. Is it something to do with the fact that this is an ubuntu machine that has gradually been upgraded through versions and this problem wouldn't have been there from a new install?

We are experiencing problems copying files from a server to server where the machine issuing the copy is a 32-bit lucid and the mount drive is a 64-bit server. I have no other information but the md5's are consistently different after doing a copy. The files are > 8mb.

I can set-up an ssh tunnel from machine A to Machine B:-
fred@my-linux:~$ ssh -P myport fred@myserver.homelinux.com
I can successfully logon to machine A to Machine B.
what address and port will my tunnel 'appear' on machine B? I want to send a stream back from B to A up the encrypted tunnel, not over the open network.

I have an issue with the manner in which Network Manager is configuring the network and short of ditching Network Manager I can see no solution.The issue : Getting a machine to update its machine name in the DNS serverSounds simple doesn't it I operate a FreeBSD based firewall / DHCP / DNS server, using a default Network Manager DHCP configuration the Fedora clients do not register their names with the DNS server when they obtain an address.
I have traced the communications with Wireshark and the Fedora clients are NOT supplying the PC's hostname as part of the exchange so this is NOT a DNS server configuration issue. If I uncheck the option 'Automatically obtain DNS information from provider' under the DHCP settings the Fedora clients DO register the hostname that is put into the Hostname (optional) databox. They do NOT however store the DNS server IP address or any other records defined by the DNS server.
Is there some hidden settings or is this a bug because it isn't acceptable 'DHCP' behaviour if it isn't possible to automatically set DNS server IP addresses and at the same time register the hostname during the DHCP negotiation. Before it is said I know I can use a fixed DNS IP address but am not prepared to long term, I am also not prepared to define the Fedora clients with a 'static' IP. I am similarly not interested in playing around with scripts or any other such 'frigs' to achieve what should be a standard activity - registering a host with DNS during the DHCP negotiation.

I need to access a Windows Server 2000 machine using a Linux machine via KDE, but that will migrate to Gnome. The Linux user to connect to Windows machine, you should open an application 'XYZ' automatically, and only this, denying any unauthorized access. When you close the application 'XYZ' communications (RDP?) Should be terminated. Do I need a log of accesses and possible attempts to circumvent the system and access other application.

I have a ubuntu 9.04 machine i'm using as a file server. I'm able to see that machine from any XP machine, connect to it's shares play music, movies, work off of it NO problems. But i can't view the shares from a windows 7 home edition PC (garbage). AND, from the ubuntu PC, i can't see any of the other shares on network. I get "Fail to receive share list from server".
NOTE: Originally i had this machine connected with wireless card because of location. and I was able to see all shares then - both ways (still not from Windows 7 PCs though). However, when I moved to hard wire connection, the network disappeared. I've tried changing IP addresses, changing switches, but no network. I'd like to keep it hard wire. Can anyone point me in right direction or am i missing information?

I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable. I have configured everything fine but don't know why till now can't ping!
A. Windows machine settings as follows:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.
B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :
1. /etc/sysconfig/network:
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
2. /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"
3. /etc/resolv.conf
nameserver 192.168.1.4
search locadomain
4. I restarted network service using this command:
/etc/init.d/network start
everything is fine. When checking using ifconfig command. I get the following:
eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr:........
[code]....
I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0). I did everything above and can't ping till now, when pinging from windows or Linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.

I've run into a weird problem. Two of my linux machines (A and B, both running CentOS 5.5) are connected to the same wall ethernet socket via a hub. Bothf them are configured for static IPs. The trouble is that when machine B goes offline or hits a kernel panic, machine 1 goes offline too. What I've noticed is that in this condition the "route" output from machine A does not show any entry for the default gateway either The contents of /etc/sysconfig/network-scripts/ifcfg-eth0 for machine A are:
Code:
# Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller
DEVICE=eth0

I've been running 8.04 Hardy since its first release, and was hoping to deal with its loss of support by going to 8.10 but learned that it has already been dropped.
So I'm back to installing 10.04 - and up against the bizarre choice to drop dial-up networking! Fortunately, I have my 8.04 machine still live, and I've researched it extensively without success.
The best summary of what I've done follows this post I found online:
-----QUOTE-----
I read many threads about dialup, including those on this forum; made sure to get an external hw modem [USRobotics 5637 USB, advertised as controller-based and tested to work in Linux], to avoid the softmodem/winmodem problem.
Using the 10.04 LiveCD, I installed the four .deb packages that are in poolmainwwvdial and in poolmainwwvstreams.
Now I'm stuck because I get errors when I try command line stuff, errors like "cannot open /dev/modem" and "can't find /dev/modem in /etc/fstab or /etc/mtab"
I'm confused; I've read so many threads with so much different info that I can't sort it out. Maybe I'm following info that applied to earlier versions of Ubuntu. Every error I try to fix leads to more errors. Can someone suggest a constrained, step-by-step procedure to ensure I've mounted the modem, added myself to whatever groups, and whatever else I need to do?
I know there's no wizard to make it simple, but is there a checklist or something to help me sort this out? I have the ISP info, DNS primary+secondary server numbers, phone numbers, etc. Is there a UI/graphical path, instead of command line? Had no idea this would be so difficult.

I am a little confused with the way that networking works in Ubuntu (Lucid in particular). I switch my PC on and my network magically works (ie I dont understand what is configuring everything). I do have a DHCP server, but im not sure which process/file is configuring the interface.There is no entry for my wired interface (eth0) in /etc/network/interfaces.$ cat /etc/network/interfacesauto loface lo inet loopbackDoes this means that Network Manager is then responsible for configuring this interface? How does Network Manager configure this interface (are there config files somewhere that specify settings such as static IP and duplex)?

I have two different laptops that I would like to make bootable flash drive installs for, but would then like to have at least /home on a common removable storage (either a big flash drive or USB or ethernet hard drive) to share between the two laptops (I'll only be using one laptop as a Linux box at a time). One laptop (Dell Latitude D410) is only 32 bit capable (Pentium M - I think there's a 64 bit Core 2 CPU available for the socket 479, but I don't know if the BIOS / mobo will support it). If I'm going back and forth between 32 and 64 bits, can I share /home? What else can I share - /usr or anything else?

recently I have installed a brand new machine with 11.2. Machine boots so incredibly fast so I decided to upgraded another older machine from 11.1 to 11.2. Upgrade went fine but old machine boots significantly slower. On new I see message "doing fastboot" and few seconds later KDE starts loading. Amazing. On old I just experience regular boot, speed is comparable to old 11.1.What am I missing after upgrade? Same kernel, almost same set of services. Both machines are pretty regular PCs/x86_64, however old one have faster/better hardware (more cores, more GHz, more RAM, 2 disks in software raid-0).

I cannot install 11.3 on a machine with an intel raid controller I have tried with raid 1 using the card and then setting the disks to individual raid 0 and letting suse raid them. With the card doing it the machines crashes as soon as it tries to boot the first time, with suse doing the raid I just get 'GRUB' on the screen It seems a lot of people are having similar problems, does any one have any pointers. 11.2 installs fine. I would try and do a bug report but every time I go to the page it's in Czech
