Ubuntu Networking :: Nfs And Sharing Users Between Boxes
Oct 18, 2010
Ubuntu 9.10 So I have four boxes. One has all the users on it and it is the nfs-server. The other 3 are nfs-clients. I need to be able to share all users between the boxes. I have mounted the /home directory from the server onto the three clients as well as the /usr/local folder, however I am still unable to log in as anybody but the root on the clients.
I am not even sure how to search for this (I keep getting results on how to mount the home directory, and information about adding multiple users to a single box).
I'm on the road with a laptop and my wife. I can get into various networks (like my father in law's) but just to make life nicer, I'd /like/ to only have to enter the wep key once ... in my profile. For instance: I get on the network under my profile. I then log off, and my wife logs on. She has to enter the wep key in her profile. She logs off and a cousin logs on (on our anonymous account that has limited privileges) and they also need to enter the wep key. Any way to share the wep key across all accounts? I'm using network manager in ubuntu hardy.
I have a printer connected to one PC running slackware. The printer is set up to be shared through Samba and I can print to it from my Windows laptop.I would however like to use that printer from another Linux machine (running Ubuntu).Do I need to go through Samba to do this or is there a better way with it being linux-linux?Everything I've found on google relates to going from Linux to Windows unfortunately.
I want to share a directory between two fedora 12 KDE boxes, peony and dandelion. I have set it up as simple as I can ('share' level security), but it just doesn't want to play. Any idea what might cause this error? I can ping the server ok, using hostname or the IP as shown here.
I want to share files between my desktop box and my laptop either by my mains-LAN or by ethernet cable and cannot find anything on the forum to point me in the right direction. There is plenty of information to help with the installation of Apache/LAMP and the like. But is this what I need? Will I need to create logon IDs to the desktop to share files (and even the printer?).
I am using Ubuntu 9.10 desktop. I set up my main user- admin and loaded the folders of files I would be working on and the relevant additional programs. Now, I would like to set up a second user so that someone else can use the computer with access to many of my files and folders, but not all, which would defeat having a second user. I have set sharing preferences for all of my folders. I have giving most rights to my second user. Yet the second user cannot even see ANY of my folders when they sign-in.
sharing a wine installation across the system but I haven't managed to get them to work (you'd think that this is something that would have been implemented properly a LONG time ago. Crossover has a rubbish version of it but I wanted to get it to work in Wine).Here's what I did (it works insofar as office 2003 can be used but the menu entries don't (as of yet) appear in the different users' menus):
Regular install of wine, start wine on my profile and let it build all its stuff. DO NOT INSTALL ANY PROGRAMMES YET (I did the first time and it didn't work afterwards). Create user and group "wine" with disabled password/login and no home dir. Move system.reg and drive_c to /wine and chown wine:wine, chmod 0775 (both recursively, bien sur).
Add all users to the "wine" group. Make symlinks to drive_c and system.reg in my .wine directory. Copy ~/.wine to all the other users' home directories, delete user specific registration files user.reg and userdef.reg. Chown the .wine directory for each user. Install Office 2003 (for me at least) or whatever programmes you want (I've only tried this is Office 2003).
chown wine:wine /wine -R because your installation will have messed things up a bit. Now cd (in Terminal, obviously) to /wine/drive_c/users. If you ls you'll see a folder called Public and a folder with your user name (mine is "gideon"). cp your home directory (recursively again) for each of your other users who you want to be able to use wine. Chown their user folders to user_name:wine (recursively - I'm going to stop writing that, just assume it). su as each user, go into their user directory and you'll see something like this (ls -al):
I am having issues with sharing an external hard drive with other users on a computer. For example if I reboot and login with user A and then logout and login with user B, I am not able to mount the external hard drive. If I reboot and login with user B first, I can then access the external hard drive with user B but not user A. Is there a way that both users can use the drive without having to reboot every time?
I am assuming this is some sort of security issue. If I login with the second user and go to /mnt/external harddrive I get a permission error."You do not have the permissions necessary to view the contents of "External Drive"." If I login with the first user and try to set the permission it doesn't give me the ability?
We have a collection of music for the entire family. Can each user's Music folder point (for lack of a better word) to the same physical directory? Can I do this with mounts, or is there a better way?
I have an external USB hard drive at /dev/sdb1 (NTFS)
2 users: johnny, audio
for some reason this drive is mounted at /media/TREKSTOR_ with johnny as the owner. I can't seem to chown the drive to audio. If I unmount the device, and remount it, the owner is set to johnny again. I need to access this drive from the audio account.It's a 1TB drive, so I wouldn't be able to reformat it to EXT3 easily as it's almost 60% full.
- OpenSUSE (Workstation configured to log in using Active Directory Information) - First Windows Server (Domain Controller) - Second Windows Server (Provide shared folders for users to use)
How do I map domain users from second Windows Server (like \windowsserverusers<user>) to a folder (like /home/<domain>/<user>/<user_personal_folder>) in OpenSUSE computer ? It should be via samba right? Trying checking something in /etc/samba/smb.conf but couldn't find anything.
I've set up Samba under Ubuntu for windows SMB file sharing (currently unauthenticated but soon to be backed off against A.D.) This is great within Windows where l folders are available as mounted in all applications but from my Ubuntu desktop and Ubuntu laptops, we can only access network folders and files from the File browsers and bookmarks one finds in the "Places" menu. Our issue is that most (but not all) dialogue boxes don't have any options for viewing non-local files and folders. i.e. when I'm in my web browser and I go to upload a file from our local network file server to an internet location, the "Open" dialogue box cannot see any of our local network locations.
I have a box with 6 Ethernet ports. One is the main connection to the box, and the remaining are for connecting to one host each (1-1, ie, 5 different boxes connected to each of 5 ports on the box). I setup a static route to each of the hosts, and it worked. But, now it just doesn't work. There are no firewalls, etc.
Box_A: 10.2.1.200 (going to the switch to outside).It has 5 other ports: port1 (10.2.1.11) <----> Host1: 10.2.1.20 port5 (10.2.1.15) <----> Host5: 10.2.1.25 If I do, ping -I eth1 10.2.1.20, from Box_A it doesn't work. But, it used to work.
I can't think of any obvious reason. I have two Ubuntu 10.04 machines. Each has a two disc RAID array for redundancy. Both are on my class C network (192.168.1.3 and 192.168.1.5). Both can access internet through router and I can "reach" each with a windows laptop (I can ping, login via SSH, reach webmin, SAMBA, etc). However, all the sudden, I cannot reach either linux box from the other linux box. It fails "both ways," meaning I can neither ping, login via SSH, use a SAMBA resource or in any way see the "other" linux box from one. This seemed to occur about two weeks ago (maybe after an update?). I've been using Unison to sync the RAID arrays - but not, I cannot sync at all. The only thing I could think of is to check hosts.deny (and allow) which are distribution default (unchanged)...
If I traceroute to the router, I get "1 XXXXX (192.168.1.1) 0.543 ms 1.217 ms 1.204 ms." However, if I try it to the other linux box, I get "3001.294 ms !H 2001.280 ms !H 3001.264 ms !H" which evidently means host unreachable. So it can get to the router (which has the windows box which can see both linux boxes). I just can't think of any reason why/how this could happen? Not sure how what is wrong with hosts file (I have made no changes and it accepts ping/ssh, etc from windows machine). Any ideas would be greatly appreciated.
I noticed tonight when I go to Places, Network, it will bring up an icon for Windows Network, and I can drill down to my Windows box. But I can't see the other Linux box (a laptop running Kubuntu), and the same behavior occurs on the laptop when trying to view the Linux desktop. The laptop is connected wirelessly, if that makes a difference. Each box can ping the others, but I don't yet know how to browse one Linux box from the other Linux box.
Problem with this bizarre Wifi problem. I have searched and searched and cannot find a solutions. Unfortunately this affects 3 computers in my household. And as the resident amateur Linux tech support/Linux advocate, I will be held responsible if I don't figure out how to fix this quick. After some extensive playing around, this is the situation. I have this problem on Ubuntu 9.10, Mint 9 (based on Ubuntu 10.04) and PC Linux OS 2010.:
- About a week ago the wireless network I use stopped working. There was a major power failure on our block during this period. No idea if there was a connection. Since then, I have been able to connect, but I am no longer able to access the internet. I can ping my own IP and my router, but no website (niether by IP not URL).
- When I booted my computer in Windows, it connected to the internet. My neighbours (whose network I am using) are also windows users, and are able to access the internet without problems. - I have found exactly the same problem on my wife's laptop running Ubuntu 9.10 and on a Live CD of PC Linux OS 2010 - I am still able to log into all other wireless networks without problems.
I am perplexed. Is it possible for a wireless network to prevent internet access to linux computers? And inadvertently? I tried disabling IPv6 (which wasn't being used anyhow), but this didn't make a difference. I also tried manually entering an IP address and other network details into the network settings.
i have a Domain Cotroller installed on Windows & DHCP Server installed on Ubuntu. i want to give access only authenticated Users(Active Directory Users) can get IP from DHCP. No one else canis there any option available here in DHCP ???
I'm trying to set up a mini grid of linux boxes, but am quite new to setting linux up.I've installed fedora 13 on one and would like to be able to SSH in to it. All boxes are within a university network (under a proxy if that makes any difference?).I can mount a shared disc easily enough, and SSH out to other computers (that I didn't set up myself),I've tried following a few threads, temporarily taking down firewalls, disabling SELinux, messing around with iptables but can't seem to manage it.
Samba up and running on my pc. pc runs FC12 with kde. A laptop has win vista. The pc can access the shares on the laptop but the laptop has authentication issues to access the pc. Note that windows doesnt enforce authentication forincoming network connections.Using the system-config-samba util i tried to map a windows user to the unix user "feduser". The laptop (named LAPPY) has a user (lapuser) which has on windows no password.What should I tell samba config what the windows username should be? lapuser or LAPPYlapuser doesnt work because when accessing the pc via the laptop, the authentication fails. The only auth that is successful is when choosing the same winusername as the unix username.
Secondary, id like to setup the laptop so that the user doesnt have to provide a name and password, or at least not more then once in the lifetime of the laptop. Note that you cant provide an empty password to system-config-samba. How is that possible?
Strange but not really on issue imho:the samba - KDE control module(kcmshall4) (and the smb.conf) shows 2 shares: the homedirs and the data dir the samba server configurator (system-config-samba) shows only the datadir.
I run a server that is connected to several other boxes in a private network (192.168.0.0). I have had no problems previously, but upon a reinstall of Debian squeeze I have no connectivity to the private network: a ping of other addresses on that network fail. Ping and connection to outside world is fine. This box is configured similarly to another on this private network which connects successfully. I have quadruple-checked all my basic information. I post my ifconfig below of the malfunctioning device, then the ifconfig for equivalent nic on a box connected succesfully to the private network.
Questions:
1.Could it be a cable problem? (I don't see how since the cables have not been changed I do not believe since my reinstallation).
2. What about the difference in the last lines of eth1 below and eth2 of the successful box. Is it significant that the bad eth1 reads Memory:fc3a0000-fc3c0000
is this possible on 2 Linux boxes will act as a INTERNET Firewall + Filtering: 1st PC = CENTOS 5.5 functions as a firewall using iptables with two NICS 1=ETH0 connected to internet with a public ip and 1=ETH1 with ip address of 10.0.0.1 connected to the 2nd PC Centos 5.5 with squid/dansguardian with ip address of 10.0.0.2
2nd PC = Centos 5.5 functions as a squid + dansguardian internet filtering with 2 NICS 1=ETH0 with ip address of 10.0.0.2 connected to the ETH1 of the 1st PC with ip address of 10.0.0.1 and 2nd ETH1=connected to LAN (172.16.1.0/24)
does this make sense? this might be confusing but I just want to try this, to protect incoming ssh from our previous Sys admins who intended to enter the LAN 172.16.1.0/24 network. And also to confuse them that they have to pass through 10.0.0.1 - 2.
My first time installing centos server and adding it to xp home network. I am new to setting up my own network in general. I have a home windows wired ethernet xp network (simple linxs router) with 2 xp boxes and one centos5 box all connected to the same router. I just set up the centos box running tomcat on port 8080. I need to do two very basic things at this point, but am not sure what I need to do:
What do I need to do so I can: 1. Connect in firefox on one of my xp boxes and call the tomcat server running on my centos box? 2. Be able to ftp to centos box from either of my xp boxes?
I'm having a bizarre problem with FTP transfers from my CentOS 5.3 boxes, All of my CentOS boxes appear to be limited at ~10kb/s when connecting to any FTP server outside of our network. We have no network infrastructure which would cause this, however when I use a windows based machine it is able to connect fine.
I took my laptop running Vista, and rebooted it onto a CentOS 5.3 LiveCD, and same issue.
I have checked our iptables, cleared the rules, removed the kernel modules, checked CBQ/TC it looks like nothing is limiting this. Also, other protocols work fine. Both the windows and linux boxes used passive transfers for it.
Is there anything other than iptables/CBQ which would be on a out of the box install of CentOS I should check? Is there any kernel settings for NAT connections which may cause this?
I have a Mandriva linux box connected by cable to my router. When I stream audio using this box it crashes all the wireless computers on my network. There is no effect on wired computers. All but the one computer are windows (xp or vista). The affected wireless computers are not able to even find my wireless network. I have to reboot the router to get them online.
I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.
I have Mandriva One 2009.0 (192.168.1.100) on one box and Mandriva Free 2010.0 (192.168.1.118) on the other. I can ping router (192.168.1.1) from both of these boxes but I can't ping one box to the other and the other way around. What's going on?.
Do I have to change some settings in router?. Or is it firewall issue on those two machines?. Both of these boxes are connected by cable. Symbol of the router: TL-WR340G.
I've been looking around for something that can help me share files with my notebook with lucid and my desktop with windows xp...i could only find help in setting up ubuntu... i dont know how to connect to XP, setup xp for file sharing with ubuntu and share my files.
