Ubuntu Servers :: Initial Network Setup For In Windows Group
Jun 22, 2010
I have 3 windows computers and just bought linux server. All of them are currently connected to switch. There is also Wireless AP connected to switch and ADSL router connected to switch (yeah, I know its possible to buy a 3in1 but this was bought piecemeal). ADSL is doing the DHCP and I'm not using any other advanced services.
Now, I want to route everything over the linux server. I got the 3 LAN cards for him (one for wireless, one for LAN and one for ADSL) but when I connect everything this way its not working (surprise surprise). I'm following Linux Advanced Routing & Traffic Control HOWTO but its surprisingly sparse on the topic of network setup and i dont know how to proceed now. Since the server will be a choke point I presume I need to setup DHCP server on him? First question is: can I use same netmask on all of these subnets? Ubuntu DHCP server guide uses both static and DHCP and am not sure if I should also use static on some routes or is it ok to use DHCP on all.
Also, when I was installing ubuntu server only one LAN card was used (eth2) so ifconfig shows only lo and eth2, but when I do ifconfig eth0 up and ifconfig eth1 up it doesnt look like its working. Anyway, hope somebody has some tips to point me in the right direction, primarily DHCP server setup and if I missed any steps...

This is my first server installation. I am intending to make this a basic web server for educational purposes. I have installed this server in VirtualBox, everything seemed to go fine besides the fact that I accidentally hit the enter button when I was at the opportunity to install the additional software during the initial setup. I figured that it was no big deal as I could just use aptitude to get what I needed later. My first step was to get LAMP setup. Heres where it started to seem to go wrong: I installed Apache2, however, it seems that I am unable to test it (no browser).
Code:
oliver@DrDoak:~$http://localhost/
-bash: http://localhost/: No such file or directory
oliver@DrDoak:~$
I then proceeded to install php5 again I have ran into trouble when trying to open through GEDIT.
Code:
oliver@DrDoak:~$ sudo gedit /var/www/testphp.php
sudo: gedit: command not found
oliver@DrDoak:~$

Last night I created a fresh install of Ubuntu Server 10.10. I was working through a tutorial to set up a development server for home use, and everything worked perfectly. I was able to install OpenSSH, Apache, MySQL, and PHP (and Vim) with no problems. I was also able to use "ifconfig" to determine the network address of the server and I was able to view web pages on the server from another machine on my home network, using a browser. So, everything was "peachy". [By the way: The server is connected to the router using a CAT5 cable. This is a WIRED connection] I shut the Ubuntu server down at the end of the night and, now that I have rebooted this morning, I have apparently lost the network interface. I cannot ping anything from the server. If I run ifconfig, only the "lo" configuration is listed, with the 127.0.0.1 address.

I have a couple of user accounts where each member belongs to a group i have created: Each user access the share using their own user account credentials.
How can I configure Samba in a way so that each modification done on the share gets the owner of the user and my group instead of the user and the users own group? I would also like the access rights to be 770 to each modification.
In other words, today each modification by "userA" get the owner "userA.userA" and I would like it to be "userA.MyGroup" with "rwxrwx---" permissions.

We have a small group of linux servers, currently with local logins. I want to eliminate the local logins and authenticate against the corporate AD. I've been looking at PAM - but winbind requires each machine to be added to the AD. This becomes a pain if we create new virtual or physical servers. Is it possible to have one server authenticate directly with AD, and the other servers authenticate against this server, which defers to the one server that is registered in AD?

I have joined the domain (server 2003) and can log in consistently now. Now I would like to give all the windows users in on specific group (domain power users) SUDO rights on the machines in question. I have found one way to add users on a pr. user basis, but adding 30 users will take some time.

I am very new to LVM, as well as not especially experienced at linux, and have some questions about how lvm works. A few months back I set up a server running FC10 and tried creating Logical Groups during the the initial setup. We've realized that we are not using all the available space on the physical drive, and I realized that for some reason (I'm thinking this might have been the default?), we initially created two Logical Groups (VolGroup00 and VolGroup01) and it appears two Logical volumes in each (LogVol00 and LogVol01). LogVol00 in VolGroup00 is mapped to /, and the other Group was actually unused. I figure that it would be simplest to just use all this space mapped to /, so I thought the thing to do would be to simply merge VolGroup01 to VolGroup00. I tried this:
[root@office mapper]# vgmerge VolGroup00 VolGroup01
Logical volumes in "VolGroup01" must be inactive
So after a bit of research, I tried this:
[root@office mapper]# vgchange -a n VolGroup01
Can't deactivate volume group "VolGroup01" with 1 open logical volume(s)
So apparently There's an open volume, but I don't know how to go about closing it. I removed the LogVol00 from that group, but LogVol01 won't budge.
[root@office mapper]# lvremove VolGroup01
Can't remove open logical volume "LogVol01"
So how do I go about closing this Volume? At one point, there was some output that told me LogVol01 was being used as swap space. How do I handle that?

I am trying to setup a DNS server on my local network. When I set linux clients to use it, it works as expected. However, when I set windows clients to it, the root name doesn't resolve. For example, I have a zone called daniel. On linux "anything.daniel" resolves to the correct ip as does "daniel" which is the behavior I want. However, on windows 7, "anything.daniel" resolves correctly, but "daniel" doesn't. I am new to BIND9 so my config is mostly copy and pasted. Here is my zone file for daniel (where #.#.#.# is the ip I want daniel to resolve to):
@ IN SOA ns1.daniel. admin.daniel. (
2007031001

I've tried the various tutorials and no success so far.
I can connect to the router and from there to the internet, but I cannot see any network shares. I'm connecting through wlan0. I would prefer to keep the dynamic IP address if possible.
In answer to heavyd, smbtree gives me:
WORKGROUP
\COMPUTER1
cli_start_connection: failed to connect to COMPUTER1<20> (0.0.0.0). Error NT_STATUS_UNSUCCESSFUL
\MY-LAPTOP my-laptop server (Samba, Ubuntu)
[Code]....
The data above has been anonymized for my protection.
Also I can ping them, I just can't see them via smb://.

I need to set up ssh/sftp/network shares all authenticating with AD. I want to use likewise to do the auth, but to mount the network shares I need to use an older version of samba so it can connect with likewise.How can I go about installing an older version of samba onto this new distro of the OS? I've tried installing the lenny and etch versions but I always get an error during install just saying that samba errored.

I'm trying to setup a NAS for my network, the only problem is that I can't figure out how to do it. On my network I have about 3 computers however only I only use 2 of them so I thought that maybe I could use the third computer in such a way that I could access it 24/7 from the internet as a server for all of my files (school papers, music etc etc...). The only problem is that I don't know where to get started. Both of the computers I'm currently using are Windows and the one that I,hopefully, can turn into a server is running on Ubuntu.

I am wanting to setup an office network consisting of three computers and one server. We already have the equipment ready with Vista Business pre-installed on the computers. I want to be able to create a network which allows users to use any machine as this will reduce downtime should a machine break. Also I would like user's files to be held centrally on the server which makes backups easier.
The most important element here is data backup. As like most businesses we are moving away from paper and using the computers to store important records such as customer information. If this data were to be lost, the business would come to a complete halt.
I have been looking at the idea of installing a Microsoft Small Business Server as it would be nice to have centralised control of the machines. However the cost would be over 800 which can not be justified for three machines and five users. Therefore I am turning to Linux for a alternative solution. I have previously used CentOS and Ubuntu for home use but never really gained much knowledge or experience of either.
It is my understanding that Samba can act as a Primary Domain Controller, which if I'm not mistaken is where it handles the network logins and profiles. Is this correct? I have come across many samba tutorials online but whats confusing is they are all different. Some of the tutorials involve using Kerberos and OpenLDAP. Do I need to learn about either of these? What do they do and what benefit will they bring?
Finally, I see Samba 4 is in development and is likely to bring a lot of new features which aren't available in Samba 3. Is this worth waiting for because I don't want to be upgrading everything again 6 months down the road?

I'm new around here and pretty new to ubuntu and linux in general. I am setting Up an sftp server. I set it up using openssh and it worked fine for a few months. Then recently we experienced a power outage. Now the server will boot fine, all users can login locally, but when they try to login remotely they enter their user info and then are denied with some generic network error. Again, being a noob at this I tried to trouble shoot this a little bit but I'm not quite sure what to look for. I believe the ssh service is running but I don't know what else to look for.

running a Ubuntu 8.10 Desktop in the living room with a LOT of files. I've tried all week to get this working, and can't tell where the problem is. I want to make a music share that will: Allow guests, but as read-only Allow me to mount in Windows 7 with the user 'thecheeks' Give user thecheeks read/write access to that share
I swear Samba ends up working but maybe the problem is with Windows 7. I looked at the SAMBAWiki Win 7 page and made sure my registry values were what they should have been (and they were).

I have installed Ubuntu on four machines at work and have been blown away. On my machine I have Apache setup for web development and other machines can "see" it using my IP address. I would like to have it so they can access by the name of my computer though. I have no local DNS server so I guess I need to hard code the relationship in each machine? Ideally I'd actually like to be able to use subdomains (which I use locally to avoid annoying .htaccess path problems). i.e. from another machine on the network to go to [URL].

I currently want to set up a network with 2 Ubuntu servers (mail and web) in a DMZ in order to separate them from an internal network. I want to use a dedicated Linux firewall. This firewall will have 3 network interfaces on it. One network interface will connect to the external router/modem (router and modem in one box), one interface will connect to the DMZ and the other interface will connect to the internal network. The router/modem lets you put, I think it's 1 or 2, interfaces in a DMZ.
But, when I think of any of the dedicated firewall's or servers' interfaces it doesn't make sense to me to put any of them in the router/modem's DMZ (I think it would be better for the dedicated firewall's and the servers' interfaces to have static private I.Ps ie 192.168.2.4 etc right?). What I mean is that even if, as far as the router/modem is concerned, none of the interfaces were in a DMZ, the area where the servers are would still effectively be a perimeter network and with such a set up would still be, effectively,a DMZ, right?

I am replacing a home network - Windows Server 2003 and 5 PCs (XP Pro) with UBUNTU 10.4 LTS Server and client versions. I am keeping a couple of the PCs with dual boot until I can migrate everything over (Having some issues with iTunes, Family Tree Maker, Media serving, DVD decrypt and a couple of others, but that is for another post). It was great fun getting the server up and running using only shell commands. Took me ages just to get a folder shared! Migrating the data over from NTFS to ext3 was also fun given the limited space on the partitions.
I really only want to use the server for communal network type things ... central user account maintenance, shared folders for music, video etc and data backup. I don't need it to be performing server functions on the Internet e.g. web server etc although that may come later. How I set up central user management? All the PCs are currently setup with local user ids, and it is a bit of a pain to go round each PC every time I change something.
The server is not always up, so I need to be able to log into the local PC without it being active. I was using Active Directory on Server 2003, but I don't need anything that complex really ... just 3 or 4 users to manage. I have been looking at the setup tutorial at [URL] but am not sure how relevant a lot of it is. I have SSH setup so I can login remotely, NFS is working to share the folders, but that is about all I have done so far.

I've installed mailman on 9.10, using apt-get, have apache2 setup already. However I'm getting 403 forbidden issues when trying to access [URL] I may have mucked something up as initially i jumped straight in and created a virtualhost and played around with the URL redirects. but as far as I can see, it's back to its default and it's still not working... When I try to access the page, in my apache error.log, i get this:

I'm trying to setup a Samba network share with a Fedora Directory Server backend. This will be used primarily for Windows users to authenticate before accessing the share. I am using Fedora Core 10 and have all of the latest updates installed. When I try to connect from a Windows machine, I am prompted for a username and password. I enter the username and password of the account I created in Fedora Directory Server in OU=People. The credentials are rejected. At the same time in the log file I see this:
[2009/02/24 16:50:16, 3] auth/auth_sam.c:check_sam_security(282)
check_sam_security: Couldn't find user 'Administrator' in passdb.
[2009/02/24 16:50:16, 2] auth/auth.c:check_ntlm_password(318)
check_ntlm_password: Authentication for user [Administrator] -> [Administrator] FAILED with error NT_STATUS_NO_SUCH_USER
Administrator is the user I created in Fedora Directory Server. If I perform an ldapsearch it will find the user as uid: Administrator so I know it is able to be looked up in FDS. But I'm guessing that's not the problem.

I'm putting a server together and have run into a boot up problem. (I thought about putting this in the server forum, but it might be a more generic problem that others have seen and know how to rectify.) The install seems to have gone just fine. I have the /boot partition on an internal IDE drive. The rest of that drive and another are mirrored in a Raid0 configuration (using the Linux software to do that) for data storage. The swap partition is a part of the Raid5 SCSI array that also has the / (root) partition on it.
After installation it would not finish the booting process. I suspected that GRUB didn't like all the Raid arrays and such, but it seems to be fine. I can say that because the machine will boot into rescue mode with the GUI splash screen and I have access to the whole directory tree. I have already searched on-line and following prudent advice, ran the yum update while in the chroot /mnt/sysimage mode. That only took overnight to download and most of this morning to complete. Still no dice. Used vim to delete the rhgb quiet commands in the grub.conf file so I could see where the kernel seems to be hanging.
So right after the "Creating initial device nodes" is a line about my generic PS2 wheel mouse. So I tried a USB mouse. Got more output so tried swapping out to a USB keyboard. Got a little further with more information about input devices, but still stops. Also, I tried a PCI video card just to make sure the onboard video wasn't the problem - no change. So, if someone in the Fedora community knows what loads up or is configured right after the mouse and keyboard, I might be able to figure out what's causing the computer to hang during the boot process.
