  • Issue#56496: Ubuntu - [server] windows can not access samba share - username case senitivity issue

    I have been attempting to make samba work on an Ubuntu amd64 server 16.04 I am building. My windows user account name is "Doug". My Ubuntu user account name is "doug". This appears to be the root issue. The related segment of the smb.conf man page is copied below: Code:       username level (G)           This option helps Samba to try and 'guess' at the real UNIX username, as many DOS clients send an all-uppercase username. By default Samba tries all lowercase, followed by           the username with the first letter capitalized, and fails if the username is not found on the UNIX machine.           If this parameter is set to non-zero the behavior changes. This parameter is a number that specifies the number of uppercase combinations to try while trying to determine the           UNIX user name. The higher the number the more combinations will be

  • Issue#271513: Ubuntu 14.04 server, BootitBM boot manager and VMWorkstation install issue

    Greetings all - ran into an issue attempting to install Ubuntu 14.04 LTS server (64) on VMWorkstation 10 after installing Terabyte Unlimited's boot manager BootitBM. Finally found one solution that I thought I would also post here in the hopes it helps someone else who runs into this issue. Their KB article #279 "Linux Installation Notes: Ubuntu" covers what I was trying to do basically (although they start with the GUI version). In the KB article, they indicate that at a minimum, you need 2 partitions for the Linux install - one for the root file system (Ext4) and one for swap. I attempted to follow the instructions and the install went well up until it came to installing GRUB at which point the installer indicated it wanted to put it in the MBR (which would have overwritten my existing boot manager) - I selected "No" and then got the screen to choose where to install it. I tried /dev/sda2 (which is where the root file system was) and the install failed. Tried a nu

  • Issue#288236: Ubuntu server and openvpn external connection issues

    Hi, I've set up an ubuntu server at home (learning my way around Linux). And I had an extra connection at my vpn service, so I tried to set it up with openvpn. In my local network this all works fine, I can reach all my services and the server gets an external ip from my vpn provider. But I can't reach my server from outside my network anymore through SSH. So what I want to achieve is that my server uses the VPN for it's external traffic, but that I still can log on on that server with tunnels to all the things I've set up there. I keep reading the same info & tutorials online, so I think I'm looking for not the wrong thing (my guess was I have to set up routing somewhere). So anyone here that wants to point me in the right direction please? :) Thank you!

    Hey, I have rig with Ubuntu 12.04.5 LTS 32bit Server edition. As we know this release is supported until April 2017. When I login it says: Code: New release '14.04.1 LTS' available. Run 'do-release-upgrade' to upgrade to it. Ubuntu Server 16.04 LTS is around the corner, what will happen when 16.04 will be released? The 'do-release-upgrade' will upgrade my 12.04 to 14.04 or 16.04? I dont really want to upgrade my 12.04 to 14.04 in this year, but if I cant upgrade to 14.04 after 16.04 released then I have to upgrade to 14.04 in this month.

  • Issue#414586: Ubuntu - [server] 16.04 Server having issues with ACLs on ZFS inside LXD containers

    I've got sort of an odd setup, here it is: Running a storage server with an array of drives on ZFS, entire server running Ubuntu 16.04. Latest updates. Several LXC containers on the server, serving various purposes, some require access to the disk array. Have given them this via either privileged containers or via ACLs and user ID mappings. Recently the mapping/ACLs just don't seem to be working right, and after some investigation, I found that after a reboot, the ACLs on ZFS don't seem to be taking effect until the directory is 'ls -l'd on the host, then the container's user is able to see it. I have an example here, since this is a sorta complex concept.. the directory is mapped into the same directory structure inside the container so it's consistent: (Inside the container, unable to cd into a directory it should have access to) Code: [email protected]:/lake/users/Chris/Projects# ls -l total 626 drwxrwxr-x 2 nobody nogroup      9 May  5  2013 3D Printer -r

  • Issue#415129: Ubuntu - Issues with upgrading and partitions

    Hello, I have a number of issues that may or may not be related. I'm running a dual boot with Windows and 14.04, and recently upgraded from Win7 to Win10 (with a fresh install, after much trial and tribulation). Now I want to upgrade 14.04 to 15.10 but running into problems. Initially I went for a fresh install from a live USB but it just stuck after selecting the download as you ugrade/install repositories options and pressing continue. Then I tried to upgrade from my current OS using system updater, which terminated because of an error (I'll go back and screenshot the details in a minute). My system partition has been getting quite full lately so I thought that might be having an impact. So my next idea was to open GParted and move things around a bit. Alas, GParted is now showing my entire disk as unallocated. Al my partitions open fine both in Windows and Ubuntu, so it doesn't seem like there's a problem with the partitions themselves - but maybe my partition tables have be

    Hey, I'm a newbie here and facing a couple issue with my server. Wanted to harden the security of my Ubuntu server but facing some issues. Googled a lot but can't see any solution of these problems. Any suggestion on how to fix these? I have installed mod_security. When I add the new symlinks to apache '/etc/apache2/mods-available/security2.conf" I get the following error: Code: Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details. When I comment the line line --> Include "/etc/modsecurity/activated_rules/*.conf" Apache starts working again. Right now I am using OWASP ModSecurity core rule set version 2.2.4 and the latest version is 2.2.9 (https://github.com/SpiderLabs/owasp-modsecurity-crs) Cas that be the cause? If yes how can I update it to the latest version?

  • Issue#515284: Ubuntu - Issues with Rythmbox and TypeCatcher since upgrading to 16.04

    Hi Since upgrading to 16.04 64-bit I've experienced a series of issues with software packaged with Ubuntu and also other software I've attempted to install. After a lot of fiddling about I managed to get VirtualBox to install and function correctly, although I had to completely remove it and then reinstall it, which is unusual - typically I rarely have issues installing new software. Anyhow, ever since the upgrade, Rythmbox hasn't worked and that is even after uninstalling it and reinstalling it. Also, because the screen fonts are a difficult to see black colour, I decided to install TypeCatcher. The installation appeared to proceed without issue, however, I can't launch it. If I try and launch it it the icon flashes in unity and then disappears. I've completely uninstalled it and purged it and reinstalled it, but it still doesn't work. I've been trying to find other posts of people experiencing similar issues, but I can't find anything. Any insights would be gratefully considered.

  • Issue#522676: Ubuntu - [server] Samba share guest access issues

    Hi all Having some unusual behaviour from samba server. With following config Code: [global]   workgroup = workgroup   map to guest = bad user   guest account = nobody   encrypt passwords = true   security = user [share]     comment = Ubuntu File Server Share     path = /srv/samba/share     guest ok = yes     read only = no     browseable = yes     public = yes     available = yes     create mask = 0777 Essentially - this works for guest access from windows machines, but doesn't work on OSX. I can get access from OSX 10.11.4 but only when I log in with username + password. Has anybody had this issue or perhaps know of a solution? I know this isn't limited to my mac, as have tested it on others. Thanks.

    Hi, in the week I updated to Ubuntu 16.04. I have Intel Sandybridge Mobile graphics. When I updated, my screen kept turning off during boot. I fixed with nomodeset. But graphic was REALLY bad. So I searched on the Internet and I found out that the only solution is a reinstall (not clean, just a reinstall). It worked but it was buggy, so I decided to clean-install. Here's a "guide" and explanation to common issues. I hope that I'm not the only who has faced this issue.t How to reinstall 1. Download/Get a Ubuntu 16.04 Live CD/USB 2.

    Hi, I've been trying to track down the source of a problem I'm having trying to print to the Brother FAX-2820 printer that I have connected to a RPi print server. I was able to get this working from Ubuntu 12.04 LTS but have not had any luck getting it to work with Ubuntu 14.04 or newer. Since Brother's wrapper / driver is only for Intel processors I set up the CUPS print server with a RAW queue on the RPi and then installed the Brother CUPS wrapper on the Ubuntu 12.04 machine. I am able to print just fine from the 12.04 machine to the Brother on the RPi. But when I try to print from the 14.04 machine to the RPi all I get are blank pages coming out of the printer. If I move the printer directly to the 14.04 machine connected via USB it prints just fine. So it is an issue with what is being sent by CUPS on the 14.04 machine to the RPi. But I'm not sure where to look for the problem. I have compared the CUPS printer.conf between the working 12.04 install and the 14.04 and everythi

  • Issue#788903: FTP issues on AWS Ubuntu 14.04 server

    Hello, I have a 14.04 running ISPConfig in an AWS server. All works well until I try and install a wordpress site. The install itself went fine, but changing themes brought up an error : cannot create directory. So, I thought I'd FTP it up. Connects ok, navigates to folder ok, but will not upload anything, saying 553: Can't open that file: Permission Demied. I tried to create a directory - same response. The FTP user is in ISPConfig The FTP user can log in The FTP User cannot ad or modify files. I went to ssh and added the ftp user as a ubuntu user. That didn't work either. Now what?

  • Issue#963043: Ubuntu - [server] In production, Do you stop most processes before upgrading the packages?

    Hello: When I need to upgrade the packages installed in my servers, I always schedule a maintenance period during which most services are turned off (I usually reboot the machines after that). This means that I've to notify my clients in advance, so that they notify their own users. It's a very tiring task. Specially when I've to upgrade the packages of a host machine that runs several virtual machines, because I need to count with the approbation of everybody. But that's not always possible and, very often, I've to postpone the upgrades for another time. In addition to that, when I reboot the machines, I've to verify that all the existing daemons have started properly, among other checks. I know that you can upgrade the packages while the applications and daemons are running. Because the old versions of the files are kept in disk (and maybe in memory) while they're in use. Indeed, that's what happens in any typical GNU/Linux system although you stop the most processes. Because alway

  • Issue#1000741: Ubuntu - Multiple Issues after Upgrading to 16.04 LTS from 14.04 LTS

    I am using the KDE desktop manager (i.e. Kubuntu). Here are the issues I have seen thus far: 1. My 14.04 KDE settings (located in ~/.kde) are not supported and/or not read by 16.04. 2. KDE Window manager occasionally crashes; this leaves the user with no ability to manage opened windows (i.e. move, resize, close, etc). New windows appear on the upper-left of the screen with the same problem in that they cannot be managed. A log-out/log-in solves the problem. 3. Audio playback of MP3 music sometimes stutters. 4. Custom IPv4 setting of wired network interface stopped working; I had to revert to using DHCP, which is not ideal for a server system. Before going to DHCP, I could not ping my router, much less anything on the outside (e.g. www.google.com). Overall, I regret going through with the upgrade. I recommend to others to forgo this version. It is quite clear that insufficient testing was conducted on the product. As for 14.04, it is supposedly supported until 2019, which should c

  • Issue#1045798: Ubuntu - Issue with Nautilus after upgrading to 16.04

    Hi everyone, I have begun to have an issue with Nautilus after upgrading to 16.04. If I use Nautilus to access my external hard drive, maximise another window, and try to return to Nautilus by clicking on its icon, the little flag thing that indicates that there is an instance of a program running will disappear and it will open another Nautilus window instead of returning to the original window. This only occurs if I am accessing files on my external hard drive, if I access files on the internal hard drive, this does not occur. Is there a way of fixing this?

  • Issue#1107215: Ubuntu - Issues since upgrading to 15.10

    I have no idea if these issues are linked 1. If I have updates set to LTS Releases only, I am not offered 16.04.1. 2 I have a red triangle exclamation icon which warns "The update information is out of date. This may be caused by a network problem, or by a repository that is no longer available. Please update manually by selecting "show updates" from the indicator menu, and watching for any failing repositories." Doing so results in "The software on this computer is up to date". 3. Boot issues. Repeated attempts to boot result in "Operating system not found". Eventually it boots. Quick Disk check reveals no errors. Any ideas?
