  • Why doesn't the Ubuntu Installer see all of my hard drives

    - by atodd
    I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

  • Is there good FAT driver for FUSE? (Lightweight, not mountlo)

    - by Vi.
    FUSE filesystem list show some FuseFat and FatFuse. Both are old, FatFuse is read-only , FuseFat is non-buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself)), but it looks too big for such task. Using FUSE to mount external storage devices is good both for security and for flexibility reason: the kernel sees only block reads and writes while actual code that deals with filesystem details runs with user privileges, allowing user to use custom filesystems and preventing from kernel filesystem exploits. Is there good vfat FUSE driver?

  • How to avoid specifying full path in sudoers file?

    - by s g
    I am trying to add a NOPASSWD entry for sudotest.sh (or any script/binary that requires sudo) in my /etc/sudoers file (on Ubuntu 12.04 LTS server), but in order to make it work, I must specify the full path. The following entry works just fine: %jenkins ALL=(ALL)NOPASSWD:/home/vts_share/test/sudotest.sh The problem is that the script might move to a different directory. This seems like a great chance to use the * wildcard in the path (i.e. /*/sudotest.sh) so that my script could be in any directory but the manual states that wildcards will not match the / character when used in a path. I've confirmed that it doesn't work. I know that I can use the word ALL in place of my script, but this means there is no password prompt for any commands which seems unsafe. How do I solve this?

  • How to enable/disable authentication without password when executing commands as superuser?

    - by 44taka
    On a Fedora 19 system which I set up for somebody a while ago I noticed that no authentication is required when commands are executed as the superuser. So, for example, when running Yum Extender, configuring the firewall or running some command with sudo in the terminal, I am not asked to provide a password. (With graphical applications the authentication dialog pops up for a few milliseconds.) For better security I would like to disable this automatic (authentication-less) assumption of superuser privileges. I do not remember if or how I enabled this authentication without a password. I might have enabled it for convenience for the non-pro user of this machine, but did not do any "fancy" things (like editing config files) to do so. I did not edit the sudoer file. I just checked that. I might have checked a "Do not ask for password again" checkbox or something similar. Whatever I did, I would like to undo it and enforce authentication for superuser tasks again.

  • Configuring two subnets with two NICS. Access from a NAS to the internet

    - by archipestre
    I am having trouble configuring my NAS. I have a DSL router with WIFI (192.168.1.1) in my flatmates room. In my room I have a server with two NICS: 1) wlan0 (192.168.1.2) that connects to the DSL router via wireless 2) em1 (192.168.0.1) that connects to the NAS (192.168.0.20) with a crossover cable. I have Fedora 17 and I have enable packet forwarding. My IP configuration is as follows: WLAN0 inet 192.168.0.1 netmask 255.255.255.0 broadcast 192.168.0.255 EM1 inet 192.168.1.2 netmask 255.255.255.0 broadcast 192.168.1.255 My routing table looks like: Destination Gateway G enmask Flags Metric Ref Use Iface 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 em1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0 I have enable a static route in the DSL server: Status Network Destination Subnet Mask Interface Gateway Remove Edit Active 192.168.0.0 255.255.255.0 LAN 192.168.1.2 From my server I can ping the DSL router and the NAS. From the NAS I can ping both NICS of the server. However the NAS is unable to ping the DSL router or any address in the Internet. Any idea of what is wrong. Thank you in advance

  • /dev/null file became regular file

    - by user197719
    In our production server suddenly /dev/null became a regular file and due to this sshd service got stopped and not able to login the server. And also we tried to the below steps to configure back to character device file, rm -rf /dev/null mknod /dev/null c 1 3 As soon as we run the rm command /dev/null is being re-created as a regular file before mknod can run. We can't figure out how this happening and which component is creating this file. So until we solve this issue we are unable to create /dev/null as character device file.

  • ip6tables blocking output traffic

    - by jmccrohan
    My OpenVZ VPS is blocking outbound IPv6 traffic, but correctly filtering inbound IPv6 traffic. Below is my ip6tables-restore script. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -i lo -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p ipv6-icmp -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p udp -m udp --dport 1194 -j ACCEPT -A INPUT -p tcp -m tcp --dport 51413 -j ACCEPT -A INPUT -p udp -m udp --dport 51413 -j ACCEPT -A INPUT -m limit --limit 5/min -A INPUT -j REJECT --reject-with icmp6-adm-prohibited -A FORWARD -j ACCEPT -A OUTPUT -j ACCEPT COMMIT ICMPv6 traffic is still able to pass both inbound and outbound. When I flush these rules using -F, outbound traffic flows fine. What am I missing here? EDIT: It appears that ip6tables is marking ESTABLISHED packets as INVALID. Consequently, the outbound traffic is NOT actually being blocked. The reply packets are not allowed inbound again, hence appearing like blocked outbound traffic. Allowing INVALID packets inbound solves the outbound issue, but also renders the inbound filter useless.

  • Problems using "at" with Apache

    - by Alex Padgett
    I'm trying to use a PHP script to create at jobs, but when it comes time to execute the jobs, nothing seems to be happening. I've tried to output any errors to log files, but have had no luck. It seems obvious that it's a permissions issue, because when I set apache to run as my personal user, everything works fine. However, when I exec wget directly from PHP, everything works fine so it seems that apache has the correct permissions to use it. The problem appears to be when using at in conjunction with apache. So I need to find a way to make this work with apache running as its own user. Here is the command I'm using: echo "wget -qO- http://example.com/" | at now + 1 minute 2>&1 Any ideas? EDIT: Apache can create the at jobs, it just seems that when they execute nothing is happening.

  • permissions on upload folder not working

    - by Camran
    I have a php script which uploads images to a folder. I have these permissions on the upload folder: drwxrwxr-- 4 user user 4096 2010-06-02 16:20 temp_images Shouldn't these permissions be enough for files to be uploaded to the folder? But this doesn't work. It only works when I set the permissions to 777. "user" is added to the www-data group, still no luck. Any ideas why?

  • use ubuntu from a removable drive to work both on laptop and desktop computer

    - by moragos
    my laptop, which i run ubuntu on, is getting a bit old and i find it's getting slower and slower at running applications. My desktop computer is stronger, but I can't give up on the portability of my laptop. I was thinking of installing a HD drawer for both my laptop and desktop. and when I come home just pull the HD from the laptop and plug it into the desktop. I wanted to ask if anyone have tried it or have any inputs on the idea

  • How can I use apt-get to resolve package dependencies when there are multiple versions in the repository?

    - by user1165144
    I've package a-package.deb which depends on b-package.deb in version 1.0. Everything works fine. But now a b-package in version 1.1 gets added to the repository. I'd suspect that apt-get installs the a-package and version 1.0 of the b-package. What really happens is, that a-package won't get installed: # apt-get install a-package Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: a-package : Depends: b-package (= 1.0) but 1.1 is to be installed E: Unable to correct problems, you have held broken packages. Is there a workaround to fix the behavior? Is there other software to use, that can handle the dependencies as defined?

  • Missed something? Cant upload files to server (permissions)

    - by Camran
    I can upload files as "root" to the Ubuntu server. Then I created a user (me). Next I added the user to the group www-data. Then assigned rwx permissions to www-data. Next, when I try to upload, delete or modify files VIA FILEZILLA, I cant. But via the terminal, I can change files using sudo command. What should I do to be able to upload files without getting the "permission denied" in filezilla? If you need more input let me know. Thanks

  • is there a way to tail a log from remote server without using any user credentials?

    - by suhprano
    I run a script tailing a log in a remote server, like so: ssh userx@someip tail -f /data/current.log|python2.7 monitorlog.py There are dependencies and service requirements that disallows me to run the script off the remote server. (DB, ACLs, and path to another service is uses) Is there a way I can tail and monitor a log without using the ssh userx@someip? I thought about generating RSA keys but I think you still need a user to ssh.

  • How to write more than one line in a launcher

    - by seraex
    How can I run three commands in a launcher? My commands are cd /home/seraex/MyDoc rm MyDoc.tgz tar cfz MyDoc.tgz * which will go to my documents folder and delete old backup and make a new backup. At the moment I make a text file and then make a launcher and point it to the file, but I want to delete the file and make the launcher run the commands directly. I'm using ubuntu 10.10 ' ubuntu site says 'Unfortunately launchers do not have access to the Bash environment so you cannot just include the multi commands' when i ggole chaining in launchers. thanks, admin may delete the question '

  • How to jump back to the first character in *nix command line?

    - by clami219
    When writing a long command in the *nix command line and having to go back to the first character, in order to add something at the beginning (for instance a nohup, when you realize the process will be a long one, or a sudo, when you realize you need root permissions) it can take a long time for the cursor to make its way back to the first character... Is there a short cut that allows you to jump straight there? I'm using a mac, so Home is not an option

  • Allowing ssh in iptables

    - by sat
    I am doing iptables firewall configuration. Actually, I need to allow ssh connection only from particular IP. But, It is blocking the ssh connection. I used the below commands. sat:~# iptables -F sat:~# iptables -A INPUT -p tcp -s src_ip_address -d my_ip_address --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT sat:~# iptables -A INPUT -j DROP sat:~# iptables -nL Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT tcp -- src_ip_address my_ip_address tcp dpt:22 state NEW,ESTABLISHED DROP all -- 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination If I try to connect from src_ip_address to my_ip_address, it is blocking the connection. Even, It is blocking from my_ip_address to src_ip_address . I haven't put any rules for OUTPUT chain. What is wrong with my commands? How to allow ssh in iptables?

  • How to I configure a swap partition using swapspace

    - by jcalfee314
    I finally have the swapspace project installed and running (via init.d). The purpose is to have a dynamically re-sizing swap partition. I'm clueless however on how to use it. It has good documentation but just does not go into that last step. How to I configure a swap partition using swapspace? The process is probably the same for any 3rd party program that would provide a swap space implementation to the kernel. I know this was intended to run as a process because the project provides an init.d script.

  • Grub File Stolen ( WINDOWS and OpenSus )

    - by NESIRSUSEJ
    I have a problem with my computer. I installed OpenSus on my external, and I still have Windows on my HDD. OpenSus took the Grub file and placed it on my external, so now I have to open OpenSus to open Windows. I never got a Windows CD when I bought my computer ( I live in South Africa :) ).... I want to install Ubuntu 12.04 on my external, but then I will have to format my external in which case I will lose the Grub file causing me to lose Windows, which I can't afford to do... yet. Does anyone have an idea what I can do?

  • Using cd to go up multiple directory levels

    - by Tossrock
    I'm dealing with java projects which often result in deeply nested folders (/path/to/project/com/java/lang/whatever, etc) and sometimes want to be able to jump, say, 4 directory levels upwards. Typing cd ../../../.. is a pain, and I don't want to symlink. Is there some flag to cd that lets you go up multiple directory levels (in my head, it would be something like cd -u 4)? Unfortunately I can't find any man page for cd specifically, instead just getting the useless "builtins" page.
