  • Can Ubuntu be installed in a subdirectory of another Linux variant?

    - by Reid
    I have access to (but not root on) a compute server which is running a Linux distribution that is a few years old. I'd much prefer to use a current Debian-like flavor. Thus, I'm wondering if it is possible to install Ubuntu (or stock Debian) in one of my directories, and use the Ubuntu programs and libraries in preference to what comes with the server. I would need to access arbitrary parts of the server's filesystem, not just the parts under the Ubuntu install. I log in by SSH, so there's no desktop environment needed. But, I would like to be able to use X programs.

  • How to simulate a USB plug?

    - by Nicolas Delvaux
    I have an app that implements some automations when an USB key is plugged. While developing, I have to test it in a specific environment (derivative from Debian Squeeze). The app subscribe to HAL events via DBUS. The problem is: my desk is on the third floor while my test machines are in the basement. I would really like to have a way to simulate a USB plug. usbip does not work on Ubuntu. I can't manage to use the g_mass_storage module on Ubuntu (I lack the dummy_hcd module) and in Debian. Maybe it is possible to simulate a dbus call? My work station is on Ubuntu 12.04.

  • Flickering/Flashing screen problem related to keyboard

    - by LeandroCR
    This will seems quite bizarre but that's a huge problem for me, I'm facing it for a long time since Ubuntu 12.04. My Ubuntu/Linux Mint/Debian (Unity/Gnome) always starts flickering after using the computer for a while, I always thought this had something to do with the video board. I have an Vostro 3550 (Radeon 6xxx/Intel Onboard). First I realized that when I was navigating trough an website, when i selected with the mouse a combo, the combo closed it self automatically then the screen starts flickering. The i realized when i was trying to make the login in the terminal (crtl + alt + f1) a strange character appears, like: ^@ repeatedly. When i keep CRTL pressed the system never flickers! I have absolutely no problem using Windows. What can i do? There is no such thing as Keyboard driver on Dell Support. I would love to use Ubuntu only, but this is very annoying. Problem happens on Ubuntu 12.04, .10 and 13.04 Linux Mint 15 (Cinnamon) Debian Live with Gnome

  • Grub - multiple distros

    - by kveidem
    I had Ubuntu 12.04 BETA installed on my entire HD. Then I decided to also install Linux Mint Debian Edition 121204 (LMDE). With gparted I shrunk my /home to make room for one more distro I created the partitions needed for LMDE, but figured I could use the same swap I installed LMDE - no errors. During install I selected to install GRUB to /dev/sda Grub shows Linux Mint Debian Edition, but no sign of Ubuntu The new LMDE install will not boot I can use LMDE from USB stick, which is what I use right now My Ubuntu /home has data that is not backed up (must recover) If I can boot back into Ubuntu to back up I am OK again. Please help. From gparted (sda8 and sda9 is the new ones after shrinking sda7) /dev/sda1 ext4 20 GB Flags: boot /dev/sda2 extended 912 GB dev/sda5 ext4 20 GB dev/sda6 linux-swap 4 GB dev/sda7 ext4 585 GB dev/sda8 ext4 20 GB dev/sda9 ext4 285 GB

  • MySQL is killing the server IO.

  • Netcat (nc) traditional package for RHEL 6.x?

    - by HTTP500
    I'm trying to use the Percona Apache Monitoring [Cacti] Template for Memcached. They do indeed warn that you can't use the openbsd version of the package and provide a solution for Ubuntu/Debian users, i.e.: You need nc on the server. Some versions of nc accept different command-line options. You can change the options used by configuring the PHP script. If you don’t want to do this for some reason, then you can install a version of nc that conforms to the expectations coded in the script’s default configuration instead. On Debian/Ubuntu, netcat-openbsd does not work, so you need the netcat-traditional package, and you need to switch to /bin/nc.traditional... Since the RHEL 6.x version indeed comes from openbsd (confirmed by rpm -qi nc) how does one go about getting this installed on RHEL/CentOS? Anyone else running these Percona templates on RHEL/CentOS? What did you do? alien the Debian package? Update 1: FWIW, I tried to use GNU netcat by compiling it from source but it doesn't seem to have the exact options required by the Cacti template either (i.e. there is no analogy for -C or -q1 so it seems) Update 2: I alien[ed] the netcat-traditional_1.10-38_amd64.deb package to make a .tgz and it does produce a binary "nc.traditional" and that version has the -q option but no -C Cheers

  • fail2ban log parsing too slow on Raspberry Pi - options? [migrated]

    - by Gordon Morehouse
    I'm running fail2ban on a Raspberry Pi at 950MHz which I cannot overclock further. The Pi is occasionally subject to SYN floods on particular ports. I've set up iptables to throttle the rate of SYNs on the port of interest; when the throttle limits are exceeded, hosts which send SYNs are dropped into the REJECT chain and the particular SYN packet which exceeded the limit is logged. fail2ban then watches for these logged SYNs and, after seeing a few, temporarily bans the host for a short time (this is a transient issue in the app I'm working with). The problem is that the SYN floods can occasionally reach rates which are too fast for fail2ban to keep up with; I'll see 20-40 log messages per second, and eventually fail2ban falls behind and becomes ineffective. To add insult to injury, it continues consuming a LOT of CPU as it tries to catch up. I have verified that DROP chained packets from hosts already banned by fail2ban are not logged, and thus do not add to its load. What are my options here? I have a few ideas, but no clear path forward. Could I make the log-parse regex "easier" so it takes fewer cycles? Would using iptables --log-prefix to put a token near the start of the log message, and/or otherwise simplifying/altering the fail2ban regex help? Here is the current fail2ban config line containing a regex: failregex = kernel:.*?SRC=(?:::f{4,6}:)?(?P<host>[\w\-.^_]+) DST.*?SYN Is there a faster way for fail2ban to watch for the packets exceeding the limits than parsing kern.log? Could fail2ban be run under PyPy instead of CPython with minimal nonstandard wizardry (the OS is Raspbian 7, so, mostly Debian 7)? Is there something better than fail2ban that I could use to watch for the packets which exceed the SYN limits, and after N exceeds in X seconds, temporarily put the offending IP into the iptables DROP bucket, and take it out when the ban timer expires? Again, I'd vastly prefer a solution that uses as much software available in Debian as possible, though I can build Debian packages in a pinch.

  • Virtualization and best hardware sharing scenario for me

    - by azera
    Hello, Following this thread on super user, I now want to start installing all my vm on the hardware. As a remainder, i have a (powerful enough) server on which i want to install 3 OS: there is a debian (general dev testbed purposes), an ipcop (network control/firewall) and a freenas (local network file sharing). I'm wondering which scenario would be the best for me and if I will be able to share the hardware to do what i want; either a - install an hypervisor like the free vmware esx and all three vms in it, or b - install debian, and the other two running inside it with virtual box My need being that: the ipcop should handle all network traffic to the internet, meaning all traffic from my main computer but also all traffic from the other two vm the freenas shares should be accessible from the other two vm and my main computer too i don't really care about the debian access, i only need to access it from my main computer, not the other vms Will I need to install additionnal network cards for each vm or can they all share the same one happily ? (right now I have two, one linking the server to my router [which only ipcop is gonna use] and one linking it to my switch [which i would like all three to use]) As for harddrives, I was going to use 1 harddrive cut in 3 partitions to install all three OSes, then add to that the freenas drives, will it be correct ? Thanks a lot for anyone who can help me, this is kind of a vast area and I'm not sure which way to go at all

  • Windows 7 network performance tuning for LAN

    - by Hubert Kario
    I want to tune Windows 7 TCP stack for speed in a LAN environment. Bit of background info: I've got a Citrix XenServer set up with Windows 2008R2, Windows 7 and Debian Lenny with Citrix kernel, Windows machines have Tools installed the iperf server process is running on different host, also Debian Lenny. The servers are otherwise idle, tests were repeated few times to confirm results. While testing with iperf 2008R2 can achieve around 600-700Mbps with no tuning what so ever but I can't find any guide or set of parameters that will make Windows 7 achieve anything over 150Mbps with no change in TCP window size using -w parameter to iperf. I tried using netsh autotuining to disabled, experimental, normal and highlyrestricted - no change. Changing congestionprovider doesn't do anything, just as rss and chimney. Setting all the available settings to same values as on Windows 2008R2 host doesn't help. To summarize: Windows 2008R2 default settings: 600-700Mbps Debian, default settings: 600Mbps Windows 7 default settings: 120Mbps Windows 7 default, iperf -w 65536: 400-500Mbps While the missing 400Mbps in performance I blame on crappy Realtek NIC in the XenServer host (I can do ~980Mbps from my laptop to the iperf server) it doesn't explain why Windows 7 can't achieve good performance without manually tuning window size at the application level. So, how to tune Windows 7?

  • Public static ip for vagrant box

    - by Numbata
    I have server (Debian Squeeze) with 1 ethernet card and 2 public static IPs (188.120.245.4 and 188.120.244.5). What I want: Setup virtual box (Ubuntu) with access via static IP (188.120.244.5). What I was trying: config.vm.forward_port - good idea: setup interface "eth1:1" with 188.120.244.5 on host-machine, and add to Vagrant file "config.vm.forward_port = hmm..?" config.vm.network :hostonly, "188.120.244.5" - not working. Was created new interface on host-machine with ip "188.120.244.1". Of course 188.120.244.1 IP isn't mine and I can't access my server via this IP. config.vm.network :bridged - I'm confused how this works :) What I have now: Not working configuration. Debian-host-machine# cat Vagrantfile Vagrant::Config.run do |config| config.vm.define :gitlab do |box_config| box_config.vm.box = "ubuntu" box_config.vm.host_name = "ubuntu" box_config.vm.network :bridged box_config.vm.network :hostonly, "188.120.244.5", :auto_config => false end end Debian-host-machine# ifconfig eth1 Link encap:Ethernet HWaddr 00:15:17:69:71:bb inet addr:188.120.245.4 Bcast:188.120.247.255 Mask:255.255.248.0 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 vboxnet0 Link encap:Ethernet HWaddr 0a:00:27:00:00:00 inet addr:188.120.244.1 Bcast:188.120.246.255 Mask:255.255.255.0 Ubuntu-virtual-machine# ifconfig eth0 Link encap:Ethernet HWaddr 08:00:27:ee:8d:0c inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 eth1 Link encap:Ethernet HWaddr 08:00:27:45:71:87 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 How I can access virtual box via public static IP from network?

  • Port Forwarding failing only to Ubuntu servers from Draytek router

    - by Rufinus
    I know this is a kinda unusal question, but Draytek support (..which is very eager to solve the issue) seems to reach its limits. Scenario: Draytek Vigor Multiwan router with current firmware. Multiple WAN IP Aliases on one of the wan ports DMZ (or port forwarding doesnt matter) from wan ip alias to internal host currently i have two internal hosts: 192.168.0.51 (Ubuntu) 192.168.0.53 (Debian) both should be accessible from outside via one of the wan ip aliases. both are accessible with their internal ip's at all times (!) If the router gots restartet, both external ips are forwarding to its internal hosts. But after a few minutes up to 2 hours, the ubuntu host is no longer reachable via its external interface. The debian hosts on the other hand is reachable. In what does ubuntu differs from debian ? I know at least of one user with the exact same problem. see http://ubuntuforums.org/showthread.php?p=10994279 Any ideas ? TIA EDIT: via ping diagnostics directly on vigor, 192.168.0.53 is pingable, 192.168.0.51 is not. but both hosts are perfectly reachable from anywhere inside the network. if i restart ubuntu networking it works again for a short time.... i'm out of ideas.. EDIT 2: after further investigation, i noticed a ping from .51 to the network (or a host in the internet) is enough to make the port-forwarding working again. So i will add an Cronjob as a "keep-alive" ping. This will solve the problem, but the reason for this behaivor is still in the dark. Thanks to all commentors.

  • MySQL is killing the server IO.

    - by OneOfOne
    I manage a fairly large/busy vBulletin forums (running on gigenet cloud), the database is ~ 10 GB (~9 milion posts, ~60 queries per second), lately MySQL have been grinding the disk like there's no tomorrow according to iotop and slowing the site. The last idea I can think of is using replication, but I'm not sure how much that would help and worried about database sync. I'm out of ideas, any tips on how to improve the situation would be highly appreciated. Specs : Debian Lenny 64bit ~12Ghz (6 cores) CPU, 7520gb RAM, 160gb disk.

  • How to make Synaptics touchpad work better on Linux?

    - by whitequark
    I have Debian Squeeze currently installed on a Samsung N250 netbook with a Synaptics touchpad. These touchpads are, generally, good, and everything works perfectly on Windows. The support is extremely sucky on Linux through. Of course it has all the cool features like two-finger scrolling, but the cursor (or whatever is a replacement for cursor when scrolling) is trembling awfully. It trembles when I just keep the finger on touchpad, it shakes awfully if the finger is close to the top of touchpad, and when I'm scrolling with it (no matter with two fingers or one), the page shakes a lot too. None of this behavior is observed even in Windows XP with just the default drivers installed. Here's the Xorg version: $ Xorg -version X.Org X Server 1.7.7 Release Date: 2010-05-04 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.32-5-686 i686 Debian Current Operating System: Linux mannaz 2.6.32-5-686 #1 SMP Fri Dec 10 16:12:40 UTC 2010 i686 Kernel command line: BOOT_IMAGE=/vmlinuz-2.6.32-5-686 root=/dev/mapper/mannaz-root ro quiet splash Build Date: 02 December 2010 01:08:37AM xorg-server 2:1.7.7-10 (Julien Cristau <[email protected]>) Current version of pixman: 0.16.4 and here is synclient -l output: http://pastebin.com/Eqa6hGXP

  • Patch management on multiple systems

    - by Pierre
    I'm in charge of auditing the security configuration of an important farm of Unix servers. So far, I came up with a way to assess the basic configuration but not the installed updates. The very problem here is that I just can't trust the package management tools on those machine. Indeed some of them did not sync with the repository for a long time (So I can't do a "yum check-updates" on Redhat for example). Some of those servers are not even connected to the internet and use an company repository. Another problem is that I have multiple target systems: AIX, Debian, Centos/Redhat, etc... So the version could be different (AIX) and the tools available will be different. And, last but not least, I can't install anything on the target system. So I need to use a script to retrieve the information and either: process it directly or save the information to be able to process it later on a server (Which may happen to run a different distribution than the one on which the information have been retrieved). The best ideas I could come up with were: either retrieve the list of installed packages on the machine (dpkg -l for example on debian) and process it on a dedicated server (Directly parsing the "Packages" file of debian repositories). Still, the problem remains the same for AIX and Redhat... or use Nessus' scripts to assess vulnerability on the installed packages, but I find this a bit dirty. Does anyone know any better/efficient way of doing this ? P.S: I already took time to review some answers to similar problems. Unfortunately Chef, puppet, ... don't meet the requirements I have to meet. Edit: Long story short. I need to have the list of missing updates on a Unix system just like MBSA on Windows. I'm not authorized to install anything on this system as it's not mine. All I have are scripts languages. Thanks.

  • LVS / IPVS difference in ActiveConn since upgrading

    - by Hans
    I've recently migrated from an old version of LVS / ldirectord (Ultra Monkey) to a new Debian install with ldirectord. Now the amount of Active Connections is usually higher than the amount of Inactive Connections, it used to be the other way around. Basically on the old load balancer the connections looked something like: -> RemoteAddress:Port Forward Weight ActiveConn InActConn -> 10.84.32.21:0 Masq 1 12 252 -> 10.84.32.22:0 Masq 1 18 368 However since migrating it to the new load balancer it looks more like: -> RemoteAddress:Port Forward Weight ActiveConn InActConn -> 10.84.32.21:0 Masq 1 313 141 -> 10.84.32.22:0 Masq 1 276 183 Old load balancer: Debian 3.1 ipvsadm 1.24 ldirectord 1.2.3 New load balancer: Debian 6.0.5 ipvsadm 1.25 ldirectord 1.0.3 (I guess the versioning system changed) Is it because the old load balancer was running a kernel from 2005, and ldirectord from 2004, and things have simply changed in the past 7 - 8 years? Did I miss some sysctl settings that I should be enforcing for it to behave in the same way? Everything appears to be working fine but can anyone see an issue with this behaviour? Thanks in advance! Additional info: I'm using LVS in masquerading mode, the real servers have the load balancer as their gateway. The real servers are running Apache, which hasn't changed during the upgrade. The boxes themselves show roughly the same amount of Inactive Connections shown in ipvsadm.

  • How to configure iptables to use apt-get in a server?

    - by segaco
    I'm starting using iptables (newbie) to protect a linux server (specifically Debian 5.0). Before I configure the iptables settings, I can use apt-get without a problem. But after I configure the iptables, the apt-get stop working. For example I use this script in iptables: #!/bin/sh IPT=/sbin/iptables ## FLUSH $IPT -F $IPT -X $IPT -t nat -F $IPT -t nat -X $IPT -t mangle -F $IPT -t mangle -X $IPT -P INPUT DROP $IPT -P OUTPUT DROP $IPT -P FORWARD DROP $IPT -A INPUT -i lo -j ACCEPT $IPT -A OUTPUT -o lo -j ACCEPT $IPT -A INPUT -p tcp --dport 22 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 22 -j ACCEPT $IPT -A INPUT -p tcp --dport 80 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 80 -j ACCEPT $IPT -A INPUT -p tcp --dport 443 -j ACCEPT $IPT -A OUTPUT -p tcp --sport 443 -j ACCEPT # Allow FTP connections @ port 21 $IPT -A INPUT -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT $IPT -A OUTPUT -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT # Allow Active FTP Connections $IPT -A INPUT -p tcp --sport 20 -m state --state ESTABLISHED,RELATED -j ACCEPT $IPT -A OUTPUT -p tcp --dport 20 -m state --state ESTABLISHED -j ACCEPT # Allow Passive FTP Connections $IPT -A INPUT -p tcp --sport 1024: --dport 1024: -m state --state ESTABLISHED -j ACCEPT $IPT -A OUTPUT -p tcp --sport 1024: --dport 1024: -m state --state ESTABLISHED,RELATED -j ACCEPT #DNS $IPT -A OUTPUT -p udp --dport 53 --sport 1024:65535 -j ACCEPT $IPT -A INPUT -p tcp --dport 1:1024 $IPT -A INPUT -p udp --dport 1:1024 $IPT -A INPUT -p tcp --dport 3306 -j DROP $IPT -A INPUT -p tcp --dport 10000 -j DROP $IPT -A INPUT -p udp --dport 10000 -j DROP then when I run apt-get I obtain: core:~# apt-get update 0% [Connecting to ftp.us.debian.org] [Connecting to security.debian.org] [Conne and it stalls. What rules I need to configure to make it works. Thanks

  • DNS redirecting to Apache

    - by leo
    I have CentOS installed on LVM, that is on Debian. There are BIND and Apache on CentOS. I need to access sites from browser on Debian with names like: 1.domain, 2.domain, etc. So I set up Apache and I can access these sites, but using /etc/hosts/ on Debian. And now I'm trying to configure bind. named.conf: zone "domain" IN { type master; file "/var/named/domain.zone"; allow-update { none; }; }; 192.168.100.1 is DNS' ip; 192.168.100.139 is Apache ip; domain.zone: $TTL 86400 @ IN SOA domain. root.domain.

Please, explain me where I'm wrong.

  • Xen HVM Windows 2008 network bridge

    - by JavierMartinz
    I have a problem with the Windows Server 2008 guest (hvm). I can't get a network interface running for him. I also have a Debian guest and it's working ok, but I can't do it with the Win2k8 guest. When I started the VM, the machine freezes and I can't connect by ssh to the host. /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 188.165.B.C netmask 255.255.255.0 network 188.165.B.0 broadcast 188.165.255.255 gateway 188.165.B.254 brctl show bridge name bridge id STP enabled interfaces eth0 8000.e840f20acc28 no peth0 /etc/xen/xend-config.sxp ... (vif-script vif-bridge) (network-script 'network-bridge') ... /etc/xen/win2k8.cfg # Networking # vif = [ 'ip=5.39.F.G,mac=yy:yy:yy:yy:yy:yy,type=ioemu,bridge=eth0' ] /etc/xen/debian.cfg # Networking # vif = [ 'ip=178.33.D.E,mac=xx:xx:xx:xx:xx:xx' ] As you can see, in the Debian guest I only have to specify an IP address and a MAC. But if I put that in the Win2k8 guest, the machine does not start. I am using Xen 4.0
