  • How to add a new entry to fstab?

    - by Roei
    I mount a device mount /dev/xvdf /mnt/mongo and verify the mount using df-h: Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7.9G 955M 6.9G 12% / tmpfs 299M 44K 299M 1% /dev/shm /dev/xvdf 20G 589M 19G 4% /mnt/mongo But now I'm trying to figure out how to make it auto mount on boot. I understand I need to add a new entry to /etc/fstab, so I perform: $ sed -i '$ a\/dev/xvdf /mnt/mongo xfs defaults 1 1' /etc/fstab But, after reboot, it seems that the auto mount didn't work. The device didn't appear in the df -h list. Should I not use the sed to add the entry? Is the entry I entered incorrect?

  • Why is my new Phenom II 965 BE not significantly faster than my old Athlon 64 X2 4600+?

    - by Software Monkey
    I recently rebuilt my 5 year old computer. I upgraded all core components, in particular from an Athlon 64 X2 4600+ at 2.4 GHz with DDR2 800 to a Phenom II 965 BE (quad core) at 3.6 GHz with DDR3 1333 (actually 1600, but testing consistently detected memory errors at 1600). The motherboard is also much newer and better. The HDD's (x3), DVD writer and card reader are the same. The BIOS memory config is auto-everything except the base timing which I overrode to 1T instead of 2T. The BIOS CPU multiplier is slightly over-clocked to 3.6 GHz from the stock 3.4 GHz. I noticed compiling Java is slower than I expected. As it happens I have some (single-threaded) Java pattern-matching code which is CPU and memory bound and for which I have performance numbers recorded on a number of hardware platforms, including my old system. So I did a test run on the new equipment and was stunned to find that the numbers are only slightly better than my old system, about 25%. The data set it is operating on is a 148,975 character array, which should easily fit in caches, but in any event the new CPU has larger caches all around. The system was, of course, otherwise idle for the test and the test run is a timed 10 seconds to eliminate scheduling anomalies. A long while ago, when I upgraded only memory from DD2 667 to DDR2 800 there was no change in performance of this test, which subjectively supports that the test cycle does not need to (significantly) access main memory, but yes it is creating and garbage collecting a large number of objects in the process of this test (low millions of matches are found for the pattern set). I am about 99.999% certain the code hasn't changed since I last ran it on 2009-03-17 - but I can't easily retest the old hardware, because it is currently in pieces on my work-bench waiting to be built into a new computer for my kids. Note that Windows (XP) reports a CPU speed of 795 MHz unless I have some thing running. With stuff running it seems to jump all over the place each time I use ALT-Pause to display the system properties, everywhere from 795 MHz to 3.4 Ghz. So why might my shiny new hardware under-performing so badly? EDIT: The old memory was Mushkin DDR2 800 with timings set for auto which should have been 5-5-5-12. The new memory is Corsair DDR3 1600, running at 1333 with timings also auto which are 9-9-9-21. In both cases they are a paired set of dual channel DIMMs. I was waiting to ensure my system was stable before tweaking with memory timings.

  • List of MD /Raid/LVM (Devices) = How to mount them without any further information available?

    - by Jens
    Hello Expets, I do not have much skills in linux and installed a system two years ago that I now had to reboot, but it seems I did not automate everything with start-scripts... My Problem: I miss some mountpoints. I have a list of my raids (excerpt:) md3 : active (auto-read-only) raid1 sda6[0] sdb6[1] 97659008 blocks [2/2] [UU] md4 : active (auto-read-only) raid1 sda7[0] sdb7[1] 250099776 blocks [2/2] [UU] and it seems md3 and md4 are NOT mounted. However i do NOT have any entries for them fstab file. What should I do next. I do NOT know which filesystem they have (most likely ext3). =Can I savely try to mount them with (mount -t ext3 /dev/md3 /mnt/mymntpoint) or will the lead to corrupted data, in case they are not ext3? What should I do next (based on the information given above). The goal is to remount these Devices again, but I do not know anything about them anymore... Thank you very much Jens

  • Ubuntu: Multiple NICs, one used only for Wake-On-LAN

    - by jcwx86
    This is similar to some other questions, but I have a specific need which is not covered in the other questions. I have an Ubuntu server (11.10) with two NICs. One is built into the motherboard and the other is a PCI express card. I want to have my server connected to the internet via my NAT router and also have it able to wake from suspend using a Magic Packet (henceforth referred to as Wake-On-LAN, WOL). I can't do this with just one of the NICs because each has an issue - the built-in NIC will crash the system if it is placed under heavy load (typically downloading data), whilst the PCI express NIC will crash the system if it is used for WOL. I have spent some time investigating these individual problems, to no avail. My plan is thus: use the built-in NIC solely for WOL, and use the PCI express card for all other network communication except WOL. Since I send the WOL Magic Packet to a specific MAC address, there is no danger of hitting the wrong NIC, but there is a danger of using the built-in NIC for general network access, overloading it and crashing the system. Both NICs are wired to the same LAN with address space 192.168.0.0/24. The built-in ethernet card is set to have interface name eth1 and the PCI express card is eth0 in Ubuntu's udev persistent rules (so they stay the same upon reboot). I have been trying to set this up with the /etc/network/interfaces file. Here is where I am currently: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.3 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 auto eth1 iface eth1 inet static address 192.168.0.254 netmask 255.255.255.0 I think by not specifying a gateway for eth1, I prevent it being used for outgoing requests. I don't mind if it can be reached on 192.168.0.254 on the LAN, i.e. via SSH -- it's IP is irrelevant to WOL, which is based on MAC addresses -- I just don't want it to be used to access internet resources. My kernel routing table (from route -n) is Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 My question is this: Is this sufficient for what I want to achieve? My research has thrown up the idea of using static routing to specify that eth1 should only be used for WOL on the local network, but I'm not sure this is necessary. I have been monitoring the activity of the interfaces using iptraf and it seems like eth0 takes the vast majority of the packets, though I am not sure that this will be consistent based on my configuration. Given that if I mess up the configuration, my system will likely crash, it is important to me to have this set up correctly!

  • Getting proper indentation using XMLBuilder in a helper

    - by Robbie
    I'm attempting to use a view helper to create some dynamic links based on if you're logged in or not. What I want returned, for sake of easy code readability, is: <ul class="right"> <li><a href="#">Login</a></li> <li><a href="#">Register</a></li> </ul> In the view helper I have this Ruby code: def loginh xm = Builder::XmlMarkup.new(:indent=>2, :margin=>4) xm.ul("class" => "right") { xm.li('class' => 'text') { xm.text("test") } } end In the view, the line that calls login helper is already indented 4 levels. Because of this, the first line gets 'skewed', so in the view I have: <%= loginh %> Which results in: <ul class="right"> <li class="text"> <text>test</text> </li> </ul> You can see it works perfectly, except for the first line. It would appear that the first line is affected by the indent before <%= loginh % is called. I can easily remedy this by removing the indentation prior to <%= loginh % - but in essence I'd be sacrificing code readability for markup readability. Which isn't what I'm looking to do. Is there any way I could remove the beginning whitespace?

  • How to fill in the network line in the ubuntu interfaces config file?

    - by matnagel
    I have to configure an ubuntu hardy server network interface. The service hoster told me that this is the network data for the machine: IP Range: 111.111.200.74 to 111.111.200.78 Netmask: 255.255.255.248 Broadcast: 111.111.200.79 Gateway: 111.111.200.73 Subnet: 111.111.200.72/29 I am only using the first IP address. I will update the /etc/hosts file with 111.111.200.74, but I am still unsure how the /etc/network/interfaces file should be. This is my plan: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 111.111.200.74 netmask 255.255.255.248 network 111.111.200.??? broadcast 111.111.200.79 gateway 111.111.200.73 As you can see I don't know how to build the network line. How would I calculate the data for the network line and what is the result? (I changed the first 2 octets of the subnet, they are not "111.111" in the real setup.)

  • udp expected behaviour not responding to test result

    - by ernst
    I have a local network topology that is structured as follows: three hosts and a switch in the middle. I am using a switch that supports 10,100,1000 Mbit/s full/half duplex connection. I have configured the hosts with a static ip 172.16.0.1-2-3/25. This is the output of ifconfig eth0 Link encap: Ethernet HWaddr ***** inet addr:172.16.0.3 Bcast:172.16.0.127 Mask:255.255.255.128 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:16 The output on H1 and H2 is perfectly matchable They are mutually reachable since i have tested the network with ping.

Since the three links have the same forced capability and the amount of arrving data speed is 10 from H1+10 from H2--20M to H3 it would be expected a bottleneck effect and, due to the non reliable nature of udp, a packet loss.

  • help setting up an IPSEC vpn from my linux box

    - by robthewolf
    I have an office with a router and a remote server (Linux - Ubuntu 10.10). Both locations need to connect to a data supplier through a VPN. The VPN is an IPSEC gateway. I was able to configure my Linksys rv42 router to create a VPN connection successfully and now I need to do the same for Linux server. I have been messing around with this for too long. First I tried OpenVPN, but that is SSL and not IPSEC. Then I tried Shrew. I think I have the settings correct but I haven't been able to create the connection. It maybe that I have to use something else like a direct IPSEC config or something like that. If someone knows of a way to turn the following settings that I have been given below into a working IPSEC VPN connection I would be very grateful. Here are the settings I was given that must be used to connect to my supplier: Local destination network: 192.168.4.0/24 Local destination hosts: 192.168.4.100 Remote destination network: 192.167.40.0/24 Remote destination hosts: 192.168.40.27 VPN peering point: xxx.xxx.xxx.xxx Then they have given me the following details: IPSEC/ISAKMP Phase 1 Parameters: Authentication method: pre shared secret Diffie Hellman group: group 2 Encryption Algorithm: 3DES Lifetime in seconds:28800 Phase 2 parameters: IPSEC security: ESP Encryption algortims: 3DES Authentication algorithms: MD5 lifetime in seconds: 28800 pfs: disabled Here are the settings from my attempt to use shrew: n:version:2 n:network-ike-port:500 n:network-mtu-size:1380 n:client-addr-auto:0 n:network-frag-size:540 n:network-dpd-enable:1 n:network-notify-enable:1 n:client-banner-enable:1 n:client-dns-used:1 b:auth-mutual-psk:YjJzN2QzdDhyN2EyZDNpNG42ZzQ= n:phase1-dhgroup:2 n:phase1-keylen:0 n:phase1-life-secs:28800 n:phase1-life-kbytes:0 n:vendor-chkpt-enable:0 n:phase2-keylen:0 n:phase2-pfsgroup:-1 n:phase2-life-secs:28800 n:phase2-life-kbytes:0 n:policy-nailed:0 n:policy-list-auto:1 n:client-dns-auto:1 n:network-natt-port:4500 n:network-natt-rate:15 s:client-dns-addr:0.0.0.0 s:client-dns-suffix: s:network-host:xxx.xxx.xxx.xxx s:client-auto-mode:pull s:client-iface:virtual s:client-ip-addr:192.168.4.0 s:client-ip-mask:255.255.255.0 s:network-natt-mode:enable s:network-frag-mode:disable s:auth-method:mutual-psk s:ident-client-type:address s:ident-client-data:192.168.4.0 s:ident-server-type:address s:ident-server-data:192.168.40.0 s:phase1-exchange:aggressive s:phase1-cipher:3des s:phase1-hash:md5 s:phase2-transform:3des s:phase2-hmac:md5 s:ipcomp-transform:disabled Finally here is the debug output from the shrew log: 10/12/22 17:22:18 ii : ipc client process thread begin ... 10/12/22 17:22:18 < A : peer config add message 10/12/22 17:22:18 DB : peer added ( obj count = 1 ) 10/12/22 17:22:18 ii : local address 217.xxx.xxx.xxx selected for peer 10/12/22 17:22:18 DB : tunnel added ( obj count = 1 ) 10/12/22 17:22:18 < A : proposal config message 10/12/22 17:22:18 < A : proposal config message 10/12/22 17:22:18 < A : client config message 10/12/22 17:22:18 < A : local id '192.168.4.0' message 10/12/22 17:22:18 < A : remote id '192.168.40.0' message 10/12/22 17:22:18 < A : preshared key message 10/12/22 17:22:18 < A : peer tunnel enable message 10/12/22 17:22:18 DB : new phase1 ( ISAKMP initiator ) 10/12/22 17:22:18 DB : exchange type is aggressive 10/12/22 17:22:18 DB : 217.xxx.xxx.xxx:500 <- 206.xxx.xxx.xxx:500 10/12/22 17:22:18 DB : c1a8b31ac860995d:0000000000000000 10/12/22 17:22:18 DB : phase1 added ( obj count = 1 ) 10/12/22 17:22:18 : security association payload 10/12/22 17:22:18 : -

  • debian gateway using iptables

    - by meijuh
    I am having problems setting up a debian gateway server. My goal: Having eth1 the WAN interface. Having eth0 the LAN interface. Allow both ports 22 (SSH) and 80 (HTTP) accessed from the outside world on the gateway (SSH and HTTP run on this server). What I did was the following: Create a file /etc/iptables.rules with contents: /etc/iptables.rules: *nat -A POSTROUTING -o eth1 -j MASQUERADE COMMIT *filter -A INPUT -i lo -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -i eth1 -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -i eth1 -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -i eth1 -j DROP COMMIT edit /etc/network/interfaces as follows: /etc/network/interfaces: # The loopback network interface auto lo iface lo inet loopback pre-up iptables-restore < /etc/iptables.rules auto eth0 allow-hotplug eth0 iface eth0 inet dhcp #auto eth1 #allow-hotplug eth1 #iface eth1 inet dhcp allow-hotplug eth1 iface eth1 inet static address 217.119.224.51 netmask 255.255.255.248 gateway 217.119.224.49 dns-nameservers 217.119.226.67 217.119.226.68 Uncomment the rule net.ipv4.ip_forward=1 in /etc/sysctl.conf to allow packet forwarding. The static settings for eth1 such as the ip address I got from my router (which I want to replace); I simply copied these. I have a (windows) DNS + DHCP server on ip address 10.180.1.10, which assigns ip address 10.180.1.44 to eth0. What this server does is not really interesting it only maps domain names on our local network and assigns one static ip to the gateway. What works: on the gateway itself I can ping 8.8.8.8 and google.nl. So that is okey. What does not work: (1) Every machine connected to eth0 (indirectly via a switch) can not ping an ip or a domain. So I guess the gateway can not be found. (2) Also when I configure my linux machine (a laptop) to use a static ip 10.180.1.41, a mask and a gateway (10.180.1.44) I can not ping an ip or domain either. This means that maybe my iptables is incorrect of not loaded correctly. Or I maybe have to configure my DNS/DHCP on my windows machine. I have not reset the windows machine net, restart the DNS/DHCP services, should I do this? I did not install dnsmasq as desribed here: http://blog.noviantech.com/2010/12/22/debian-router-gateway-in-15-minutes/. I don't think this is necessary?

  • Encoding multiple video streams with a single avconv invocation

    - by automatthias
    I played with avconv on Ubuntu and I'm now able to e.g. record the desktop with sound from a soundcard. One thing I wanted to do was recording two video inputs at the same time, for instance the desktop and from the webcam. I thought about doing something like this: avconv \ -f alsa \ -i default \ -acodec flac \ -f video4linux2 \ -r 6 \ -i /dev/video0 \ -f x11grab \ -i :0.0 \ out.mkv My thinking was that if you define multiple video inputs, and the .mkv format can handle multiple video streams, avconv will encode 2 video streams and 1 audio stream into one file. But this isn't what happens: avconv version 0.8.4-6:0.8.4-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Nov 6 2012 16:51:11 with gcc 4.7.2 [alsa @ 0x1091bc0] capture with some ALSA plugins, especially dsnoop, may hang.

  • C++, using stack.h read a string, then display it in reverse

    - by user1675108
    For my current assignment, I have to use the following header file, #ifndef STACK_H #define STACK_H template <class T, int n> class STACK { private: T a[n]; int counter; public: void MakeStack() { counter = 0; } bool FullStack() { return (counter == n) ? true : false ; } bool EmptyStack() { return (counter == 0) ? true : false ; } void PushStack(T x) { a[counter] = x; counter++; } T PopStack() { counter--; return a[counter]; } }; #endif To write a program that will take a sentence, store it into the "stack", and then display it in reverse, and I have to allow the user to repeat this process as much as they want. The thing is, I am NOT allowed to use arrays (otherwise I wouldn't need help with this), and am finding myself stumped. To give an idea of what I am attempting, here is my code as of posting, which obviously does not work fully but is simply meant to give an idea of the assignment. #include <iostream> #include <cstring> #include <ctime> #include "STACK.h" using namespace std; int main(void) { auto time_t a; auto STACK<char, 256> s; auto string curStr; auto int i; // Displays the current time and date time(&a); cout << "Today is " << ctime(&a) << endl; s.MakeStack(); cin >> curStr; i = 0; do { s.PushStack(curStr[i]); i++; } while (s.FullStack() == false); do { cout << s.PopStack(); } while (s.EmptyStack() == false); return 0; } // end of "main" **UPDATE This is my code currently #include <iostream> #include <string> #include <ctime> #include "STACK.h" using namespace std; time_t a; STACK<char, 256> s; string curStr; int i; int n; // Displays the current time and date time(&a); cout << "Today is " << ctime(&a) << endl; s.MakeStack(); getline(cin, curStr); i = 0; n = curStr.size(); do { s.PushStack(curStr[i++]); i++; }while(i < n); do { cout << s.PopStack(); }while( !(s.EmptyStack()) ); return 0;

  • Connect to wired and wireless networks at same time, Ubuntu

    - by Gary Chambers
    Currently, I have a media PC running Ubuntu 10.04 that I am trying to connect via a wired network cable directly to a NAS box, and wirelessly to the router. This works no problem after I run sudo /etc/init.d/networking restart but I can't get both interfaces to come up on system startup. My /etc/network/interfaces file reads as follows: auto eth0 iface eth0 inet static address 10.0.1.2 netmask 255.255.254.0 broadcast 10.0.1.255 network 10.0.1.0 auto wlan2 iface wlan2 inet dhcp As I say, I know this works, because I can get it to work by restarting the network interfaces, but I can't bring them both up on system startup. Does anyone know why this might be?

  • Cannot copy files from external USB HDD to computer

    - by Thomas Versteeg
    Hello I have a HDD disk connected with a USB converter to my computer. It consists of two partitions, the first one is mounted automatically and I can grab all the files from it, but the second one I have to mount manually as a root in the command line, if I try to open it with nautilus it gives an error. The drive where the problem is is drive sdb1, sdb2 has the same settings but works fine. I am using Debian Wheezy. This is the fstab: /dev/sdb1 /media/usb0 auto defaults,gid=disk,umask=0777 0 0 /dev/sdb2 /media/usb1 auto defaults,gid=disk,umask=0777 0 0 And when I try to copy the files with this command (as root) cp -vr /media/usb0/* /home/user/Videos/ I get these types of errors: cp: reading `/media/usb0/.lang/file.ext': Permission denied cp: failed to extend `/home/user/Videos/.lang/file.ext': Permission denied How can I at least copy the files to my main HDD? I don't need to adjust them I only need to copy them!

  • Bridging LXC containers to host eth0 so they can have a public IP

    - by Vianney Stroebel
    UPDATE: I found the solution there: http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#No_traffic_gets_trough_.28except_ARP_and_STP.29 # cd /proc/sys/net/bridge # ls bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-call-ip6tables bridge-nf-filter-vlan-tagged # for f in bridge-nf-*; do echo 0 $f; done But I'd like to have expert opinions on this: is it safe to disable all bridge-nf-*? What are they here for? END OF UPDATE I need to bridge LXC containers to the physical interface (eth0) of my host, reading numerous tutorials, documents and blog posts on the subject. I need the containers to have their own public IP (which I've previously done KVM/libvirt). After two days of searching and trying, I still can't make it work with LXC containers. The host runs a freshly installed Ubuntu Server Quantal (12.10) with only libvirt (which I'm not using here) and lxc installed. I created the containers with : lxc-create -t ubuntu -n mycontainer So they also run Ubuntu 12.10. Content of /var/lib/lxc/mycontainer/config is: lxc.utsname = mycontainer lxc.mount = /var/lib/lxc/test/fstab lxc.rootfs = /var/lib/lxc/test/rootfs lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 lxc.network.name = eth0 lxc.network.veth.pair = vethmycontainer lxc.network.ipv4 = 179.43.46.233 lxc.network.hwaddr= 02:00:00:86:5b:11 lxc.devttydir = lxc lxc.tty = 4 lxc.pts = 1024 lxc.arch = amd64 lxc.cap.drop = sys_module mac_admin mac_override lxc.pivotdir = lxc_putold # uncomment the next line to run the container unconfined: #lxc.aa_profile = unconfined lxc.cgroup.devices.deny = a # Allow any mknod (but not using the node) lxc.cgroup.devices.allow = c *:* m lxc.cgroup.devices.allow = b *:* m # /dev/null and zero lxc.cgroup.devices.allow = c 1:3 rwm lxc.cgroup.devices.allow = c 1:5 rwm # consoles lxc.cgroup.devices.allow = c 5:1 rwm lxc.cgroup.devices.allow = c 5:0 rwm #lxc.cgroup.devices.allow = c 4:0 rwm #lxc.cgroup.devices.allow = c 4:1 rwm # /dev/{,u}random lxc.cgroup.devices.allow = c 1:9 rwm lxc.cgroup.devices.allow = c 1:8 rwm lxc.cgroup.devices.allow = c 136:* rwm lxc.cgroup.devices.allow = c 5:2 rwm # rtc lxc.cgroup.devices.allow = c 254:0 rwm #fuse lxc.cgroup.devices.allow = c 10:229 rwm #tun lxc.cgroup.devices.allow = c 10:200 rwm #full lxc.cgroup.devices.allow = c 1:7 rwm #hpet lxc.cgroup.devices.allow = c 10:228 rwm #kvm lxc.cgroup.devices.allow = c 10:232 rwm Then I changed my host /etc/network/interfaces to: auto lo iface lo inet loopback auto br0 iface br0 inet static bridge_ports eth0 bridge_fd 0 address 92.281.86.226 netmask 255.255.255.0 network 92.281.86.0 broadcast 92.281.86.255 gateway 92.281.86.254 dns-nameservers 213.186.33.99 dns-search ovh.net When I try command line configuration ("brctl addif", "ifconfig eth0", etc.) my remote host becomes inaccessible and I have to hard reboot it.

  • Running a home mail server using dynamic dns [closed]

    - by Anand
    Hi, Is it possible to run an email server on my home box using dynamic dns? The scenario is, I want to auto cc all incoming and outgoing emails from my one account to another, from some server side config instead of configuring email clients for rules. I have tried Google Apps Mail but it doesn't allow auto cc of outgoing emails. After having read tons of blogs, forum messages etc (hope I have been reading the correct info :) ) the only option to achieve what I am needing is to setup my own mail server, but the cost of getting a static IP doesn't fit my budget. Please can someone point me in the correct direction. Platform doesn't matter, I can setup a Windows or Linux server. Many Thanks

  • Chassis fans and power LEDs still work in Hibernate

    - by Jaded
    I have ASRock Z68 Extreme3 Gen3 motherboard recently updated to 2.20 BIOS version. OS is Windows 7 x64. The problem is after that update full hibernation (by that i mean full system power off) stopped working although everything was fine before. Now when I press hibernate, sleep in initiated as usual, monitor goes to sleep, HDD and CPU fan stop spinning, but chassis fans (i have Gigabyte Aurora 3D 570 case with two rear and one front fans) still remain working. Also power leds are lit as if computer is turned on. Tried changing different UEFI settings related to sleep mode, and none of them change above described behaviour. I have "Deep Sleep" (Advanced-South Bridge Configuration) set to "Enabled in S4-S5", "Suspend to RAM" (Advanced-ACPI Configuration) set to "Auto", all fans settings in "H/W Monitor" set to "Auto".

  • How to get an inactive RAID device working again?

    - by Jonik
    After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

  • Name typing in the "TO" line for last name recognition

    - by Buck
    I have outlook 2010 on a Windows 7 laptop. When I go to send an email at the "TO" line and I start typing the name, if I start to enter the last name it will not recognize anyone in my contacts and will not auto-populate a list of all the names that fit the description of what I have typed so far. But if I start typing the first name first it will start this auto-choice feature based on what I have typed so far. The company I work for has 20k + employees and If I want to email someone like "Michael Hutch " if I type "Michael" it still gives me like 800 names to chose from. My old laptop that had 2003 Outlook on it, had this functionality. Is there a way to enable this in Outlook 2010?

  • Getting kernel errors when manually mounting VirtualBox shared folders

    - by Ross
    Updated: I've rephrased this problem as I understand it a bit more now (and have encountered another problem). I'm using a Fedora 15 guest on a Windows 7 host using VirtualBox. I am trying to mount a partition on the host PC as a shared folder for use in the guest. The folder appears in /media and is accessible when I use the auto-mount feature when setting up the shared folder, but when I attempt to mount without auto-mount I get the following error: $ sudo mount.vboxsf data /mnt/host_data /sbin/mount.vboxsf: Could not add an entry to the mount table.: Invalid argument In addition a popup appears (part of Fedora/GNOME) reporting a crash in the kernel package: WARNING: at lib/list_debug.c:26 __list_add+0x3e/0x81() However the shared folder seems to work, I can certainly browse it (although everything seems to be executable, probably down to a Windows host). Is there something wrong with what I'm doing or is this a bug (and in which case should it be reported to the Linux Kernel team or VirtualBox)?

I have installed the SquirrelMail plugin and the Auto respond option is available for the users, but when an email is sent to the addresses no auto reply email is sent to the sender. There are also no logs on the /var/log/vacation folder which i created as well as the normal log files. Most of the examples online refer to virtual users, can it work with local users? and if so how? regards, Arthur
