• Software Raid 10 on VirtualBox?

  - by user791022

  I want to learn how to use Software Raid 10, is it possible to use VirtualBox by adding four storage images? This is my plan: 4x 100mb partitions (1 on each drive) configured as a raid 1 for /boot in ext3. Then with the remaining space on each drive, setup a software raid partition and configure it to to LVM and raid 10. In the LVM, set up a 4gb swap partition and the remaining space as the root partition ( / ) as ext3.

• Successful su for user by root in /var/log/auth.log

  - by grs

  I have this sorts of entries in my /var/log/auth.log: Apr 3 12:32:23 machine_name su[1521]: Successful su for user1 by root Apr 3 12:32:23 machine_name su[1654]: Successful su for user2 by root Apr 3 12:32:24 machine_name su[1772]: Successful su for user3 by root Situation: All users are real accounts in /etc/passwd; None of the users has its own crontab; All of those users are logged in the machine some time ago via SSH or No Machine - time varies from few minutes to few hours; no cron jobs are scheduled to run at that time, anacron is removed; I can see similar entries for other days and other times. The common part is the users are logged in when it appears. It does not appear during login, but some time afterwards. This machine has similar setup with few others but it is the only one where I see these entries. What causes them? Thanks

• My smtp server is spammed?

  - by Milos

  I have a server and the postfix client on it. Since several days, I noticed a lot of processes running there. When checked, there are a lot of emails sent.

• How can I recover an ext4 filesystem corrupted after a fsck?

  - by Regan

  I have an ext4 filesystem on luks over software raid5. The filesystem was operating "just fine" for several years when I was beginning to run out of space. I had a 9T volume on 6x2T drives. I began upgrading to 3T drives by doing the mdadm fail, remove, add, rebuild, repeat process until I had a larger array. I then grew the luks container, and then when I unmounted and tried to resize2fs I was given the message the filesystem was dirty and needed e2fsck. Without thinking I just did e2fsck -y /dev/mapper/candybox and it began spewing all kinds of inode being removed type messages (can't remember exactly) I killed e2fsck and tried to remount the filesystem to backup data I was concerned about. When trying to mount at this point I get: # mount /dev/mapper/candybox /candybox mount: wrong fs type, bad option, bad superblock on /dev/mapper/candybox, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Looking back at my older logs I noticed the filesystem was giving this error each time the machine booted: kernel: [79137.275531] EXT4-fs (dm-2): warning: mounting fs with errors, running e2fsck is recommended So shame on me for not paying attention :( I then tried to mount using every backup superblock (one after another) and each attempt left this in my log: EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 0 failed (26534!=65440) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 1 failed (38021!=36729) EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 2 failed (18336!=39845) ... EXT4-fs (dm-2): ext4_check_descriptors: Checksum for group 11911 failed (28743!=44098) BUG: soft lockup - CPU#0 stuck for 23s! [mount:2939] Attempts to restart e2fsck results in: # e2fsck /dev/mapper/candybox e2fsck 1.41.14 (22-Dec-2010) e2fsck: Group descriptors look bad... trying backup blocks... candy: recovering journal e2fsck: unable to set superblock flags on candy At this point, I decided it best to order some more drives and make an image using ddrescue Now two weeks later I have an image of the luks partition in a .img file. # ls -lh total 14T -rw-r--r-- 1 root root 14T Oct 25 01:57 candybox.img -rw-r--r-- 1 root root 271 Oct 20 14:32 candybox.logfile After numerous attempts using everything I could find online I could not coerce e2fsck to do anything on the image, so I used mkfs.ext4 -L candy candybox.img -m 0 -S and I was able to mount the dirty filesystem readonly without the journal and recover 960G of data. It gave all kinds of errors of various directories not existing and so forth but I was able to get some stuff. Which gave me some hope! I then ran e2fsck again and it had to recreate the root inode and gave a massive list of correcting group counts, I accepted the root inode creation and said no to everything else, leaving a completely empty filesystem. Re-ran again and said yes to all questions with the same result but now a "clean" but empty filesystem. extundelete gives me 0 recoverable inodes found. And now I'm stuck again, I can't come up with any other methods other than dropping to something like photorec which will give me an absolute mess with how large the filesystem was. I'm willing to re-copy the image from the original array and start over, if I can get any suggestions or ideas on a way to get more of my files back. I wish I could give more detailed logs of the commands that have run, but the output is long scrolled passed except for what gets logged to syslog and my memory is not as detailed due to the timeframe this has occurred over. Any help is greatly appreciated!

• How to migrate KVM based VMs running in LVM setup to Vmdk images

  - by Bond

  I am using KVM on Ubuntu Server 10.04. and Virtual Machines are running on it in LVM. I have to migrate some of them to Vmware server.How can I achieve this? I searched and came across some links but they all talked converting vmdk images to qcow or so.In this case I have OS in LVM. I also looked at man page of qemu-img and as I understand it should do what I am asking in this thread. But how exactly should I proceed in this case.Since it is not a file based image (OS running in an LVM which has filesystem in that LVM). So I am not able to understand what should I be doing to achieve the same. Can I achieve the above with snapshots of LVMs rather than shutting down the VM itself.

• How to exit vncconfig process properly

  - by Stan

  On CentOS 5.7, when open up a vncconfig, a tray icon shows on the taskbar. Hit close or the x button to close the vncconfig doesn't exit the vncconfig, the tray icon is still there. Next time, if I open up another vncconfig rather than clicking the one on taskbar. There will be another vncconfig tray icon added to the taskbar. Except using kill $pid to remove the tray icon, is there any other way to exit the vncconfig process properly? See screenshot below:

• Web Server Users - Best Practice

  - by Toby

  I was wondering what is considered best practice when several developers/administrators require access to the same web server. Should there be one non-root user with a secure username and password unqiue to the web server which everyone logs in as or should there be a username for each person. I am leaning towards a username for each person to aid in logging etc however then does the same user keep the same credentials over several servers, or should at least their password change depending on the server they are on? Should any non-root user of the system be added to the sudoers file or is it best practice to leave everyone off it and only let root perform certain tasks? Any help would be greatly appreciated.

• Route return traffic to correct gateway depending on service

  - by Marnix van Valen

  On my office network I have two internet connections and one CentOS server running a website (HTTPS on port 443). The website should be publicly accessible through the public IP of the first internet connection (ISP-1). The other internet connection, ISP-2, id the default gateway on the network. Both internet connections have routers (the household-kind) with NAT, SPI firewalls etc. The router on ISP-2 is a Netgear WNDR3700 (aka N600) with original firmware. The problem is that the website is unreachable. Looks like incoming traffic on ISP-1 will reach the server but the returning traffic is routed through ISP-2, effectively making the site unreachable. As far as I can tell I can't do port based routing on the WNDR3700. What are my options to make this work? I've been looking at implementing an iptables / routing based solution on the server itself but haven't been able to make that work. Update: Note that the server has one network interface connecting it to both routers.

• Change/Deactivate the shell for an amount of users on SUSE Enterprise Server

  - by Manfred Schmidt

  I have a SUSE Server to which ~300 users are connecting. About 100 of them have to be deactivated. I think it would be nice to change their shell to /bin/false either with chsh or with usermod. Do I have to type every command per line, or can I fill out a list of users which can be read from the script? I should mention that all of the 100 users have the same ending in their username. Can I work with wildcards here? e.g. usermod -s /bin/fish *ftpuser chsh -s /sbin/nologin *ftpuser

• Advantages of a deployment tool over shell

  - by Jimmy

  Currently I have all of my deployment scripts in shell, which installs about 10 programs and configures them. The way I see it shell is a fantastic tool for this: Modular: Only one program per script, this way I can spread the programs across different servers Simple: Shell scripts are extremely simple and don't need any other software installed One-click: I only have to run the shell script once and everything is setup Agnostic: Most programmers can figure out shell, and don't need to know how to use a specific program. Versioning: Since my code is on github a simple git pull and restart all of supervisor will run my latest code. My question is, with all of these advantages, why is it people are constantly telling me to use a tool such as ansible or chef, and not to use shell.

• crontab: question about a special case of the dash character in the time field spec

  - by mdpc

  In the SuSE /etc/crontab the entry to run the cron.{hourly,daily,monthly,weekly} scripts is coded as: -*/15 * * * * root test -x /usr/lib/cron/run-crons && /usr/lib/cron/run-crons /dev/null 2&1 Notice that the very first character of the specification is a dash character (-), and this is NOT a typo. Can somebody explain what the time spec '-*/15' means? BTW, the stuff seems to be running fine. Thanks

• "Can't find root filesystem / error mounting /dev/root" when booting to new kernel

  - by salparadise

  I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers. When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common_kernel_problems#Can.27t_find_root_filesystem_.2F_error_mounting_.2Fdev.2Froot From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel. Doing a diff from the old initrd to the new one gives me the following: root-> diff /tmp/kafter /tmp/kbefore 6a7,8 > lib/dm-message.ko > lib/dm-region_hash.ko 8a11 > lib/dm-raid45.ko 13d15 < lib/dm-region-hash.ko 16a19 > lib/dm-mem-cache.ko Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid.

• How can I turn off font-antialiasing only for gnome-terminal, but not for other applications?

  - by dan

  I'm running GNOME (gnome-session under xmonad). I want to turn off antialiasing (i.e. use monochrome mode) for fonts in gnome-terminal. But I want to retain antialiasing for other applications, like Firefox. Is this possible? Antialiasing is great and almost necessary for using Firefox or Chrome. But it makes the fonts in gnome-terminal blurry at sizes around 12 or smaller. Otherwise, I'll just have to use xterm, which seems not to anti-alias its fonts under any circumstances.

• Ubuntu hardware wireless switch has no effect after suspend and 13.10 upgrade

  - by blaineh

  I'm posting this on SU after it stalled on askubuntu. I hope someone here can help! If you'd prefer to answer on AU itself, here's the link: http://askubuntu.com/questions/365177/hardware-wireless-switch-has-no-effect-after-suspend-and-13-10-upgrade Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Edit. This morning, I had had the laptop suspended all night, and then when I tried to awake it, it simply wouldn't. It would try, and then it would sleep again (I guess it felt a little bit like me! </badjoke>). Is it possible these problems are related? Edit. I don't have enough reputation on SU proper to post links to pastebins and other questions I've tried, so I'm putting them in comments, and of course they're available in the original question.

• Changed array composition, mdadm --detail still shows the old array size

  - by Prody

  I have a machine with 8 disks. I installed it with my hoster's install automation (it's OVH, I don't have physical access to it). The machine installed correctly, but it made an array that I wanted to change. It created a raid5 array across 5/8 disks and I've changed it to raid10 across 8 disks. I've done this by first --stopping the old array and then --creating the new array. It warned me that a previous array was there, but I chose to continue. So it created the array, spent 10ish hours syncing it and now that it's ready I get this strange behavior: When I fdisk p on it, I see the correct size. But when I mdadm --detail it I see the old array's size even tho I get the new composition and level. When I try to pvcreate on it, i get the old size again for some reason. Did I have to do something else? Did I miss something?

• Hardware needed for receiving and recording videocalls in Asterisk

But it's not clear to me what are the hardware requirements for this. Can someone enlighten me?

• Streaming audio/video in a publicly-hosted server increases bandwith usage

  - by Eka

  I have a website hosted in a public server (withoud any streaming content) ,using public hosting instead of private because its cheaper. But in public hosting their are limitations when compared to private hosting such as monthly bandwidth usage (1 GB), disk space, cpu usage etc. I am planning to embedd videos and audios (from other websites like youtube) to my already existing website. My question is if a client streams a embedded video/audio (hosted in another website) from my website any change in bandwidth occurs.

• Primary/secondary ethernet interfaces via NetworkManager in Ubuntu 9.10

  - by Josh

  I have an Ubuntu 9.10 machine with three ethernet interfaces, eth0, eth1 and eth2. eth2 is connected to a private network. eth0 and eth2 are connected to two different LANs. Either one will provide access to the internet. All three networks have DHCP servers. Using Ubuntu's the default settings (And Gnome), when I boot up all the interfaces are active and my system gets three IP addresses. However any attempt to access the internet results in connection timeouts and other weirdness. I suspect that traffic is going out on one NIC (like eth0) and coming back in on another (like eth1). I'm not sure what's going on. The only way I can access the internet at the moment is to bring two of the devices down with ifdown. How can I configure eth0 as my primary interface so all trafic goes out by default on that interface, while keeping the other two active? Also, I want to make sure Avahi broadcasts properly on all three IPs so that the computers on the LAN of eth1 can still connect to myHostname.local... EDIT: Here's my routing table: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.151.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 172.16.30.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.1.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 172.16.30.2 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 10.1.0.1 0.0.0.0 UG 0 0 0 eth1 I want the 172.16.30.2 network to be the primary one and the 10.1.0.0 network to be the secondary one.

It seems like Ubuntu is bringing the networks up in order, eth0, then 1, then 2, and the DHCP information from eth1 is overriding eth0, and eth2 is overriding eth1. How can I reverse this so the DHCP information from eth0 is the "master"? EDIT3: This seems to be an issue with Gnome's NetworkManager.

• How can I run a job when the server load is low?

  - by jberryman

  I have a command that runs a disk snapshot (on EC2, freezing an XFS disk and running an EBS snapshot command), which is set to run on a regular schedule as a cron job. Ideally I would like to be able to have the command delayed for a period of time if the disk is being used heavily at the moment the task is scheduled to run. I'm afraid that using nice/ionice might not have the proper effect, as I would like the script to run with high priority while it is running (i.e. wait for a good time, then finish fast). Thanks.

• mount qcow2 snapshots

  - by phhe

  I'm running some Xen-servers and started migrating to KVM. Currently my guests are either running on raw-images or LVMs. I found libvirt providing some very nice snapshot features (virsh snapshot-create, ...) so I decided to use qcow2 instead of raw/lvm. And here is my question: libvirt creates the same sort of snapshots on the qcow2 image as if I use qemu-img - is it possible to mount them ? I read something about qemu-nbd and the possibility of mounting qcow but I could not find a word about snapshots.

• Ubuntu server loses network connection after ADSL2+ modem reset

  - by squashbuff

  I am using an ubuntu 10.04 server (running on a Lenovo Thinkpad notebook) as my webserver. It is performing well in terms of handling the traffic etc. However my internet connection is ADSL2+ (using Thomson TG782T modem-router) and if the modem is reset, then my server loses network connection. The networkmanager icon shows a red exclamation mark showing that is has no connection. But as soon as I click on it and tell it to connect to eth0, the connection is back on. It must be something that networkmanager is failing to do and because of this, the reliability of my webserver is suffering. Any advice on how this can be fixed?

• How can I copy the output from a remote command into the local clipboard?

  - by cwd

  I use iTerm2 as my terminal client in Mac OS X. On the local system I can use pbcopy and pbpaste to transfer data between the system clipboard and the terminal, but of course this doesn't work when you're ssh'ed to another machine. Is there some way which I can take the result of a command and copy it to the clipboard automatically? Perhaps an applescript to grab the text on the iTerm windows, then get the next to last line? For instance, if I wanted to copy the current working directory: I run pwd, then use the mouse to select the text, and then press command + c. Is there any better / faster / automatic way of doing this? I'm not looking for a bulletproof solution that would work for every command (eg: might not work when there is a huge scrollback) - I'm just looking for something to make this task that I do quite often a little less tedious. Update I'm looking into using screen to do this, but I'm still not sure if it is possible.
