  • Rebuilding LVM after RAID recovery

    - by Xiong Chiamiov
    I have 4 disks RAID-5ed to create md0, and another 4 disks RAID-5ed to create md1. These are then combined via LVM to create one partition. There was a power outage while I was gone, and when I got back, it looked like one of the disks in md1 was out of sync - mdadm kept claiming that it only could find 3 of the 4 drives. The only thing I could do to get anything to happen was to use mdadm --create on those four disks, then let it rebuild the array. This seemed like a bad idea to me, but none of the stuff I had was critical (although it'd take a while to get it all back), and a thread somewhere claimed that this would fix things. If this trashed all of my data, then I suppose you can stop reading and just tell me that. After waiting four hours for the array to rebuild, md1 looked fine (I guess), but the lvm was complaining about not being able to find a device with the correct UUID, presumably because md1 changed UUIDs. I used the pvcreate and vgcfgrestore commands as documented here. Attempting to run an lvchange -a y on it, however, gives me a resume ioctl failed message. Is there any hope for me to recover my data, or have I completely mucked it up?

  • Execute encrypted files but don't let anybody read them.

    - by Stebi
    I want to provide a virtual machine image with an installed web application. The user should be able to boot the vm (don't login, just boot) and a webserver should start automatically. The point is I want to hide the (ruby) source code of the web application from everyone as there is no obfuscator for ruby. I thought I could use file system encryption to encrypt the directory with the sourcecode (or even a whole partition). But the webserver user must be able to read it automatically after booting. Nobody is allowed to login as the webserver user (or any other user) so no other can read the contents. My questions are now: Is this possible? Because I give away the whole vm everybody could mount its virtual discs and read them (except the encrypted one). Is it now possible to find the key the webserver user needs to decrypt the files and decrypt them manually? Or is it safe to give such a vm away? The problem is that everything needed to decrypt must be included somewhere in the vm else the webserver cannot start automatically. Maybe I'm completely wrong and you have another tip for me securing the source code.

  • SSH connection falling down

    I've set up a connection with autossh that creates some tunnels at system startup, but if I try to connect, after successful login (with RSA key) connection fall down, here a trace: debug1: Authentication succeeded (publickey). debug1: Remote connections from LOCALHOST:5006 forwarded to local address localhost:22 debug1: Remote connections from LOCALHOST:6006 forwarded to local address localhost:80 debug1: channel 0: new [client-session] debug1: Requesting [email protected] debug1: Entering interactive session. debug1: remote forward success for: listen 5006, connect localhost:22 debug1: remote forward success for: listen 6006, connect localhost:80 debug1: All remote forwarding requests processed debug1: Sending environment. debug1: Sending env LANG = it_IT.UTF-8 debug1: Sending env LC_CTYPE = en_US.UTF-8 debug1: client_input_channel_req: channel 0 rtype exit-status reply 0 debug1: client_input_channel_req: channel 0 rtype [email protected] reply 0 debug1: channel 0: free: client-session, nchannels 1 Transferred: sent 2400, received 2312 bytes, in 1.3 seconds Bytes per second: sent 1904.2, received 1834.4 debug1: Exit status 1 What can be the problem?

  • How to Configure Sendmail / Webmin for second IP?

    - by user310594
    Hi, LAMP Centos5.4 Webmin Until recently I have had all domains using "server1.example.com" Now I have newdomain.com on second.ip.address.works (works for DNS that is) Please tell me how to setup sendmail so the mail is sent from the second ip address? This is new for me: IF I need to create a second server called "server2.domain2.com", then please tell exactly how since I'm only experienced with one server per VPS. Whether "server2.domain2.com" needs to be created or not, here is exactly what is needed: # Mail being sent from domains using ns1.example.com needs to be sent from that server and that IP. Mail being sent from domains using nsother.example2.com sent from that IP + how to set up the second server / hostname, if needed. Thank you.

  • Anyone know a good web-based file upload package?

    - by Ted Wexler
    Basically, what I'm looking for is a place for either one of our end users to be able to upload a file to this package, after either receiving a code from one of our support engineers or vice-versa(our engineers upload a file and send a code/link/something to end user) I've spent a bunch of time googling this, I found this: http://turin.nss.udel.edu/programming/dropbox2/, but the code there scares me, and it also doesn't render properly using PHP 5.3(uses short tags, who knows what else.) Does anyone have any recommendations?

  • Not able to connect to internet in RHEL 5

    - by chankey007
    I just installed red hat enterprise 5 in my laptop and on desktop both. In desktop it is working fine but in laptop it is not showing the eth device. (I tried ifconfig only lo is there). I tried ifup eth0 still nothing happened. The network service in /etc/sysconfig/network-scripts/ifcfg-eth0 and in /etc/sysconfig/network are enable. I had ubuntu in my laptop before and I faced same problem with that too. Is there any problem with my laptop? I have my system on dual boot and in win7 networking is running fine. I am not able to connect to the internet only, other devices are working fine. System conf: Sony vaio E series. 3 GB RAM, intel core i3 2.13 GHZ.

  • How can I avoid SSH's host verification for known hosts?

    - by shantanuo
    I get the following prompt everytime I try to connect a server using SSH. I type "yes", but is there a way to aovid this? The authenticity of host '111.222.333.444 (111.222.333.444)' can't be established. RSA key fingerprint is f3:cf:58:ae:71:0b:c8:04:6f:34:a3:b2:e4:1e:0c:8b. Are you sure you want to continue connecting (yes/no)?

  • One NIC going to sleep on Centos system

    - by sbleon
    I have two Dell boxes with two ethernet ports a piece. I have a cable directly connecting two of these ports, creating a tiny LAN with 10.3.3.x addresses. The other port on each box is hooked up to a switch and has a DHCP-supplied address to talk to the outside world. I've noticed that when scp'ing large files from one box to the other over the private LAN, the transfers sometimes stall. It appears that any other network activity on either box will cause the transfer to resume. Wake-on-LAN is disabled on all interfaces according to ethtool. What else could be causing these stalled transfers?

  • mount multiple folders with nfs4 on centos

    - by microchasm
    I'm trying to get nfs4 working here. Machine 1 (server) I have a folder and in it 2 other folders I'm trying to share independently. /shared/folder1 /shared/folder2 Problem is, I can't seem to figure out how to mount the folders independently on the client. (Machine 1 - server) /etc/exports: /var/shared/folder1 192.168.200.101(rw,fsid=0,sync) /var/shared/folder2 192.168.200.101(rw,fsid=0,sync) ... exportfs -ra (Machine 2 - client) /etc/fstab: 192.168.200.201:/folder1/ /home/nfsmnt/folder1 nfs4 rw 0 0 ... mount /home/nfsmnt/folder1 mount.nfs4: 192.168.200.201:/folder1/ failed, reason given by server: No such file or directory The folder is there. I'm positive. I think there is something simple I'm missing, but I'm totally missing it. It seems like there should be a way in fstab to tell nfs which folder on the server I want to mount. But I can only find references to what looks like a root mount point (e.g. 192.168.1.1:/) which I assume is handled by exports on the server. But even with the folders set up in exports, there doesn't seem to be an apparent way to pich and choose which gets mounted. Is it not possible to mount separate folders from the same server to different mount points on the client? Any help appreciated.

  • Ubuntu 11.10 firewall/gateway - no client internet access

    - by Siriss
    I have read many other posts but cannot figure this out. eth0 is my external connected to a Comcast modem.

  • Mount "Macrium Reflect" on a partition, boot from there?

    - by b e
    Can Macrium's Reflect recovery CD be mounted/used with GRUB ? If the cd can be 'put' (loaded/mounted/...) in a partition, then the only disc needed would be the actual recovery disc, which could be on an external hard drive, or even on the same machine in another partition, thus allowing on to recover using only what's on the machine itself. I have WXPpro and Xubuntu8.04 double mounted, really happy with them together, use each right now to fix problems with the other when they come up. Also have a partition for the Reflect CD, but I just can't get it to load from Grub, which would be great... Thanks for any thoughts, probably someone has already done this I know !

  • Server not responding to SSH and HTTP but ping works

  • 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:

  • Change permission to /proc/net/ip_conntrack on Ubuntu server 9.10

    - by bjarkef
    Hi I have a script that needs to extract certain information form the /proc/net/ip_conntrack file once in a while. I do not wish to run this script as the root user. Default permissions for the file is: $ ls -lah /proc/net/ip_conntrack -r--r----- 1 root root 0 2010-03-28 12:18 /proc/net/ip_conntrack I can change it with: sudo chmod o+r /proc/net/ip_conntrack But that does not stick after a reboot. Is there some configuration file for file-permissions in the /proc directory in Ubuntu Server 9.10? Or do I just have to stick a chmod line in some startup script?

  • Different graphic cards drivers while booting from external media

    - by goran
    I am booting a certain system of mine with ubuntu 9.10 from external HDD. I am satisfied with the setup and it works fine, however I would like to modify it so that I can choose which graphic card drivers to load during the boot time. Specifically I would like to choose between: nvidia proprietary driver ati proprietary driver generic driver Currently if I am using proprietary drivers then dont boot into X, delete xorg.conf, start gdm and reconfigure the system using jockey (for hardware drivers). What would be the steps to make this (semi-)automatic and avoid restarting X?

  • Disable ipv6 support completely on debian squeeze 6.0.5

    I want to disable ipv6 support completely on debian squeeze 6.0.5. In many other posts I have seen setting the parameter net.ipv6.conf.all.disable_ipv6 = 1 in /etc/sysctl.conf should disable it.

  • Set custom mount point and mount options for USB stick

    - by kayahr
    Hello, I have an USB stick which contains private stuff like the SSH key. I want to mount this stick to my own home directory with 0700 permissions. Currently I do this with this line in /etc/fstab: LABEL=KAYSTICK /home/k/.kaystick auto rw,user,noauto,umask=077,fmask=177 0 0 This works great but there is one minor problem: In Nautilus (The Gnome file manager) the mount point ".kaystick" is displayed. I guess Nautilus simply scans the /etc/fstab file and displays everything it finds there. This mount point is pretty useless because it can't be clicked when the device is not present and it can't be clicked when the device is present (Because then it is already mounted). I know this is a really minor problem because I could simply ignore it but I'm a perfectionist and so I want to get rid of this useless mount point in Nautilus. Is there another way to customize the mount point and mount options for a specific USB device? Maybe it can be configured in udev? If yes, how?
