• How to restore a dd overwritten disk partition?

  - by DairyKnight

  First of all, I admit I'm stupid and I didn't run proper backup of my data, but you know crap happens... So, I've used dd to overwrite the first 2GB of my 750GB NTFS partition with a FAT32 partition. I've run Photorec and EasyRecovery but all I can restore is the 2GB FAT32 partition and the files on that. Is there a way to "roll back" to the NTFS paritition, and recover - at least - some part of the 750GB data? Thanks.

• Bad I/O scheduler?

  - by user62367

  os: up-to-date Fedora 14. Working as a "normal desktop". It's doing very well, but if i start VirtualBox, and e.g.: install a guest on it, it just "freezez". I mean if there are disk activities on a VirtualBox guest, then the computer becomes unrespondable..even the mouse is laggin for about 50 minutes.. What could be the bottleneck? What could be the problem? If anyone has any tips/howtos to speed it up, please help! It has a normal 2,5" HDD, with 5400 RPM. Does it worth for me if i buy a 2,5" HDD with 7200 RPM? T7200 cpu, 4 GByte RAM, "vm.swappiness = 0". Thank you!

• Machine check events logged

  - by GoldenNewby

  In /var/log/messages, this error occurred: Sep 19 13:18:15 wdc kernel: [2772302.630416] Machine check events logged Shortly there after, the entire server became unresponsive. This is in the log of the Dom0 for a Xen Server (running the latest version on Debian Squeeze). Can anyone shed some light on what this error means? Should I be ordering new hardware? Edit: Also, it seems to imply it logged something, where can I find that?

• Bash Script Exits su or ssh Session Rather than Script

  - by Russ

  I am using CentOS 5.4. I created a bash script that does some checking before running any commands. If the check fails, it will simply exit 0. The problem I am having is that on our server, the script will exit the su or ssh session when the exit 0 is called. #!/bin/bash # check if directory has contents and exit if none if [ -z "`ls /ebs_raid/import/*.txt 2>/dev/null`" ]; then echo "ok" exit 0 fi here is the output: [root@ip-10-251-86-31 ebs_raid]# . test.sh ok [russ@ip-10-251-86-31 ebs_raid]$ as you can see, I was removed from my sudo session, if I wasn't in the sudo session, it would have logged me out of my ssh session. I am not sure what I am doing wrong here or where to start.

• RHEL 5/CentOS 5 - sshd becomes unresponsive

  - by ewwhite

  I have a number of CentOS 5.x and RHEL 5.x systems whose SSH daemons become unresponsive, preventing remote logins. The typical error from the connecting side is: $ ssh db1 db1 : ssh_exchange_identification: Connection closed by remote host Examining /var/log/messages after a forced reboot shows the following leading up to the restart: Dec 10 10:45:51 db1 sshd[14593]: fatal: Privilege separation user sshd does not exist Dec 10 10:46:02 db1 sshd[14595]: fatal: Privilege separation user sshd does not exist Dec 10 10:46:54 db1 sshd[14711]: fatal: Privilege separation user sshd does not exist Dec 10 10:47:38 db1 sshd[14730]: fatal: Privilege separation user sshd does not exist These systems use LDAP authentication and the nsswitch.conf file is configured to look at local "files" first.

• Clients didn't switch to secondary DNS server during fail over

  - by The Digital Ninja

  I have two internal dns servers set up and all my servers have both of them in the resolv.conf Our main dns server went down and suddenly no server could see each other. I edited a few of the servers resolv.conf manually and committed out the first (down) dns server and that machine would instantly be able to ping again. What did I do wrong, does it not auto switch to the secondary dns server when it times out? # File managed by puppet nameserver 192.168.146.100 nameserver 192.168.159.101 ;nameserver 72.14.188.5 domain example.com search example.com

• RHEL 5.3 Kickstart - How specify location of individual package in Workstation folder?

  - by Ed

  I keep getting "package does not exist" errors during the install. I made a kickstart ISO to create an unattended install of a RHEL 5.3 build machine for C++ software releases. It pulls the kickstart config file from our internal web server. This is handy; it makes it easy to test and modify without having to make a new ISO. And I plan to check it in to version control if I can get it working. Anyway, the rpm packages are located in two folders on the disk; Client and Workstation. The packages install fine for the ones that are physically located under the Client folder. It cannot find those under the Workstation folder such as as doxygen and subversion complaining that packages do not exist. Is there a way to specify the individual package location? # ----------------------------------------------------------------------------- # P A C K A G E S # ----------------------------------------------------------------------------- %packages @gnome-desktop @core @base @base-x @printing @development-tools emacs kexec-tools fipscheck xorg-x11-server-Xnest xorg-x11-server-Xvfb #Packages Located in Workstation Folder *** Install can not find any of these ?? bison doxygen gcc-c++ subversion zlib-devel freetype-devel libxml2-devel Thanks in advance, -Ed

• Monitoring outgoing bandwidth of application

  - by jnolte

  I currently have a VPS that is consuming a ton of outgoing bandwidth and I am trying to drill down to where this may be coming from. Does anyone know of a logical way to go about finding out which pages on the site are consuming the most outgoing data. We have done a ton of front-end optimizations to the site and our google page speed rankings ar 85% so I feel we have done a pretty great job at optimizing the site for speed. Can someone lend some insight on how they have made similar optimizations? Application / Server Stack LEMP Running Varnish Cache / PHP5-FPM WordPress running w3 Total Cache Ubuntu 12.04 LTS

• How to improve the HTML formatting in Evolution mail client

  - by Tom

  I have a question about viewing HTML emails in the Evolution mail client. Basically, I am receiving some emails that look lovely in Thunderbird but not in Evolution because the HTML rendering of Evolution isn't as advanced. Does anyone know how to improve the HTML rendering of Evolution? e.g. a plugin, tip, code patch, etc... The closest I've got is to right-click the email, "Save As...", save as a html file, then open in Firefox. Not exactly streamline! What emails can't it display well? We use the subversion revision control system which is set up to send an email whenever someone commits via svnnotify all nicely coloured via the --handler HTML::ColorDiff -d parameter. When Evolution fails to use the colours, I find it very had to read the raw diff.

• open mysql to any connection on ubuntu

  - by ThomasReggi

  I simply want to open up mysql to be accessible from any server ip. I have already commented out the bind-address in /etc/mysql/my.conf. I have already setup the user account within mysql. I have no clue whats stopping me from connecting. The more challenging I see this being the more I realize how much of a security risk it is, and I get that, I just want to be able to do it temporarily. I think that the iptables firewall is the last thing that is preventing me from achieving this, but sudo iptables -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT is seemingly doing nothing.

• Good Free Ubuntu Server VMWare Image Needed

  - by Yaakov Ellis

  Can anyone recommend a good, free Ubuntu Server VMWare Image (or Virtual Appliance, as they call them)? I have looked on the VMWare VAM and there are literally hundreds to choose from. I am looking for something that can with very minimal effort serve as a development platform for LAMP applications (so it should have all of those installed, plus things like PhpMyAdmin). Bonus points if there is some way to create new Virtual Hosts (for developing and testing new sites) on Apache without having to go digging around conf files and guessing on the sytax.

• IPv6 static routes

  - by user98651

  I am looking to configure a few hosts with IPv6 on my network. The router (running CentOS 5) is configured with an Hurricane Electric (HE) tunnel which works fine on that host. However, I would like to statically add a few additional hosts on the same LAN to have IPv6 through this tunnel. No, I don't want radvd or dhcpv6 to do the work for me in this case. I already have IPv6 forwarding enabled in sysctl.conf. I am looking for help with the next steps (statically adding the routes). Lets say the IP addresses are as follows: Router: 2001:470:1b07:1:: Host1: 2001:470:1b07:2:: How would I go about making them see each other? Thanks in advance for the help.

• Squid Authentication & streaming

  - by Steve Butler

  I've got squid setup using Kerberos authentication. I'm also using squidguard as an URL redirector to block out the usual nastiness of the web. There are some sites though that we allow certain users to, and others not. This all works well, assuming I'm not using any streaming. From what i can determine from the squid logs and the wireshark traces I've done, when the initial request to stream is sent, everything is good, the authenticated username is sent with the request to squidguard. The problem is that on subsequent traffic the username is not sent to squidguard, causing it to be blocked based on default policy. I've tried using the squid built-in allow/deny stuff, but its relatively clunky, and so far squidguard has been pretty easy and fast. Here comes the question(s): How do i get Squid to pass username on all requests? (something tells me this isn't the best way) How do i get squidguard to see traffic is authenticated to a specific user even when a username isn't passed? Is there any other way of accomplishing this? A few details that may be of importance: I'm using a list of users stored in a text file for squidguard to compare against. I'm using full kerberos auth with Squid. CentOS 6.0 Squid 3.1.4 Squidguard 1.3

• Keeping new Ubuntu installation's /var on separate drive without formatting

  - by tlayton

  I have a server running an older version of Ubuntu and with /var stored on a separate partition on a separate hard drive. I am attempting to update Ubuntu to 10.04, but I still want to store /var on a separate partition and hard drive. However, I don't want to format the drive which currently contains /var, as it has important data. Is there some way to have 10.04 set up the new /var on this separate drive at installation, without formatting the drive and losing the old /var?

• Stop squid caching 302 and 307 with deny_info

  - by 0xception

  TLDR: 302, 307 and Error pages are being cached. Need to force a refresh of the content. Long version: I've setup a very minimal squid instance running on a gateway which shouldn't not cache ANYTHING but needs to be solely used as a domain based web filter. I'm using another application which redirects un-authenticated users to the proxy which then uses the deny_info option redirects any non-whitelisted request to the login page. After the user has authenticated the firewall rule gets placed so they no longer get sent to the proxy. The problem is that when a user hits a website (xkcd.com) they are unauthenticated so they get redirected via the firewall: iptables -A unknown-user -t nat -p tcp --dport 80 -j REDIRECT --to-port 39135 to the proxy at this point squid redirects the user to the login page using a 302 (i've also tried 307, and i've also make sure the headers are set to no-cache and/or no-store for Cache-Control and Pragma). Then when the user logs into the system they get firewall rule which no longer directs them to the squid proxy. But if they go to xkcd.com again they will have the original redirection page cached and will once again get the login page. Any idea how to force these redirects to NOT be cached by the browser? Perhaps this is a problem w/ the browsers and not squid, but not sure how to get around it. Full squid config below. # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 192.168.182.0/23 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl https port 443 acl http port 80 acl CONNECT method CONNECT # # Disable Cache # cache deny all via off negative_ttl 0 seconds refresh_all_ims on #error_default_language en # Allow manager access only from localhost http_access allow manager localhost http_access deny manager # Deny access to anything other then http http_access deny !http # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !https visible_hostname gate.ovatn.net # Disable memory pooling memory_pools off # Never use neigh cache objects for cgi-bin scripts hierarchy_stoplist cgi-bin ? # # URL rewrite Test Settings # #acl whitelist dstdomain "/etc/squid/domains-pre.lst" #url_rewrite_program /usr/lib/squid/redirector #url_rewrite_access allow !whitelist #url_rewrite_children 5 startup=0 idle=1 concurrency=0 #http_access allow all # # Deny Info Error Test # acl whitelist dstdomain "/etc/squid/domains-pre.lst" deny_info http://login.domain.com/ whitelist #deny_info ERR_ACCESS_DENIED whitelist http_access deny !whitelist http_access allow whitelist http_port 39135 transparent ## Debug Values access_log /var/log/squid/access-pre.log cache_log /var/log/squid/cache-pre.log # Production Values #access_log /dev/null #cache_log /dev/null # Set PID file pid_filename /var/run/gatekeeper-pre.pid SOLUTION: I believe I might have found a solution to this. After days and days trying to figure it out, only through a random stumble I found client_persistent_connections off server_persistent_connections off This did the trick. So it wasn't so much cache as it was a single persistent connection messing things up. W000T!

• GlusterFS on VMWare ESXi 5

  - by Dharmavir

  I want to build network file system on top of my VMWare ESXi based virtual nodes which are running Ubuntu 12.04 LTS. I am evalaluating options and found that GlusterFS (http://www.gluster.org/) can turn out to be a good choice. Purpose: I have about 2 dozen VM nodes with different configurations, on 2 physical nodes which has following configuration: 16 core Intel Xeon 1 TB 48 GB RAM Now as I said earlier each Physical server has about 1TB hdd and I can increase if I want additional so for now I have 2TB disk space available, these space is distributed in VM nodes I have created on which about 2 dozen VM nodes live. Now some of them being application server and mgmt server, they have plenty of free disk space which I want to utilize for some heavy storage which I can not design if I do that individually on single VM node. This way if my storage is distributed between dozens of VM nodes and about 2 or more physical nodes I have some sort of backup as well. I do not mind if data gets stored redundently but per my knowledge it might hapeen that individual VM nodes will not be able to store all of the data because complete data size for example if we take 100GB will exceed VM disk size of 70GB and then VM will also have system and program files on it. I need some suggestion that will GlusterFS be the solution for which I am looking forward to or I should go with something like hadoop? I am not too sure. But yes, I would like to utilize my free space on each VM node and while doing that if I get store data redundently I am okay because it will give me data security.

• Is it possible to skip .rvmrc confirmation?

  - by Viacheslav Molokov

  We are using RVM for managing Ruby installations and environments. Usually we are using this .rvmrc script: #!/bin/bash if [ ! -e '.version' ]; then VERSION=`pwd | sed 's/[a-z/-]//g'` echo $VERSION > .version rvm gemset create $VERSION fi VERSION=`cat .version` rvm use 1.9.2@$VERSION This script forces RVM to create new gem environment for each our project/version. But each time we was deploying new version RVM asks us to confirm new .rvmrc file. When we cd to this directory first time, we are getting something like: =============================================================== = NOTICE: = =============================================================== = RVM has encountered a not yet trusted .rvmrc file in the = = current working directory which may contain nasty code. = = = = Examine the contents of this file to be sure the contents = = are good before trusting it! = = = = Press 'q' to exit the reader when finished reading the file = =============================================================== (press enter to continue when ready) This is not as bad for development environments, but with auto deploy it require to manually confirm each new version on each server. Is it possible to skip this confirmation?

• Change the default route without affecting existing TCP connections

  - by Patrick Horn

  Let's say I have two public network addresses on my server: one NAT through an ISP (192.168.99.0/24), and a VPN through a different ISP (192.168.1.0/24), already configured with a per-host route to the VPN server through my ISP. Here is my initial routing table. I am currently routing through my ISP on subnet 192.168.99.0/24. $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.99.1 0.0.0.0 UG 0 0 0 eth1 55.66.77.88 192.168.99.1 255.255.255.255 UGH 0 0 0 eth1 192.168.99.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 Now, I want new TCP connections to switch to my 192.168.1.0/24 so I type the following: $ route add -net 0.0.0.0 gw 192.168.1.1 dev tap0 When I do this, it causes some long-standing TCP connections to hang. Is there a way to I safely change the default interface for new connections, while allowing existing TCP connections to use the old route (i.e. do I need enable some sort of stateful routing table)? I am okay with a solution that only works with established TCP connections, and I don't care how hacky it is. For example, if there is a way to add temporary iptables rules for existing connections to force them over the old route. But there has to be some way to do this. EDIT: Just a note about a simple "route add -host ... " for existing connections: this solution would work if I am fine with leaving a subset of IPs on the old interface. However, in my application, this actually doesn't solve my problem because I want to allow new connections to come on the new interface even if they have the same source IP. I'm now looking at using the "ip route" command to set source-based routing rules.

• Why do I get "Permission denied (publickey)" when trying to SSH from local Ubuntu to a Amazon EC2 server?

  - by Vorleak Chy

  I have an instance of an application running in the cloud on Amazon EC2 instance, and I need to connect it from my local Ubuntu. It works fine on one of local ubuntu and also laptop. I got message "Permission denied (publickey)" when trying to access SSH to EC2 on another local Ubuntu. It's so strange to me. I'm thinking some sort of problems with security settings on the Amazon EC2 which has limited IPs access to one instance or certificate may need to regenerate. Does anyone know a solution?
