  • esx5 debian VM vlan setup

    - by Kstro21
    i have a server with ESX5, have a switch with about 20 vlans, this is how setup the trunk port interface GigabitEthernet0/1/1 description ToOper port link-type trunk undo port trunk allow-pass vlan 1 port trunk allow-pass vlan 2 to 14 stp disable ntdp enable ndp enable bpdu enable then, i created a standar switch(sw1) using the vSphere Client, the VLAN ID is set to All (4095), i also created a VM with Debian 6, with a NIC connected to sw1, now, i want to configure this NIC for a selected group of vlans auto vlan10 iface vlan10 inet static address 11.10.1.0 netmask 255.255.255.224 mtu 1500 vlan_raw_device eth0 auto vlan14 iface vlan14 inet static address 11.10.1.65 netmask 255.255.255.248 mtu 1500 vlan_raw_device eth0 so, when i restart the network using /etc/init.d/networking restart, i got this error Reconfiguring network interfaces...SIOCSIFADDR: No such device vlan14: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device vlan14: ERROR while getting interface flags: No such device SIOCSIFMTU: No such device vlan14: ERROR while getting interface flags: No such device Failed to bring up vlan14. done. this is just part of the error, so, my questions is: is this possible?, i mean, what i'm trying to achieve using ESX Virtual Machines, VLANS, etc is this a Debian problem? can be solved? i've read about a file named z25_persistent-net.rules in Debian but it doesn't exist in my installation. in the In the vSphere Networking for ESX5 guide, you can read: If you enter 0 or leave the option blank, the port group can see only untagged (non-VLAN) traffic. If you enter 4095, the port group can see traffic on any VLAN while leaving the VLAN tags intact. So, in theory, it should work, right? Hope you can help me up with this one Thanks

  • Poor write performance on Debian server running NFS with 22TB exported JFS filesystem

    - by user143546
    I am currently running a debian server that is exporting a large JFS filesystem (22TB) over NFS (nfs-kernel-server.) When attempting to write to the NFS share, the performance is very poor. The 22TB disk is sitting on a NAS mounted using iSCSI. It will bust for a moment near expected line speed, and then sit idle for several seconds. Very little traffic measured in the low kb/sec. The wait peeks on write. When reading from the NFS mount, the system operates at expected speeds (11MB/sec). The issue does not occur when using SFTP, rsync, or local coping (non-nfs). The issue persists between stable and testing releases. On the same machine I have a 14TB ext4 filesystem using the exact same export configuration that does not share the issue. This share is not in regular use and thus not consuming resources. NFS Server: cat /etc/exports /data2 10.1.20.86(rw,no_subtree_check,async,all_squash) cat /sys/block/sdb/queue/scheduler noop [deadline] cfq cat /etc/default/nfs-kernel-server RPCNFSDCOUNT=8 RPCNFSDPRIORITY=0 RPCMOUNTDOPTS=--manage-gids NEED_SVCGSSD= RPCSVCGSSDOPTS= NFS Client: cat /etc/fstab 10.1.20.100:/data2 /root/incoming nfs rw,noatime,soft,intr,noacl 0 2 cat /sys/block/sdb/queue/scheduler noop [deadline] cfq cat /proc/mounts 10.1.20.100:/data2/ /root/incoming nfs4 rw,noatime,vers=4,rsize=262144,wsize=262144,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.1.20.86,minorversion=0,addr=10.1.20.100 0 0 This problem has me pretty stumped. Any help would be greatly welcomed. Thanks.

  • Installing Debian 7.1 on FakeRAID/Intel Z77 results in boot with no grub menu

    - by user198982
    I'm trying to install Debian 7.1 from DVD onto 2x500GB drives which are set up in a FakeRAID mirror using the on-board FakeRAID provided by the Z77 chipset. I have followed the guide here https://wiki.debian.org/DebianInstaller/SataRaid. Namely, I booted into the expert install with the 'dmraid=true' option added, installed onto the RAID mirror which the installer correctly detected, then installed grub2 onto /dev/mapper/.. raid volume. I chose to use LVM (so a boot partition + LVM volume). As per the guide, I have uncommented the "GRUB_DISABLE_LINUX_UUID=true" line in "/etc/default/grub" and ran "update-grub" then "grub-install /dev/mapper/.." (with the right RAID device in the command). However, after I rebooted the system, all I got was a grub console. It did not load the menu. I checked and it seems that it never even generated a menu file. I re-installed Debian a few times since, trying out different options and also a few workarounds people posted online, but to no avail. The best I am getting is a grub console. No menu. Some times it will generate the grub.cfg, some times it won't, depending on the workaround I try. I was wondering if anyone else has experienced this issue. There is no need to preach how I should not use FakeRAID. I have seen others trying to figure this out so I think a resolution to this issue would be of interest to more than just me. Also, I first installed the system onto a small drive for testing something else. I made a backup with Acronis and was able to restore that onto the RAID mirror by using Universal Restore. When I installed it onto a 500GB without RAID, backed up using the same method, then restored onto a RAID volume of the same size, it would not boot and I got grub errors. Weird. I can post more details, just let me know what you want to see.

  • Debian boot problems

    I've got Debian server with one disk. No dual boot or anything fancy. Just Debian 6.0 (Squeeze). I rebooted the server today and now it doesn't boot. I get the following (from GRUB): error: hd0,msdos out of disk I then get a grub prompt grub rescue> I've been googling for ages with no luck. /etc/fstab > #/etc/fstab: static file system information. > # > # <file system> <mount point> <type> <options> <dump> <pass> > aufs / aufs rw 0 0 > tmpfs /tmp tmpfs nosuid,nodev 0 0 I've run debian rescue mode and looked through the syslog.

  • High Load mysql on Debian server

    - by Oleg Abrazhaev
    I have Debian server with 32 gb memory. And there is apache2, memcached and nginx on this server. Memory load always on maximum. Only 500m free. Most memory leak do MySql. Apache only 70 clients configured, other services small memory usage. When mysql use all memory it stops. And nothing works, need mysql reboot. Mysql configured use maximum 24 gb memory. I have hight weight InnoDB bases. (400000 rows, 30 gb). And on server multithread daemon, that makes many inserts in this tables, thats why InnoDB. There is my mysql config.

  • DENY select on sys.dm_db_index_physical_stats

    - by steveh99999
    Technorati Tags: security,DMV,permission,sys.dm_db_index_physical_stats I recently saw an interesting blog article by Paul Randal about the performance overhead of querying the sys.dm_db_index_physical_stats. So I was thinking, would it be possible to let non-sysadmin users query DMVs on a SQL server but stop them querying this I/O intensive DMV ? Yes it is, here’s how… 1. Create a new login for test purposes, with permissions to access AdventureWorks database only … CREATE LOGIN [test] WITH PASSWORD='xxxx', DEFAULT_DATABASE=[AdventureWorks] GO USE [AdventureWorks] GO CREATE USER [test] FOR LOGIN [test] WITH DEFAULT_SCHEMA=[dbo] GO 2.login as user test and issue command SELECT  * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks'),NULL,NULL,NULL,'DETAILED') gets error :-  Msg 297, Level 16, State 12, Line 1 The user does not have permission to perform this action. 3.As a sysadmin, issue command :- USE AdventureWorks GRANT VIEW DATABASE STATE TO [test] or GRANT VIEW SERVER STATE TO [test] if all databases can be queried via DMV. 4. Try again as user test to issue command SELECT * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks '),NULL,NULL,NULL,'DETAILED') -- now produces valid results from the DMV.. 5 now create the test user in master database, public role only USE master CREATE USER [test] FOR LOGIN [test] 6 issue command :- USE master DENY SELECT ON sys.dm_db_index_physical_stats TO [test] 7 Now go back to AdventureWorks using test login and try SELECT * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks’),NULL,NULL,NULL,’DETAILED') Now gets error... Msg 229, Level 14, State 5, Line 1 The SELECT permission was denied on the object 'dm_db_index_physical_stats', database 'mssqlsystemresource', schema 'sys'. but the user is still able to query all other non-IO-intensive DMVs. If the user attempts to view the index physical stats via a builtin management studio report  – see recent blog post by Pinal Dave they get an error also

  • Firefox Furigana Injector on Debian

    - by Ken
    I'm using Iceweasel (un/rebranded Firefox) 3.5.9 on Debian (amd64). I want to use the "Furigana Injector" plugin. I installed it via the Tools - Add-ons menuitem (version 1.3), and restarted Firefox. Unfortunately, when I click the button, it only says: "The 'SimpleMecab' XPCOM component could not be loaded." in a dialog box, several dozen times (!). I found a Debian package "libmecab1", but installing it didn't help. Is there some "mecab" package I can install that will make this work?

  • Debian 3.1 (Sarge) init.d boot order

    - by Adam Lewis
    I am using a TS-7800 single board computer from Technologic Systems that ships with Debian 3.1 (Sarge). I have updated it to Squeeze, but due to various driver issues I have been forced to roll back to Sarge. I am attempting to configure the various drivers and configurations needed for my application services before they start. Ideally I would call one init.d script that contains the drivers / configurations then call the other init.d scripts (one for each process). I am left scratching my head on how to guarantee the boot sequence. I know in later versions of Debian I could use the lbs-header to achieve this; but is there anything comparable to the LBS header in Sarge?

  • OS choice between: Debian, gNewSense, and OpenSolaris

    - by penyuan
    I am planning to migrate from Mac OS X and Windows to either a Unix or Linux distribution, i.e. I am a Linux/Unix beginner. Right now the following caught my interest: Debian: Well established with huge repository of 20000+ apps. gNewSence: "Totally free" version of Ubuntu, so it should be more beginner friendly? OpenSolaris: Also open-source, and built on "strong" Unix base. I do mainly basic tasks such as web browsing, office work, maintaining big photo collection, and a little bit of programming. Questions: How "free" are each of these distributions compared to each other, is this whole freedom thing a big deal? Will a binary labeled as for Ubuntu work on gNewSense? What are simple IDEs for Debian and gNewSense?

  • Can't install new database in OpenLDAP 2.4 with BDB on Debian

    - by Timothy High
    I'm trying to install an openldap server (slapd) on a Debian EC2 instance. I have followed all the instructions I can find, and am using the recommended slapd-config approach to configuration. It all seems to be just fine, except that for some reason it can't create my new database. ldap.conf.bak (renamed to ensure it's not being used): ########## # Basics # ########## include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/nis.schema include /etc/ldap/schema/inetorgperson.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel none modulepath /usr/lib/ldap # modulepath /usr/local/libexec/openldap moduleload back_bdb.la database config #rootdn "cn=admin,cn=config" rootpw secret database bdb suffix "dc=example,dc=com" rootdn "cn=manager,dc=example,dc=com" rootpw secret directory /usr/local/var/openldap-data ######## # ACLs # ######## access to attrs=userPassword by anonymous auth by self write by * none access to * by self write by * none When I run slaptest on it, it complains that it couldn't find the id2entry.bdb file: root@server:/etc/ldap# slaptest -f ldap.conf.bak -F slapd.d bdb_db_open: database "dc=example,dc=com": db_open(/usr/local/var/openldap-data/id2entry.bdb) failed: No such file or directory (2). backend_startup_one (type=bdb, suffix="dc=example,dc=com"): bi_db_open failed!

It doesn't resolve the underlying problem: root@server:/etc/ldap# slaptest -f ldap.conf.bak -F slapd.d -u config file testing succeeded Looking in the database directory, the basic files are there (with right ownership, after a manual chown), but the dbd file wasn't created: root@server:/etc/ldap# ls -al /usr/local/var/openldap-data total 4328 drwxr-sr-x 2 openldap openldap 4096 Mar 1 15:23 . drwxr-sr-x 4 root staff 4096 Mar 1 13:50 .. -rw-r--r-- 1 openldap openldap 3080 Mar 1 14:35 DB_CONFIG -rw------- 1 openldap openldap 24576 Mar 1 15:23 __db.001 -rw------- 1 openldap openldap 843776 Mar 1 15:23 __db.002 -rw------- 1 openldap openldap 2629632 Mar 1 15:23 __db.003 -rw------- 1 openldap openldap 655360 Mar 1 14:35 __db.004 -rw------- 1 openldap openldap 4431872 Mar 1 15:23 __db.005 -rw------- 1 openldap openldap 32768 Mar 1 15:23 __db.006 -rw-r--r-- 1 openldap openldap 2048 Mar 1 15:23 alock (note that, because I'm doing this as root, I had to also change ownership of some of the files created by slaptest) Finally, I can start the slapd service, but it dies in the attempt (text from syslog): Mar 1 15:06:23 server slapd[21160]: @(#) $OpenLDAP: slapd 2.4.23 (Jun 15 2011 13:31:57) $#012#011@incagijs:/home/thijs/debian/p-u/openldap-2.4.23/debian/build/servers/slapd Mar 1 15:06:23 server slapd[21160]: config error processing olcDatabase={1}bdb,cn=config: Mar 1 15:06:23 server slapd[21160]: slapd stopped.

Unfortunately, syslog isn't reporting a specific error in this case (if it were a file permission error, it would say). I've tried uninstalling and reinstalling slapd, changing permissions, Googling my wits out, but I'm tapped out. Any OpenLDAP genius out there would be greatly appreciated!

  • Dedicated server configuration - some tips -Xenserver/Debian

    - by Sanjay S
    I am migrating from a vps based hosting to a dedicated hosting (8GB RAM/1TB HD). I need to run multiple Drupal and Ruby based applications? what would be the recommended configuration. I was thinking of two options. 1) Install multiple Debian os on top of Xen (like VPS). Each may be 2GB Memory and run Drupal and Ruby and MYSQL on separate partitions . 2) Install one instance of Debian. and Install Drupal (Apache, php) Ruby (lighttpd, ruby) ,MySQL all in the same partition I was little worried that option 2 could lead to some performance issues later..

  • Debian as USB hardware portable as possible

    - by James Mitch
    I have recent hardware, 64 bit, pae and so on. But I'd like to have my Debian installation on a USB HDD. Installing Debian to USB is solved. I used the i386 architecture image. But a pae kernel has been installed. I want to be able to travel with my USB HDD and therefore I want best possible hardware compatibility. My friends and family have sometimes older hardware, but always i386, just sometimes without 64 bit or pae. Never met someone with sparc or other architectures. What should I do to get non-pae kernel and maximum hardware compatibility?

  • Linux Debian Security Breach - what now? [closed]

    - by user897075
    Possible Duplicate: My server's been hacked EMERGENCY I installed Debian (Squeeze) a while back in my home network to host some personal sites (thank god). During the installation it prompted me to enter a user other than root - so in a rush I used my name as user and pass (alex/alex for what its worth). I know it's horrible practice but during the setup of this server I'm always logged in as root to perform configurations, etc. Few days or a week passes and I forget to change the password. Then I finally get my web site finished and I open the port forwarding on my router and DynDNS to point to my server in my home. I've done this many times in the past never had issues but I use a cryptic root password and I guess disabled regular accounts. Today I reformat my Windows 7 and after spending all day tweaking and updating SP1 I look for cloning apps and find clonezilla and see it supports SSH cloning, so I go through the process only to discover I need a user, so I log into my web-server and see I have the user 'alex' already in and realize I don't know the password. So I change the password to something cryptic and visit the directory 'home' only to realize their are contents such as passfile, bengos, etc. My heart sinks, I've been hacked!!! Sure as hell there are all sort of scripts and password files. I run a 'last' command and it seems they last logged in april 3rd. Question: What can I do to see if they did anything destructive? Should I reformat and reinstall? How restrictive is Debian/Squeeze in terms of user permissions out of the box - all my personal website stuff was created using 'root' so changing files does not seem to have occured. How did they determine there was a user 'alex' on the machine? Can you query any machine and figure this out? What the users are? Looks like they tried to run a IP scan...other nodes on the network are running Windows 7. One of which seems a little wonky as of late - is it possible they buggered up that system? What corrective action can I take to avoid this from happening again? And figure out what might have changed or been hacked? I'm hoping debian out of box is fairly secure and at best he managed to read some of my source code. :p Regards, Alex

  • PHP-FPM for nginx on debian

    - by Jelko
    What is the preferred/recommended way of installing php-fpm on debian for use with nginx? I read about a "php5-fpm" package everywhere, but it's not available in the official debian repos any more. The PHP-FPM website (http://php-fpm.org/download/) says that fpm is now included with the php core. Is it enough to install "php5-common" then? Where are the config files, though? Other people recommend to install the current version of php and php-fpm from dotdeb.org. The versions provided there are generally more up to date. But is it secure? Is this a good repo to use in a production environment? I would appreciate any advice.

  • Recovering/Creating NewWorld Partition on Mac G4 (PPC) after botched Debian Install

    - by Luis Espinal
    I was trying to install Debian 5.04 on a Mac G4, and in typical geek tradition, I didn't RTFM. During installation, I nuked all existing partitions, creating new to my liking. But as I learned later during the installation process, yaboot needed a NewWorld partition, so I can't boot the installation. I don't have any OSX CDs with me (this is a used G4 I purchased of craigslist) with which to create a HFS partition. I've re-run the Debian installer, which lets me create a partition that is supposed to be of type 'NewWorld', but the installer does not seem to like it or recognizes it. Any ideas how to proceed from here? Thanks.

  • Debian on Hyper-V

    - by Tobia
    I installed Debian with kernel 2.6.32-5-686 on a Hyper-V virtual machine. I had to add a legacy network card. I follow this tutorial http://www.microsofttranslator.com/bv.aspx?ref=Internal&from=ru&to=en&a=http://blogs.technet.com/b/abeshkov/archive/2011/03/17/hyperv_5f00_debian.aspx to add Hyper-V driver but when I reboot with the new kernel it crash during bootup. Is there any other way to load hyper-v drivers? I really need to change that legacy network card because my debian machine is going to be used as proxy. Thank you.
