• Shrink a Volume Group in LVM / Linux in order to install Windows on the freed space

  - by Stephan Kristyn

  I have a Volume Group with Unused space. This 40Gig should become an entidy in order to install Microsoft windows 7 on it. I do not have extra space on the drive - that is why I want to shrink the VG! LVG berta resides on sda2 and consists of lv_root lv_swap unused_space I want it to become lv_root lv_swap and have a seperate entidy made out of unused_space. Microsoft Windows 7 has to get installed on this entidy. I do not understand why Linux made simple things complicated. I utterly hate LVM and think its absolute bollocks. Useful Sources: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-system-config-lvm.html Edit: I found the answer. The necessary steps depict how complicated LVM really is. In my opinion it is best to avoiding LVM until pvresize matures as promised in its man pages. Answer: http://fedorasolved.org/Members/zcat/shrink-lvm-for-new-partition If you run into problems when you want to remove lvswap even if in resuce mode, then try swapoff /dev/vg_1/lv_swap lvchange -an /dev/vg_1/lv_swap

• Problem restoring from tar backup: why are there /dev/disk/by-id/ symlinks and how can I avoid them?

  - by SK.

  Hello, I'm trying to make a bare-bone backup system with the most basic tools available on openSUSE 11.3 (in this case: bash, fdisk, tar & grub legacy) Here's the workflow for my scripts: backup.sh: (Run from external system, e.g. LiveCD) make an fdisk script ($fscript) from fdisk -l's output [works] mount the partitions from the system's fstab [works] tar the crucial stuff in file.tgz [works] restore.sh: (Run from external system, e.g. LiveCD) run fdisk $dest < $fscript to restore partitioning [works] format and mount partitions from system's fstab [fails] extract from file.tgz [works when mounting manually] restore grub [fails] I have recently noticed that openSUSE (though I'm sure it has nothing to do with the distro) has different output in /etc/fstab and /boot/grub/menu.lst, more precisely the partition name is for example "/dev/disk/by-id/numbers-brandname-morenumbers-part2" instead of "/dev/sda2" -- but it basically is a simple symlink. My questions about this: what is the point of such symlinks, especially if we're restoring on a different disk? is there a way to cleanly prevent the creation of those symlinks and use the "true" /dev/sdx everywhere instead? if the previous is no, do you know a way to replace those symlinks on the fly in a text file? I tried this script but only works if the file starts with the symlink description (case of fstab, not menu.lst): ### search and replace /dev/disk/by-id/... to /dev/sdx while read oldVolume rest; do # get first element, ignore rest of line if [[ "$oldVolume" =~ ^/dev/disk/by-id/.*(-part[0-9]*$)? ]]; then newVolume=$(readlink $oldVolume) # replace pointer by pointee, returns "../../sdx" echo /dev/${newVolume##*/} $rest >> TMP # format to "/dev/sdx", write line else echo $oldVolume $rest >> TMP # nothing to do fi done < $file mv -f TMP $file # save changes I've had trouble finding a solution to this on google so I was hoping some of the members here could help me. Thank you.

• Disable the user of Internet explorer through policies when called from HTML help

  - by Stephane

  Hello, I have a locked down environment where users are prohibited from doing, well, basically anything but run the specific programs we specify. We just switched a program from using the venerable "WinHELP" help format to HTML help (CHM) but that seem to have an unwanted and rather dangerous side effect: when a user click on a hyperlink inside the HTML help, a new internet explorer window is opened and the user is free to browse and do terrible things to my server (well, not that much, but still...) I have checked the session in this case and the IE window is actually hosted within the help engine: there is no iexplore.exe process running in the user session (and it cannot: it's explicitly prohibited). We have disable all help right now until we find a solution. I'm working with the help team to have all external URLs removed from the help file but that is going to be a long and error-prone task. Meanwhile, I've checked all the group policies option but I have to say that I was unable to find anything that would prevent a standalone IE window hosted in a random process from running. I don't want to disable WinHTTP or the IE rendering engine or anything of the sort. But I need to prevent all users members of a specific AD user group from ever having an IE window displayed to them. The servers are running Windows 2003 and Citrix metaframe 4.5. Thanks in advance

• Is there a program to show programs loading during the boot process in real time?

  - by Gary M. Mugford

  Hi all, There are any number of programs that will show me WHAT will run during the boot process for Windows XP. I've always been partial to Mike Lin's version but there are several others, some of which are quite possibly superior. That's not the issue. What I'd really like is a program that would load first and then would list the programs that were about to load and then check them off as the programs loaded. This isn't something I necessarily need for myself. But certain family members get click happy as soon as they see the icon they eventually want to run and end up clicking on it. THIRTY TWO TIMES in one memorable crash-inducing spasm. If there was some way for 'progress' to be shown during the loading of from the various spots Windows auto-loads from, PLUS a BIG BANNER saying "Please do not move the mouse or click on anything until done.", I think I might cut down on my early morning family support calls significantly. I've tried a variety of searches, but I couldn't find the ones that show in real time in the forest of links to programs that will show the list after the fact. Any leads? If not, do any of you who write the after-the-fact listers want to take a shot at producing a utility to do what I think would be a relatively popular utility? Best of the season to all of you and yours. Thanks in advance for any replies, GM

• su not giving proper message for restricted LDAP groups

  - by user1743881

  I have configured PAM authentication on Linux box to restrict particular group only to login. I have enabled pam and ldap through authconfig and modified access.conf like below, [root@test root]# tail -1 /etc/security/access.conf - : ALL EXCEPT root test-auth : ALL Also modified sudoers file, to get su for this group <code> [root@test ~]# tail -1 /etc/sudoers %test-auth ALL=/bin/su</code> Now, only this ldap group members can login to system. However when from any of this authorized user, I tried for su, it asks for password and then though I enter correct password it gives message like Incorrect password and login failed. /var/log/secure shows that user is not having permission to get the access, but then it should print message like Access denied.The way it prints for console login. My functionality is working but its no giving proper messages. Could anyone please help on this. My /etc/pam.d/su file, [root@test root]# cat /etc/pam.d/su #%PAM-1.0 auth sufficient pam_rootok.so # Uncomment the following line to implicitly trust users in the "wheel" group. #auth sufficient pam_wheel.so trust use_uid # Uncomment the following line to require a user to be in the "wheel" group. #auth required pam_wheel.so use_uid auth include system-auth account sufficient pam_succeed_if.so uid = 0 use_uid quiet account include system-auth password include system-auth session include system-auth session optional pam_xauth.so

• Affordable combined Ruby/Rails/Redmine + Subversion hosting?

  - by Pekka

  I'm a self employed web developer and after nine years of hard work, I'm looking to become a bit more "vagrant" starting next year, do some much-needed traveling and a bit and work off and on, making use of one of the greatest advantages of a programming job: The ability to work virtually from everywhere. For that, I am looking for a reliable hosting company I can entrust my code to in the form of a number of Subversion repositories, and an installation of the Redmine project management tool. As my financial situation may vary during traveling, I am looking for something I can pay up front for a year or two, and is obviously not too pricey. I don't care where the company is located, as long as it's trustworthy and solid, meaning it's not likely to go out of business next month. Does anybody know good recommendations? Preferably from own, personal, good experience. I have looked at CVSDude / Codesion and while they are certainly great, they don't offer Redmine of course, and seem to be aiming toward bigger organizations mainly. What I would need: 2-5 Gigs of space minimum, freely distributable between SVN, and Redmine attachments Unlimited number of Subversion projects Access control (team members / checkout-only accounts / etc.) I don't mind configuring the svn settings on file basis myself I need the possibility to map a custom domain to the package that is hosted elsewhere Frequent backups and access to those backups through FTP or other means I have been running my own virtual server for this until now, but I don't want the hassle, especially on the security side, while I may not always have the internet connection to fix problems that may come up.

• Hosting a server for websites, ftp and random use at home?

  - by Zolomon

  I'm wondering what's the best option for me if I want to move all my hosted websites (from a hosting company) to a server at my own home? Basically, the needs I have are: be able to host websites using PHP/ASP.NET (haven't really decided yet - both would be preferred!) enable FTP so I can create accounts for my family members to access the server for file handling SSH SSL - for secure connections (this is something you have to buy/apply for per domain, not sure if there are any server side settings that have to be made) be able to stream video remote desktop host home-brew applications that can run as services use either MySQl/SQLite/SQL for relational database storage What should I think of before I buy a server? What hardware will I need, what will limit my server? I basically want to learn networking better as I'm a software and web developer but haven't had the resources to acquire any serious toys until now. At the time of writing, most of my websites have 60 visits/day so I don't suspect them to be very demanding. Is there something I haven't thought of that I should have? What OS would you suggest I run? FreeBSD vs Windows Server vs ?

• Why is it necessary to chmod o+r parent directory to fix 403 access forbidden error with Nginx and P

  - by davenolan

  This may be an Nginx wrinkle, or it may be because I don't understand Unix permissions. We're using Hudson CI to deploy our staging instance. So RAILS_ROOT is /var/lib/hudson/jobs/JOBNAME/workspace. Hudson runs as hudson user Nginx runs as www-data user hudson and nginx are both members of the www group root of my nginx conf points to RAILS_ROOT/public as per normal. RAILS_ROOT/config/environment.rb is owned by www-data (so Passenger runs as www-data) RAILS_ROOT and everything in it is owned by the www group and group has r/w/x permissions As it stood, Nginx threw 403 permission denied when requesting any url. error.log contained entries like this: public/index.html" is forbidden (13: Permission denied). These did not fix the or change the error (each with a stop/start of Ngnix): chmod 777 -R RAILS_ROOT chgrp www -R /var/lib/hudson I also tried Nginx as root, and passenger complained that it could not find config/environment (despite the path displayed on the error page being correct). The fix was to ensure everybody has read permissions on each directory in the heirachy. In this case chmod o+r /var/lib/hudson. But if the group has read permissions on the directory, and nginx is a member of the owner group of the directory, why was it necessary to allow everyone read permissions? Is there something have not grokked about permissions? $nginx -V nginx version: nginx/0.7.61 built by gcc 4.4.1 (Ubuntu 4.4.1-4ubuntu8) configure arguments: --prefix=/opt/nginx --add-module=/usr/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/nginx --with-http_ssl_module --with-pcre=~/src/pcre-8.00/ --with-http_stub_status_module $cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=9.10 DISTRIB_CODENAME=karmic DISTRIB_DESCRIPTION="Ubuntu 9.10"

• Centos Server/MySQL server problem

  - by Jake

  Hello all, I currently run a website we get about 15,000-20,000 hits a day. We currently run a very active forum, that is hosted using Vbulletin software. We have 4.5 Million Posts, 80,000 Threads, with about 11,000 members of which just under a third is active all the time. Now I am running a Intel Xeon Quad Core (2.13Ghz) with 4GB of RAM, Centos 5.5 and running DirectAdmin on the box to manage it. I also run the current stable version of Apache, MySQL, and php. This is the only site that is hosted on this machine. Now during random times of day sometimes when it gets busy the server load can get to like 20, but this can also happen when we only have like 200 users active too. I dont understand what is causing these problems. Sometimes I get pages that can generate in .2 seconds other times it takes like 5-8 seconds. I have customized the my.cnf file and that has not helped out anything, I didnt know where else to turn so if anyone has any suggestions please let me know. Thank You In advance.

• Window 7 Host does not answer to ping

  - by gencha

  Today I tried printing on a shared printer on one of our homegroup members. Sadly it did not work (printer marked as offline). Shortly after, I noticed I can't even ping the machine that owns the printer (I also can not remotely access it in any other way I've tried). Currently I'm trying to ping the machine from the router both computers are connected to (and my machine in question doesn't answer). I do receive the echo requests (as verified with WireShark). I also added a rule in the Windows Firewall to specifically allow ICMP echo requests, but that didn't change anything. I also tried netsh firewall set icmpsetting 8 enable, but that didn't change anything either. Completely disabling the Windows Firewall has no effect on the issue either. One has to wonder, where does Windows log when and why it ignored any incoming packets? How can I get to the bottom of this? Here are some ways I found to dig deeper into the issue: Enabling logging on the Windows Firewall Enabling Windows Filtering Platform Auditing Both methods at least give more insight into the issue. The plain log file is full of entries like this: 2011-11-11 14:35:27 DROP ICMP 192.168.133.1 192.168.133.128 - - 84 - - - - 8 0 - RECEIVE So the ICMP packets are being dropped as if that was intended. The Event Viewer now gives a little bit more details: The Windows Filtering Platform has blocked a packet. Application Information: Process ID: 4 Application Name: System Network Information: Direction: Inbound Source Address: 192.168.133.1 Source Port: 0 Destination Address: 192.168.133.128 Destination Port: 8 Protocol: 1 Filter Information: Filter Run-Time ID: 214517 Layer Name: Receive/Accept Layer Run-Time ID: 44 This same entry is always repeated with 2 points of information changing: Process ID: 420 Application Name: \device\harddiskvolume2\windows\system32\svchost.exe The service host with the PID 420 is the host for the following services: Windows Audio DHCP Client Windows Event Log HomeGroup Provider TCP/IP NetBIOS Helper Security Center Additionally, there is currently this problem with the same machine: Even though my network is set to be a "Home network", I am unable to create a new homegroup.

• dns in a small network with router and AD domain

  - by Felix

  I have a small office network with router (running OpenWRT), Windows Domain Controller (used to be 2008R2; I just backed it up and upgraded to 2012), about a dozen AD clients (3 server and windows workstation) and several non-AD clients (network printer, PBX). The problem is that the clients can't access servers by name (only by IP). I tried all kind of permutations. Right now domain controller runs DNS server for all desktops; but unless I put an entry in hosts file - I can only get by IP. I have router as DHCP server (since not all devices are on AD); and except for Domain Controller all IP addresses, including "static", are assigned by the router. Most frustrating, some servers sometimes just work! for example, I can often get to the Linux box by name (it is part of Domain using Beyond Trust Integration Services); but I can never get to SQL Server box. Seems like non-domain devices see more names than domain members... This network should be fairly typical; but I couldn't get any guidance about how to set up DNS/DHCP service to make all nodes happy. The closest is this question, but still it's different! Thanks

• SharePoint extranet security concerns, am I right to be worried?

  - by LukeR

  We are currently running MOSS 2007 internally, and have been doing so for about 12 months with no major issues. There has now been a request from management to provide access from the internet for small groups (initially) which are comprised of members from other Community Organisations like ours. Committees and the like. My first reaction was not joy when presented with this request, however I'd like to make sure the apprehension is warranted. I have read a few docs on TechNet about security hardening with regard to SharePoint, but I'm interested to know what others have done. I've spoken with another organisation who has already implemented something similar, and they have essentially port-forwarded from the internet to their internal production MOSS server. I don't really like the sound of this. Is it adviseable/necessary to run a DMZ type configuration, with a separate web front-end on a contained network segment? Does that even offer me any greater security than their setup? Some of the configurations from a TechNet doc aren't really feasible, given our current network budget. I've already made my concerns known to management, but it appears it will go ahead in some form or another. I'm tempted to run a completely isolated, seperate install just for these types of users. Should I even be concerned about it? Any thoughts, comments would be most welcomed at this point.

• opath syntax to force dynamic distribution group field as numerical comparison? (Exchange 2010)

  - by Matt

  I'm upgrading a (working) query based group (Exchange 2003) to a new and 'improved' dynamic distribution group (2010). For better or worse, our company decided to store everyone's employee ID in the pager field, so it's easy to manipulate via ADUC. That employee number has significance, as all employees are in a certain range, and all contractors are in a very different range. Basically, the new opath syntax appears to be using string compare on my pager field, even though it's a number. Let's say my employee ID is 3004, well, it's "less than" 4 from a string check POV. Set-DynamicDistributionGroup -Identity "my-funky-new-group" -RecipientFilter "(pager -lt 4) -and (pager -like '*') -and (RecipientType -eq 'UserMailbox')" Shows up in EMC with this: ((((((Pager -lt '4') -and (Pager -ne $null))) -and (RecipientType -eq 'UserMailbox'))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox'))) This group should have max of 3 members right? Nope - I get a ton because of the string compare. I show up, and I'm in the 3000 range. Question: Anyone know a clever way to force this to be an integer check? The read-only LDAP filter on this group looks good, but of course it can't be edited. The LDAP representation (look ma, no quotes on the 4!) - Also interesting it sort of 'fills the' bed with the (pager=4) thing... (&(pager<=4)(!(pager=4))(pager=*)(objectClass=user)(objectCategory=person)(mailNickname=*)(msExchHomeServerName=*)(!(name=SystemMailbox{*))(!(name=CAS_{*))!(msExchRecipientTypeDetails=16777216))(!(msExchRecipientTypeDetails=536870912))(!(msExchRecipientTypeDetails=8388608))) If there is no solution, I suppose my recourse is either finding an unused field that actually will be treated as an integer, or most likely building this list with powershell every morning with my own automation - lame. I know of a few ways to fix this outside of the opath filter (designate "full-time" in another field, etc.), but would rather exchange do the lifting since this is the environment at the moment. Any insight would be great - thanks! Matt

• Windows Server - share files without access for administrator

  - by Pawel

  We have a MS Windows Server 2008 R8 based server that is administrated by our IT department. We would like to achieve two things simultaneously: A folder on the server, containing several thousand files (new files added frequently) that is accessible to some ActiveDirectory users (e.g. board of directors) but is not accessible by IT department employees IT department employees still maintain rights to administrate the server, including installing new software and services We already checked some solutions: Using NTFS access rights. Unfortunately IT (members of "Administrators" group) can set themselves as new owners of the files and change the permissions so that they gain access to the files. Enabling EFS. Unfortunately even if you do not allow IT to access files, they still can disable EFS completely because they have administrative rights. Moreover as far as I know you have to manually add permissions for all users but the owner for each new file - very inconvenient. Creating a new role for the IT department that has all the privileges apart from taking ownership of files. Unfortunately if you're not a member of the Administrators group, you cannot install new software, no matter what privileges you add to the role. TrueCrypt - nice free encryption software, but with poor sharing capabilities. You can either mount an encryption container on the server (and then IT has access to its contents) or you mount them locally but only one user can mount it for writing. AxCrypt - free encryption software that enables file-by-file encryption on the server. There are some disadvantages though - you have to manually encrypt each new file added. The files have their extensions changes. You can only set one password for all files (so all users have to know this one password). Any other ideas? Our budget is limited so enterprise-class software from Symantec or PGP would probably be not an option.

• Restrict SSH user to connection from one machine

  - by Jonathan

  During set-up of a home server (running Kubuntu 10.04), I created an admin user for performing administrative tasks that may require an unmounted home. This user has a home directory on the root partition of the box. The machine has an internet-facing SSH server, and I have restricted the set of users that can connect via SSH, but I would like to restrict it further by making admin only accessible from my laptop (or perhaps only from the local 192.168.1.0/24 range). I currently have only an AllowGroups ssh-users with myself and admin as members of the ssh-users group. What I want is something that works like you may expect this setup to work (but it doesn't): $ groups jonathan ... ssh-users $ groups admin ... ssh-restricted-users $ cat /etc/ssh/sshd_config ... AllowGroups ssh-users [email protected].* ... Is there a way to do this? I have also tried this, but it did not work (admin could still log in remotely): AllowUsers [email protected].* * AllowGroups ssh-users with admin a member of ssh-users. I would also be fine with only allowing admin to log in with a key, and disallowing password logins, but I could find no general setting for sshd; there is a setting that requires root logins to use a key, but not for general users.

• Terminal Server in Windows Server 2003

  - by Hemal

  I have a confusion regarding what I am doing here. At present I have a Windows Server 2003 server with SP2. I have assigned RAS/VPN server role to it (through Manage my server wizard) and in my router, I setup the IP address of my RAS/VPN server as PPTP server. Staff leave their workstations ON all the time and access them from home through RDP. They first connect thorugh VPN & in the RDC they simply type their respective IP or computer name to access the office network from home. Everything works fine so far except: Staff have to leave compuers always ON in the office Speed is very slow depend how many staff members access the VPN network I was told to install and configure Terminal service to improve this situation. I already added TS Role in the server but I don't know how to clients can access the TS server from home or remote location. I really appreciate any good links or guidence from the experts in this group regarding this. Thank you in advance for any replies!

• Forcing users to change password on first login - Windows Server 2008 R2 Remote Desktop Services

  - by George Durzi

  I'm setting up a demo lab environment in which each demo lab user is assigned 4 accounts to use in the lab. Users access the lab via Remote Desktop to the "client" machine in the lab - exposed at demolab.mydomain.com. The Client machine is a Windows 2008 Server R2 Enterprise Edition server The Remote Desktop Services role is configured on this server Remote Connection settings are configured to allow users to connect with any version of the Remote Desktop Client All accounts are members of the local Administrators and Remote Desktop Users groups All accounts are configured to be forced to change the default password after first login The user is instructed to remote into the lab with an account designated as their main account, and establish 3 more remote desktop sessions within the lab using their 3 other assigned demo lab accounts. When establishing the initial remote desktop connection to the lab using their main account, the user sees the change password dialog as expected. However, after logging in and trying to establish remote desktop connections to the server with their three other accounts, they are prompted that they need to change the password after logging in but can't continue with the login process - they don't see the expected change password experience. After logging in with a primary accounts, it doesn't make a difference if I try establishing a Remote Desktop connection to the environment using the name of the server, e.g. Client, or demolab.mydomain.com. I experimented with changing the settings for Remote Connections to require NLA but that didn't make a different. Appreciate any tips. Thanks

• Cisco 3560+ipservices -- IGMP snooping issue with TTL=1

  - by Jander

  I've got a C3560 with Enhanced (IPSERVICES) image, routing multicast between its VLANs with no external multicast router. It's serving a test environment where developers may generate multicast traffic on arbitrary addresses. Everything is working fine except when someone sends out multicast traffic with TTL=1, in which case the multicast packet suppression fails and the traffic is broadcast to all members of the VLAN. It looks to me like because the TTL is 1, the multicast routing subsystem doesn't see the packets, so it doesn't create a mroute table entry. If I send out packets with TTL=2 briefly, then switch to TTL=1 packets, they are filtered correctly until the mroute entry expires. My question: is there some trick to getting the switch to filter the TTL=1 packets, or am I out of luck? Below are the relevant parts of the config, with a representative VLAN interface. I can provide more info as needed. #show run ... ip routing ip multicast-routing distributed no ip igmp snooping report-suppression ! interface Vlan44 ip address 172.23.44.1 255.255.255.0 no ip proxy-arp ip pim passive ... #show ip igmp snooping vlan 44 Global IGMP Snooping configuration: ------------------------------------------- IGMP snooping : Enabled IGMPv3 snooping (minimal) : Enabled Report suppression : Disabled TCN solicit query : Disabled TCN flood query count : 2 Robustness variable : 2 Last member query count : 2 Last member query interval : 1000 Vlan 44: -------- IGMP snooping : Enabled IGMPv2 immediate leave : Disabled Multicast router learning mode : pim-dvmrp CGMP interoperability mode : IGMP_ONLY Robustness variable : 2 Last member query count : 2 Last member query interval : 1000

• Monitoring AWS Systems Behind ElasticBeanStalk

  - by A. Avadis

  So I'm getting a company set up in the Amazon Cloud -- creating IAAS protocol/solutions/standardized implementation, etc while also being the SysAdmin for individual systems, app environments, and day-to-day uptime. One of the biggest issues I'm having is tracking various system/application logs, as well as logging/monitoring/archiving system metrics like memory usage, cpu usage, etc etc In a centralized fashion. E.g. -- Nagios + Urchin. The BIGGEST impediment to my endeavors is the following: The company application is deployed in the form of a Java *.WAR file, uploaded to an Elastic BeanStalk application environment, load balancing and auto-scaling between 3(min) and 10(max) servers, and the EC2's that run the application are fired up and disposed of ad-hoc. That is to say, I can't monitor the individual EC2's for very long because so many are being terminated then auto-provisioned/auto-scaled on the fly -- so I'd constantly be having to "monitor what I'm monitoring", and continuously remove/add EC2 machine addresses to my monitoring lists. IS there some sort of way to use monitoring tools like Zabbix or Nagios to monitor the ElasticBeanStalk, and have it automatically add on new EC2's, and remove terminated/failed EC2's from its monitoring list automatically? Furthermore, is there anything I can do with GrayLog to achieve similar results with the aggregation/centralization of my application logs from multiple EC2 instances into ONE consolidated set of logs/events? If not GrayLog, is there ANYTHING LIKE GrayLog that can automatically detect what EC2 members are being added/removed from the environment, and collect the logs from them automatically? Any and all advice or direction is appreciated. Thanks much, and cheers!!

• Contacts in Outlook 2003/2007, some questions

  - by Ernst

  If I create a distribution list and then select members, can I see different fields than the default ones? In 2007 there are radio buttons for 'name only' and 'more columns', but the latter does seem to only result in no results at all, regardless of which address book I choose. In 2003 there is no such thing. Is there a plug in that will break up the recipients (whether they be to, cc, or bcc) in groups of X, and send then a number of mails as required? Our host allows only 50 recipients per mail and only 300 total recipients per 5 minutes. I know the email client blat has exactly this functionality, but it does not seem to be able to connect to the exchange server to get the contacts needed. Could I maybe set outlook to send to blat which then does the breaking up as necessary? Can I (or is there a plug in for this) export only part of the contacts instead of all of them? Note that we send mail outside our organisation via our web host where we've got a few mailboxes, and we use our exchange (2000) server only internally, the few people that can send email to the outside world have an external mailbox as well as their exchange account defined. I might be able to convince our general boss that we can simply give (some) people the ability to send outside via exchange, but I might just as well not succeed. Alternatively, is there another program that can connect to exchange to get the contacts (selected based on categories) and then send via smtp in groups with delays between the mails?

• Delegating account unlock rights in AD

  - by ewall

  I'm trying to delegate the rights to unlock user accounts in our Active Directory domain. This should be easy, and I've done it before... but every time the user tries to unlock an account (using the LockoutStatus tool), he gets denied with the error "You do not have the necessary permissions to unlock this account." Here's what I've done: I created a domain local group and added the members who should have the rights. This was created over a week ago, so the users have logged out and in again. In ADUC, I've used the Delegate Rights wizard on the OU which contains our user accounts to grant permissions to Read lockoutTime and Writer lockoutTime to the group, per MSKB 279723 I have double-checked the permissions were applied correctly in ADSIEdit. I have forced replication between all domain controllers to ensure the permission changes were copied over. The user testing it has logged out and in again to ensure he has any changes applied to his account. ...That covers all the bases I can think of. Anything else I could be missing?

• Procurve Primary VLAN

  - by fukawi2

  I'm trying to depreciate usage of VLAN 1 on my ProCurve switches; 1 is unused. I understand that VLAN 1 must exist, but I want to remove it from all ports, especially trunks between switches. The problem I have is that stacking does not seem to work without VLAN 1. I have changed the primary VLAN and management VLAN on all the switches: (config)# primary-vlan 42 (config)# management-vlan 42 (config)# no vlan 1 untagged 25 Port 25 is the link between the 2 switches I'm testing with; the stack master and a member switch; I only want tagged traffic between the switches, no untagged frames. show stacking on the master shows all members as "UP" but I can not telnet any of them: Telnet failed: Connection timed out. All switches have manually assigned (static) IP addresses on VLAN 42, and all exist in the same /25 subnet, as does my desktop. I can telnet the switches directly from my desktop to the individual switch IP addresses, just not from the master switch. Do I need to reboot the switches to have the primary-vlan change take effect? Or is there something else I'm missing?

• Heartbeat/DRBD failover didn't work as expected. How do I make the failover more robust?

  - by Quinn Murphy

  I had a scenario where a DRBD-heartbeat set up had a failed node but did not failover. What happened was the primary node had locked up, but didn't go down directly (it was inaccessible via ssh or with the nfs mount, but it could be pinged). The desired behavior would have been to detect this and failover to the secondary node, but it appears that since the primary didn't go full down (there is a dedicated network connection from server to server), heartbeat's detection mechanism didn't pick up on that and therefore didn't failover. Has anyone seen this? Is there something that I need to configure to have more robust cluster failover? DRBD seems to otherwise work fine (had to resync when I rebooted the old primary), but without good failover, it's use is limited. heartbeat 3.0.4 drbd84 RHEL 6.1 We are not using Pacemaker nfs03 is the primary server in this setup, and nfs01 is the secondary. ha.cf # Hearbeat Logging logfacility daemon udpport 694 ucast eth0 192.168.10.47 ucast eth0 192.168.10.42 # Cluster members node nfs01.openair.com node nfs03.openair.com # Hearbeat communication timing. # Sets the triggers and pulse time for swapping over. keepalive 1 warntime 10 deadtime 30 initdead 120 #fail back automatically auto_failback on and here is the haresources file: nfs03.openair.com IPaddr::192.168.10.50/255.255.255.0/eth0 drbddisk::data Filesystem::/dev/drbd0::/data::ext4 nfs nfslock

• How do I push my initial snapshot to a subscriber server in SQL Server 2000?

  - by Kev

  I'm configuring Transactional Replication using the Push model. The scenario is: The SQL Servers: SQL01 (publisher) and SQL02 (subscriber) - both running SQL 2000 SP4. Both servers are standalone (i.e. not domain members) Both servers have their FQDN and NETBIOS names in their HOSTS files I've managed to configure SQL01 to publish my database and configured a Push subscription for SQL02 using the Push New Subscription wizard and set the Distribution Agent to update the subscription continuously. On the Push Subscription wizard "Initialise Subscription" page I've selected "Yes, initialise the schema and data" and ticked the "Start the Snapshot Agent to begin the initialisation process immediately" option. All the required services are running (SQL Agent). When I complete the wizard and browse the Replication - Publications folder I can see my publication (blue book with arrow). The publication shows the Push subscription and its status is Pending. If I look in the c:\Program Files\Microsoft SQL Server\Mssql\Repldata folder I see a number of T-SQL scripts for each table e.g. Products.bcp, Products.sch, Products.idx. What should happen now? Should my replicated database now (magically) appear on the subscription server?

• Smart card driven membership and door entry system

  - by Rob G

  I'm looking at putting in a smart card driven system at my local sports club (which doesn't have oodles of money), and since they're willing to pay for hardware, and I'm willing to do the technical setup, I was wondering if anyone had any experience in setting something like this up. Writing any software needed is not the problem, I've pretty much got that covered with various open source projects out there and custom code I'll write, but it's more the hardware side I'm not too sure about and I'm looking for advice from people out there. I'm sure there are numerous complications, but on the surface it looks fairly simple. I'd basically like to enable members to swipe/touch a smart card at the door to gain entry to the club, walk up to a touch screen PC and swipe/touch a card reader there to "login" to the system I create, which will allow them to book club facilities etc. I may even want that same card to then activate things like lights or music when they enter the room they've booked. Pretty Eutopian I know, but still, we'd like to get as close as we can. As I said, the software shouldn't be a problem, and on the hardware side, so far I'm looking at: All in one touch screen PC running Windows 7 or Ubuntu USB card reader (not sure which one to buy) Smart Cards (again, never bought these before) Door/lighting hardware that could be triggered (not sure here either) If anyone has any advice on implementing something like this - especially the items I'm not sure about above, and of course anything I've missed out that's crucial, I'd be most grateful. Recommended hardware that you've used for something like this would be fantastic!
