• CMS/Wiki to use for a HTML5 video site

  - by Clinton Blackmore

  Greetings. I want to put up a website with instructive screencasts, and allow for people to add comments to them. I would like use the Video for Everybody technique, partly because I dislike Flash and because it helps in a small way to move the web forward [while being backwards compatable]. I recognize that HTML5 is still in draft, and that support for it varies. I do have some hosting space, and can run Perl, PHP, and Ruby on Rails applications, with a MySQL backend. I should mention that part of my working job involves running some web servers, and that I am a programmer by training (with only a limited familiarity with Perl and PHP, and none with Ruby). I should mention why I don't particularly want to go with a video hosting site (like YouTube or Vimeo): Flash Video Resolution and Quality [I'd like to put up 800x600 videos] Videos promote a club that is not stricly non-profit [ie. may fall afoul of Terms of Service] I'm already paying for web hosting, and free video hosting comes with time and bandwidth limits I don't want there to be two locations where you can comment on the video Now, having said all that, I'd be quite comfortable putting up my own HTML pages, except: that's so web 1.0! :) [ie. it does not allow for comments] I also want to do some blogging and possibly put up a wiki; the site will not be entirely screencasts So, can anyone recommend a CMS (or Wiki, or similar application) that I can customise for this purpose?

• Windows XP laptop doesn't appear in WSUS All computers list

  - by George

  I have this one laptop that doesn't appear in WSUS all computers list. We have about 23-25 PCs/laptops/servers in the network, all, but one are listed in WSUS. This is what I have done so far: 1) Changing Updates on local PC: Go to your Windows XP client and start a new Microsoft Management Console (MMC). At Start, Run, type MMC. Use Ctrl+M to add a new snap-in. Click Add, and then add the Group Policy Object Editor for the Local Computer. Click Close, and then click OK. Expand the Local Computer Policy. Under Computer Configuration, go to Administrative Templates, Windows Components, Windows Update. In the right-hand pane, double-click Specify intranet Microsoft update service location. Configure the settings to reflect my WSUS server. Click OK and then close the MMC without saving it. executed wuauclt.exe /detectnow 2) Edited registry key to be pushed to the PCs using GPO [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate] "WUServer"=http://wsusserver "TargetGroupEnabled"=dword:00000001 "TargetGroup"="WINXP" "WUStatusServer"=http://wsuswerver 3) executed wuauclt /resetauthorization /detectnow 4)Synchronised and refreshed the group I am running out of ideas here. The client is running Windows XP pro, WSUS version is 3.0 and is running on Windows 2008 R2 64-bit. Please, help! Thanks! EDIT 13.IX.2012 @ 15.40 I should have also mentioned that we do have a Windows Update GPO for workstations group and that laptop is a part of that group.

• Office 365 - Outlook shows Global Address List clicking "Rooms" during a meeting request

  - by TheCleaner

  This appears to be a "known" issue, but apparently no fix for it. However, I've been impressed before at the tenacity of the experts here to figure out an answer/fix. ISSUE When booking a New Meeting in Outlook (2013 or 2010) and choosing the Rooms button: The default list that opens is the Offline Global Address List: Which means a user has to change from the Offline Global Address List to the All Rooms list as shown here in order to easily pick from the list of actual rooms/resources: This isn't the default however for On-Premise Exchange servers. They default "correctly" to the All Rooms list when you click the Rooms button in the meeting request. While the option of using the Room Finder is there and does work, users have to know to click the Room Finder choice and it doesn't fix the actual root issue here. MY RESEARCH A few links I've found: http://community.office365.com/en-us/forums/158/t/41013.aspx http://community.office365.com/en-us/forums/148/p/24139/113954.aspx http://community.office365.com/en-us/forums/172/t/58824.aspx It was suggested that it might be that the "msExchResourceAddressLists attribute has incorrect value set". I checked my config by running: Get-OrganizationConfig | Select-Object ResourceAddressLists and the output was what it should be: ResourceAddressLists -------------------- {\All Rooms} QUESTION Does anyone have a fix that will make the All Rooms list be the default list when clicking the Rooms button in Outlook when using Office 365 / Exchange Online?

• Some URLs fail to load on Windows web portal

  - by jpolache

  I’m working in a large data center and have been assigned to troubleshoot and issue with a windows (IIS) web server that acts as a portal for a customer of the data center. This portal server is on a DMZ at the local data center. I don’t have access to the portal desktop and am relying on an off-site administrator to work with me to do testing and report the condition of the portal. He tells me there are no software firewalls or other filtering configured. While most of the remote web pages work fine, several of the URSs the portal is suppose to serve up fail to load. I had wireshark installed on the portal system and had a capture taken of one of the failures. I used IE to access one of the remote web servers at issue. I could see the TCP SYN-ACK coming back from the remote server, but after several HTTP GETs fail to get a response the portal server sends a reset. The webmaster of the remote web server assures me that no sites are being blocked. I had a capture taken outside the local firewall, so there should be no issue there. Another tech set up a laptop and used the IP address of the portal (we took the portal off-line for the test). The laptop loads the URL as expected. I tried having Firefox loaded to make sure that the HTTP GET was not mal-formed. Same failure as with IE. So, it seems it is not the remote web server or the network, because there was no problem with the laptop. At this point, I’m not sure what other questions to ask or tests to do.

• IPSec for LAN traffic: Basic considerations?

  - by chris_l

  This is a follow-up to my Encrypting absolutely everything... question. Important: This is not about the more usual IPSec setup, where you want to encrypt traffic between two LANs. My basic goal is to encrypt all traffic within a small company's LAN. One solution could be IPSec. I have just started to learn about IPSec, and before I decide on using it and dive in more deeply, I'd like to get an overview of how this could look like. Is there good cross-platform support? It must work on Linux, MacOS X and Windows clients, Linux servers, and it shouldn't require expensive network hardware. Can I enable IPSec for an entire machine (so there can be no other traffic incoming/outgoing), or for a network interface, or is it determined by firewall settings for individual ports/...? Can I easily ban non-IPSec IP packets? And also "Mallory's evil" IPSec traffic that is signed by some key, but not ours? My ideal conception is to make it impossible to have any such IP traffic on the LAN. For LAN-internal traffic: I would choose "ESP with authentication (no AH)", AES-256, in "Transport mode". Is this a reasonable decision? For LAN-Internet traffic: How would it work with the internet gateway? Would I use "Tunnel mode" to create an IPSec tunnel from each machine to the gateway? Or could I also use "Transport mode" to the gateway? The reason I ask is, that the gateway would have to be able to decrypt packages coming from the LAN, so it will need the keys to do that. Is that possible, if the destination address isn't the gateway's address? Or would I have to use a proxy in this case? Is there anything else I should consider? I really just need a quick overview of these things, not very detailed instructions.

• CIFS mounted drive setting "stick-bit" on all files, cannot change permissions or modify files

  - by mattmcmanus

  I have a folder mounted on an Ubuntu 8.10 sever through cifs that I simply cannot change the permissions on once mounted. Here is a breakdown of what's going on: All files within the mounted folder automatically have their permissions set to -rwxrwSrwx regardless of whether the file is create on the windows server or on the linux machine. I have the same directory mounted on two other linux servers (both running 9.10 instead of 8.10) with no problems at all. They all are using the same fstab options and the same credentials. //server/folder /media/backups cifs credentials=/etc/samba/.arcadia_cred,noexec,noserverino 0 0 I've I run a chmod command a million different ways, all of which report successfully changing the permissions. However it doesn't. The issue began after I updated from 8.04 to 8.10 Any idea why this may be happening on one machine? Since it started after an upgrade I'm not sure what is the bes thing to do. Any help you could give would great! None of my automated backup scripts are working because of this!

• Authenticated User Impersonation in Classic ASP under IIS7

  - by user52663

  I've recently moved one of our servers from Server 2003 and IIS6 to Server 2008 R2 and IIS7 (technically IIS7.5 I suppose). In doing so I am transitioning a small account management tool written in classic ASP and have run into a problem with user impersonation. Extensive searching hasn't been much help so far. Under IIS6, the site was configured to impersonate the logged-in user. Thus, if a domain admin logged in, he was able to run commands to create user directories, adjust permissions, etc. Using Procmon you can see the processes executing as that user. This worked fine. However, with the same code under IIS7, I am unable to get this behavior. I have enabled Basic Authentication, disabled Anonymous Auth, enabled impersonation and have changed the app pool to classic instead of integrated pipelining. Everything seems to be configured correctly, however, all the processes launched by the classic ASP site continue to run as the default AppPool identity and not the logged-in user. If it matters, programs are being launched with code such as: set Wsh = Server.CreateObject("WScript.Shell") Wsh.Run("cmd.exe /C mkdir D:\users\foo") Monitoring via Procmon shows cmd.exe being run as either "Classic .NET AppPool" or "DefaultAppPool" depending on the pipeline mode. Any suggestions on how to get the classic ASP site to impersonate and execute as the authenticated user would be great. Thanks!

• MySQL encoding problem after site move

  - by Quan Zhou

  Guys, I need your help. Since last month my friend has lost his database on Dreamhost, he decided to move his wordpress based blog site (written in Chinese) to my server. He's using a wp-plugin called wp-db-backup to perform regular db backups. And the servers backgrounds are: Dreamhost: Linux 2.6.31.5-modsign-aufs2-grsec-2-opt mysql Ver 14.12 Distrib 5.0.16, for pc-linux-gnu (i386) using readline 5.0 apache2 unknown version My Server: Linux li159-46 2.6.32.12-x86_64-linode12 mysql Ver 14.14 Distrib 5.1.45, for debian-linux-gnu (x86_64) using readline 6.1 nginx 0.8.36 His site's encoding was UTF-8 in both wp-config and db. I imported his db backup file in UTF-8 by default, then I sync'd files using rsync from dreamhost, then I just changed the db address and nothing more. But when I take first look at the "new" site, it was full of unreadable characters, I met this problem before, I changed charset options in browser but none of them can make it displayed properly. Then I converted his db to GB18030, it works with only if browser set charset to GB18030 either GBK, but by default they recognize the charset as UTF-8. I tried to edit the headers but it doesn't work. What could I do now? Thx~~

• Network Load Balancing, intermittent port problem

  - by Jimmy Chandra

  Trying to troubleshoot an intermittent problem. I think it might be related to an NLB issue. We are using Windows Network Load Balancing to balance load for our multiserver SharePoint front ends. Say... Web Front End 1 IP is 192.168.1.100 and Web Front End 2 IP is 192.168.1.101, the NLB is setup to load balance both WFE servers on any incoming traffic to the IP 192.168.1.200. Sometimes we got an intermittent issue where when we try to access the SharePoint site using 192.168.1.200:8080 (say the site is set up to run on port 8080) from a remote client, it will display page not found. Pinging the 192.168.1.200 will give responses, but when trying to telnet to 192.168.1.200:8080 it just won't connect. However, browsing the SharePoint site directly on individual WFE (192.168.1.100 and 192.168.1.101) show no problem whatsoever. My guess also (we didn't get a chance to try it yet, but I think it should work), if I try connecting remotely to individual server, it will respond just fine. But any attempt on trying to connect using the virtual IP (192.168.1.200) will fail miserably. Funny thing is, after a while it will return back to normal. Anyone had similar experience with this type of problem while implementing NLB before? We are doing this in a virtual environment.

• ntpd on Fedora Core 6 with high negative time reset values

  - by Mark White

  The basic problem is we have a FC6 server instance running on a virtual machine, and the system time seems to have been slowly varying until it is now causing a problem. The server runs 24/7 and has been up for 155 days. It has been changed to show GMT, and reports the time as (example) 00:15:15 GMT whereas the actual time is 00:00:00 GMT. This is an offset of 915 seconds. selinux has been changed to 'setenforce 0' for testing and I am running as root. I stop the ntpd service and change the time in System|Administration|Date & Time. The time still shows the same with 'date' in bash. There are no error logs. I change the date with 'date --set' in bash. The response confirms the changed date. I run 'date' and the incorrect date is shown. There are no error logs. I start the ntpd service and /var/log/messages shows success with 'time reset -915.720139s'. The date remains unchanged. ntpq -p shows three three time servers all have offsets of around -915 seconds. I stop ntpd service and try 'ntpd -gqx' and get the same result as above - success, but a large negative time reset. I've tried varying combinations of the above, and a few more settings in System|Administration|Date & Time - no change. I just need to reset the system time to GMT. No offset. But I can't wait for ntpd to slew the time over the next few weeks. Any advice is welcome, cheers! Surely this shouldn't be this difficult... Mark...

• How can adding a server to a domain cause Remote Desktop to stop working?

  - by Adrian Grigore

  I have two dedicated with Windows 2008 R2 servers which I am using for Web hosting. One Server A is a domain controller, Server B should simply be added to the domain controlled by Server A. So I RDP'd into Server B and changed the system settings so that Server B is part of that domain. I entered my domain admin credentials, was welcomed to the domain and asked to reboot the server. So far everything seemed to work smoothly After rebooting, I could not open an RDP connection to Server B anymore: Remote Desktop can’t connect to the remote computer for one of these reasons: 1) Remote access to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network Make sure the remote computer is turned on and connected to the network, and that remote access is enabled. I restored an older backup of Server B and switched off the firewall before adding the server to my domain. But the problem reoccurred just the same. What could be the reason for this? The domain is brandnew and I did not change any of the default settings. Could this be some kind of domain-wide default policy that shuts down RDP on any domain clients? Or perhaps it has to do with the fact that Server B is virtual? Thanks for your help, Adrian

• Cisco Pix 515 ip addressing

  - by Rickard

  I have just gotten my hands on a Cisco Pix 515 (not 515E) with 3 interfaces, and are just about to start some labs. In my lab, I am using a real life scenario from an actual setup at work. As I have no access to the device at work, I am simply trying to replicate the scenario by trial and error. At work, we are given two IP addresses from the provider, which is 1-to-1 nated addresses. The addresses we are allowed to use are: 10.131.35.4-5/29 Now, we have 3 servers on a DMZ, 192.168.2.2-4/24 and 17 client computers on 192.168.1.100-117/24 aswell as some static addressed devices on 192.168.1.8-18/27 My question is, how would I best set up so that the machines on the DMZ get's translated to 10.131.35.4 and the machines on 192.168.1.* will be translated to 10.131.35.5 I don't expect or want anyone to give me a fully functional config, I may learn from it, but I'd prefer to just have some advices or maybe a guide on how to set it up. I hope someone can shed some light over my situation, have been looking through google but I guess I don't the searchwords I'm using isn't too good as I can't find any good clues. THank you very much! PS. Maybe I should add, I am not unfamiliar with the Cisco CLI, as I prefer using that before any gui's. So not really looking for any solutions for the ASDM. DS.

• Hubs/switches taking out switches?

  - by Bart Silverstrim

  Here's the issue...we have a network with a lot of Cisco switches. Someone plugged in a hub on the network, and then we started seeing "weird" behavior; errors in communication between clients and servers, or network timeouts, dropping network connections, etc. It seemed that somehow that hub (or SOHO switch) was particularly freaking out our Cisco 3700 series switches. Disconnect that hub or netgear-type SOHO switch and things settled down again. We're in the process of trying to get a centralized logging server for SNMP and management, etc., to see if we can trap errors or narrow down when someone does this sort of thing without our knowledge because things seem to work, for the most part, without issue, we just get freaky oddball incidents on particular switches that don't seem to have any explanation until we find out someone decided to take matters into their own hands to expand available ports in their room. Without getting into procedure changes or locking down ports or "in our organization they'd be fired" answers, can someone explain why adding a small switch or hub, not necessarily a SOHO router (even a dumb hub apparently caused the 3700's to freak out) sending DHCP request out, will cause issues? The boss said it's because the Cisco's are getting confused because that rogue hub/switch is bridging multiple MAC's/IP's into one port on the Cisco switches and they just choke on that, but I thought their routing tables should be able to handle multiple machines coming into the port. Anyone see that behavior before and have a clearer explanation of what's happening? I'd like to know for future troubleshooting and better understanding that just waving my hand and saying "you just can't".

• Apache ProxyPass with SSL

• Will adding a SSD cache device to my ZFS storage improve performance?

  The server has 4GB of RAM and my zpool is made up of 15.5k SAS drives arranged like this: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c0t2d0 ONLINE 0 0 0 c0t3d0 ONLINE 0 0 0 c0t4d0 ONLINE 0 0 0 c0t5d0 ONLINE 0 0 0 c0t6d0 ONLINE 0 0 0 c0t7d0 ONLINE 0 0 0 c0t8d0 ONLINE 0 0 0 raidz1-1 ONLINE 0 0 0 c0t10d0 ONLINE 0 0 0 c0t11d0 ONLINE 0 0 0 c0t12d0 ONLINE 0 0 0 c0t13d0 ONLINE 0 0 0 c0t14d0 ONLINE 0 0 0 spares c0t9d0 AVAIL c0t1d0 AVAIL The primary use is as an NFS store for a couple VMWare ESXi servers. I can't do any "true" benchmarks because this is a production system (no budget for test systems), but using dd and bonnie++ I can't get more than ~40-50MB/s writes and ~70-90MB/s reads. It seems I should be able to do much better, but I'm not sure where to optimize. Based on what I've read, I think dropping in a OCZ Vertex 2 Pro SSD as my L2ARC is going to be the best bang-for-the-buck to improve througput. Is there something else I should be looking into to help performance? If not... How do I know how big a cache device I need? Am I safe with only a single SSD as my cache device?

• Windows 7 - Windwos XP - sharing - why isn't working?

  - by durumdara

  Hi! This is seems to be "hardware" and not "software" / "programming" question, but I need to use this share in my programs, so it is "close to programming". We had an XP based wireless network. The server is XP Professional, the clients are XP Home (Notebooks). This was working well with folder sharing (with user rights, not simple share). Then we replaced the one of the notebook with Win7/X64 notebook. First time this can reach the server, and the another client too. Later I went to another sites, and connect to another servers, another networks. And then, when I return to this network, I saw that I cannot connect to this server. Nothing of resources I see, and when try to dbl click on this computer, I got login window, where I can write anything, never I can login... The interesting part, that: Another XP home can see the server, can login as quest, or with other user. The server can see the XP home notebook. The Win7 can see the notebook's shared folders, and XP home can see the Win7 shared folders. The server can see the Win7 folders, BUT: the Win7 cannot see the server folders. Cannot see the resources too... The Win7 is in "work networking group", the group name is not mshome. I tried everything on the server, I tried to remove MS client, restore it with simple sharing, set guest password, etc., but I lost the possibilities to access this server from Win7. Does anyone have any idea what I need to see, what I need to set to access these resource - to use them in my programs? Thanks for every info, link: dd

• Load Sharing Regarding Large Websites

  - by JHarley1

  Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

• Haproxy not properly passing on X-Forwarded-For header

  - by JesseP

  I have backend web servers that receive requests by way of haproxy-nginx-fastcgi. The web app used to see multiple ip's coming through in the X-Forwarded-For header, chained together with commas (most original IP on the left). At some point in the recent past (just noticed, so not sure what caused it) something changed, and now I'm only seeing a single IP passed in the header to my web application. I've tried with haproxy 1.4.21 and 1.4.22 (recent upgrade) with the same behavior. Haproxy has the forwardfor header set: option forwardfor Nginx fastcgi_params config defines this header to be passed to the app: fastcgi_param HTTP_X_FORWARDED_FOR $http_x_forwarded_for; Anyone have any ideas on what might be going wrong here? EDIT: I just started logging the $http_x_forwarded_for variable in nginx logs, and nginx is only ever seeing a single IP, which shouldn't ever be the case, as we should always see our haproxy ip added in there, right? So, issue must either be in nginx handling of the variable coming in, or haproxy not building it properly. I'll keep digging... EDIT #2: I enabled request and response header logging in HAProxy, and it is not spitting anything out for X-Forwarded-For, which seems very odd: Oct 10 10:49:01 newark-lb1 haproxy[19989]: 66.87.95.74:47497 [10/Oct/2012:10:49:01.467] http service/newark2 0/0/0/16/40 301 574 - - ---- 4/4/3/0/0 0/0 {} {} "GET /2zi HTTP/1.1" O Here are the options i set for this in my frontend: mode http option httplog capture request header X-Forwarded-For len 25 capture response header X-Forwarded-For len 25 option httpclose option forwardfor EDIT #3: It really seems like haproxy is munging the header and just passing on a single one to the backend. This is fairly impacting to our production service, so if anyone has an ideas it would be greatly appreciated. I'm stumped... :(

• Wrong Outlook anywhere settings

  - by Ken Guru

  Hey all I wanted to enable NTLM authentication on OutlookAnywhere, and after doing the command Set-OutlookAnywhere -IISAuthenticationMethods Basic,NTLM, my settings got changed. This is a dump before I run the command: [PS] C:\Windows\system32Get-OutlookAnywhere ServerName : EXCAS01 SSLOffloading : False ExternalHostname : ClientAuthenticationMethod : Basic IISAuthenticationMethods : {Basic} MetabasePath : IIS:///W3SVC/1/ROOT/Rpc Path : C:\Windows\System32\RpcProxy Server : EXCAS01 AdminDisplayName : ExchangeVersion : 0.1 (8.0.535.0) Name : Rpc (Default Web Site) DistinguishedName : CN=Rpc (Default Web Site),CN=HTTP,CN=Protocols,CN= EXCAS01,CN=Servers,CN=Exchange Administrative Grou p (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=Fi rst Organization,CN=Microsoft Exchange,CN=Services ,CN=Configuration,DC=asp,DC=ssc,DC=no Identity : EXCAS01\Rpc (Default Web Site) Guid : 289b4865-caf1-4412-95ee-6fb0dff55e8b ObjectCategory : asp.ssc.no/Configuration/Schema/ms-Exch-Rpc-Http-V irtual-Directory ObjectClass : {top, msExchVirtualDirectory, msExchRpcHttpVirtual Directory} WhenChanged : 05.01.2011 16:59:55 WhenCreated : 27.11.2009 11:20:12 OriginatingServer : IsValid : True Noticde the settings for "Name", "DistinguishedName", and "Identity". After I run the command, I ended up with this: [PS] C:\Windows\system32Get-OutlookAnywhere ServerName : EXCAS01 SSLOffloading : False ExternalHostname : ClientAuthenticationMethod : Basic IISAuthenticationMethods : {Basic, Ntlm} MetabasePath : IIS:///W3SVC/1/ROOT/Rpc Path : C:\Windows\System32\RpcProxy Server : EXCAS01 AdminDisplayName : ExchangeVersion : 0.1 (8.0.535.0) Name : EXCAS01 DistinguishedName : CN=EXCAS01,CN=HTTP,CN=Protocols,CN=EXCAS01,CN=Serv ers,CN=Exchange Administrative Group (FYDIBOHF23SP DLT),CN=Administrative Groups,CN=First Organizatio n,CN=Microsoft Exchange,CN=Services,CN=Configurati on,DC=asp,DC=ssc,DC=no Identity : EXCAS01\EXCAS01 Guid : 289b4865-caf1-4412-95ee-6fb0dff55e8b ObjectCategory : asp.ssc.no/Configuration/Schema/ms-Exch-Rpc-Http-V irtual-Directory ObjectClass : {top, msExchVirtualDirectory, msExchRpcHttpVirtual Directory} WhenChanged : 06.01.2011 09:43:50 WhenCreated : 27.11.2009 11:20:12 OriginatingServer : ASP-DC-2. IsValid : True Now, the "Name", "DistinguishedName" and "Identity" has changed, and when I try to change it back by running "Set-OutlookAnywhere -Identity "EXCAS01\Rpc (Default Web Site)", I get the following error: [PS] C:\Windows\system32Set-OutlookAnywhere -Identity "EXCAS01\Rpc (Default Web Site)" Set-OutlookAnywhere : The operation could not be performed because object 'EXCA S01\Rpc (Default Web Site)' could not be found on domain controller 'ASP-DC-2.'. Remember, the RPC over HTTP works fine with Basic authentication (even with the wrong settings), but NTLM still doesnt work. How do I change back the settings?

• Robocopy failure with Windows Server 2008 Scheduled Task

  - by CC

  So I have a batch script for robocopy. Running this from the command line does exactly what I want. robocopy "D:\SQL Backup" \\server1\Backup$\daily /mir /s /copyall /log:\\lmcrfs4g\NavBackup$\robocopyLog.txt /np Then I create a Scheduled Task in Windows Server 2008. If I set up the task to use my Domain Admin account, great. But I'm trying to get it to run as a separate domain account for Scheduled Tasks. If I use that account, folders get created, but files aren't copied. I get the following error: 2011/02/17 15:41:48 ERROR 1307 (0x0000051B) Copying NTFS Security to Destination Directory D:\SQL Backup\folder\ This security ID may not be assigned as the owner of this object. I've verified my domain\Scheduled Tasks account has Full Control NTFS permissions on both the source and destination, and the Full Control Sharing on my hidden \server1\backup$ share. Just for giggles, I've tried adding the domain account to the local Administrators group on both servers. This works fine, but that seems like a lot of privileges just to copy files. Any ideas on what I'm missing?

• Passing PATH through sudo

  - by whitequark

  In short: how to make sudo not to flush PATH everytime? I have some websites deployed on my server (Debian testing) written with Ruby on Rails. I use Mongrel+Nginx to host them, but there is one problem that comes when I need to restart Mongrel (e.g. after making some changes). All sites are checked in VCS (git, but it is not important) and have owner and group set to my user, whereas Mongrel runs under the, huh, mongrel user that is severely restricted in it's rights. So Mongrel must be started under root (it can automatically change UID) or mongrel. To manage mongrel I use mongrel_cluster gem because it allows starting or stopping any amount of Mongrel servers with just one command. But it needs the directory /var/lib/gems/1.8/bin to be in PATH: this is not enough to start it with absolute path. Modifying PATH in root .bashrc changed nothing, tweaking sudo's env_reset and keepenv didn't either. So the question: how to add a directory to PATH or keep user's PATH in sudo?

• Where do I define a group policy that will set a users desktop background color to green the first time they log in?

  - by Tyler

  Servers: W2k8 R2 x64 Desktops: Win7 Pro x64 Our current group policy uses a custom ADM file to define certain properties of the desktop (Background Image (centered), Background Color is green (00 74 00)). This policy works for us, but the down-side is that policies defined in our custom ADM are only applied after a GPUpdate /Force is applied. We would like these desktop theme settings to be applied the first time the user logs onto the computer. I've been working on a new policy that forces the computer to wait for the network when the user logs on to handle folder redirection. The reason for writing the new policy was to resolve the issue that a user needs to run GPupdate /Force the first time they log in, so it doesn't make sense for me to implement the new policy if there is still something that requires GPUpdate /Force to get the user in the state that we want them. I've moved the setting for background image out into Admin Templates- Desktop- Desktop- "Desktop Wallpaper" so this is now being set properly when the user first logs in. Now I'm left with a black background until I force a group policy update. I have tried to play around with setting a default "Theme" and had limited success; this was not reliable enough to call a solution. I suppose I could set the background color with a script? Any thoughts? It feels like I'm missing something obvious, or that this should be much easier than it is.

• sudo or acl or setuid/setgid ?

  - by Xavier Maillard

  Hi, for a reason I do not really understand, everyone wants sudo for all and everything. At work we even have as many entries as there are way to read a logfile (head/tail/cat/more, ...). I think, sudo is defeating here. I'd rather use a mix of setgid/setuid directories and add ACL here and there but I really need to know what are the best practices before starting up. Our servers have %admin, %production, %dba, %users -i.e many groups and many users. Each service (mysql, apache, ...) has its own way to install privileges but members of the %production group must be able to consult configuration file or even log files. There is still the solution to add them into the right groups (mysql...) and set the good permission. But I do not want to usermod all users, I do not want to modify standards permissions since it could change after each upgrade. On the other hand, setting acls and/or mixing setuid/setgid on directories is something I could easily do without "defacing" the standard distribution. What do you think about this ? Taking the mysql example, that would look like this: setfacl d:g:production:rx,d:other::---,g:production:rx,other::--- /var/log/mysql /etc/mysql Do you think this is good practise or should I definetely usermod -G mysql and play with standard permissions system ? Thank you
