• How to bypass vpn talking to VMWare Guest?

  - by marc esher

  Greetings. Network/VPN n00b question here. I'm running VMWare Workstation with a Guest Windows 2003 Server. It has SQL Server 2000 installed. The sole purpose for this Guest is to house SQL Server... it needn't have internet access or access to any other resources on the network other than the host. When launch Check Point VPN software, the host routes through the company network before it connects to the guest ... i.e. it's no longer a direct connection. I assume this is just how things are supposed to work. However, what's happening is that the connection between my host and the SQL Server instance on the guest intermittently drops. It's not consistent, and some databases on the server will be responsive while others aren't. It appears that the databases with the most traffic on the guest (the ones I'm hitting with load tests) are the ones that become intermittently unresponsive. This problem only manifests when VPN is on; when it's off, I can pound away on this database with no troubles. Thanks for any advice!

• Google bots are severely affecting site performance

  - by Lynn

  I have an aggregate site on a linux server that pulls in feeds from a universe of about 2,000 blogs. It's in Wordpress 3.4.2 and I have a cron job that is staggered to run five times an hour on another server to pull in the stories and then publish them to the front page of this site. This is so I didn't put too much pressure all on one server. However, the Google bots, which visit a few times every hour bring the server to its knees in the morning and evenings when there is an increase in traffic on the site. The bots have something like 30,000 links to follow at this point. How do I throttle the bots to simply grab the new stories off the front page and stop there? EDIT- Details of my server configuration: The way we have this set up is the server that handles all the publishing is an unmanaged instance via AWS. It mounts the NFS server and connects to the RDS to update content, etc. You get to this publishing instance via a plugin that detects the wp-admin link and then redirects you into there. The front end app server also mounts the NFS and requests data from the RDS. It is the only one that has the WP Super Cache on it.... The OS is Ubuntu on the App server and the NFS runs CentOs. The front end is Nginx and the publishing server is Apache.

• Safemode Startup Issues on Vista 64 Bit

  - by GnrlBzik

  Before i ask the question, let me point out that this is not a hardware issue. I have a clean install of vista on another hd that runs on same hardware, i am pretty sure its a corruption of a drive or a file, i presume it might be video driver. When windows wont start via normal boot i just get black screen after initial load up of os, so i boot into savemode, I end up having black screen with a mouse pointer visible, after initial load of os. The shut down button is responsive. Of course, I can install clean copy of os, and prior to that can retrieve all other files that i need by accessing hd itself, i can restore my pc from my external back up as well. Although i have all these options, i was wondering if there anything else i can do that can help me fix this issue. In save mode, it looks like I am capable of logging in after initial load of os, even though i cant see the process it self, i do see the mouse pointer. By visual memory i navigated to password field, and entered my password, hit enter, I get the loading mouse pointer, nothing really changes, same black screen and mouse pointer, but when i tried to access task manager for a second i got a safemode watermark at all four corners. Any help would be appriciated. Thank you in advance.

• Sendmail stat=Sent

  - by user44774

  Guys, I am trying to figure out why sendmail is saying that it sends out an email but I actually never get it. This is from the logs when the email is being sent out: I have replaced the email address with some fake address and I have also replaced the name of the server with a fake hostname. The most significant point of this information from the logs is that it shows that the "Message was accepted for delivery". Do you guys have any suggestions as to why it seems like the message goes out but I never get the actual email?

• Mechanism behind user forwarding in ScriptAliasMatch

  - by jolivier

  I am following this tutorial to setup gitolite and at some point the following ScriptAliasMatch is used: ScriptAliasMatch \ "(?x)^/(.*/(HEAD | \ info/refs | \ objects/(info/[^/]+ | \ [0-9a-f]{2}/[0-9a-f]{38} | \ pack/pack-[0-9a-f]{40}\.(pack|idx)) | \ git-(upload|receive)-pack))$" \ /var/www/bin/gitolite-suexec-wrapper.sh/$1 And the target script starts with USER=$1 So I am guessing this is used to forward the user name from apache to the suexec script (which indeed requires it). But I cannot see how this is done. The ScriptAliasMatch documentation makes me think that the /$1 will be replaced by the first matching group of the regexp before it. For me it captures from (?x)^/(.* to ))$ so there is nothing about a user here. My underlying problem is that USER is empty in my script so I get no authorizations in gitolite. I give my username to apache via a basic authentication: <Location /> # Crowd auth AuthType Basic AuthName "Git repositories" ... Require valid-user </Location> defined just under the previous ScriptAliasMatch. So I am really wondering how this is supposed to work and what part of the mechanism I missed so that I don't retrieve the user in my script.

• How do I upgrade Windows Server 2008 R2 Standard (OEM Key) to Enterprise (MSDN Key) using DISM?

  - by Tom Crane

  (Originally asked as After upgrading to 2008 R2 Enterprise and installing more RAM, Windows can only see 4.00 GB but now I know what the question really is...) My Dell server came preinstalled with 2008 R2 Standard. I upgraded to Enterprise to take advantage of more than 32GB RAM. This server is purely for dev and testing, so I want to use my MSDN product key for the upgrade. I originally tried to uprade using the MSDN Enterprise key, but it wouldn't have it: dism /online /Set-Edition:ServerEnterprise /ProductKey:[MSDN key] => Error DISM DISM Transmog Provider: PID=5728 Product key is keyed to [], but user requested transmog to [ServerEnterprise] - CTransmogManager::ValidateTransmogrify I tried several things, including changing the current product key to the MSDN one. Eventually I used a KMS generic key which can be found in several technet forum posts. dism /online /Set-Edition:ServerEnterprise /ProductKey:[KMS Generic Key] ... and this appeared to work. I then changed the product key again (using the control panel) to the MSDN key, thinking that was the end of the matter. Only later when tried to start up VMs did I realise I only had 4GB of usable RAM. I didn't make the connection with the licensing changes at this point and went off on a wild goose chase of BIOS settings, memory configurations and the like. Only later when I saw this... http://social.technet.microsoft.com/Forums/en/winserverTS/thread/6debc586-0977-4731-b418-ca1edb34fe8b ...did I make the connection and reapply the KMS Generic key - which gave me all the RAM back. But now I have a system that isn't properly licensed, presumably I won't be able to activate it as it is, so I've got 2 days to enjoy it. With the MSDN key applied, only 4GB RAM is usable. Is there a way round this without a) rebuilding the server from scratch with the MSDN key from the start or b) buying a retail Enterprise license

• Vista won't boot. BSOD: Page fault in nonpaged area

  - by user31576

  Here's the story: I let Windows Update do the updates it wanted to do, then rebooted the computer. The updating process was taking time so I went away. When I came back, my computer was rebooting. It got as far as the Windows logo with the laoding bar. BSOD'd. Rebooted. And I'm stuck in this loop ever since. Looked up on the net, the "Page fault in nonpaged area" seems to be linked to faulty RAM or drivers. So I ran a memory test, it found no error. When I try in safe mode (with promt) I can see a list of drivers being loaded, then I get the same BSOD. I tried to repair using the Vista DVD, it says "nothing to repair". I tried to restore to a previous state, it says "no restore point found". So, my guess is, it's got something to do with the drivers. How can I identify the one causing the BSOD? If you have any other leads, What can I do? By the way, I'm writing from this very computer, running a linux distro I installed after the BSOD loop started. So i guess it's not an hardware issue. I have backed up important data, and will format and reinstall Windows if I must. But I'd like to avoid that. Thanks in advance for any help you can give me.

• PTR and A record must match?

  - by somecallmemike

  RFC 1912 Section 2.1 states the following: Make sure your PTR and A records match. For every IP address, there should be a matching PTR record in the in-addr.arpa domain. If a host is multi-homed, (more than one IP address) make sure that all IP addresses have a corresponding PTR record (not just the first one). Failure to have matching PTR and A records can cause loss of Internet services similar to not being registered in the DNS at all. Also, PTR records must point back to a valid A record, not a alias defined by a CNAME. It is highly recommended that you use some software which automates this checking, or generate your DNS data from a database which automatically creates consistent data. This does not make any sense to me, should an ISP keep matching A records for every PTR record? It seems to me that it's only important if the IP address that the PTR record describes is hosting a service that is sensitive to DNS being mismatched (such as email hosting). In that case the forward zone would be configured under a domain name (examples follow the format 'zone - record'): domain.tld -> mail IN A 1.2.3.4 And the PTR record would be configured to match: 3.2.1.in-addr.arpa -> 4 IN PTR mail.domain.tld. Would there be any reason for the ISP to host a forward lookup for an IP address on their network like this?: ispdomain.tld -> broadband-ip-1 IN A 1.2.3.4

• Exchange 2010 CAS Removal == Broken???

  - by Doug

  Hi there, I recently upgraded to exchange 2010 and have a setup with 2 of my servers running CAS roles - EXCH01, EXCH02 EXCH02 just happens to also have a mailbox role where a lot of the users sit EXCH01 is my front facing CAS server, and is facing the net with SSL etc and incoming mail moving through it as a hub transport layer server as well. As i was trying to lean things out in my VM environment i removed the CAS role from EXCH02 and all hell broke loose. All the mail users that have a mailbox on EXCH02 had their homeMTA set to a deleted items folder in AD and so did their msExchHomeServer properties. After a complete battle i manually fixed these issues to the oldvalues, and in the mean time reinstalled CAS on EXCH02 (management was going nuts with out OUTLOOK working so i just put things back the way they were in a hurry.) I must add as a strange thing on the side, that before i reset these to point at EXCH02 i tried EXCH01 and it failed. I still want to remove the CAS role from EXCH02 as it should really not have it (error on install/planning on my part) and would have thought that this would not cause the issues it did, i assumed that the fact that there was another CAS server in the admin group all would be good. Was i wrong in my assumption? and what can i do to complete this successfully the second time round? Do i need to rehome all the mailboxes to the CAS server? is this a bug in the role uninstall?

• Apache inflate application/ with mod_filter

  - by BGT

  I need to prevent pdf objects from being gzipped. Really, this only needs to take place if the request is from the Mozilla browser (but since I can't get something as seemingly simple as no-gzip for application/pdf, I figure it's wiser to start there). From looking at the apache documentation on mod_filter, I've got the following: <Location /> FilterDeclare gzipDeflate CONTENT_SET FilterDeclare gzipInflate CONTENT_SET FilterProvider gzipDeflate deflate req=User-Agent $Mozilla/ FilterProvider gzipInflate inflate resp=Content-Type $application/ FilterChain +gzipDeflate +gzipInflate </Location> From my testing, the gzipDeflate filter is doing its job and all the pages without the Content-Type starting with application are being gzipped. But, the gzipInflate doesn't seem to be working at all. I've inspected the response in Firebug and verified that the Content-Type being sent down is application/pdf. I'll go ahead and ask a potentially stupid question though: The response's Content-Type header in its entirety read "application/pdf; charset=Windows-1252". Does that make any sort of difference or is $application/ presumably enough to catch that? Any help is greatly appreciated. One other point, the URL that returns the pdf object does not have the .pdf extension. The pdf itself is stored in an Oracle database as a blob and appended to the page when appropriate (all the urls in the system use the same baseline). This was part of an original inquiry by a helpful member at stackoverflow who pointed me towards mod_filter and suggested I post the question here.

• What is it safe to let Revo Uninstaller cleanup leftovers?

  - by msorens

  I have been a user of Revo Uninstaller (free) for sometime and find it does a very good cleanup job with typical applications. Today I wanted to clean up my machine a bit more so I proceeded to remove Visual Studio 2005 with Revo Uninstaller. The VS installer removed the app with no issues, then Revo reported about 20,000 leftover registry keys. I am used to basically just see Arpcache and Muicache... since I am not a registry expert I had no clue about most of the 20,000 listed. So I backed up the registry then let Revo remove the 20,000. It next reported about 1500 leftover files which included my Microsoft Office applications(!) that I knew it should not be touching. So I did not delete any files with Revo. Suspecting that some of the removed keys were also Office-related, I tried to open Word and Excel, both of which knew something was up, as the installer kicked in (albeit just briefly) for each of them. At this point, since I knew there were issues, I just restored the registry and I am now (seemingly) running OK. My question, then: When is it safe to trust Revo Uninstaller? As a seasoned software professional, my own answer to this would be the obvious "When the keys it reports are something you understand and know are safe to delete" but then that makes Revo of little use except to registry experts, does it not...?

• Windows: disable remote access of local drive, even by domain admin

  - by Matt

  We have a network of Windows 7 PCs that are managed as part of a domain. What we want is for the domain admin to be unable to view the PC's local drive (C:) unless he is physically at the PC. In other words, no remote desktop and no ability to use UNC. In other words, the domain admin should not be allowed to put \\user_pc\c$ in Windows Explorer and see all the files on that computer, unless he is physically present at the PC itself. Edit: to clarify some of the questions/comments that have come up. Yes, I am an admin---but a complete Windows novice. And yes, for the sake of this and my similar questions, it is fair to assume that I am working for someone who is paranoid. I understand the arguments about this being a "social problem versus a technical problem", and "you should be able to trust your admins", etc. But this is the situation in which I find myself. I'm basically new to Windows system administration, but am tasked with creating an environment that is secure by the company owner's definition---and this definition is clearly very different from what most people expect. In short, I understand that this is an unusual request. But I'm hoping there is enough expertise in the ServerFault community to point me in the right direction.

• 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.

• Terminate child processes on ctrl-c

  - by jackweirdy

  In tiny core linux, I have the following script: #!/bin/sh # ~/.X.d/freerdp.sh rdp(){ while true do xfreerdp -f [IP Address] done } rdp & It's pretty simple; when X starts up and checks the .X.d directory (as is the case in tiny core) it finds and executes this script. The script starts up freerdp and keeps a connection open to the server by restarting it whenever it closes. As you can see from the rdp & line, the function is run in the background to allow X to continue its startup routine. The problem is that whenever I cancel X with a Ctrl-Alt-Backspace the rdp process doesn't die. I'm looking for a way to kill the process as soon as X finishes, either through: A) a script, executed on X closing, which kills the process or B) by modifying the script to check the return value of the xfreerdp command. NB - if the solution does check the return value, it must only end if the command fails to open the X display. For that reason, if you could point me to a reference for xfreerdp return values I'd be grateful.

• Why do HTTP loopback connections not work on my subdomains?

  - by memeLab

  I have a shared hosting account at Jumba running Linux kernel 2.6.9-103.ELsmp (don't know if that helps) with cpanel 1.0 (RC1). I am using the WordPress plugin Backup Buddy, which requires HTTP loopback connections to monitor / complete backups. This works fine on memelab.com.au, but doesn't work at any subdomain (e.g.: staging.memelab.com.au). Is it possible to setup an A record or some such to remedy this? I'm aware of a workaround, (setting WP_ALTERNATE_CRON) but I find this unsatisfactory due to the messy URLs. BackupBuddy:_Frequent_Support_Issues#HTTP_Loopback_Connections_Disabled Here is the reply from my host: …as main domain have it's own separate DNS entry it have localhost entry which helps for looback connections where as subdomains don't have separate DNS zone, so it is not possible to create looback connections for it. I have cpanel access to the 'advanced zone editor' - is there anything tricky I can do there? maybe 127.0.0.2? (I remember reading that there were at least 8 available local IPs available on (some) Linuxes.) All the A records point to the server IP, with the exception of localhost.memelab.com.au which points to 127.0.0.1. I've just tried entering a new A record: localhost.itours.memelab.com.au pointing to 127.0.0.2. I still get the warning in Backup Buddy that loopback is not active, and Cpanel won't let me enter 127.0.0.1 (guess it doesn't work like that!) nslookup itours.memelab.com.au Server: 203.88.112.33 Address: 203.88.112.33#53 Non-authoritative answer: Name: itours.memelab.com.au Address: 117.55.224.177

• if the file changes send email about diff

  - by user62367

  I have 2 script. Script "A", Script "B". Script A is regulary watching the dhcpacks [dhcp release is configured to 2mins] in the logs, for the past 2 minutes. It writes the MAC addresses to a file [/dev/shm/dhcpacks-in-last-2min.txt] every 2 minutes. Ok, this is working, active clients are in this file. Super! Script B: On pastebin I'm trying to create a script, that watches the changes in /dev/shm/dhcpacks-in-last-2min.txt file ( every 1 sec). Ok. But: my watcher script [the pastebined][1] is not working fine - sometime it works, sometime it sends that someoneXY logged out`, but it's not true! Nothing happened, and the problem is not in the Script A. Can someone help me point out, what am I missing? How can I watch a file (in every sec), that contains only MAC addresses, and if someone doesn't get dhcpack in 2 minutes, the file /dev/shm/dhcpacks-in-last-2min.txt changes, and that clients MAC address will be gone from it, and i need to know, who was it [pastebined my script - but somethings wrong with it]. Thank you for any help..I've been pathing my script for days now.. :\

• HP Photosmart C4780 printer/scanner breaks netgear WNDR3700v3 router on connection

  - by CodeJunkie

  A few months ago, we upgraded our Netgear router's firmware. Immediately, we started having trouble connecting to the internet. Each time this problem would happen, every device in the house would stop being able to make new connections to the internet. For example, you couldn't open new pages in the browser, but if Skype was running when the problem happened, you could keep talking to people. The only solution to this problem seemed to be resetting the router to factory defaults. Eventually, we solved this problem by just downgrading the router firmware. A while later, we got a new Netgear router. Almost right away, the new router started having exactly the same problems as the old one did on current firmware. The network connection would stay active and the computer would say it had an internet connection, but you couldn't do anything online except for using Skype. We eventually figured out that this happens every time our HP printer gets onto the network. Any time the printer gets onto the wireless network, the whole network stops connecting to the internet almost completely. The only thing that will fix it at that point is to reset the router to factory specs, and unplug the printer so it can't get back onto the network. The Netgear router has the latest version of the firmware, but the printer/scanner is very old. It looks to me like this problem is probably a result of a firmware conflict between the printer and the router, but I'm not sure how to fix that problem. Here's some additional information: Printer: HP Photosmart C4780 Router: WNDR3700v3 Router firmware: V1.0.0.22_1.0.17 (Stock, up to date firmware) Why would the printer getting on the network cause the router to not be able to access the internet correctly until it was reset? What can be done to allow the printer to be on the network without breaking the network for all other devices? Edit: One other thing that happens during this internet problem is that multiple computers in the house display an "IP conflict" message repeatedly, and extremely frequently (as often as every five to ten minutes, and every time a connection to the wireless is made).

• Setting up port forwarding for web server

  - by Javier Badia

  This could belong on Super User, but I thought this place was more appropiate. I want to run Apache in my computer and want to make it available to the outside world to test a couple things. Apparently, I have to go into my router's (a TP-LINK TD 8910G) settings and forward port 80 to my PC's IP. So far so good. Thing is, since the router uses a web based interface and it's kind of stupid, it told me that since I was using port 80 for this, I should access its settings through port 8080. Maybe it can't detect requests coming from the LAN, I don't know. Point is, now neither port can't access the configuration, and I can't access Internet. Specifically, trying to access anything (including 192.168.1.1, the router's settings) through port 80 turns up a blank page (maybe if I had the server running in my computer I'd get something, but I don't want to risk trying, I had to reset the router and restore the settings), and port 8080 gives a "Can't establish connection" error in Firefox (and similar ones in other browsers). Is there a way to configure the router to not redirect requests coming from inside the network? I'm a beginner with this stuff, so please try to explain in a simple way. If this is more appropiate in Super User, I'm sorry.

• Unable to connect to FTP - Connection timeout after MLSD

  - by Afrosimon

  So here is my problem, I'm absolutely unable to connect to a FTP server, in circumstances I've never seen before. Here is the situation : I get a "Connection timed out" just after the MLSD command. I usually use Filezilla, under Ubuntu, but to make sure the problem isn't related to this particular client I tried a few others : gftp on ubuntu and winscp and freeftp on windows 7. All the same result. Also made sure to try with Active or Passive modes. Same result. At this point I would be inclined to think there is something wrong with my current network (furthermore, according to a coworker the FTP server is OK). But I did check with http://ftptest.net/ and I am able to get the directory listing (which I'm not able to through a FTP client). So in the end the last thing I didn't tried is to go on another network, solution which seems would work, but wouldn't be very practical in the long run. And thus I guess there's something wrong with my router... but what could it possibly be? Note : I did try to register and post this question on filezilla's board first... but I can't create an account with a gmail nor hotmail account. WTF?

• Why does Windows 7 have three system partitions?

  - by Ben

  I am using Windows 7, and I wanted to make a System image (using Windows 7), but Windows 7 checked three partitions as System (100 MB + C (install partition) + D (my partition for my files, all programs are installed at C)). I don't want to backup my D partition, but that is not really the point. I don't want Windows messing with my other partitions and making them system. Is there a way to limit Windows 7 just to partition C (install partition)? If there is no way to stop Windows from making other partitions system, can I at least delete the files that make partition D system? PS: All these three partitions are on one physical disk, partitions from other disks aren't treated as System. FACTS: desktop PC, no OEM partitions, I personally have installed Windows 7 (many times) on the C partition. Why is my D partition checked as System partition when I try to create a System Image (using Windows 7 Ultimate built in tool), even though Windows (and all the software) are installed on the C partition? Is there a way to make D "normal" or non-system partition? Here is a picture of how it looks like if I try to create a system image. Once again, why is D also a system partition?

• Why do I have three My Documents folders?

  - by root45

  I'm trying to fix my profile on Windows 7. Currently %USERPROFILE% points to C:\Users\myUsername My Documents is also at C:\Users\myUsername \\profileServer\profiles$\myUsername has TWO "My Documents" folders Neither of these folders contain what's in C:\Users\myUsername\My Documents Navigating to %USERPROFILE% in Windows Explorer displays two copies of everything, one local and one copy from the server. Programs use sort of a toss up between C:\Users\myUsername\My Documents or one of the two My Documents on profileServer. According to our sysadmins, My Documents is supposed to point to the profile server, but other folders should be local. How can I fix this so I have ONE copy of everything, with My Documents pointing to \\profileServer\profiles$\myUsername\Documents and everything else local? To be honest, I don't understand why this is so difficult and confusing. For example, why does Windows allow displaying two folders with the same name in the same directory? And why does inputting C:\Users\myUsername and %USERPROFILE% into Windows Explorer produce two different results? They should be identical. Some screenshots My directory on the profileServer My local user directory, C:\Users\myUsername Navigating to %USERPROFILE% in Windows Explorer Showing that %USERPROFILE% is set to a local directory

• Problem with Outlook 2010 (SMTP AUTH LOGIN)

  - by Filipe YaBa Polido

  **IGNORE THIS QUESTION - SOLVED WITH A PYTHON SCRIPT available at: http://yabahaus.blogspot.com I have to connect one customer Outlook 2010 to a remote server on which I have either no right, neither way to talk to the sysadmin. This is the thing, after installing and reviewing the logs on Wireshark: Outlook Express: HELO machine AUTH LOGIN username base64 encoded password base64 encoded mails go through. Outlook 2010: HELO machine AUTH DIGEST-MD5 response from server Outlook sends just a * AUTH LOGIN password base64 encoded So... I can send mails in the same domain, but can't send outside, it gives me a relay denied message. My point is... Why the h**l Outlook 2010 doesn't send the username AND the password?! It can never login the right way :| With other versions of Outlook it works fine, and with OE works great, it auths and allows to send mail to a different domain. I've googled and nothing worked. I'm pretty sure that I'm not alone with this one. My last resort will be to configure a local proxy/server that relays to the original one :| Any help would be appreciated. Sorry my bad english as is not my natural language. Thanks.

• Access denied to external USB disk; update access rights fails in Windows 8

  - by gerard

  I use to work with 2 laptops (Windows vista and Windows 7), my work files being on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take Windows 8. I suspect something changed with access rights, as my external disk suffered some "access denied" problem on Windows. I was prompted (by Windows 8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying disk is not ready Additionally, my external usb disk somehow was not recognized anymore. Back to Windows 7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them I could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under Windows 7, all the folder showed with a lock. Then back again to Windows 8. Same problem : access denied to my disk + no way to change access rights as it gets stuck disk is not ready". Now I am pretty sure there is some kind of bug or inconsistency in Windows 8 / Windows 7. I did 2. and 3. a few times. At some point, I also got an access denied in Windows 7. I could restore access rights to the disk to "System" (properties - security - EDIT for full control to group "system". ). But then I still get the same access right pb on Windows 8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. I upgraded Windows8 with the Windows8 updates available. Does not help.

• saving and searching encrypted mail

  - by student

  I often send and receive gpg-encrypted mail. At the moment I use thunderbird + enigmail (in linux) to do that. As far as I know there is no way in thunderbird to find all encrypted messages which bodies contain particular keywords. There also seems to be no option to save encrypted mails decrypted (so they would be searchable). However for me it is important to be able to search old encrypted mails. So my question is: Is there a way in linux to save incoming mails automatically decrypted in my inbox and save outgoing encrypted mail decrypted in the send folder? Both times adding a line to the body which remarks that the mail was encrypted. It could be another email client for linux that could to that or perhaps a solution using procmail or maildrop. For a procmail solution I guess there could be some problems with encoding (perhaps one have to use emil?) the solution should work well with german special characters in subject and body. Note that the solution should work for multipart encrypted messages (including encrypted attachments) too i.e. with everything which could thunderbird + enigmail generate. Further note that I don't want a discussion about security holes. For me it's ok if messages are stored decrypted on my harddrive (which is encrypted as a whole anyway). In doubt for a first solution it would be ok to store my private key passphrase in cleartext on my harddrive, too. The point is that the mails are encrypted on the mailserver or more generally on their "way through the net".

• Does my Oracle DBA need root access?

  - by Dr I

  I'm currently discussing with my Oracle DBA Collegue that request a root access on our production servers. I'm not so hot to let him use the root access on our production servers. He is arguing that he need it to perform some operations like restarting the server and some other obscure arguments. The point is that I'm not agree with him because I've set him a Oracle user/group and a dba group where Oracle user belong. Everything is running smoothy and without any root permissions for now. I also think that all administrative tasks like scheduled server restart and so one need to be operated by the proper administrator (The Systems administrator on our case) to avoid any kind of issues related to a misunderstanding of the infrastructure interactions. So, I need the help of both, sysadmins and Oracle DBAs to lead me on the correct direction. If my collegue really need this rights I'll give him, but I'm just basically quite affraid of that because of security and integrity concerns. I know that my collegue is really good as a Oracle DBA and he know is work very well, but I also know that I've very few cases where a software and its admin really need root access. Once again, I'm not looking for pros/cons but rather an advice on the way that I should take to deal with this situation.
