• How secure is the encryption used by Microsoft Office 2007?

  - by ericl42

  I've read various articles about Microsoft's Office 2007 encryption and from what I gather 2007 is secure using all default options due to it using AES, and 2000 and 2003 can be configured secure by changing the default algorithm to AES. I was wondering if anyone else has read any other articles or know of any specific vulnerabilities involved with how they implement the encryption. I would like to be able to tell users that they can use this to send semi-sensitive documents as long as they use AES and a strong password. Thanks for the information.

• Plesk file permissions - Apache/PHP conflicting with user accounts.

  - by hfidgen

  Hiya, I'm building a Drupal site which performs various automatic disk operations using the apache user (id=40). The problem is that the site was set up on a subdomain belonging to user ID 10001 (ie my main FTP account) so the filesystem belongs to that user ID. So I keep getting errors like this: warning: move_uploaded_file() [function.move-uploaded-file]: SAFE MODE Restriction in effect. The script whose uid is 10001 is not allowed to access /var/www/vhosts/domain.com/httpdocs/sites/default/files/images/user owned by uid 48 in /var/www/vhosts/domain.com/httpdocs/includes/file.inc on line 579. I've tried changing the apache group in httpd.conf to apache:psacln, psacln being the default group for all web users but that's not helped. The situation now is: ..../files/images/ = 777 and chown = ftplogin:psacln ..../files/images/user = 775 and chown = apache:psacln ..../files/tmp = 777 and chown = ftplogin:psacln So apparently uid 40 and 10001 both have permissions to write to any of the 3 directories involved, but still can't. Am i missing something here? Can anyone help? Thanks!

• Cannot ping ubuntu server by hostname - can only ping by IP

  - by Tone

  I have an unbuntu 9.10 server and have set the hostname to "fileserver" When I try to ping fileserver from a client machine it doesn't find it, however I can ping by the IP my router assigns it. I have tried changing the ip in /etc/hosts from this: 127.0.0.1 fileserver to this: 192.168.1.109 fileserver which is the ip being assigned. I had a previous install of this server and i had no issues with this - only difference in this install is i did not select any of the options such as LAMP, OpenSSH, etc during the install process. I can access the machine fine by ip using PuTTY. Any ideas?

• Manual Duplex for Mac (and/or Linux)

  - by chris_l

  Hi, my printers don't support automatic duplex printing. I'm looking for a solution for my Mac (BTW, also for Linux) that I've seen with most Windows printer drivers: Check "Manual duplex" in the printer screen Printer starts printing one side A dialog appears, asking me to flip the pages Printer prints the other side. One thing I can do, is "print odd pages", then reopen the dialog and "print even pages", but this is very inconvenient, especially when I only want to print a certain page range of the document (the Mac dialog forgets my previous page range every time). It gets even more inconvenient, when printing 2-up double sided, or when changing additional settings for this one printout. So is there maybe some tool, that can do this? Or maybe a "virtual printer driver" that can sit somewhere between the dialog and the actual printer driver, which manages these steps? (The Windows tool http://en.wikipedia.org/wiki/FinePrint can do something like that, but I don't need all of its features - and I need it on Mac/Linux) Thanks, Chris

• How do I handle mysql replication in EC2 using private IPs?

  - by chris

  I am trying to set up a mysql master/slave configuration in two EC2 instances. However, every time I reboot an instance, the IP address (and hostname) changes. I could assign an Elastic IP address, but would prefer to use the internal IP address. I can't be the first person to do this, but I can't seem to find a solution. There are a lot of "getting started" guides, but none of them mention how to handle changing IP addresses. So what are the best practices to manage master/slave replication in EC2?

• How to restore jump list for Windows Explorer pinned taskbar icon?

  - by Dario Solera

  I pinned Windows Explorer's icon to my taskbar months ago, and all worked fine, including jump lists. Note: I changed the default Explorer's folder using the usual trick of changing the GUID in the shortcut. Now, all of a sudden, the jump list is empty, and dropping folders on the pinned icon does not produce any effect, nor recently-opened folders show up in the list (although in the taskbar options I made sure to have it remember recently open items). How can I restore the original functionality, given that all other pinned applications jump lists work correctly? I'm running Windows 7 Ultimate x64, updated with the latest patches. The OS is in US English and my locale is Italian-Italy.

• Cannot see http (apache) server outside home network

  - by user165155

  Ive been racking my brain with this all evening. Power went out with a tstorm today, started back up my server... running apache and a team speak server on it. TS is great, cant see my web page outside my network! Firewall is disabled on the pc running it (centos btw), apache is running and working. correct ports are forwarded on my router (my isp blocks port 80). Ive tried changing ports, pretty much everything i can think of. httpd.conf is pointing to the correct addy and port, and my domain is pointing to the correct external ip. Im at a loss, any ideas out there?

• sendmail: how can I restrict access to clients that only have a valid certificate?

  - by lxg

  I want to reject all connections that don't present a valid SSL/TLS certificate. First of all is the access db file the correct one to be changing? I have already tried using the basic rule given in the documentation CertIssuer:/C=US/ST=California/O=endmail.org/OU=private/CN= Darth+20Mail+20+28Cert+29/[email protected] RELAY This will obviously need a rule afterward to filter and reject all that don't present the cert? Does anyone have any pointers as to what syntax I should use? wildcards? lxg

• VMXNET3 nic loses the ability to update ARP table after N hours

  - by Peter

  I have a fedora 18 VM that stops updating the arp table on eth1 after running for a number of hours to days. There are other VMs on the same hypervisor that can access all of the same networks without issue. A tcpdump of the offending NIC shows only ARP broadcasts but no responses. None of the other VMs on the vDS see the ARP broadcasts from the offending NIC. The only way I can currently solve the problem is to reboot the VM and then everything works for a while. I've tried changing the port on the vDS and even flipping the network configurations after I lose eth1's ARP table, but the ARP problem follows eth1 but I can access the machines that were originally on eth1. If I statically add the arp entries for machines on the same subnet I have no problems with connectivity. The Hypervisor is an HP BL49X series with flex-10 network modules. Has anyone seen anything like this before?

• SQL Server 2005 Agent running SSIS job can't find file path

  - by alimack

  Basically I'm trying to run a functioning SSIS job (created in BIDS) under the SQL Server Agent - it reads a set of Excel spreadsheets and dumps the results into a table. The problem I'm having is getting the SSA to read the file path, the relevant part of the error is: "0x80004005 Description: "'N:\Assets Property & Facilities Management\Monthly Absence.xls' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides." I've tried using UNC paths (\servername\ share) but the BIDS rewrites the paths to standard file paths (c:\directory\filename), I've also tried a proxy which runs this step under an Admin account. I've also tried changing the path to UNC on the SSIS job on the server. Also I'm forcing it to use the 32 bit DTEXEC, so it's not that either Always get the same error, do I need to re-create the job from scratch?

• MIDI Over Networking on OSX: Lots of beachballing

  - by Yar

  I have 4 computers connected to a Wifi router (with no Internet uplink). Whenever we enter the Network interface for Audio/Midi preferences in ANY of the computers, the Mac beachballs and then finally finds its way. Occasionally, however, one of the computers fails to receive the MIDI information that was destined for it via the Network MIDI interface. Changing to all wired connections does NOT help. Adding Internet uplink DOES help and the problem is resolved. This makes no sense to me as the computers can access each other just fine with or without the Internet uplink. Any ideas? [NOTE: I'll update the question if people correct my terminology, or feel free to do that if you have the rights].

• Apache - Include conf Files Relative to ServerConfigFile (-f arg)

  - by Synetech inc.

  Hi, I want to use the -f command-line option for the Apache server so that I can store the conf files in a separate place (a data diectory) from the server binaries. The problem is that I use the Include directive to separate and organize the configurations, but when I use a command like Include "addons/SVN.conf", it fails because Apache looks for addons/SVN.conf in relative to the ServerRoot directory instead of the ServerConfigFile directory. I can work around this by using absolute paths (eg Include "e:\foo\bar\baz\Apache\conf\addons\svn.conf", but I don’t like that since it means I would have to change each and every Include directive if I move the conf folder as opposed to simply changing the -f option. Does anyone know of a way to get the Include directive to work relative to the conf file that Apache is passed. I tried Include "./addons/SVN.conf", but that too was relative to the ServerRoot. This forced relative-to-ServerRoot Include behavior kind of defeats the whole purpose of specifying an alternate config file to the one in ServerRoot/conf. Thanks.

• Is it possible to edit the web pages in the Profile Manager (OSX Lion Server) user portal?

  - by sglantz

  When setting up Profile Manager in Lion Server, there are a few web pages that are generated for web management of both devices and profiles. Is it possible to edit these pages in any way? I am just looking to customize the look and feel without changing the functionality. If editing is possible, where are these pages stored? I have looked through the /Library/Server/ProfileManager and /Library/Server/Web folders without any luck. This is one particular page I would like to edit. Ideally I would like to be able to edit the HTML directly. I am looking to match the page's style with a variety of other pages hosted on the server.

• Windows 7 x64 how to verify integrity of ALL files on an NTFS disk?

  - by kilves76

  Looking for a tool that would verify integrity of ALL files on a Windows 7 x64 NTFS disk reliably? This is for testing of experimental defrag software, so it really needs to be secure and foolproof. I know it will take a long time, there's millions of files on the disk, but safety just cannot be compromised in a situation like this. Freeware solution much preferred. Can be either Windows software (=inducing pitfalls about files changing due to booting Windows) or a stand alone boot (for example linux boot cd + usb key for storing chksum/metadata).

• SQL 2008 Reporting Services Report Manager blank on Win 7

  - by Daniel Root

  I have installed SQL Server 2008 Reporting Services on my development laptop running windows 7. When I browse to the report manager, only the header is shown. The content pane is blank, and there is no 'Site Settings' option, New Folder options, etc. I found plenty of similar stories about SQL 2005, and then the fix was to manage permissions in the virtual directory in IIS. However, in 2008, there is no virtual directory - RS manages this outside of IIS. Per other serverfault articles, I've tried the following: adding my account to the reporting services group changing the service to run as local system made sure localhost was trusted site in IE ran IE as admin installed SQL Server 2008 SP1 There are no errors in the event viewer. Perhaps related, if I browse to the webservice, I also get the error: The permissions granted to user 'Computer\User' are insufficient for performing this operation. (rsAccessDenied)

• Apache - how to serve pages with users other than www-data

  - by johnlai2004

  I have a webserver that uses apache. When I do a ls -l on /var/www/project1/public_html and /var/www/project2/public_html, I see that they are owned by projectuser1 and projectuser2 respectively. On some of other servers I've looked at, both /var/www/project1/public_html and /var/www/project2/public_html are owned by only www-data. How would I go about changing these ownerships to projectuser1 and projectuser2 such that these new users can login to their areas and manage their own websites? I created a user projectuser1 then did a chown -R projectuser1 /var/www/project1, but any time projectuser1 adds a new file to the directory, Apache gives me a Permission Error. If do a chown -R www-data /var/www/project1, then everything works again. Ultimately, I want apache to serve the /var/www/project1 directory with projectuser1 owning it.

• Python installation in OSX not updating

  - by ElendilTheTall

  I've recently got into Python programming and so downloaded the latest version (3.2.3) to install on my Mac running Snow Leopard. I used the installer package. I have run the shell profile update script, but Terminal is still using 2.6.1 to run my programs. I have tried changing the paths with sudo nano as per this post but it makes no difference - it still uses 2.6.1 Any ideas, oh mighty Super Users? I am a complete noob when it comes to Terminal commands.

• A specific user is unable to log in to vsftpd

  - by HackToHell

  I am setting up a new user let his name be ftpguy. He has access to only one directory /var/www/xxx. I have already chowned the directory so that he has write and read privileges. The user is also unable to login via ssh as I have disabled that by changing his shell to /sbin/nologin. Also, in vsftpd config, I have enabled the chroot_local_user. Now whenever I log in from ftp, i get an auth error. Connect socket #1008 to xxxxxxxx, port 21... 220 Welcome to blah FTP service. USER ftpguy 331 Please specify the password. PASS ********** 530 Login incorrect. I changed the password to something different several times, using the passwd command, nothing happens, i still the above error. However I am able to log in with my ssh creditals to my ftp server without any problems.(I do not use a key).

• How to check sshd log?

  - by Eye of Hell

  Hello. I have Ubuntu 9.10 installed with sshd and i can successfully connect to it using login and password. I have configured an RSA key login and now have "Server refused our key" as expected. Ok, now i want to check sshd log in order to fingure out a problem. I have examined /etc/ssh/sshd_config and it have SyslogFacility AUTH LogLevel INFO Ok. I'm looking at /var/log/auth.log and... it's empty O_O. Changing Loglevel to VERBOSE helps nothing - auth.log is still empty. Any hints how i can check sshd log?

• How does "Compatability Mode" in Windows 7 affect the application?

  - by Robert C. Cartaino

  Background: Based on the answer given to this question: "Skype behaviour in the Windows 7 Superbar" ...you can get Skype to minimize to the system tray (rather than the task bar) by running it in compatibility mode. (red flags going off in my head) That's the behavior that I want but what does "compatibility mode" do to the executing application? I am concerned about changing the execution mode of an entire (important) application to a previous generation just to alter the user interface behavior a bit. So, what does compatibility mode actually do internally? What are the disadvantages, as in "how could the application (Skype) suffer?"

• Memory consumption of each accept() call on server running on Windows 2008 [migrated]

  - by Atul

  I've written a simple and small server application on Windows 2008 that just accepts connections and does nothing else. I am doing memory footprint assessment of socket calls, What I found that each connection (after accept()) consumes at least 2.5 KB of memory. Interestingly, the memory is not consumed by the process that has accept() call but it consumed by a OS process. I believe it might be because of data structures being created inside OS for each connection. Now, I have two key questions: Is it possible by any means to reduce this memory footprint (by changing any parameters, configuration etc) ? If yes how ? (Because 2K for each connection would be too much if we planning server to accept millions of connections) If my server is intended to accept million connections, is it good idea to use Windows 2008 ? or shall I switch to some other OS? Please advice me.

• How to correct time on Windows PDC server without affecting logons

  - by Kieran Walsh

  I know how to set an authoritative time server in Server 2008 R2. That's not what this question is. I want to know how I can change the time on a network where the PDC (and therefore everything) is a month out of date? I know that a 5 minute difference in time between clients and the domain prevents logons, so just changing the time on the PDC will break everything. What is the best way to fix this? Thanks Kieran.

• Reverse Proxy Methods for Hosting a Low-Bandwidth Dynamic Website

  - by Casey

  I am building a webcam w/ HTTP server that will be running from a low-bandwith connection. The content on the site will be changing every 5 to 10 minutes. Instead of serving files directly from this connection, are there hosting companies that can act as a reverse proxy for my site? Therefore, if nobody is using the site, the local internet connection remains idle. And if I receive 1000 hits all at the same time, only one HTTP GET is required, and the hosting company (on a fat pipe) continues serving the other 999 requests? This doesn't sound like a very common usage model, but I feel like this would be the optimal solution to my situation.

• Mail server hammering

  - by Rodrigo

  I've noticed a quick increase on smtp connections coming to my server, investigating it further i figured out that there's a botnet hammering my smtp server. I've tried to stop it by adding a rule at iptables: -N SMTP-BLOCK -A SMTP-BLOCK -m limit --limit 1/m --limit-burst 3 -j LOG --log-level notice --log-prefix "iptables SMTP-BLOCK " -A SMTP-BLOCK -m recent --name SMTPBLOCK --set -j DROP -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --name SMTPBLOCK --rcheck --seconds 360 -j SMTP-BLOCK -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --name SMTP --set -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --name SMTP --rcheck --seconds 60 --hitcount 3 -j SMTP-BLOCK -A INPUT -p tcp --dport 25 -m state --state NEW -j ACCEPT That would avoid them from hammering "too fast", however the problem still, there's like 5 tries per second, it's going insane, i had to incrase the maximum number of childs of sendmail/dovecot. There's too many ips to filter out manually and simply changing the smtp to another port is not practical since i got many other clients on that server. I'm using sendmail with dovecot, any ideas to have this filtered out more efficiently?
