• How to protect an OS X Server from an unauthorized physical connection?

  - by GJ

  Hi I have an OS X 10.6 server, which I administer via SSH and VNC (via SSH tunnel). I can't leave it at the login window since then VNC connections are refused. Therefore I currently leave it logged with my user account. Since it doesn't have a monitor attached, it doesn't go into screen saver mode, which means it doesn't require a password to retake control. This means it is very easy for anyone connecting a keyboard/mouse and monitor to take control of the system. The screen saver password protection, which I can't get to activate, unlike the system's login window, is perfectly compatible with VNC connections. How could I prevent such direct access to the server without connecting a monitor and without blocking my ability to connect with VNC? Thanks!

  - by Eng Al-Rawabdeh

• How do you sync photos with your family?

  - by romkyns

  We've always been trying to share photos within our family, despite all living in different countries. This has been very challenging. We have about 50GB of photos that we share with each other. Everyone organizes them differently, so rsync/Syncplicity don't work. Everyone likes their photos on the fast hard drive rather than a slow website with reduced quality, so online sharing websites are a no-go. So far we have been essentially syncing them manually, via a shared folder that new photos are placed to and collected from. This is laborious and prone to errors, that usually leave one of us without all the photos without even knowing. To those who are in a similar situation, how do you solve this?

• Firefox completes the address bar with content absent from my history

  - by Antoine

  I have set Firefox to complete the address bar with elements from the history only ( other options are: nothing, bookmarks, and a history+bookmarks). However, Firefox still continues to complete the address bar with elements that are no longer in my history. A search in the history returns 0 result for the incriminated string. How can I solve this without loosing my entire history? I have already tried shift+delete on the elements I would like to delete, without success. How can I find the source of a certain completion ? (like an SQL request in the sqlite3 files used to store history) I'm using Firefox 16.0.2 on OS X 10.8.2.

• Point example.com to webserver in DNS record

  - by ggstevens

  I have a Mac Mini Server (named Server) with the following DNS setup Primary Zone: example.com mysql-host.example.com machine (10.0.0.101) server.example.com machine (10.0.0.100) server.example.com nameserver (10.0.0.100) www.example.com machine (10.0.0.102) www.example.com is a linux box with Apache. How do I get both example.com and www.example.com to work. Right now, I can view my website with www.example.com only. I know there's nothing that points example.com to the IP, but when I create a machine record without a hostname I get an error (This machine record cannot be created without a host name.).

• When connected through a router, a new gateway appears, and I lose my internet connection.

  - by idan315

  I have two computers connected to a router, connected to my ADSL modem by PPPoE. One of those computrs use Windows XP, the other uses Windows 7. The computer using Windows 7 keeps getting limited or no connectivity, and I can't use it to connect to the internet. Connecting the computer to the modem without the router 'in the way' worked, and I was able to use the internet - which led me to believe that the problem is with my router. However, I have changed my router, and the problem persists. (Just to be clear: the computer using Windows XP can connect to the internet without any problem). This entire question is about the PC using Windows 7. The only symptom of this problem is that when I see my network devices, in addition to my router (which appears as "Network 4", or something of the sort), I also see an "Unidentified Network". When using ipconfig to check the problem, I see a second gateway, with the IP 0.0.0.0, in addition to the IP of my router.

• Automatically mount a remote folder on boot

  - by Andrew

  I'm trying to mount a Windows folder on my Ubuntu machine on start up. I've tried following this page here, modifying /etc/fstab and appending sshfs#my_user@remote_host:/path/to/directory <local_mount_point> fuse user 0 0 to it, but it fails; on start up, I get an error saying that the mounting failed, and I can press S to skip or M to recover manually. I also tried following this page here, appending /usr/bin/sshfs -o idmap=user my_user@remote_host:/path/to/directory <local_mount_point> to the /etc/rc.local file, but this doesn't help either; Ubuntu just boots up normally without mounting. I have Cygwin installed on my Windows machine, and I can run everything smoothly, such as sshing without passwords, and mounting it manually. I've also tried to run the modified rc.local file $ /etc/rc.local, and it works perfectly, but I just can't seem to get the folder mounted on start up. Can someone help me?

• Is there an encrypted write-only file system for Linux?

  - by Grumbel

  I am searching for an encrypted filesystem for Linux that can be mounted in a write-only mode, by that I mean you should be able to mount it without supplying a password, yet still be able to write/append files, but neither should you be able to read the files you have written nor read the files already on the filesystem. Access to the files should only be given when the filesystem is mounted via the password. The purpose of this is to write log files or similar data that is only written, but never modified, without having the files themselves be exposed. File permissions don't help here as I want the data to be inaccessible even when the system is fully compromised. Does such a thing exist on Linux? Or if not, what would be the best alternative to create encrypted log files? My current workaround consists of simply piping the data through gpg --encrypt, which works, but is very cumbersome, as you can't easily get access to the filesystem as a whole, you have to pipe each file through gpg --decrypt manually.

• Download a file via HTTP from a script in Windows

  - by Jason R. Coombs

  I want a way to download a file via HTTP given its URL (similar to how wget works). I've seen the answers to this question, but I have two changes to the requirements: I'd like it to run on Windows 7 or later (though if it works on Windows XP, that's a bonus). I need to be able to do this on a stock machine with nothing but the script, which should be text that could be easily entered on a keyboard or copy/pasted. The shorter, the better. So, essentially, I'd like a .cmd (batch) script, VBScript, or Powershell script that can accomplish the download. It could use COM or invoke IE, but it needs to run without any input, and should behave well when invoked without a display (such as through a telnet session).

• OpenSSH SFTP: chrooted user with access to other chrooted users' files

  - by HannesFostie

  Decided to re-phrase the question entirely in order to not have to make a new one. I currently have an SFTP server set up using OpenSSH's SFTP functionality. All my users are chrooted, and everything works. What I need most right now is for one user, which is not root (because this user can't have any real SSH powers!), to have access to all other users' chrooted dirs. This user's job is to fetch all uploaded documents every once in a while. Directory structure as of now is: /home |_ /home/user1 |_ /home/user2 |_ /home/user3 With ChrootDirectory set as /home/%u User "adminuser" should have access to user1, user2 and user3's directories without having access to /home or at the very least not to anything but /home. Bonus points for the one who can tell me how to let users write inside /home/%u without having to make a new directory inside that dir which they own themselves, and not root as is the case with /home/%u (openssh chroot prerequisite).

• Mysql innoDB corruption after server crash

  - by Ward Loockx

  Yesterday my server died because an outage in the data center. Today it's back up, but having some problems with mysql. First of all my mysql server was not able to start. For this reason I deleted the files ib_logfile0 and ib_logfile1 in /var/lib/mysql folder (I still have the old failing files). After this my server was able to startup again. But now I see a lot of issues in the mysql log file. Sep 1 09:43:55 * mysqld: 120901 9:43:55 InnoDB: Error: page 70944 log sequence number 8 1483471899 Sep 1 09:43:55 * mysqld: InnoDB: is in the future! Current system log sequence number 5 612394935. Sep 1 09:43:55 * mysqld: InnoDB: Your database may be corrupt or you may have copied the InnoDB Sep 1 09:43:55 * mysqld: InnoDB: tablespace but not the InnoDB log files. See Sep 1 09:43:55 * mysqld: InnoDB: http://dev.mysql.com/doc/refman/5.1/en/forcing-recovery.html When I check the docs on mysql.com, I found that I need to recover my database with backups. I have a backup but not sure what's the good way on importing it. Or is there a way to recover without having to re-import the database again? So if I'm correct I need to put innodb_force_recovery to 4 in mysql and delete all current data and re-import? Is there a way to do this without having downtime? I also have one slave running. This slave has the current status now: Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. How can I totally reset the slave after the new import on the master has happend? Hopefully we can find a solution without not to much downtime. Thanks!

• Windows 7 stopped connecting to samba share

  - by Jan

  I have a problem with Windows 7 Home connecting to samba on linux server. It's worked fine for a year and without any changes in configuration or updates it suddenly stopped working. The strangest thing for me is that it stopped working for no reason that I could think of. After a few minutes after trying to connect I get: \\ip is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Other computers in that network (XP machines) connect to samba without any problem. I've tried adding LmCompatibilityLevel as described here: http://www.tomshardware.com/forum/75-63-windows-samba-issue , but it didn't help.

• Handling FreeBSD package upgrades using pkg_add

  - by larsks

  I'm trying to use FreeBSD's pkg_add command to install and upgrade binary packages in a build-once-install-on-multiple-machines sort of scenario. It works well when installing a new package, but upgrades are baffling me. For example, if I want to upgrade a package that is depended on by another package, I can't just install it: # pkg_add /path/to/somepackage-2.0.tbz pkg_add: package 'somepackage' or its older version already installed At this point, I can delete the older version of the package if I pass -f to the pkg_delete command: # pkg_delete -f somepackage-1.0 pkg_delete: package 'somepackage-1.0' is required by these other packages and may not be deinstalled (but I'll delete it anyway): anotherpackage-1.0 But...and this is the killer...now the dependency information is gone! I can install the upgrade: # pkg_add /path/to/somepackage-2.0.tbz And now attempts to delete it will succeed without any errors: # pkg_delete somepackage-2.0 How do I handle this gracefully (whereby "gracefully" means "in a fashion that preserves dependency information without requiring me to rebuild/reinstall and entire dependency chain"). Thanks!

• Difficulty racking HP ProLiant Gen8 servers

  - by Systemspoet

  We're an all Proliant shop with around 50 servers, mostly DL360s and DL380, from G5's through G7's. We just got our first two G8's in and went to rack them. We were stunned to find out that the new cable management arms protrude almost 1 inch deeper into the rack then previous iterations of the Proliant line. Unfortunately that causes them to occupy the same space as the PDU's in our APC racks. In a non-densely populated section of rack that's no biggie, but in a densely populated section it's impossible to get the cable arm into place without dislodging another machine's power. Has anyone else run into this? Obviously racking machines without cable management arms is not an option. I supposed we could reconfigure our racks but that's a nightmare.

• Rebuild an existing Rackspace server from scratch?

  - by Mojo

  In the process of working out kinks in a server build, is it possible to re-bootstrap a server from scratch, image and all? (Same flavor, say.) By that I mean without recreating the server, keeping its IP address if nothing else. I can't find a way to do this. It would have some advantages, I should think: It wouldn't decrement the 'server create' quota. The existing server would keep its IP address. One machine of a cluster could be rebuilt to a new image without having to change the IP address. (Maybe load balancers make IP addresses a moot point, but it still seems like a worthwhile task.)

• MySQL wants a password but it's empty

  - by gAMBOOKa

  mysql -uroot ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) mysql -uroot -p Enter password: <-- leave blank, hit enter without entering anything mysql> <-- i am logged in NOTE: This is a new mysql instance installation So if the password is blank, why won't it log me in without a -p flag? For a little clarification. I am running into this issue when attempting to change the password using a script: We're using a bash script to do that. mysqladmin -u root password abc wouldn't work (access denied) mysqladmin -u root -p password abc cannot be used because it prompts for a password and we need to automate this. mysqladmin -u root -p'' password abc is not working either

• Unable to boot fedora 11

  - by csunwold

  I have been running fedora 11 for several months without a hiccup, but two days ago I ran "yum update" and installed whatever updates were available (I didn't pay attention to what they were). I was having problems with mysql so I tried "yum remove mysql" and then it removed mysql as well as quite a few unexpected dependencies. I then "yum install mysql" without a hitch and went about my way. However, when I next booted up my machine it got to "Starting preload dameon [OK]" and then it hangs with a flashing cursor on the screen. I tried following http://dailypackage.fedorabook.com/i...ling-Grub.html but it didn't seem to make any difference. I put a new hard drive with WinXP on it into the same machine that I booted to, and I tried to use Ext2 Installable File System for Windows but when I run it, it only seems to see /boot and nothing else on the hard drive. Any ideas?

• Apache Rewrite Rules breaking each other?

  - by neezer

  I have this rule: RewriteCond %{REQUEST_URI} ^/(manhattan|queens|westchester|new-jersey|bronx|brooklyn)-apartments/.*$ RewriteCond %{REQUEST_URI} !^/guide/(.*)$ RewriteRule ^(.*)$ /home/neezer/public-html/domain.com/guide/$1 [L] Which works great on it's own. Essentially, I have a bunch of directories that have a bunch of files in them that I want to keep in the "/guide" folder, but I want them to appear at the web root for SEO reasons. This rule works, but unfortunately the original URL's still work too (with "/guide"). I want to 301 Redirect the ones with "/guide" in the URL to those without, without actually moving the files on the server. I tried adding this rule: RewriteCond %{REQUEST_URI} ^/guide/(manhattan|queens|westchester|new-jersey|bronx|brooklyn)-apartments/.*$ RewriteRule ^guide/(.*)$ http://www.domain.com/$1 [R=301,L] ... but that breaks my first rule completely. Any thoughts about what I might be doing wrong? Please let me know if you need to know anything else from me to help me with this issue.

• How to show a warning message when entering a folder?

  - by Valter Henrique

  I don't know if this is possible, but, I have a folder which I would like to show some warning message when the user enters in it. In my case would say that the folder could be deleted without previous warning to save some disk space. I already create a file inside the folder with the warning message: WARNING! ########################################################################################################################################################## Please, be advised, that the folder /company-backup/amazon-s3 can be deleted without previous WARNING to save disk space as the INFRASTRUCTURE TEAM judge necessary. Best regards, Infrastructure Team. ########################################################################################################################################################### Is that possible ? Any idea ?

• How to color highlight text in a black/white document easily

  - by Lateron

  I am editing a 96 chapter book. The text is in normal black letters on a white background. What I want to be able to do is: I want to have any changes or additions automatically shown in another (per-selected) color. Without having to a)high lite a word or phrase to be changed or added and then b)going to the toolbar and clicking on the font color In other words I want the original color of the text to remain as it is and any additions or changes to be visible in another color without having to use the toolbar. Can this be done? I use OpenOffice or Word 2007 in Windows 7.

• Issue with Toshiba Satellite C50 A-1JM

  - by Nathan Hawkes

  I am having some odd problems with my Toshiba laptop. For the last two days, it has not loaded past the boot screen for hours, if at all. When I force the laptop off and switch it back on, it goes to the Preparing Automatic Repair process but will not complete the process and go to the desktop. However, this only happens when the battery is plugged in. When I remove the battery and run the laptop on power, it works without issue. Would this be a battery issue (given it works without the battery) or a hard drive issue (given it won't get past the boot screen)? If neither, what would you suggest as a solution?

• Acad 14 SOLIDS disappeared, DWG file doesn't open correctly

  - by MikeD

  I made a drawing in Autocad 14 (Win XP) containing of mostly SOLID's. I saved and re-opened it multiple times without any problem. Before I last saved it I viewed my drawing using the SHADE functions. After re-opening all my SOLIDS have disappeared. I spent numerous hours searching for a solution, tried SATFIX.ARX , AUDIT, RECOVER without success (ACIS error - which should be gone after applying SATFIX), changed my computer locale from German (decimal = comma) to English (decimal = dot) but my screen remains empty (and yes I tried to recover from a .BAK, too) I also tried to export (the non-display drawing) into DXF and can confirm that all my objects are in there, but re-opening the DXF results in a huge ACIS error list again I am desperate - please can someone help - thanks!
