• Family server setup

  - by Manny

  Hi all, I really hope some of you can give me some direction. I have setup a linux server at home and through samba I can access files from different computers in my home. I would like to use this server as a file-server for my family (brothers, sisters and parents who all live in their own homes). I really like the way it is set up right now with user and permission controls, but I've read that it is bad idea to open up the samba port to the world. The requirements are simple: 1) it should be easy to access, by using standard web browsers or mounting the drive (shouldn't have to use any VPN setup or use putty etc) 2) should be somewhat secure. We just want to share family pictures instead of putting them on facebook or picasa or other web server, nothing top secret. Here is what I've looked into: 1)Webdav. It seems decent but seems like it windows7 doesn't like it very much, even with digest mode authentication. User controls and permissions are not as flexible as samba (or at least to my knowledge). I really like the user and group permissions in samba, but if I could live with webdav if it worked seamlessly with windows, it should just work shouldn't it? 2) I read somewhere to stay away from ftp as it is outdated and that there are newer and better internet file-server setups? Was that a reference to webdav? I am so confused, please help... Manny

• MySQL based authentication with crypt()ed password fails in Apache 2.2

  - by Fester Bestertester

  I'm trying to set up a simple CalDAV/CardDAV server with a Radicale backend and an Apache 2.2 frontend. So far, it's all nice and simple, but I can't get the MySQL based authentication to work. I'd like to authenticate users against an existing MySQL database, and I need the REMOTE_USER variable to be set (pretty much like in the configuration examples for Radicale). I've tried mod_auth_mysql, which authenticated the users nicely, but failed to set the REMOTE_USER variable. The newer alternative seems to be mod_authn_dbd, which doesn't seem to like the crypted passwords in the MySQL database. According to the documentation, crypted passwords should work, so maybe I'm just missing a simple parameter. The configuration looks like this: DBDriver mysql DBDParams "sock=/var/run/mysqld/mysqld.sock dbname=myAuthDB user=myAuthUser pass=myAuthPW <Directory /> AllowOverride None Order allow,deny allow from all AuthName 'CalDav' AuthType Basic AuthBasicProvider dbd require valid-user AuthDBDUserPWQuery "SELECT crypt FROM myAuthTable WHERE id=%s" </Directory> I've tested the query, it works fine. And as mentioned before, mod_auth_mysql worked nicely against the same database, but didn't set the required variables. Am I just missing some configuration parameter? Or is mod_authn_dbd just not the right tool to achieve what I want?

• Discrepancy in file size on disk and ls output

  - by smokinguns

  I have a script that checks for gzipped file sizes greater than 1MB and outputs files along with their sizes as a report. This is the code: myReport=`ls -ltrh "$somePath" | egrep '\.gz$' | awk '{print $9,"=>",$5}'` # Count files that exceed 1MB oversizeFiles=`find "$somePath" -maxdepth 1 -size +1M -iname "*.gz" -print0 | xargs -0 ls -lh | wc -l` if [ $oversizeFiles -eq 0 ];then status="PASS" else status="CHECK FAILED. FOUND FILES GREATER THAN 1MB" fi echo -e $status"\n"$myReport The problem is that ls command outputs the files sizes as 1.0MB in the report but the status is "FAIL" as "$oversizeFiles" variable's value is 2. I checked the file sizes on disk and 2 files are 1.1MB. Why this discrepancy? How should I modify the script so that I can generate an accurate report? BTW, I'm on a Mac. Here is what man page for "find" says on my Mac OSX: -size n[ckMGTP] True if the file's size, rounded up, in 512-byte blocks is n. If n is followed by a c,then the primary is true if the file's size is n bytes (characters). Similarly if n is followed by a scale indicator then the file's size is compared to n scaled as: k kilobytes (1024 bytes) M megabytes (1024 kilobytes) G gigabytes (1024 megabytes) T terabytes (1024 gigabytes) P petabytes (1024 terabytes)

• Windows 2008 R2 file share - any way to "lock it down" outside of a 3rd party app?

  - by TheCleaner

  I have a 3rd party app that "makes a call" to write files to a file share on our network using the currently logged in credentials of the Windows domain user. Meaning the 3rd party app doesn't pass the apps credentials but simply issues a behind the scenes copy command to take a source file specified and copy/move it to the destination "repository" on the file share. The basic premise is that it keeps revisions/approvals for Document Control (think svn/git I guess, similar to this question: Lock down Windows folder to only be updatable by SVN). This all works fine...but here's my issue: I need a way to lock down the file share from being accessed/modified outside of using the 3rd party app (meaning prevent explorer/word/excel/etc from getting to that share). I know I can do the following: make the share a hidden share ($) - this definitely helps. Most users would have zero clue on how to get to such a share. Solves probably 95% of my issue. go one step further and set the "Hidden" attribute on the folders in the hidden share - this would go a little further in that even if a user knows the path to the hidden share like \\server\hidden$ they still won't see folders in that share without changing their explorer options to "show hidden files/folder Any other ideas on how I can lock this down? The users still need modify rights to this share/folders since the 3rd party app relies on their Windows permissions to that location when copying the files into it. I can't really use 3rd party tools to password protect the folder/share without causing the 3rd party app functions to fail.

• TCP Keepalive and firewall killing idle sessions

  - by Carlos A. Ibarra

  In a customer site, the network team added a firewall between the client and the server. This is causing idle connections to get disconnected after about 40 minutes of idle time. The network people say that the firewall doesn't have any idle connection timeout, but the fact is that the idle connections get broken. In order to get around this, we first configured the server (a Linux machine) with TCP keepalives turned on with tcp_keepalive_time=300, tcp_keepalive_intvl=300, and tcp_keepalive_probes=30000. This works, and the connections stay viable for days or more. However, we would also like the server to detect dead clients and kill the connection, so we changed the settings to time=300,intvl=180,probes=10, thinking that if the client was indeed alive, the server would probe every 300s (5 minutes) and the client would respond with an ACK and that would keep the firewall from seeing this as an idle connection and killing it. If the client was dead, after 10 probes, the server would abort the connection. To our surprise, the idle but alive connections get killed after about 40 minutes as before. Wireshark running on the client side shows no keepalives at all between the server and client, even when keepalives are enabled on the server. What could be happening here? If the keepalive settings on the server are time=300,intvl=180,probes=10, I would expect that if the client is alive but idle, the server would send keepalive probes every 300 seconds and leave the connection alone, and if the client is dead, it would send one after 300 seconds, then 9 more probes every 180 seconds before killing the connection. Am I right? One possibility is that the firewall is somehow intercepting the keepalive probes from the server and failing to pass them on to the client, and the fact that it got a probe makes it think that the connection is active. Is this common behavior for a firewall? We don't know what kind of firewall is involved. The server is a Teradata node and the connection is from a Teradata client utility to the database server, port 1025 on the server side, but we have seen the same problem with an SSH connection so we think it affects all TCP connections.

• Bad HD and robocopy

  - by acidzombie24

  After my HD gave me crc errors I wanted to copy one drive to another and picked up a new 1TB hd. I am using the command robocopy G: J: /MIR /COPYALL /ZB First it tried copying the file a few times (i didnt count, its not in my window anymore) and got an access denied error, error 5. Then it tried again and locked up. I tried copying that specific file (14mb) and windows says "cant read from source file or disk". I started robocopy again. Hopefully it will ignore it after a fail attempt or two but what options can i use to say if it doesnt work continue to the next file. It looked like that is what it was doing but for this last one it repeated more then 4times and locked up finally. I'm open to other copy solutions. I do prefer built in solutions. I am using windows 7 Also how might i do this without the /MIR option. Is /S /E good enough? flag reference here -edit- i see i can control retries with /R: but i am still open to alternative solutions.

• What can I do with a home server?

  - by Joel Coehoorn

  I have an old 700 Mhz Pentium III at home running Windows 2000 Server, with a home router set up to pass incoming requests to it and a DynDNS account set up so it's easy to find. Right now I'm using it for a number of things: Shared folders + backup inside the home network Shared Printer inside the home network Domain Controller, just because I feel like it and because it's useful to me as practice to keep those "enterprise" administration skills. Web Server FTP remote access for my files. I abandoned this for security reasons, but it's still worth leaving visible. Remote Desktop in to the home network (thinking about adding VPN service) SVN repository MySQL - Will be moving to SQL Server 2008 Standard soon. After I upgrade my wife's laptop from home to pro later this year it will also become a domain controller It's the only place I still have access to Internet Explorer 6 any more without setting up a new virtual machine, so I use it for testing code with that browser. The question is: What else could I be doing with this machine? Update Additional ideas based on the suggestions: Media Server/DVR Build server PBX SSH Proxy Server Continuous Integration Server Personal OpenID Provider Update2 Just a note that this server was recently upgraded to an Atom330 with 2 GB ram and bigger hard drive. For all that's slow for a "modern" cpu, it should still be much faster than the old Pentium III and the expected power savings should make the upgrade essentially free over the course of the next year or two. Also, it's now running Windows Server 2008.

• What user information is exposed via a browser?

  - by ipso

  Is there a function or website that can collect and display ALL of the user information that can be obtained via a browser? Background: This of course does not account for the significant cross-reference abilities of large corporations to collate multiple sources and signals from users across various properties, but it's a first step. Ghostery is just a great idea; to show people all of the surreptitious scripts that run on any given website. But what information is available – what is the total set of values stored – that those scripts can collect from? If you login to a search engine and stay logged in but leave their tab, is that company still collecting your webpage viewing and activity from other tabs? Can past or future inputs to pages be captured – say comments on another website? What types of activities are stored as variables in the browser app that can be collected? This is surely a highly complex question, given to countless user scenarios – but my whole point is to be able to cut through all that – and just show the total set of data available at any given point in time. Then you can A/B test and see what is available with in a fresh session with one tab open vs. the same webpage but with 12 tabs open, and a full day of history to boot. (Latest Firefox & Chrome – on Win7, Win8 or Mint13 – although I'd like to think that won't make too much of a difference. Make assumptions. Simple is better.)

• Virtualbox Networking: XP Guest, Ubuntu Host: Connecting to Windows servers & local network?

  - by user51833

  Here's what I have: Windows XP running in VirtualBox 3.0.8_OSE r53138; Host OS = Ubuntu 9.10 "Karmic Koala"; Windows network in my office with smb fileservers; Guest OS is connected to the internet and is sharing folders with Host OS; Limited networking expertise. Here's what I actually need to do: Use MS Outlook in my XP guest with all its calendar-sharing features and stuff (if this is all done through the internet then great) - or find a Linux app that can do the same stuff; Map Windows network servers, eg. smb://server01/ in my XP guest (I can already access these in Ubuntu. Here's what I've tried with no luck: Entering the server address (example above) in my XP guest windows explorer address bar (got a "could not access the file, path or drive" error message - maybe if I could enter login/pass information? But I don't know how); Mapping the server as a network drive (Windows could not find the path); Mounting the server as one of my shared folders (I couldn't find it through the shared folders browser in VirtualBox - is there somewhere in the Linux filesystem that Ubuntu keeps links to mounted servers?).

• How to define nodes from a Hiera file in Puppet?

  - by Pigueiras

  I am using puppet and the puppet network device management module and I am trying to build my custom type. In the built-in type for the routers configuration, you can specify a list of nodes and then the configuration inside that node: node "c2950.domain.com" { Interface { duplex => auto, speed => auto } interface { "FastEthernet 0/1": description => "--> to end-user workstation", mode => access, native_vlan => 1000 # [...] More configuration } What I am trying to do, is to move the manifest declaration of the nodes and the configuration of my custom type to a Hiera file like this one: nodes: - node1 - node2 config_device: node1: custom_parameter: "whatever1" node2: custom_parameter: "whatever2" And then in the manifest iterate over the hiera file creating the nodes with the configuration of each node with something like (I am taking as reference this question in serverfault): class my_class { $nodes = hiera_array('nodes') define hash_extract() { $conf_hash = hiera_hash("config_device") $custom_paramter = $conf_hash[$name] ## TRICK lies in $name variable node $name { my_custom_device { $name: custom_parameter => $device_conf['custom_parameter'] } } } hash_extract{$pdu_names: } } } But for this solution I have two problems, I can not define a node inside a define and I can not parameterize a node name. So, is there any way to declare nodes from a Hiera file with their configuration inside?

• Windows disk change monitoring for malware analysis

  - by SuperDuck

  Not sure if this question belongs to here, because it has some relations with 'serverfault' (system backups) and 'stackoverflow' (software analysis). I'm looking for a solution to monitor disk changes on a Windows system and selectively revert them. It should be able to handle live files like registry parts, so may need to be an offline backup software. It shouldn't silently pass over files which the current admin user doesn't have permissions on (files with no permission entries or owned by the 'system' user) Registry change tracking would be a bonus but is not a requirement I use virtual machines for malware analysis, there is even no solution to list file changes in disk snapshot files (delta VMDK). I currently use Ashampoo for monitoring changes. Though it's the best one between similars, it's not a good software and hasn't really evolved in many 'platinum', 'deluxe' versions released in the last 10 years (it even used non-resizable windows until the latest version). The real problem is it misses some disk / registry changes. Perhaps it only compares modification dates and doesn't catch a change if the dates are preserved. So, I think the solution should compare files using hashes, or file sizes at least. There are numerous backup software out there and I'm sure one can handle this, offline or online.

• What's the best way to get a stored POP3 password out of Outlook 2007?

  - by Tom Morris

  If you have a password for a POP3 account in Outlook 2007 (Windows 7 Home Premium) and you then forget the password, how do you retrieve it? I tried copy-and-paste. No go. I downloaded Mail PassView, but upon installing it, AVG said it was malware, so I removed it. I eventually found the account details by opening up RegEdit, and found it in HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook\ (...) but it was encoded in REG_BINARY. I Googled around and found various Visual Basic routines for decoding it but being a Unix dork I had absolutely no idea what to do with said scripts. By this point, I gave up and managed to get hold of the password by another means (it was written down on a piece of paper in the briefcase of the owner of the account - I know, it makes the inner sysadmin rage). I also attempted to write a simple POP3 server in Python and then get Outlook to log on to it, but that didn't really work out (it was about 4am at that point). For future reference, is there an easy and sensible way of doing this? Is Mail PassView actually evil spyware or was AVG just giving me a false positive? (Any chance of Windows 8 having something like OS X's Keychain?)

• centos install / partitioning

  - by ServerSideX

  I'm using NOC-PS to remotely install Centos 6.2 via KVM / IPMI. I'm going to install cPanel as well and they recommend this layout /boot (99MB) swap (2x server RAM) / (remainder) In the o/s install profile within NOC-PS software, it shows as this: part /boot --fstype ext2 --size 250 part pv.01 --size 1 --grow volgroup vg pv.01 logvol / --vgname=vg --size=1 --grow --fstype ext4 --fsoptions=discard,noatime --name=root logvol /tmp --vgname=vg --size=1024 --fstype ext4 --fsoptions=discard,noatime --name=tmp logvol swap --vgname=vg --recommended --name=swap By the time the default partition setup was done installing Centos, I get this [root@server005 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-root 532G 907M 504G 1% / tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/sda1 243M 28M 202M 13% /boot /dev/mapper/vg-tmp 1008M 34M 924M 4% /tmp [root@server005 ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Fri Dec 7 18:47:24 2012 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg-root / ext4 discard,noatime 1 1 UUID=58b31aaf-5072-4fb1-a858-33bc316fa793 /boot ext2 defaults 1 2 /dev/mapper/vg-tmp /tmp ext4 discard,noatime 1 2 /dev/mapper/vg-swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 My question is, how should the NOC-PS install profile look like to get the recommended cPanel partitioning?

• Redirect from folder containing website

  I have a website reached from this url: http://www.mysite.com/cms/index.php being served from this directory: public_html/cms/index.php In public_html I have this .htaccess RewriteRule (.*) cms/$1 [L] Which lets me get to the site like this: http://www.mysite.com/index.php But now if I reference the 'old' address, I'd like to redirect to the rewritten address with a permanent redirect code. for example: http://www.mysite.com/cms/?q=node/1 is redirected to... http://www.mysite.com/?q=node/1 How can I make this happen?

• Securing NTP: which method to use?

  - by Harry

  Can someone good at NTP configuration please share which method is the best/easiest to implement a secure, tamper-proof version of NTP? Here are some difficulties... I don't have the luxury of having my own stratum 0 time source, so must rely on external time servers. Should I read up on the AutoKey method or should I try to go the MD5 route? Based on what I know about symmetric cryptography, it seems that the MD5 method relies on a pre-agreed set of keys (symmetric cryptography) between the client and the server, and, so, is prone to man-in-the-middle attack. AutoKey, on the other hand, does not appear to work behind a NAT or a masquerading host. Is this still true, by the way? (This reference link is dated 2004, so I'm not sure what is the state of art today.) 4.1 Are public AutoKey-talking time servers available? I browsed through the NTP book by David Mills. The book looks excellent in a way (coming from the NTP creator after all), but the information therein is also overwhelming. I just need to first configure a secure version of NTP and then may be later worry about its architectural and engineering underpinnings. Can someone please wade me through these drowning NTP waters? Don't necessarily need a working config from you, just info on which NTP mode/config to try and may be also a public time server that supports that mode/config. Many thanks, /HS

• Upgrading PHP, MySQL old-passwords issue

  - by Rushyo

  I've inherited a Windows 2k3 server running an XAMPP-installation from the stone age. I needed to upgrade PHP to facilitate an upgrade to MediaWiki to facilitate a new MediaWiki extension (to facilitate some documentation to facilitate doing my job to facilitate getting paid to facilit... you get the idea). However... installing a new version of PHP resulted in PHP's MySQL libraries refusing to communicate using MySQL's 'old style' 152-bit passwords. Not a problem in theory. The MySQL installation is post-4.1, so it should have the functionality to upgrade the user's passwords from 152-bit to 328-bit (what a weird hashing algorithm...). I ran the following: SET PASSWORD = PASSWORD('foo'); on MySQL but querying: SELECT user, password FROM mysql.user; returned just the same password I started out with - 152-bit. Now... I suspect you're thinking 'AHA! old-passwords is on!'. Unfortunately it's not - I've disabled it in the configuration (explicitly set it to 0), made doubly sure I have an absolute reference to that configuration file and ensured the service isn't using the --old-passwords flag. The service was reset after each and every operation. So I went onto another system and generated the 328-bit hash on there, copying the hash over to the first MySQL instance. Unfortunately, that didn't work either (I did remember to FLUSH PRIVILEGES). The application error is: "'mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool [...snip...] Is there anything else I can try to get PHP to recognise MySQL as not using the 'old insecure authentication'? MySQL seems to be stuck in 'old-passwords' mode and I can't get it out of it.

• Exchange emails not delivering for one user

  - by Cylindric

  We have an Exchange infrastructure going through a migration from 2003 SP2 (call it ExOld) to 2010 (ExNew). All users are now on the new server, but mail is still being directed to ExOld until testing is complete. ExNew sends emails directly to the internet. For one particular user, emails don't seem to be being reliably delivered, but the odd thing is that it's not all emails. I can see external emails in his inbox. If I send an internal email it works fine. If I send an email from Gmail to him it doesn't get through. If I telnet from outside to ExOld I can send an email to him. If I telnet from outside to ExNew I can send an email to him. This is a transcript that results in a successful send: 220 ExOldName Microsoft ESMTP MAIL Service, Version: 6.0.3790.4675 ready at Mon, 22 Oct 2012 10:55:26 +0100 EHLO test.com 500 5.3.3 Unrecognized command EHLO test.com 250-ExOldFQDN Hello [MyTestExternalIp] 250-TURN 250-SIZE 250-ETRN 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-8bitmime 250-BINARYMIME 250-CHUNKING 250-VRFY 250-X-EXPS GSSAPI NTLM LOGIN 250-X-EXPS=LOGIN 250-AUTH GSSAPI NTLM LOGIN 250-AUTH=LOGIN 250-X-LINK2STATE 250-XEXCH50 250 OK MAIL FROM:[email protected] 250 2.1.0 [email protected] OK RCPT TO:[email protected] notify=success,failure 250 2.1.5 [email protected] DATA 354 Start mail input; end with .

• Start Chrome by command line, but adding some arguments to make it login into your Google account automatically

  - by jim

  Is there a way to start Chrome calling it from the command line (using Linux), but providing it some argument to make it login into some Google account automatically? I'm looking for something like google-chrome -account foo -pass bar that I can easily put in a bash script later. A little background: I have a laptop connected to my TV, which is currently using just a mouse for user interaction. There's no google account logged in by default, and that's the way I want to keep it, so my kids can't come across videos and pictures in google and youtube that they are not supposed to see (e.g.: adult content, or anything marked as not appropriate for kids by the google's safe search filters). The bad thing about this is that there are some music videos in youtube that requires you to be logged in to see, usually those we (the adults) used to sing when playing karaoke... as the only input available is a mouse, I'm looking for a way to start with my google account without having to type the whole thing usin the on-screen keyboard. You may think "Why you can't use the keyboard, if the laptop is right there?". Well, it's in a kind of uncomfortable position - too high for me without a chair or something, as it's right above the furniture in where the TV is located. Is there a way to make this scriptable? If not, do you know any other workaround? Note: using the remember me after logging off or alike options are discarded, as the safe-search chrome version must be always the default version to run.

• Recovering ZFS pool with errors on import.

  - by Sqeaky

  I have a machine that had some trouble with some bad RAM. After I diagnosed it and removed the offending stick of RAM, The ZFS pool in the machine was trying to access drives by using incorrect device names. I simply exported the pool and re-imported it to correct this. However I am now getting this error. The pool Storage no longer automatically mounts sqeaky@sqeaky-media-server:/$ sudo zpool status no pools available A regular import says its corrupt sqeaky@sqeaky-media-server:/$ sudo zpool import pool: Storage id: 13247750448079582452 state: UNAVAIL status: The pool is formatted using an older on-disk version. action: The pool cannot be imported due to damaged devices or data. config: Storage UNAVAIL insufficient replicas raidz1 UNAVAIL corrupted data 805066522130738790 ONLINE sdd3 ONLINE sda3 ONLINE sdc ONLINE A specific import says the vdev configuration is invalid sqeaky@sqeaky-media-server:/$ sudo zpool import Storage cannot import 'Storage': invalid vdev configuration I should have 4 devices in my ZFS pool: /dev/sda3 /dev/sdd3 /dev/sdc /dev/sdb I have no clue what 805066522130738790 is but I plan on investigating further. I am also trying to figure out how to use zdb to get more information about what the pool thinks is going on. For reference This was setup this way, because at the time this machine/pool was setup it needed certain Linux features and booting from ZFS wasn't yet supported in Linux. The partitions sda1 and sdd1 are in a raid 1 for the operating system and sdd2 and sda2 are in a raid1 for the swap. Any clue on how to recover this ZFS pool?

• Debian Wheezy (testing) df reported volume size

  - by TheRoadrunner

  I am a bit confused about the /dev/sda* references since I installed Wheezy instead of Squeeze on a testing box. fdisk -l returns: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000e9623 Device Boot Start End Blocks Id System /dev/sda1 * 2048 480278527 240138240 83 Linux /dev/sda2 480280574 488396799 4058113 5 Extended /dev/sda5 480280576 488396799 4058112 82 Linux swap / Solaris This seems correct. But df -h /dev/sda (and /dev/sda1 and /dev/sda2 and /dev/sda5) returns: Filesystem Size Used Avail Use% Mounted on udev 10M 0 10M 0% /dev The same happens with every entry under /dev/disk/by-id and /dev/disk/by-path. Only one of two entries under /dev/disk/by-uuid returns the correct volume size: df -h /dev/disk/by-uuid/cacdbad6-7e6b-4e80-84ba-e3c77ef48796 Filesystem Size Used Avail Use% Mounted on /dev/disk/by-uuid/cacdbad6-7e6b-4e80-84ba-e3c77ef48796 229G 22G 196G 11% / Contents of /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

Is this because Wheezy is in testing, and should it be reported as an error?

• Cannot access new folders created in my Apache2 document-root

  I have tried to create a new folder 'test' in my documentroot of my Apache2 installation, however, whenever I try and access it from a web-browser it gives me a 403 (forbidden) error. My virtualhosts file - <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName REMOVED DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride All AuthType Digest AuthName "documentroot" AuthDigestProvider file AuthUserFile /etc/apache2/htpasswd Require user REMOVED AllowOverride Indexes </Directory> <Directory /var/www/> Options FollowSymLinks Options -Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> <Directory /var/www/share/> Order Deny,Allow Allow from all Satisfy any </Directory> <Directory /var/www/REMOVED/> Order Deny,Allow Allow from all Satisfy any </Directory> <Directory /var/www/stream/> Order Deny,Allow Allow from all Satisfy any </Directory> <Directory /var/www/test> Order Deny,Allow Allow from all Satisfy any </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

If I copy folder 'rapidleech' to the name 'rapidleech1', it will let access 'rapidleech1', but no longer 'rapidleech', until I delete the copy. In my logs I found nothing logged in errors.log, and only that it delivered a 403 in access.log. All the appropriate users are members of www-data.

• How could I embed formatted XML source in WORD documents?

  - by eckes

  I'm writing a documentation with WORD that contains XML source code (whole files) as examples. The way I'm embedding the currently XML is quite cumbersome and doesn't seem to me as really maintainable: I'm finishing the editing of the document in WORD and create a PDF from it using Acrobat next, I open my XML files (2x input files, 2x generated output files) with IE and print them with the PDF printer supplied by Acrobat now, I open up Acrobat Pro and attach the four XML-PDF files to my original document The problem with that work flow for me is that it involves too much manual labor in order to get the documentation done. What I've tried up to now is not really satisfying for me: converting each XML to PDF and appending them like described above opening the XML files with SCiTE, copy as RTF and paste into Word playing around with the LaTeX packages minted, pygments and listings (I could write the docs with LaTeX too) but found some unsolvable problems in each of these packages I'm searching for a way that produces my documentation more automatic. For example embedding the XML files including formatting of IE (which I find quite readable). The files should be included by reference so that I don't have to paste the XML sources manually every time the XML changes.

• windows xp cannot access admin share

  - by barlop

  I have 3 systems. A,B,Compx all on xp. but comps A and B have an issue with Compx. Compx has network shares I can access. I can do \\compx and get some. But I cannot access the admin share c$ \\compx\c$ gives a login prompt, and I can't get any user/pass to work. I looked at permissions but don't see an issue. Nevertheless, I will describe what I see in the permissions. In the security tab of C, I have Administrators,creator owner,everyone,bob,system,users (6 things there) "creator owner" has nothing ticked, I can't seem to change that. If I tick so they all get ticked, and click apply, 2.5min and it's completed its opration and they all untick. Though this isn't the root of the problem. Since I get the same in the share I can access. In advanced, I see those 6 things, Administrators,creator owner,everyone,bob,system,users (6 things there) all "full control" all are "this folder, subfolders and files".. except creator owner, which is just subfolders and files only I look at the properties for the share I can see. looks the same, except in security..advanced, double clicking any of them the boxes are all ticked but greyed. That's not the problem though since I can access that share. So, I don't know what the problem is.

• What mobile phones are viable for a "nerdy" person? [closed]

  - by Blixt

  This community wiki is for determining a list of good mobile phone choices if you are "nerdy" (definition follows.) As a point of reference, the almost two years old N95 8GB will be used. Mostly because that's what I can most relate to since I've had it since it came out. Today, iPhone and other modern mobile phones really out-shine it in usability and interface. However, it still does everything I want it to do (and here's the definition of "nerdy"; modify as needed): Syncs contacts, calendar, tasks and mail in the background Can run multiple installable applications in the background (Google Maps with Latitude, for example) Good amount of space for music etc. Lets you develop your own little toy applications (Python; not to mention it can also run an Apache server with a public URL!) Tethering! Supports Flash (maybe not very important, but it has its uses) Has a manufacturer that believes in the nerdiness! (The people at Nokia Labs make lots of cool stuff and share early versions with the community and are generally open) A high resolution screen (at least 320x240) Special hardware features such as an accelerometer and GPS What's missing from the N95 8GB but still qualifies as good, "nerdy", qualities: 7.2 Mbit/s (or faster) internet through HSDPA or HSPA+. A good web browser that can do most of the stuff a desktop browser can (especially render sites properly and run JavaScript correctly) Touch (especially multi-touch) More special hardware features such as a compass Intuitive and fluent user interface (Shiny stuff) Ability to configure it to trust root certificates of my own choice A processor fast enough to run Quake 3! =)

• Same native and tagged vlan possible on Redhat?

  - by Chris Phillips

  Hi guys and gals, I'm looking at implementing a systems using a number of tagged and a native vlan connected to a server over a a/p bonded interface. The untagged vlan is for physical machine access, the tagged vlans are connected to bridges and then to QEMU VM's inside the machine. Hopefully this plan is fine, but I'm trying to implement a crippled version of this in a dev environment due to a lack of underlying network config in this location where I just have the same single vlan delivered to the machine on a tag AND plain. I'm nto clear if this is going to work (and that I should just be confident that it will work using different vlans) as I'm seeing odd things like a vm is arping out over the vlan out to the core switch, but the arp reply is coming back on the untagged interface. Now an ARP reply is unicast right? So it's a deliberate thing to send the ARP response on the untagged interface, and not a case that a broadcast response isn't being passed on the tagged side... i.e. there's some underlying logic pushing it that way. Something about the MACs somehow? This is on a CentOS 5.5 machine, vlan's from vconfig. (I've seen reference to the Linux mac-vlan project work, but that's not available here by default.) so 1) Should having the SAME vlan tagged and untagged work? 2) Will different tagged vlans to the untagged interface work nice and easily?
