• How do I turn a shared computer back into a shared media drive?

  - by Brian Green

  There is an external hard drive that is set up as a shared media device for a TV. I tried to hook up my the library on my desktop as a shared media drive to watch movies from my computer on the TV. It worked for a little bit but about 5 seconds after getting into my computer the tv went blank and I couldn't access the external hard drive any more. When I checked on my computer the Hard drive was no longer a shared media device but now it was a computer on the network. How do I fix this and turn it back into a shared media device so I can access it on the TV?

• Sharing VPN from XP to Linux virtual

  - by user55513

  Hi I will keep the question simple with few details, if more is needed tell me. Thanks. I am playing around with networking and virtualbox. So I have 2 virtual machines. One is windows xp and another has linux in it. Windows XP has 2 network cards. One for the internet and the other to connect to the linux computer. Linux has one 1 card and it can only access the internet passing through Windows XP. Internet works fine until I activate OpenVPN on Windows. When I turn on VPN, Linux has no access to it. How can I make linux use VPN too? I believe it has something to do with using the "route" command on XP to send VPN traffic to Linux but I was not able to figure it out how yet.

• 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.

• Updating AFP version on Windows Server 2003

  - by Niclas Lindqvist

  Hi, We have a couple of Macs, running Leopard and Snow Leopard in our otherwise pure Windows environment. We cannot get file names longer than 31 characters and some times the file permissions gets scrabbled (users can't delete their own folders or access files they usually access). This only occurs when connecting through AFP, We've tried with SMB but it's horribly slow when working with larger documents, so it's not an option. I somewhere read about AFP 3.0 being the answer. So my question is: Is there some way of updating my "AFP version" on Windows Server 2003, or does anyone have a different idea of what might help to resolve this situation?

• How to connect MySQL database of local server in NetBeans 7.0.1 ( windows)?

  - by diEcho

  Hello All, I am using NetBeans IDE 7.0.1 on Windows 7 very first time for my php. Actually in my company there is a local server ( 192.168.1.99) where all projects resides and we access phpmyadmin of that local server, Although I have added my project folders with NetBeans (this was also very hectic) but now I am having problem to connect database of my local server as I can see 192.168.1.99/phpmyadmin through my browser. I have set below value Server Host : localhost, Server port number : 3306, Administrator username : keshav Administrator password : ****** and when i click on connect, a popup error windows appears with below text Unable to connect to the MySQL server: org.netbeans.api.db.explorer.DatabaseException: org.netbeans.api.db.explorer.DatabaseException: java.sql.SQLException: Access denied for user 'keshav'@'localhost' (using password: YES). The server may not be running or your MySQL connection properties may not be set correctly. Do you want to edit your MySQL connection properties? Please help me out. Thanks

• oddities in interference of linux extened ACLs and 'regular' permissions

  - by abbot

  I've got some legacy code which checks that some file is read-only and readable only by it's owner, i.e. permissions set to 0400. I also need to give read-only access to this file to some other user on the system. I'm trying to set extended ACLs, but this changes 'regular' permission bits in a strange way also: $ ls -l hostkey.pem -r-------- 1 root root 0 Jun 7 23:34 hostkey.pem $ setfacl -m user:apache:r hostkey.pem $ getfacl hostkey.pem # file: hostkey.pem # owner: root # group: root user::r-- user:apache:r-- group::--- mask::r-- other::--- $ ls -l hostkey.pem -r--r-----+ 1 root root 0 Jun 7 23:34 hostkey.pem And after this the legacy code starts complaining that the file is group-readable (while it is actually not!) Is it possible to set the extended ACLs in such a way that some other user will also have read-only access, while the file will appear to have only 0400 'regular' permissions?

• Proper web server setup

  - by DMin

  I just got myself a slicehost basic slice to play around with so I can learn how to setup web-servers. I have Ubuntu 10.04.2 installed on the server. I was able to successfully get the server up and running from scratch, these were the things I did - following this tutorial. I know this is probably just a starters tutorial, so, I was wondering if you guys can tell me what you like to do while setting up production servers. These are the steps that were followed : Update and Upgrade Ubuntu sudo apt-get install apache2 php5-mysql libapache2-mod-php5 mysql-server Backup a copy of and edit apache2.conf Set : 'ServerTokens Full' to 'ServerTokens Prod''ServerSignature On' to 'ServerSignature Off' Backup php.ini and then Change “expose_php = On” to “expose_php = Off” Restart Apache Install Shorewall firewall Configure Shorewall to only accept HTTP and SSH connections(in the rules file) Enable shorewall on startup Add the website to the server : sudo usermod -g www-data root sudo chown -R www-data:www-data /var/www sudo chmod -R 775 /var/www I want make this CommunityWiki but can't seem to find the option to do it. Please feel free to add any feedback on the processes and things I am doing right/wrong. Much appriciated, thanks! :)

• Arch Linux: How to handle patches which only you will use?

  - by user12932

  I'm using freerdp together with xmonad and it has been giving me a lot of trouble. The super key (or "windows key") is my mod key in xmonad and it has been interfering with my freerdp usage rather annoyingly. Whenever I switched workspaces (or did anything else in xmonad involving the super key), windows (controlled by the freerdp instance in focus) registered a keypress as well. This event combined with the loss of focus got the super key stuck in windows indefinitely: the press of the keys d and r would first show my desktop, then open the run dialog (as if I was pressing the windows key constantly). I've tried several versions of freerdp, but all exhibited this annoying behavior. So I resorted to patching freerdp myself to just ignore the left super key on my keyboard. I love free software for a lot of reasons (especially the ability to alter things like this myself), however I still find it annoying to patch and rebuild freerdp on all version (and dependency) changes. How do you deal with situations like this? Is there even a "right way" to resolve this issue?

• Does the upload file INPUT HTML element give any personal information away?

  - by Senseful

  I'm wondering what personal information the file input (<input type="file">) element gives the website. I noticed that it does show the file name and the website does seem to have access to it. What about the file's path? If the file is located in My Documents, they could find out the user name via the path (e.g. C:\Documents and Settings\Bob\My Documents) which many times is the actual user's name that is using the website. What information do most modern browsers allow the website to access when a user uses the file input element? Could JavaScript somehow be used to gain more information? What about when plugins (such as Flash or Java) implement file uploading?

• Have Ubuntu 9.10 desktop, just got Macbook Pro. Share over Samba, NFS, other?

  - by miamisoftware

  Hi everyone. As the title says, I have and love my Ubuntu 9.10 desktop (use it for programming). Just got a Macbook Pro (Snow Leopard) and stuff like Documents, etc, trying to figure out easiest way to share my Ubuntu desktop with my Macbook Pro. Should I use Samba or NFS and is it easy to configure one (or something else) for only in network access (192.168.1.x). It took me about 2 days to find/setup Macfuse and Macfusion for sshfs to the Fedora web server and I'm hoping there's something much easier for this in network access. But if it requires or is suggested I go ssh, I can do that. Are there any security problems with either Samba or NFS - don't know much about AFP-Apple protocol so I've not brought it up. Thanks in advance.

• Windows Server 2003 (as workstation) unable to write to Samba fileshares

  - by remyhorton

  Setup is a Samba fileserver under Linux, which i am trying to access from a Windows Server 2003 box which has been reconfigured as a workstation. I can log onto the fileshares and can copy/delete files, but trying to open a file then write to it fails. Renaming files also fails with an error about requiring a filename. Drag/dropping files onto Xemacs gives me a message about copying from the network zone, and once open the file is read-only. Any ideas of what is wrong? I suspect it is a miscommunication of security details, as folder security options are all unchecked (checking them has no effect). I know it is not a problem with Samba itself, as Window2000, WindowsXP, and Nautulas (under Linux) can all access/edit fileshare files fine using the same userid/password. I am not using domain logins.

• how do I set up a virtual host (it's not working, and I've done everything right)

• IIS 7 throws 401 responses on application whose physical directory has been shared

  - by tonyellard

  I have an IIS 7, Windows Server 2008 R2 box with a relatively fresh install. I've deployed a .NET 2.0 application using windows autentication to the server, and from the default website, added it as an application. I updated the IIS authentication to enable Windows Authentication. When I went to share out the physical directory for the application so that a developer could deploy updates, the users began to receive 401 errors. I can reliably recreate the issue by sharing out the directory of any newly created application. The IIS user has the necessary read/write access to the directory. What do I need to do to keep web users from receiving 401's while at the same time allowing this developer to have access to the physical directory for deployments? Thanks in advance!

• Sarg report error

  - by amyassin

  I have a proxy server that runs Ubuntu Server 11.10, Squid 2.7.STABLE9. I installed sarg (version 2.3.1 Sep-18-2010) to generate reports using the ordinary apt-get install, and added a cron job to generate a report of the day every 5 minutes (that will overwrite the 5-minutes-older one): */5 * * * * /root/proxy_report.sh And the content of /root/proxy_report.sh is: #!/bin/bash /usr/bin/sarg -nd `date +"%d/%m/%Y"` > /dev/null 2>&1 And I added another cron job to generate a full report every hour at :32 (not to collide with the 5 minutes job): */32 * * * * /root/proxy_report_full.sh And the content of /root/proxy_report_full.sh is : #!/bin/bash /usr/bin/sarg -n > /dev/null 2>&1 And I added a small script to remove the yesterday full report (the full report that ends in yesterday that won't be overwritten by the new today full report) in /etc/rc.local to run at startup: /usr/bin/rm_yesterday.sh &>> /var/log/rm_yesterday Where /usr/bin/rm_yesterday.sh: #!/bin/bash find /var/www/sarg/ | grep `date -d Apr1 +"%Y%b%d"`-* | grep -v `date +"%Y%b%d"` | xargs rm -rf * Apr1 is the starting date of the proxy... ** I've placed it in /usr/bin to be mounted early at startup... That arrangement went OK for about a month and a half, except for one time I noticed some errors and reports wasn't generated, and fixed that by making an offset (the two minutes in 32 of the second cron job). However, it then started not to generate reports anymore. By manually trying to generate it it gives the following error: root@proxy-server:~# sarg -n SARG: getword_atoll loop detected after 3 bytes. SARG: Line="154 192.168.10.40 TCP_MISS/200 39 CONNECT www.google.com" SARG: Record="154 192.168.10.40 TCP_MISS/200 39 CONNECT www.google.com" SARG: searching for 'x2f' SARG: getword backtrace: SARG: 1:sarg() [0x8050a4a] SARG: 2:sarg() [0x8050c8b] SARG: 3:sarg() [0x804fc2e] SARG: 4:/lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xf3) [0x129113] SARG: 5:sarg() [0x80501c9] SARG: Maybe you have a broken date in your /var/log/squid/access.log file When I looked to /var/log/squid/ folder, I noticed that it contains some rotated logs: root@proxy-server:~# ls /var/log/squid/ access.log access.log.1 cache.log cache.log.1 store.log store.log.1 So maybe sarg installed logrotate with it? Or it comes with the standard Ubuntu? I don't remember I installed it manuallly. The question is: What could've gone wrong? Does it have something to do with rotating the log? How can I trace the error and start generating reports again?

• How to fight off against a government's internet censorship?

  - by Fellknight

  I live in a country where the left-wing totalitarian regime that it's our government has begun the procedures (legal and physical) to restrict the internet access of it's citizens following the footsteps of China and Cuba. I believe that free access to information is a human right and should not be under any circumstances restricted or sanctioned, i don't want to live in country that does otherwise. Unfortunately leaving for good for the time being it's not an alternative. What I (and all the people that think like me) need to know is; if there are ways of bypassing the possible protections that will be implemented soon?, like the Chinese do . I'm afraid that even proxys might not suffice in the long term since our ISP will be implementing the regulation. Any information or explanation on this will be deeply appreciate it.

• Securing a persistent reverse SSH connection for management

  - by bVector

  I am deploying demo Ubuntu 10.04 LTS servers in environments I do not control and would like to have an easy and secure way to administer these machines without having to have the destination firewall forward port 22 for SSH access. I've found a few guides to do this with reverse port (e.g. howtoforge reverse ssh tunneling guide) but I'm concerned with security of the stored ssh credentials required for the tunnel to be opened automatically. If the machine is compromised (primary concern is physical access to the machine is out of my control) how can I stop someone from using the stored credentials to poke around in the reverse ssh tunnel target machine? Is it possible to secure this setup, or would you suggest an alternate method?

• Is it possible to change error messages for users connecting to network printers?

  - by eric.s

  We are cleaning up our print server (Win XP). To test that printers are no longer really there we have set up some tests. These tests have left us with 176 questionable printers. We have now set Print access to Everyone to Deny. Testing shows this gives the user a 5 Access is denied. message. We would like to change this message for the user, so when they call our workstudy's who answer the phone do not interpret this as a computer rights management issue and can route the call properly. Is it possible? Is this error number system wide, or just for printing errors? If it's not a system wide error where might the string for this error be?

• lighttpd silently stops logging

  - by Max Cantor

  I'm on a Slicehost 256MB VPS with Ubuntu 9.04 (Jaunty). lighttpd is the only web server process running; it listens on port 80. My lighttpd.conf can be found here. I'm using Ubuntu's default logrotate setup for lighty. At seemingly random times, lighttpd will stop logging. It is not correlated with log rotation--that is, the errors do not occur when logrotate kicks in. What happens is, I will verify that the server is serving files by hitting a URL with my browser, and I will verify that it is not logging by checking access.log and seeing that the GET request I just made is not there. Using init.d to restart the process starts logging again, without truncating or rotating the log file. That is, new requests will be logged at the end of the existing access.log file. There are no cron jobs running on this box. Any ideas?

• iptables question

  - by RubyFreak

  i have a small network, with one valid IP and a firewall with 3 network interfaces (LAN, WAN, DMZ). I want to enable PAT on this valid IP to redirect http traffic to a server in my DMZ. (done) I want to enable MASQ on this ip from traffic that comes from my LAN (done) I want from my LAN as well to access my http server at DMZ. (partially) Question: in the above scenario, i cannot from my LAN, to access my http server in the DMZ, since it has the IP used by the MASQ (the only valid ip that i have). What would be the best option to solve this problem? network interfaces: eth0 (WAN) eth1 (DMZ) eth2 (LAN) /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE /sbin/iptables -A FORWARD --o eth1 -d 2.2.2.2 -p tcp --dport 80 -j ACCEPT /sbin/iptables -t nat -A PREROUTING -i eth0 -d 1.1.1.1 -p tcp --dport 80 -j DNAT --to 2.2.2.2 /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT /sbin/iptables -A FORWARD -i eth2 -o eth0 -j ACCEPT

  I have a SQL Server 2008 instance. I have configured filestream access properly, and use it from one column on one table in one of my databases. However, I cannot access the UNC share for the filestream data. I have tried browsing to it as well as trying to open specific files and I get errors both ways. I am running SQL Server 2008 enterprise on a Windows 7 workstation running on the domain. I've tried running the sql server service as a local user, then as network admin.

• Port forwarding not working?

  - by rphello101

  I'm trying to set up an Apache Server to be accessed publicly. I'm using a Netgear R4500 router hooked up to a Motorola SB6121 modem. I can access my server on my computer by typing in my IP address. After following the instructions to forward port 80 so I can access the server from other computers, it does not work (see image). I get "This webpage is not available". I am forwarding to the IP address of my computer. Using this Network Port Scanner Tool, it says "80/tcp filtered http", which, as I understand it, means forwarding did not work correctly. In my Apache httpd file, I have: ServerName 192.168.1.13:80 and Listen 192.168.1.13:80 Anyone know what's wrong or have something I can try? click to enlarge

• Signal strength and Speed of wireless network

  - by Tim

  As shown by Lenovo Access Connections on my Windows 7, the wireless network I am using has a speed of 54.0Mbps but a signal strength of 88%. I am using WinSCP with unlimited speed to download files. WinSCP shows that the speed fluctuates between 100 and 120KiB/s. I was wondering what are the difference between the two speeds from Lenovo Access Connections and WinSCP? How can I tell the actual speed performance, for example, from the above measurements: speeds and the signal strength mentioned in the two places. Thanks and regards!

• OWA draft folder doesn't sync up wint Outlook 2007 (when using Citrix)

  - by George

  I have a user logging in to Citrix Server (on Windows 2003) to use Outlook 2007. In OWA, he sees all his drafts in Draft Folder and can easily access them, but when he is Citrix, he can see the folder, but not the messages. I had him check Normal and Favorite Folders under View - Navigation Pane as well as execute outlook /cleanviews to no help. I should also clarify, we host exchange locally and it syncs up with Outlook 2007 in Citrix. Remote users use either OWA for access or login to Citrix and use Outlook 2007. In his case ALL folders appear in Outlook 2007, but draft folder doesn't show any saved messages, even though in OWA messages are there and he can edit, delete and send them. Please, help! Thanks!!!
