• What is the best OS for a server hosting a simple Ruby on Rails based pastebin

  - by Koning Baard XIV

  I have created a simple pastebin in Ruby on Rails and Python. I want to host it in an intranet and it will have like about 1000 users. I want to use one Apache server with a cluster of Mongrel servers. The server itself is a 2 GHz Intel Centrino with 2 GB RAM. What do you think is the best OS to host this? I thought about Damn Small Linux or a custom LFS system. Ubuntu servers come with loads of stuff I don't need. Maybe there are some better OSes? It must be capable of: Running Apache Running Ruby Running Python Running Mongrel with Ruby on Rails SSH Can anyone reccomend me one? Thanks. PS: I am not going to run Windows Server or Mac OS X Server (Mac's are expensive).

• VisualAssert Testing in C++, Loading a test fixture.

  - by C_Bevan

  Good day, I am learning Testing in Visual Studio C++ and I have several tutorials which I have followed. I am trying to load a test fixture. I have tried to put the test .cpp file in many different places but it will still not pick up on it when I click on "Run Tests" or "Run Tests without debugging" In the tutorials I found, they seemed to load into the Test Explorer automatically, but in mine is an icon with a X + (PROJECTNAME).EXE and when I hoover over it I get the process exited without registering with the agent... this is due to the model not containing any test fixtures... How can I load my tests into the Test Explorer...or register them with my project... I've tried right click and "Add Fixture...".... but that just starts a new test file and I have the same problem. Anybody know how I solve this issue?

• Squid traffic tunneled through VPN

  - by NerdyNick

  So what I'm trying to do is have a Squid Proxy run on 1 machine along side a VPN connection. What I want to happen is all traffic running though the Squad Proxy would run though the VPN for its outbound. ie Desktop - (Squid Proxy - VPN) The goal is to allow my desktop selective tunneling through the VPN. So that Instant Messaging and the like that do not need to run through the VPN can go through my normal traffic. Typically I would go though a SSH Proxy but currently am forced to use VPN to gain entry into the office, and a Squid proxy seemed like it might work out the easiest for what I am needing. EDIT Realize I forgot to actually state what problem I'm running into. I have the Squid setup and verified it works, but once I connect to the VPN. All requests to Squid get accepted but Squid is unable to make the request over the VPN. So the client ends up just sitting there.

• Repartition Ubuntu by command line?

  - by DisgruntledGoat

  On my server the filesystem includes these partitions: Filesystem Size Used Avail Use% Mounted on /dev/sda6 4.6G 929M 3.5G 21% / /dev/sda5 76M 20M 53M 27% /boot /dev/sda8 449G 199M 426G 1% /home /dev/sda7 4.6G 4.4G 0 100% /var (Output from df -ah) I'm storing the web sites and databases under /var and as you can see it's got full. The /home folder just has basic user directories and nothing else so I'd like to repartition the server so that /dev/sda8 is about 5GB, with the rest going to dev/sda7. What's the easiest way to do this via command line (i.e. SSH)?

• Ubuntu server - Problem of routing

  - by Max

  Hi, I have setup a Ubuntu server with Ubuntu Enterprise Cloud. The server is connected to a private LAN with DHCP and Internet access (via a gateway). At first, the server was working fine. It can ping the internet. It can also ping other machine inside LAN. The problem happened after i let the machine idle for more than 1 hour. When I want to use the machine again, I can't ping the internet anymore. I can only ping the machine inside LAN. I try to ping the server from another machine and it's working. Then, i ssh into that server from another machine, and I found that I can ping the internet from that server. It seems that there are some problems in the routing table of this server. Can anyone help me on this? Thank you. Max

• $RYSNC_PASSWORD not being read/responded-to correctly (Snow Leopard)

  - by warren

  Ignoring the security issues, I have the following script that synchronizes my music library from my MacBook Pro (running Snow Leopard) to the file store (CentOS 4) on my network: rsync -rav --progress --partial -e "ssh" ~/Music/iTunes/* user@scramasax:~/music/iTunes-scissor:~ When I try to use either a password provided on the command-line (), in a password file (--password-file), or in the environment variable RSYNC_PASSWORD, the login still goes interactive, requiring me to type my password again. I will be moving to pre-shared keys on my network, but in situations where that is not possible, such as rsync'ing files to a webserver, being able to successfully embed the password in the script would be very helpful.

• POST with HTTPBuilder -> NullPointerException?

• How do I set permissions structure for multiple users editing multiple sites in /var/www on Ubuntu 9

  - by Michael T. Smith

  I'm setting up an Ubuntu server that will have 3 or 4 VirtualHosts that I want users to be able to work in (add new files, edit old files, etc.). I currently plan on storing the sites in /var/www but wouldn't be opposed to moving it. I know how to add new users, I know how to add new groups. I'm unsure of the best way to handle users being only able to edit some sites. I read over the answers here in this question, so I was thinking I could setup a group and add users to that group, but then they'd all have essentially the same permissions. Am I just going to have to assign each user specific permissions? Or is there a better way of handling this? Added: I should also note, that I'll have each user login in via SSH/sFTP. The users would never need to do anything else on the server.

• Issues with SSL key on CentOS

• Is my form password being passed in clear text?

  - by liinkas

  This is what my browser sent, when logging into some site: POST http://www.some.site/login.php HTTP/1.0 User-Agent: Opera/8.26 (X2000; Linux i686; Z; en) Host: www.some.site Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en-US,en;q=0.9 Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.some.site/ Proxy-Connection: close Content-Length: 123 Content-Type: application/x-www-form-urlencoded lots_of_stuff=here&e2ad811=my_login_name&e327696=my_password&lots_of_stuff=here Can I state that anyone can sniff my login name and password for that site? Maybe just on my LAN? If so (even only on LAN ) then I'm shocked. I thought using <input type="password"> did something more than make all characters look like ' * ' p.s. If it matters I played with netcat (on linux) and made connection browser <= netcat (loged here) <= proxy <= remote_site

• Simple web-frontend for remote svn administration?

  - by Stefan Lasiewski

  We run a SVN repository. Some of our more advanced users need to be able to perform some SVN administration without relying on the system administrator. They need to be able to do things like create SVN repositories, delete SVN repositories,, and perform commands like 'svnadmin dump' and 'svnadmin load'. We'd like to avoid SSH access on these FreeBSD machines, and would rather provide a service interface through a Web UI. I'm looking for a simple script (or a small number of scripts) which use Perl or PHP. I found svnadmin or svnadmin.pl, but was hoping to find something with a larger user community or which has been recommended by others. It looks like Trac allows SVN administration, but comes with may more features then we need.

• How can I find a computer on my network that is doing mass mailings?

  - by Alex Ciarlill

  I was notified by my isp that one of my machines is sending out spam. This happened about 3 months ago on windows machine running cygwin that was hacked due to an SSH vuln. The hackers setup IIS and SMTP. I cleared out the machine and all the services are disabled so I think that machine is okay I am wondering if there is any other way to identify which machine it could be coming from? The ISP has NO useful information such as source port, destination port, destination IP... nothing. I am running DD-WRT on my router, Windows 7 PC and a Windows XP PC.

• Trying to script rsync using pam_exec

  - by Ricky-Rose

  I'm trying to write a bash script that will execute rsync when called by pam_exec. I've tried a couple different ways, and I'm not sure what I'm doing wrong. When I try to run the script at login by adding session optional pam_exec.so /usr/bin/local/sync.sh to my sshd file, it gives me an exit code of 12. if I log in and then manually run my script, it allows me to connect to the remote server, and it lists my files, but it doesn't actually sync anything. I have tried the code below using buth $USER and $PAM_USER. $PAM_USER doesn't work at all. #!/bin/sh rsync -azv -e ssh $USER@remote_server:/home/html/$USER/ /home/html/$USER

• Nginx/FPM/PHP all php files say 'File not found.'

  - by Boon

  i just installed nginx 1.1.13 and php 5.4.0 on a centos 5.8 final 64bit machine. Nginx and PHP/Fpm are running, and I can run php scripts via ssh command line, but in the browser I keep getting 'File not found.' errors on all my PHP files. This is how I have my nginx.conf handle PHP scripts: location ~ \.php$ { root /opt/nginx/html; fastcgi_pass unix:/tmp/fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /opt/nginx/html$fastcgi_script_name; include fastcgi_params; } This is a direct copy/paste from my other servers, where it works fine with this setup (but they run older versions of php/fpm). Why am I getting those errors?

• Robots Crawling Across Namespace?

  I migrated site from one domain to another. Also placed permanent redirection on old account. My stats logs are capturing this: Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) /libro_metaboforte_chap5.php/members/members/file_chap6.php I placed this on robots which wasn't present at time of migration.

• Resolving real IP address out of a dynamic dns address

  - by stavnir

  I recently opened a dynamic dns user (at no-ip for that matter..) for my own personal needs and especially for ssh-ing my computer whenever I need to, without knowing it's static IP. My questions are: Am I misusing the concept of dynamic dns? Are there more appropriate methods to do what I want to do? If not, how do I resolve my router's real ip address? Firefox somehow manages to do so, nslookup and other similar commands only resolve the ip of the ddns server (e.g. no-ip.org). Trying to figure this mystery with wireshark failed miserably ;)

• What tangible security are gained by blocking all but a few outgoing ports in a firewall

  - by Frankie Dintino

  Our current hardware firewall allows for blocking incoming and outgoing ports. We have two possibilities: Block certain troublesome ports (unsecured smtp, bittorrent, etc.) Block all but a few approved ports (http, https, ssh, imap-ssl, etc.) I see several downsides with option 2. Occasionally web servers are hosted on non-standard ports and we would have to deal with the resulting issues. Also, there is nothing preventing a malicious or unwanted service from being hosted on port 80, for instance. What are are the upsides?

• How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

  - by moogeek

  Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!
