• dead man's switch for remote networking interventions

  - by ascobol

  Hi, As I'm going to change the network configuration of a remote server, I was thinking of some security mechanisms to protect me from accidentally loosing control on the server. The level-0 protection I'm using is a scheduled system reboot: # at now+x minutes > reboot > ctrl+D where x is the delay before reboot. While this works relatevly well for very simple tasks like playing with iptables this method has at least two drawbacks: It's not very reactive, ie a connectivity problem should be detected automatically if for example an automatic remote ssh command fails does not work anymore for x seconds. It can obviously not work if one need to modify some configuration files and then reboot to test the changes. Are you guys using some tool for the second point ? I would love to have something able to revert the system configuration in a previously known stable state if I can't join the server X minutes after reboot. Thanks!

• OpenVPN Push DNS Not Working Correctly On Windows

  - by woodsbw

  I currently have OpenVPN server setup on an Ubuntu machine, as well as DNSMasq. I am wanting to push DNS to the client (road warrior setup.) I had the push "dhcp-option DNS x.x.x.x" where x.x.x.x was an open OpenDNS server, for testing, and everything was working when I connected from my Windows client But now that I have DNSMasq setup, and I changed the "dhcp-option DNS x.x.x.x" to the DNSMasq server, but when they client connects it still receives the old, OpenDNS DNS server IP. I'm at a bit of a loss here, I have tried flushing DNS on the client, rebooting the server, and I even grep'd the entire server to see if the OpenDNS IP was in some other config I was missing...it wasn't. One other note, when connect to the VPN and explicitly run nslookup against against the DNSMasq IP, the addresses resolve correctly, so it isn't a DNSMasq issue.

• site timing out when under heavy load

  - by naunu

  My client sends out eblasts at 8am monday/wed/friday. Between 8:15-8:45 the site becomes extremely slow and many users sessions timeout. My setup: Mediatemple VE 2gb dedicated ram (3 burst) Ubuntu 9.10 Apache2-mpm-worker PHP5.3-fcgi MySQL 5 I recently tried to remedy the problem by switching from apache2-mpm-prefork to mpm-worker, but am still having the same issues. My apache settings are: Timeout 100 KeepAlive On MaxKeepAliveRequests 100 <IfModule mpm_worker_module> StartServers 12 MinSpareThreads 25 MaxSpareThreads 96 ThreadLimit 96 ThreadsPerChild 25 MaxClients 225 MaxRequestsPerChild 0 </IfModule> The site is only getting ~10,000 page views during the 8am-9am hour, which I dont think should be stressing the server too badly. Maybe it is an error with the PHP settings, or bandwidth per unit time, or the site outgrew the server? Any suggestions would be very helpful - as you can see i've given it a good go before looking for help (installed mpm-worker). Also, can anyone suggest to me some free load testing software, or a tutorial on mod_status? Thank you

• download speed is fast but transfer rate is slow

  - by Ieyasu Sawada

  I've just changed ISP and I'm pretty disappointed with the transfer rate. My previous connection has a download speed of 1.08 Mb/s as seen from this site: http://speedtest.net and the download transfer rate is about 100kb/s for sites that doesn't limit their bandwidth. Now my connection has about 2Mb/s download speed but the transfer rate is dancing from 20-50kb/s . I was expecting a speed much higher than this because of the download speed that I'm getting when I'm testing. The question is what's the difference between transfer rate and download speed, is it normal to have a high download speed but low transfer rate, should the download speed be proportional to the transfer rate?

• Internet wireless connected with limited access, windows vista

  - by r0ca

  I had some malware in my computer so I did a bit of manual work to remove it including resetting TCP/IP. Now the malware is gone. I can see my home wireless network and I can get connected to it but when connected I get the Internet wireless connected with limited access message. When I go to the IE I cannot browse. When I tried to ping 192.168.1.1 I got an Error Code 1231 Unconnected Network Problem. I have deactivated my Windows firewall as I thought it could be hyperactive security. Still no luck. I have Norton but it is not active, I have also Avast and AVG installed but they are not active. Any ideas?

• When did Red Hat start shipping PHP 5.3 with 5.x?!?

  - by Jason

  Okay this is a PSA more than a question because I know the answer: January 13, 2011. See: https://rhn.redhat.com/errata/RHEA-2011-0069.html Colour me surprised though, didn't hear anything about in the blogosphere until I got a Security Errata notice today. I have been using the REMI repo for this in the past but will switch over to the Red Hat blessed PHP 5.3. Don't down-vote me bro! I'll select as the best answer the source that broke the news first (other than Red Hat of course). People have wanted this for so long I'm just amazed that it's finally happened!

• windows firewall and network location switch after establishing a vpn connection

  - by Konrads

  Hello, I am looking for a reasonable solution for network location switching after VPN connection is established for Windows 7. The scenario is as follows: For location public (employee plugging in his laptop in hotel, public wi-fi,etc) all inbound connections are restricted, only outbound VPN + www is enabled. Employee then initiates a VPN connection, VPN pushes routes to 10.0.0.0/8 subnet Now I would like to have lax security rules for traffic from/to 10.0.0.0/8 that comes through the VPN interface, while still protecting the laptop from traffic that comes via uplink interface as if it was private. How to achieve this switching and duality? One option I see is switching to IPSec...

• Reputable web based ssh client? [closed]

  - by Doug T.

  I'm connected to a coffee shop's wireless network right now, and I suspected I'd be able to use my laptop and ssh somewhere. Unlucky me they seem to be blocking everything but web traffic (my testing seems to show everything but port 80 is working, can't ping, ftp, etc). I googled "web based ssh clients" however I have reservations about entering my login credentials on any Joe Schmoe's web app. I was wondering if anyone has had any experience with any reputable web based ssh clients? If so could you please point me at one that I could trust?

• What is the difference between "su --command" and "su --session-command"?

  - by oliver

  Running # su - oliver --command bash gives a shell but also prints the warning bash: no job control in this shell, and indeed Ctrl+Z and fg/bg don't work in that shell. Running # su - oliver --session-command bash gives a shell without printing the warning, and job control indeed works. The suggestion to use --session-command comes from Starting a shell from scripts using su results in "no job control in this shell" which states "[a security fix for su] changed the behavior of the -c option and disables job control inside the called shell". But I still don't quite understand this. When should one use --command and when should one use --session-command? Is --command (aka -c) more secure? Or should one always use --session-command, and --command is just left in for backwards compatibility? FWIW, I'm using RHEL 6.4.

• Python server does not excecute PHP script: permission denied

  - by krisvandenbergh

  I am trying to execute a PHP file through a Python server. However, I get the following error: File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/CGIHTTPServer.py", line 255, in run_cgi os.execve(scriptfile, args, os.environ) OSError: [Errno 13] Permission denied The python server is running though. What have I done so far? Chmod'ed recursively all directories to (chmod -R a+x) (I know this is not secure but its just for testing purposes) for both Python installation directories and my scripts. Tried to find out if python server is running as root through ps aux grep py I am out of ideas. What could be going wrong else? Thanks for the feedback.

• Visual Query Builder

  - by johnnyArt

  If been using "dbForge Query Builder" lately and I'm gotten used to the ease of building and testing a query, specially for those complex ones with inner joins, aliases and multiple conditionals. The expiry date of the trial is about to come, and while wanting to remain on the legal side for this I'd rather not pay the 50USD it costs (although I must say it's pretty cheap for what it does). So my question would be: Are there any free alternatives to replace this visual query builder? I've failed to find any and fear that my only two options are paying for it, or going to the dark side.

• Web Deploy to IIS7 fails with 401 (Unauthorized)

  - by Trex

  we have IIS7 running on Windows Web Server 2008 R2 and it's set up to support Web Deploy. It worked fine when we used the default Administrator account. We recently disabled this account (for security reasons) and are now trying to deploy using another account which is member of the Administrators group, but the deploy fails with 401 (Unauthorized). More specifically, it says: Connected to '<IP>' using Web Deployment Agent Service, but could not authorize. Make sure you are an admin on '<IP>'. The remote server returned an error: (401) Unauthorized. Anybody has any ideas why this is happening? Thanks. Trex

• Problems enabling BitLocker on Windows 7 enterprise

  - by ericl42

  I had BitLocker turned on originally when I loaded the computer but had to turn it off to do some testing. I recently tried to turn it back on and I continue to get the following error: Blockquote A required TPM measurement is missing. If there is a bootable CD or DVD in your computer, remove it, restart the computer, and turn on BitLocker again. If the problem persists, ensure the master boot record is up to date. Blockquote I have verified that there is nothing in the DVD tray and that the laptop is not docked. I have also verified that TPM is running and I have no problems enabling BitLocker on a flash drive. I think it's a problem with my MBR since I am dual booting into Fedora as well but I am not sure how to fix it. (even though it did work a few months ago while I was also dual booted) Thank you for the help.

• Good default for XDG_RUNTIME_DIR?

  - by cadrian

  The XDG Base Directory Specification is a very interesting spec for user directories. It also provides good default values, except for XDG_RUNTIME_DIR. Now I am writing a software that needs to create named pipes. It is a per-user client-server framework (there is a FIFO for the server and a FIFO per client). If XDG_RUNTIME_DIR is not defined, I am currently using a per-user subdirectory in /tmp — but it does not ensure all the specified conditions (viz. the paragraph starting with "The lifetime of the directory MUST be bound to the user being logged in…") Is /tmp/myserver-$USER good enough? Edit I saw elsewhere a few suggestions: . is quite unsatisfactory (at least because it is not an absolute path). I also saw /var/run/user/$USER — not bad, but that directory does not exist (at least on my box running a Debian testing)

• Choosing between cloud (Cloudfoundry ) and virtual servers - for developers

  - by Mike Z

  I just came across some articles on how to setup your own cloud using Cloudfoundry and Ubuntu, this got me thinking, choosing our infrastructure, if we want to use our own servers what's the advantage of cloud on virtual servers vs just using virtual servers, VPN? If we now develop for the cloud later if we need help we can quickly move on to a cloud provider, but other than that what's the advantage and disadvantage of private cloud in these areas? speed of development, testing, deployment server management security having an extra layer (cloud) will that have a hit on server performance, how big? any other advantage/disadvantage?

• Is there a free-embedded SSH solution ?

  - by ereOn

  Hi, I'm working for an important company which has some severe network policies. I'd like to connect from my work, to my home linux server (mainly because it allows me to monitor my home-automated installation, but that's off-topic) but of course, any ssh connection (tcp port 22) to an external site is blocked. While I understand why this is done (to avoid ssh tunnels I guess), I really need to have some access to my box. (Well, "need" might be exagerated, but that would be nice ;) Do you know any web-based solution that I could install on my home linux server that would give me some pseudo-terminal (served using https) embedded in a web page ? I'm not necessarily looking for something graphical: a simple web-embedded ssh console would do the trick. Or do you guys see any other solution that wouldn't compromise network security ? Thank you very much for your solutions/advices.

• Win 2008 single server development environment (architecture)

  - by Tommy Jakobsen

  I have a few questions about a test development environment that I’m setting up on this server: Intel Core i7-920 Quadcode incl. Hyper Threading 8 GB DDR3 RAM 2x 750 GB SATA-II (probably software RAID 1) The server is going to support max 5 users, maybe 10 when stressed. I was hoping that I could run all the following products on the same server: Windows Server 2008 R2 x64 w/ IIS SQL Server 2008 x64 (R2 when released) Team Foundation Server 2010 Sharepoint Foundation 2010 I know this sounds overkill, but remember that this is for development purpose and testing. This is not a production environment. My question if this will be possible at all? Should I run it all on one Windows 2008 installation, or should I run it in multiple virtual environments using Hyper-V? What do you think?

• IPSec policies on Mac OSX

  - by Helder

  Is there a way to configure IPSec policies on a Mac OSX, in a similar way to what you can do in Windows, with "Connection Security Rules"? I need to implement a service that will use an IPSec tunnel, and I might have to provide it to Macs as well. As I don't have access to a Mac, I've done some reading, and it seems that there is something called "racoon" that handles IPSec. Can anyone confirm this? Further, we will need to use certificates for authenticating the IPsec tunnel as well (as opposed to pre-shared keys). Can anyone confirm that this is also possible from a Mac OSX? Thank you!

• Ruby, Rails & MySQL parity between Mac Client (10.6) & XServe (10.5)

  - by Meltemi

  We're setting up a RoR setup with Development on Mac OS X Client (10.6.3) and then using a Mac OS X Server (10.5.8) for testing and eventually deployment. I'd like to get as many systems in sync on these machines as possible. Wondering if there are any pitfalls. I seem to understand what's necessary under Client but Server has some hardwired stuff that I want to make sure doesn't break...or is updated correctly. Currently installed on both machines we have: OS X Client (10.6.3): Ruby 1.8.7 Rails 2.3.5 MySQL (not installed yet) OS X Server (10.5.8): Ruby 1.8.6 Rails 2.3.5 MySQL Ver 14.12 Distrib 5.0.82 Any suggestions...Ideally from someone who's done this on Leopard Server as well but I'll listen to general tips & proceedures

• Should a database server be in a different VM instance as an application?

  - by orokusaki

  I'm setting up a database server as a separate VM in my server so that I can control resources, and make backups of just that instance. I own a server that will reside in a colo soon. Is this the best way to approach my DB regarding scalability? Are there any security concerns? Do I listen at localhost still, even though it's a separate instance? And, is there any benefit to running your DB (PostgreSQL in my case) in the same machine as your application (web based SAAS application in my case)?

• Strange request - http://66.196.81.202/error/vote

  - by mplungjan

  Hi a friend of mine is asking about the request which can for example be found here: http://www.geoidee.ch/geodata/geoserver-2.0.0/logs/2010_11_23.request.log His original message: On a couple of hundred web sites worldwide, one of the 50 most popular "File not found" error 404 is caused by the following request: "GET http://66.196.81.202/error/vote HTTP/1.0" It originates from a user agent that purports to be an iPhone. The two requests that hit my servers appeared to originate near Frankfort, Germany. The IP address in the request is part of Yahoo although I doubt that Yahoo had any intentional part. fe1.buzz.vip.re1.yahoo.com The HTTP request has a host header 66.196.81.202 and a X-Forwarded-For of 96.6.99.16 and my IP address I expected to be able to do a Google search and find some kind of security bulletin on it, but I found nothing. It could just be that my search skills are deficient. Thanks for any pointers to what this could be

• CentOS 6.5 proxy bypass/no_proxy not working

  - by Naruto Uzumaki

  I am running CentOS 6.5 on my desktop. I've set the Network Proxy using the network proxy application provided under Preferences. I've also set the following exceptions: localhost,127.0.0.0/8,172.16.0.0/12,192.168.0.0./16 But whenever I am using wget (I'm testing the proxy settings using using wget) then wget tries to connect to the proxy for private addresses, but wget localhost works fine and doesn't use the proxy. I also removed all the proxy settings and set the proxy in the shell: export http_proxy="<proxy_url>:<port>" export https_proxy="<proxy_url>:<port>" export no_proxy="localhost,127.0.0.0/8,172.16.0.0/12,192.168.0.0./16" It work when I use the command wget <external_url> or wget localhost but fails when I use the command wget <private address from the $no_proxy variable>. I also tried setting the variables in Ubuntu 14.04 also and facing the same issue. Regards,

• Why my pendrive is showing used space when it is actually empty?

  - by Deb

  I recently got some virus in my pendrive. I removed them using Microsoft security Essential and cleared all data. But it is showing that 47.1MB of space is being used. Is it due to the virus affect? There is no hidden files on the pendrive and I have also set Show hidden files in the Folder and search option. Permission is also granted to everyone. I also use disk management to check any issue but nothing found. I think formatting will solve the the problem but in that case I will not be able to see the data. Is there any command to see the files in cmd or any other way?
