  • scp stalls and ssh sessions freeze up (but eventually start again)

    - by coleifer
    I am running ubuntu on various computers on a home network. Some are on 9.04x64, some 10.04x64 and one 9.04x32. Running scp with a large file starts out at 2.1 mbps and drops down to about 200k, stalling and dropping until the transfer is complete. I've noticed this when I have a secure shell open on any of these servers as well. I have tried this with 2 different routers, both brand new, different brands.

  • Running Radius on a Novell Backbone

    - by YsoL8
    Hello I am a rookie network engineer and I've been asked to create a secure wireless system intergrated with an existing network. So far I'd decided to use 802.1x secuity with a Radius enabled server over a Novell backbone. My question is: does Novell still support this type of server setup? I heard rumours it is at the end of it's supported life and I'd like some confirmation. Also can I get some recommendations on better backbone / server providers. Cheers

  • Can the OS X unlock panel trigger a login hook similar to loginwindow?

    - by Allen
    I'd like to automatically run a shell script every time I authenticate onto my computer. However, all the info I can find about loginhook and Global LoginItems applies only when authenticating to "loginwindow," and not to the "unlock panel." The unlock panel prompts for a password when waking up from sleep or from a locked screen. Is there any way to trigger script execution after successfully unlocking the screen?

  • VPN/IPsec for RD, port 80,

    - by Andrew
    I have two Windows VPS's that talk to each other. 1) I already firewall Remote Desktop to a few IPs. I want to require me to connect instead to the server via VPN (IPSec?) in order to then be able to RD. 2) I want to also only permit access to port 80 on the server if I am VPN'd in to the server (authenticated) 3) If possible, I want to secure communication between other VPS's I have using the same method? Thanks

  • Password protect a folder

    - by Lee Treveil
    What are the available options for password protecting a folder? I'm talking about requiring a password to actually access the folder, not just user access rights. Is the third-party software out there secure and stable? What are the recommendations?

  • How to combine AWS and dedicated external servers?

    - by rfw21
    I have an extensive network of servers all currently hosted on AWS EC2. For reasons of cost I plan to gradually migrate to dedicated servers where possible. So: How can I best combine AWS and non-AWS servers in my network? Ideally, I should be able to assign internal IP addresses to the external servers, include them in AWS security groups and ensure that all private traffic between my AWS servers and external servers is secure.

  • Modem with support for wired 802.1x

    - by menko
    I'm looking at allowing internet access for only a few scattered users on a school network. One method I'm considering is using 802.1x authentication for the modem. Of course there are simpler options like only allowing specific IP or mac addresses, but policy requires something more secure than this. So, are there any modems with 802.1x wired authentication? All my searching on this yields info about wireless.

  • Installing a wiki on Snow Leopard

    - by JPCF
    Hi... I want to install twiki on my mac and serve it from ~/Sites/. Because the wiki has code to be run, I have to modify the user and group of wiki's files and directories, but I'm not sure about the following: 1) It is secure to change the user and group of the directory to the web server's group? If not, what can I do having into account that I'll not put 777 permissions on those files? 2) How are named apache and web user groups? Thanks

  • CPanel has two entries for site, need to use SSL one

    - by beingalex
    I have a website that is meant to be using SSL, however there are two entries in Cpanel's httpd.conf which seem to be causing an issue. When I visit just www.website.com I require it to go to https://www.website.com. However I have to write the https:// directly for the site to work. The secure site also has a different IP. I am not meant to edit the httpd.conf directly either and am unsure as to how to change the following directives: <VirtualHost 1.1.1.1:80> ServerName website.com ServerAlias www.website.com DocumentRoot /home/websitec/public_html ServerAdmin [email protected] ## User websitec # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup websitec websitec </IfModule> <IfModule !mod_disable_suexec.c> <IfModule !mod_ruid2.c> SuexecUserGroup websitec websitec </IfModule> </IfModule> <IfModule mod_ruid2.c> RUidGid websitec websitec </IfModule> CustomLog /usr/local/apache/domlogs/website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ."

And this is probably the issue, however if I try to change the IP for the site in WHM I get an error saying that the IP (2.2.2.2) is already in use. Which it is I guess. Any help is appreciated.

  • Load balancers, multiple data centers and url based routing

    - by kunkunur
    There is one data center - dc1. There is a business need to setup another data center - dc2 in another geography and there might be more in the future say dc3. Within the data center dc1: There are two web servers say WS1 and WS2. These two webservers do not share anything currently. There isnt any necessity foreseen to have more webservers within each dc. dc1 also has a local load balancer which has been setup with session stickiness. So if a user say u1 lands on dc1 and if the load balancer decides to route his first request to WS1 then from there on all u1's requests will get routed to WS1. Local load balancer and webservers are invisible to the user. Local load balancer listens to the traffic on a virtual ip which is assigned to the virtual cluster of webservers ws1 and ws2. Virtual ip is the ip to which the host name is resolved to in the DNS. There are no client specific subdomains as of now instead there is a client specific url(context). ex: www.example.com/client1 and www.example.com/client2. Given above when dc2 is onboarded I want to route the traffic between dc1 and dc2 based on the client. The options that I have found so far are. Have client specific subdomains e.g. client1.example.com and client2.example.com and assign each of them with the virtual ip of the data center to which I want to route them. or Assign www.example.com and www1.example.com to first dc i.e. dc1 and assign www2.example.com to dc2. All requests will first get routed to dc1 where WS1 and WS2 will redirect the user to www1.example.com or www2.example.com based on whether the url ends with /client1 or /client2. I need help in the following If I setup a global load balancer between dc1 and dc2 do I have any alternative solutions. That is, can a global load balancer route the traffic based on the url ? Are there drawbacks to subdomain based solutions compared to www1 solution? With www1 solution I am worried that it creates a dependency on dc1 atleast for the first request and the user will see that he is getting redirected to a different url.

  • OS X: How to force traffic through a specific SOCKS proxy on a per-app basis?

    - by GJ.
    I'm running a certain desktop app (actually via AIR if it makes any difference) which doesn't have any built-in proxy configuration settings. I need to get all traffic just from this app directed through a secure SOCKS proxy. This implies I can't use the global network preferences, as these would affect many other apps. Is there any way to force all network communication through a given SOCKS proxy on a per-app basis?

  • Chroot for Mysql running on Ubuntu 10.10?

    - by Calvin Froedge
    Prompted from a question about MySQL server security best practices, I've been running through this list (with a few minor alterations) to properly secure my server database server: http://www.greensql.net/publications/mysql-security-best-practices On step 10, I'm told to change the root directory for the mysql user using chroot, but very few specifics are provided and I'm not sure where to start. Does anyone know of a good resource for walking me through the steps to properly create a chrooted environment for Ubuntu 10.10?

Or does it only work on a per-subdomain basis? thanks a lot for helping me out

  • How can I download a cryptographically signed version the Java JDK from Oracle?

    - by user53352
    When going to Oracle's download site (https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=java_ee_sdk-6u1u21-wjdk-oth-JPR@CDS-CDS_SMI) to download JDK for EE the download is over HTTP (not HTTPS) and the executable isn't signed. As far as I can tell, there are also no SHA1 hashes published so I have no way to verify that the code hasn't been altered. Does anybody know of a way to verify this or has Oracle not given any way to make sure this is secure?

  • Securing debain with fail2ban or iptables

    - by Jimmy
    I'm looking to secure my server. Initially my first thought was to use iptables but then I also learnt about Fail2ban. I understand that Fail2ban is based on iptables, but it has the advantages of being able to ban IP's after a number of attempts. Let's say I want to block FTP completely: Should I write a separate IPtable rule to block FTP, and use Fail2ban just for SSH Or instead simply put all rules, even the FTP blocking rule within the Fail2Ban config Any help on this would be appreciated.

  • Restarting or stopping apache results in waiting forever

    - by steko
    I have two simple WSGI apps running on top of mod_wsgi and apache2 on a test development server. There is no mod_python on this machine. The WSGI configuration is as follows WSGIDaemonProcess tops stack-size=524288 maximum-requests=5 WSGIScriptAlias /tops /home/ubuntu/tops-cloud/tops.wsgi <Directory /home/ubuntu/tops-cloud> WSGIProcessGroup tops WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> WSGIDaemonProcess flaskal maximum-requests=5 WSGIScriptAlias /c14 /home/ubuntu/c14/flaskal/flaskal.wsgi <Directory /home/ubuntu/c14/flaskal> WSGIProcessGroup flaskal WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> If I make changes to the app, I need to restart the web server, so I would expect that a simple sudo service apache2 restart does what I need. Same goes for any changes to the config (e.g. number of maximum requests, etc). Instead, it never ends "waiting", like this: $ sudo service apache2 restart * Restarting web server apache2 ... waiting .................................................. until I just do CTRL-C. At that point, the only way to resume a working server is to kill the process and restart it, not very convenient. The same happens with the stop command. The error logs at the "debug" level show the following lines after a failed restart [Wed Nov 14 21:55:19 2012] [notice] caught SIGTERM, shutting down [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Shutdown requested 'tops'. [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Stopping process 'tops'. [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Destroying interpreters.

[Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Python has shutdown. If I then try to restart again (with the process still running), I get the following error: * Restarting web server apache2 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. Unfortunately the Apache error log doesn't have anything. When apache2 is running properly, both apps work without any problem.
