• Making Puppet manifests/modules available to a wide audience

  - by Kyle Smith

  Our team rolled puppet out to our systems over the last six months. We're managing all sorts of resources, and some of them have sensitive data (database passwords for automated backups, license keys for proprietary software, etc.). Other teams want to get involved in the development of (or at least be able to see) our modules and manifests. What have other people done to continue to have secure data moving through Puppet, while sharing the modules and manifests with a larger audience?

• Is it safe to run Postfix w/o securing it?

  - by Miko

  Does postfix need to be secured before it's safe to run it on a production server? I rely on Monit to notify me if certain processes are down or in trouble. For this purpose and this purpose only, I need postfix on the server so that Monit can send me email notifications. If it's necessary to secure Postfix before deploying it, what are some steps I can take to make it safer?

• 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.

• Windows 64bit Sandboxing software alternatives

  - by Pacifika

  As you might know sandboxing software doesn't work in 64bit Windows due to patchguard. What are the alternatives for a person looking to test untrusted / temporary software? Edit: @Nick I'd prefer an alternative to VMs as I'm not happy with the extended startup time, the extra login sequences and the memory overhead that accompanies booting a VM solution to test something out ocassionally as a home user. Also it's another system that needs to be kept secure and up to date.

• nginx rule to capture header and append value as query string

  - by John Schulze

  I have an interesting problem I need to solve in nginx: one of the sites I'm building receives inbound traffic on port 80 (and only port 80) which may have a certain header set in the request. If this header is present I need to capture the value of it and append that as a querystring parameter before doing a temporary redirect (rewrite) to a different (secure) server, while passing the paramater and any other querystring params along. This should be very doable, but how!? Many thanks, JS

• ConfigServer Security and Firewall -- after setup, how much daily management required?

  - by Hope4You

  I'm looking at using ConfigServer Security and Firewall (CSF; iptables-based). After I configure it properly, how much daily ongoing management is required of me to keep my server secure? Am I going to be flooded with "alert" emails that I need to check? Or does the firewall automatically take care of most security threats for me? Note: I understand that there's more to server security than just a software firewall, but this question is specifically for CSF security management.

• 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

• Remote Desktop over VPN or SSH?

  - by Jonathan

  I want to provide a remote employee remote desktop into a PC in the office and am trying to decide between the following two options: Use Microsoft VPN to get him a local network IP.

• Which VPN-Software for Road-Worriors

  - by Phoibe

  Hello, I am using Unix (Debian) as my server platform and want to configure the following: A remote user can connect to a secure VPN server and use its IP to access the Internet, mostly for browsing and e-mail. I read a lot about OpenS/WAN+L2PT and OpenVPN but I am still confused how I should configure it. I would prefer IPSec+PPTP/L2PT since the road warrior doesn't have to install any extra software on iPhone/Windows7. Is there a good how-to for IPSec or what would you suggest?

• Autoscaling EC2 with NFS mounts

  - by Jamie Taylor

  I'm trying to set up a shared filesystem on EC2 and I've read tutorials such as this: http://blog.ronaldmccollam.com/2012/07/configuring-nfs-on-ubuntu-in-amazon-ec2.html In step 2 it talks about configuring the exports, for this I need an IP range but when I'm auto-scaling I can't predict what the IP will be before it scales. Is there any other way of doing this while still staying secure? Thanks Edit: Just tried s3fs, didn't seem to work properly

• 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

  - by Sameer

  We would like to synchronize our users or backup their laptops to the data center – looking for suggestions/alternatives to synch them to the data center where they don’t have to know about it.

  I'va remote linux debian server that 99.9% of the time I access via ssh remotely. However I was aware that the local terminal is sitting there with a logon prompt.

• 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
