Networking :: Firewall As Router - Pros Versus Cons
Jan 27, 2010I'm mentoring my local high school's IT club as they prepare to participate in a cyberdefense competition (see IT Olympics). Generally we are given four boxes and need to set up a network that provides certain services (which services change from year to year, but usually include a web server, email server, FTP server, and an application server of some sort) and support client PCs that connect from the WAN. The red team then tries to break into our network to steal "flags" from our servers and to set their own "flags" on our servers.
Generally we set up the firewall with two network interface cards (one to the WAN and one to our LAN), and connect the LAN NIC to a router, which then connects to the other three boxes. But we do have the option of installing additional NICs in the firewall and configuring it as a router. I can't shake the feeling that there is a security advantage to such a configuration, but I can't say what that advantage is. Perhaps something with configuring ipTables on the internal boxes to accept connections only from the firewall's NIC, and then only for the services we want that box to support (to prevent an intruder from connecting directly from one box to another)?
Ubuntu :: Formatting Drive - Different Pros And Cons Of Various
Apr 24, 2011I am trying to format an external hard drive and wanted to know the pros and cons of various different formats offered in Linux. I hear that ext4 is better (most stable) than anything else (better than ext3 or ext2) for Ubuntu. I wanted to know where I can obtain more info on these various formats. I want a format that would be (1) as stable as it can get in formating a hard drive, and (2) readable and writable in both Windows and other versions of Linux (say Mandriva).
View 9 Replies View RelatedSlackware :: Pros And Cons To Having Both /usr And /usr/local Partitions?
Jun 1, 2010Having both a /usr and /usr/local partition seems logical: A seperate partition for /usr would preserve the /root partition since it changes in size, while reducing the initial install size of /root. Having a /usr/local partition would then preserve custom software (ie. scribus, bender etc.)not distro related, scripts, and settings.
Would having /usr and /usr/local create any problems locating files? I understand that /usr/local has a relative function depending on whether it is being used as a machine in a network context or whether it is being used as a desktop and /usr/local refers to user custom files. I am setting up slackware64 multilib and think I want to preserve both distro and user files to expedite do overs keep trouble shooting clean.
General :: Unity And GNOME Shell Pros/Cons?
Jan 20, 2011I'm thinking about the near future with Unity and GNOME Shell. I've tried both a little and wondered what I'm missing; they seem pretty much the same on the outside! I'm assuming it's similar to GNOME and XFCE; they look quite similar, with XFCE aiming to be lighter-weight, but what's the difference between these two new 3D environments? Why did Ubuntu fork the GNOME environment when it barely differs from what GNOME are providing?

Apr 28, 2010I understand it is not generally a good idea to mix 13 and 13-current packages but I am installing OpenProj which requires JDK and the installed JRE (6-18) is up-level from 13's JRE (6-16) and back-level from the 13-current JDK (6-19). Presumably JRE and JDK should be at the same level. Would it be better to take both JRE and JDK to 13-current (6-19) or to take both to 13 (6-16)?
View 3 Replies View RelatedSlackware :: Pros/Cons Installing From Source Versus Packages
Mar 15, 2011At work / home / laptops I have about 5 slackware machines. I have always tended to install new packages on each machine from source, generally using slackbuilds when available. I thought I would try 'libreoffice' and reading alien-bobs blog I deduced that a full from source install might be pretty difficult, so I followed his advice and just took the package (.txz file) and used installpkg. To my slight surprise this installed and ran perfectly.
Now I'm wondering if someone would clarify under what circumstances you can just take the slackware package from one machine to another and install. More generally I guess what are the main advantages of building from source. Is it mainly about availability of all the required dependencies?
General :: Pros And Cons Of Virtual Hosting Versus Separate Machine
Feb 9, 2011I am having vitural hosting around three websites using Centos. I need to type in the full domain name include www to enter the 2 of the vitural hosting sites. Pros and Cons of vitural hosting vs separate machine? I got a questions about static IP. Assume I having a linksys router with port forwarding function, I have three seperate machines with different private address connect to the same linksys router. Can I entry all private address forward to port 80? Does it work? If I insist to host website on three machines, does that mean I need 3 static IP and 3 linksys router? I got two conventional web services only showing information but one got mysql db for user to input data, thats why I asking if it is good idea to seperate web page on different machines.

Jul 29, 2010I am trying to decide whether or not to use LUKS with LVM install for NAS Box, mysql, postfix, ddns, bind, NFS, sshd, Appletalk, maybe samba. I have decided to give LVMs a try but not sure how LUKS will affect access to services. LAN includes Standalone headless web server(not on LVM, no LUKS). Aren't permissions,iptables and firewalls sufficient? Not sure how services are supose to interract if everything is encrypted especially root?
So far what I have read recommends vgOS /, swap, /var, /tmp encription and vgdata /home encryption but no one tells how they did it. The 2 servers I'm working on only have small /home for admin stuff and considering making NAS headless, except i read somewhere that some gui would make it easier to manage mysql which brings me to the question if I don't install X on NAS can I ssh in with my desktop using its gui? I am experimenting with minimal server tagfiles. LUKS and LVMs are new to me. Decided to use LVMs to seperate OS from data, different data types and resizing flexibility. I have read some material on LUKS just wonder if its more complicated than my needs require. Certainly i don't want to leave myself open to someone just distroying my setup for kicks.
Networking :: Networking Is Not Getting Out Of The Dosbox Instance \ Needs To Have Some Config In Place To Link Networking Over To Dosbox?
Jan 31, 2011I am attempting to setup and old BBSinside of DosBOXI've built one of the DosBOX Megabuilds, with the NE2000 patch.It uses libpcap in order to piggy back on top of the system's NIC. All of the dosbox side appears to be working.My system comes up, gets the MAC address i told it to use, i can load a packet driver in dosbox, all of that seems well and good. The issue, i think, is on the linux side. It's built on a Fedora 14 box. I'm getting the feeling that networking isnt getting out of the dosbox instance. Does it seem possible that fedora needs to have some config in place to link networking over to dosbox?

Jan 16, 2011I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.

Networking :: Networking Routing \ Use The Terminal To Assign Server Eth0 A Proper IP Address?
Jun 8, 2010i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
Fedora Networking :: Networking - Connect To The Internet Using BSNL Broadband Connection
Mar 6, 2010I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

Ubuntu Networking :: Cable Modem Networking - Can't Connect To Each Other On The Home Network
Feb 14, 2010I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

Ubuntu Networking :: Wired Networking Not Working At Work - Fine At Home ?
Aug 24, 2010I just started having a problem with my 10.04 laptop a few days ago, maybe Thursday, last week. When the computer is plugged into my home network (standard 192.168.1.1 sort of IPs) it works fine, but when I try to connect to my work network (130.15.90.XX) I am unable to pick up an IP. The router in my office is working fine, all the windows boxes can connect.
I've also noticed that when the computer is plugged in at work the notification icon for the networking indicates it is looking for a wireless connection (rather than the normal up/down arrows), even if wireless is deactivated
I can set a static IP in /etc/network/interfaces and everything works, so it seems to be a DHCP problem?

Ubuntu Networking :: Dual Ethernet Networking - Lose Internet Connectivity?
Apr 18, 2011I have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.
