View 2 RepliesI'm running 10.04 without having installed a firewall is that ok? because, i'm also bugged by audio/video and mouse problems which build up and i must warm boot to remedy. (although the drum fanfare at start-up doesn't sound quite right ether?). furthermore i would like to open the port for my torrent client Transmission, but the elements of the web pge (192.168.1.1) are flickering.

View 1 Replies View RelatedLet's say I have a Linux workstation at work, behind a firewall. So even though I may have a remote access server set up on it (such as the most excellent NoMachine NX Server), I can't access it from home.
My home network happens to have a Linux server. Is it possible to ssh from work to the home Linux machine and set up a tunnel so that once I'm at home, I can run the NX client, point it to my home Linux box on some port like 9000, and have that forward through the tunnel to port 22 on my work Linux box? How would I set this up?
I never installed one, but if I wanted to find out for sure if I have one how would I do that?
View 2 Replies View RelatedI'm doing some light web development, I installed php5 and apache on my laptop and read that when running apache your computer is technically a server and is thus vulnerable to computer wankery. I'm looking for advice on whether or not I should install a firewall or if I don't really need it. The work I'm doing is not a professional website, just a place for some experiments. All the info I found on the web was targeted to professional web-developers, not so much for amateurs like myself. What do you think?

Firewall includes 2 NIC:
NIC1 <IP PUBLIC>
NIC2 192.168.10.1
I installed 1 web server IP: 192.168.10.2
I have some PC IP range: 192.168.10.10->20
I set rules NAT on firewall and PC & web server can connect internet good, but I have problems:
When PC access to web server with IP 192.168.10.2 that ok, but PC can't access to web server when using IP Public. But outside internet, I can access to web server using IP Public.

Is there a firewall installed and running in 10.04? If so are there any gui tools for configuring it and where are they? If there is not a firewall, what should I install to get one properly up and running?

Just installed Linux (Ubuntu 10.10-net book-i386) on an acer 5310 laptop, everything is working great except for the internet. Google home page takes over a minute to load on Firefox, the actual search results takes only a second but then it takes 2 or 3 minutes to load any site i click on. I have broadband, only 1mb, but it worked perfect on the previous OS, also using Firefox.

I had a samsung 1TB HDD that I used for storing data, on an xp machine, so it was formated as NTFS.I moved this HDD to another machine and installed Freenas on it, and the installation worked fine (fyi, I used the tutorial posted here :[URL]..During the installtion, Freenas installed it's system files to a new small UFS partion. After finishing the setup, I realised that I had changed the file system of the other partion (980gb, previously NFTS) to UFS and now I don'T know how to go back. I had about 400gb of data on it and I'm pretty sure it's still there, but don't know how to get it back.
I tried messing around with recovery software such as R-Studio, and I was able to see some of my files so I know they're still there. After quite a bit of googling around, the only solution I seem to find is using gparted which is a tool to modify partions file system without loosing data, but I'm afraid to use it.
So is there a way to browse NTFS data on a UFS partition and convert it so FreeNas can see my files ? Or is there a way to put the partition back to NTFS so I can back up my data to another drive before I lose something valuable ?

View 2 Replies View Relatedwe have a server running with Suse linux many years. Meanwhile we changed server hardware about 4 times, mostly also updating to newest Suse version. We used to copy group, passwd and shadow to a backup medium, installed the new system and restored those files onto the new system and all was running fine. Now, some weeks ago we installed 11. on new hardware and after restoring those 3 files after rebooting the system hangs when starting GUI. I can boot into runlevel 3 and login with no problem, but when I boot into runlevel 5 mouse and keyboard are frozen. Also when starting GUI from runlevel 3 with startx mouse and keyboard immediately freeze. If I restore the files group, passwd and shadow as they came from fresh new installation I can reboot and login in runlevel 5 without problems.
OK, if I compare the userlist, as it is generated bei installation,there are some usernames I formerly not had in older Suse versions. I don�t know if this can make problems? I tried to edit the files, to combine the system users from 11.2 with the list of local user names from the old system but without success, again the mouse and keyboard freeze.So some questions arise:1) Why now mouse and keyboard freeze in xsystem, when there are changes in the user list (but only in runlevel 5)2) What is the correct way to save and restore users and groups from old to new system. I googled several hours but did not find a smart way. Maybee someon can point me to a link or a howto where I find the solution
I switched over to Fedora a couple of days ago. I'm using the built-in firewall shipped with it but I can't find out how to enable logging of dropped packets. Among others I'd like to use psad that needs firewall logging. Is there an easy way to do this? I'm not an iptables "expert".
View 6 Replies View RelatedI suspect this is an initial configuration bug. All firewall logs seem to be going to all
three files. That causes a lot of clutter in the log files, and makes it difficult to see whether there are any serious problems being logged.
I am learning to setup firewall in my home for that i have selected four system(sys1,sys2....sys4) for testing .I have configured sys2 to act as a firewall with two NIC. sys3 and sys4 are inside the firewall . sys1 is not connected to firewall for testing purpose.
the IP assignments are follows :
sys1 : ( fedora, not connected to firewall i am thinking, But i am not sure )
IP : 192.168.2.1 ,
gateway : blank
dns1 : blank
dns2 : blank
sys2 firewall ,IPTABLES )
code....
what happened is that sys1(not connected to firewall) can ssh to sys4(connected,inside firewall),since the rules are written not to ssh form sys1 to sys4..
then I came to know whatever the request I give, It directly goes as sys1 --> sys4. Not as sys1-----> sys2(firewall)---> sys4 .and the firewall is not filtering and processing anything for both inbound and outbound (i think it's my mistake some where). the requests are directly going inside without firewall.
I'm trying to build firewall on Debian with 'Firewall Builder'. But it won't let me compile and run unless one interface is set as management. There are two interfaces on my computer: 'eth0' and 'lo'
I don't want to be able to configure firewall remotely, so could I use 'lo' as 'management interface'?

View 4 Replies View RelatedI will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
