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'?
Can we use iptables as firewall instead of Juniper firewall

View 1 Replies View RelatedA client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.
This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.
Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.

View 2 Replies View RelatedI have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

View 11 Replies View Relatedwe're trying to build a simple Firewall/Gateway out of Ubuntu. We have a machine with 2 NICs running the latest version: 10.04.We have been able to set up the gateway/routing fine using both the built in Internet Connection Sharing as well as using Guidedog. The current setup we are testing is using Guidedog.For the NICs we have set eth0 as our internet connection and eth1 connects to the LAN. We've manually set all IPs...no DHCP at this time.
Next we try to install a firewall. We have tried both Firestarter and Guarddog. After setup with either, the Ubuntu box is still able to get online and access web sites but the LAN gets cut off. No access at all. We are currently running Guarddog and have set the proper protocols (DNS, HTTP, HTTPS) and have also followed the tutorial found here.
However, no matter what settings we make as soon as we re-enable the firewall the LAN is cut off. Disable the FW...LAN is back online. We even set up an "Allow All" protocol allowing all ports from 1:65535 and still we get cut off as soon as the FW is enabled.
We saw this same thing happen with Firestarter and my understanding is they're using the same basic Linux FW underneath? SO, what is it we're neglecting to do? Why does the FW completely seal off our LAN connection no matter what we've told it to allow?
Ultimately, here's the layout we're after:
Internet (T1) <> Firewalled Ubuntu <> LAN
when do we use havp in firewall?

View 3 Replies View RelatedEnvironment:RHEL 5.2 and 5.4 AP x86_64, 2 drives (sda, sdb), installing without optional features like clustering and virtualization. I have tried this for a couple of days now and just can't get it to work. My goal is to take the RHEL 5.2 DVD and RHEL 5.4 DVD and install them on separate drives of the same machine. I want the grub menu to give me a choice. I prefer to understand the steps and choices offered me by the install dialog to do this rather than fiddle with grub.conf. If that is not possible, I will write up the bug.
So far, I just get the the error 13 when trying to start the grub added second OS. I have read elsewhere that "Anaconda frequently recognizes the other operating system and sets up grub so you can boot from either operating system". That would be nice. The install dialog lets me choose a drive to install to. I have figured out that I need to check "review and modify partitioning layout" to enter the advanced grub choices. Do I have it install a boot loader for the 1st OS? Trying to add the 1st OS during the second OS install creates a grub conf with no kernel line in the added boot stanza.
I am on Linux on machine LOCAL (my notebook).I ssh into a company machine REMOTE which is behind a firewall and ONLY allows incoming ssh connections (port 22), no outbound connections whatsoever. I do have full root access on both, LOCAL and REMOTE, REMOTE is however a VPS and behind a hardware firewall.I now need network access on REMOTE (HTTP and other protocols) for downloading and building some software. I also need to access to NON HTTP protocols such as git.
I was hoping to set up a reverse SSH tunnel for using my LOCAL machine, where I could be running a socks server. So that network access on REMOTE would be redirected over the SSH tunnel to a socks server running on machine LOCAL.How would I go about setting something like this up?
I am looking for some firewall for ubuntu with GUI, something like comodo firewall available for windows, which lets you to allow only specific processes to connect to Internet. Currently I am using Fire-starter but I dont like it much also it is very old and doesn't allow you to block specific program.
EDIT: I need it for personal use not for any server.
How do I know which firewall is installed on my Red Hat 4 system?Are there any commands or procedures I can follow?
View 2 Replies View RelatedAfter metering the power being used daily in my computer room, I decided that I needed to get somewhat greener. So I am updating all my equipment and getting rid of the old towers and power hungry equipment. So far so good, except for the box running Smoothwall.
It is an old IBM 300GL from the '90s that is apparently never going to die. But it is noisy and not exactly low powered and has to be on all the time. The only machines that I have presently that can be used as a replacement are full blown AMD 3000 and 6000's, and I hate to waste one of those just to be a firewall. I can find some mini cube systems that are very low powered - some even run on just a wall cube - but can't find one with two ethernet ports, and of course there is no plugin buss on a tiny box.
I'm using Plesk as my control panel. After the PIX was installed, I mapped the old IPs to the new IPs. Port 80 is OPEN. My PHP includes won't work when I use the domain, actually nothing works when I use the domain infront of it. I tried adding 10.0.0.1 [URL] to /etc/hosts and still had no luck
