General :: Configuring Machine As A Firewall?

Feb 8, 2010

i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it. i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?

i have heared abut freeradius package but i am not sure will it work in my case?

General :: How To Setup Windows Home Machine So That Can Ssh Into It

Jul 13, 2010

I've been wanting to have the ability to ssh into my Win 7 home machine from my laptop, from anywhere and I'm not sure how to do this. Can someone give me some advice or point me to an article that could show me how to do this? Also, would this affect the security of my home machine (sometimes I do banking there)? The home machine has windows 7 Home X64 bit OS under a Linksys router. The laptop is running Ubuntu Lucid.

General :: Slackware - Ubuntu Machine /home/_ Folder?

Jan 8, 2011

I've got a machine running Slackware64 13.1, and Ubuntu 10.10 32-bit, and today, while installing python-ogre in Ubuntu, I was informed that I had run out of hard drive space on my /home partition.

The /home partition is shared between Slack and Ubuntu, and just earlier today, upon booting into Ubuntu, I got a message that the /home partition couldn't be mounted (before most of the system had loaded. It was still on the purple loading screen) Well simply rebooting fixed this. Then today I suddenly ran out of space, and I thought I was only about half way through the allotted space. Well after some investigation I discovered a folder called /home/_ which was an exact duplicate of /home. Well in need of some extra hard drive space, and in conclusion that it was unneeded, I deleted it. And when I deleted it, everything in /home deleted as well.

First off, what is this /home/_ folder? Where could it have come from? The creation time is about 7 minutes after I created a new user on Slackware, and I think it might have been about 7 minutes after creating that user that I had changed its home directory so that Ubuntu's user config files wouldn't conflict with Slackware's.

Secondly, why did /home's contents delete when I removed /home/_? I already figured out there isn't any way of recovering those files (except for the files I luckily synced with Dropbox)

Third, is there some way to prevent this from happening again? Does anyone have any experience with this? Has anyone heard of this happening before? I already know that /home/_ was not a symbolic link.

OpenSUSE Network :: Accessing A Machine Behind A Firewall?

Oct 22, 2010

I'm in the situation where I'm trying to create 2 private networks using ESX server, all behind a NAT router (static ips are used). I used an openSuse11 vm as a router and was able to configure it so that a machine on one private network was able to access the public network. The problem I have now it that I need to be able to access a machine on the private network from the public network using a different set of IP's.

So if a machine in the private network has an IP of 10.1.0.222 I should be able to ping it using 10.99.0.222 or some other IP. I have never done this before and after reading up on iptables and linux routing I feel more confused than before. Is it possible to add IPs to eth0 (public) and have them mapped to machines on a private network eth1 or eth

Networking :: Setup A Firewall In Home Network Environment

May 2, 2010

I am attempting to set up a firewall in my home network environment. the rest of the environment is windows, sorry I am attempting now so bear with me. what I have is a cable modem coming in, then my fedora 11 box with 2 nics, then the wireless router and the rest of the network.

everything works fine until I put the linux box in. If I put the firwall in the firewall sees the internet but the wireless router directly after does not. I am doing something wrong with the dhcp I am guessing. I dont want the firewall to give the address to the network I want the router to. I tried to get the firewall to do it (yum install dhcp leafnode) but it kept saying something didn't work right.

so I figure I will let the cable modem give the firewall an ip and the router give the rest of the network their ip's but how do I get the firewall and router to see each other and allow passthrough?

Server :: SSH To Work Computer Behind A Firewall From Home Port?

May 5, 2010

I have a computer which has a public IP.My ISP has allowed only port 22 for my machine to be accessed outside from internet.I want rest of my computers which are connected to this machine be accessible via SSH on internet.I can configure IPTABLES to route different ports to internal machines but since ISP has given only one port for the gateway how can I go for it any guesses. I came across some thing reverse SSH tunneling but that has to keep the connection alive all the time at gateway I want my trusted people to be directly able to access the machines on LAN to which they have account to login in this scenario.

Networking :: Access Firewall Public IP From Internal NATed DMZ Machine?

May 13, 2010

I could no handle/circumvent on the past week, despite of the several "googling" and documents reading. I will try to mention all needed bits... I'm managing a network with the following structure:

eth0: internal net
eth1: DMZ
eth2: 10 mbit/sec sync line with eight public /29 IP's + a /30 interconnection network. All public IP's must use the interconnection's network gateway.
eth3: ADSL with ppoe with fixed IP (ppp0).

Now, a few extra info:

- All internal traffic is routed through ppp0 except when it's destined for DMZ and public IP's range.
- DMZ traffic is routed either through ppp0 or eth2. This is done by source IP.
- eth2 has on IP from the interconnection network, and six public IP's are also defined on eth2. Command: "ip addr add ...."

OpenSUSE Network :: 11.3 Home Firewall With IPSec Support For Cisco VPN

Aug 10, 2010

I have a new install of an OpenSuse 11.3 server and I do not see the IPSec Support option when I use Yast to set that I up. I have the firewall setup with 2 interfaces, one external and one internal and that is all working fine. When I connect via my laptop and connect in via a Cisco IPSec VPN, I get connected, but no traffic goes through.

I did search through the forums, but I don't see any hits related to the issue I'm facing. I installed the ipsec-tools, but I am still not seeing the IPSec Support in the firewall section of Yast that I see noted on many Google Searches. Is there a package or something configuration that is needed to get IPSec Support for VPN setup?

Ubuntu Servers :: Users On The Machine Can Login Into Vsftpd With Their Username And Password On The Machine And Go To Their Root Dir "/home/username"?

Nov 3, 2010

I recently installed vsftpd on my server. I noticed that users on the machine can login into vsftpd with their username and password on the machine and go to their root dir "/home/username".Now, I want to give some people a vsftpd username and password so they can upload and download files and folders to their folder, but this folder has to be in the "/var/www/(username)" folder. I don't want them to be able to go to any other folder than their own folder like "/var", "/etc" or "/home" etc. Also I don't want them to be able to login on the machine as a user, through putty for example. They should only be allowed to acces their folder with vsftpd, nothing else.

Fedora Servers :: Way To Ssh Into My Home Machine Through A Browser

I have an ssh server running at home and I'd like to be able to connect to it from an internet cafe that wont let me run putty or java applets. Is there any way to ssh into my home machine through a browser? The only solutions I could find where java based.
In theory, would it be possible to open an ssh connection that reads and writes to a file, and then make a cgi script that writes commands to the file and formats the output to html?

Ubuntu Networking :: Mounting Home Dir On Another Machine?

Jul 21, 2011

I'm running Kubuntu 11.04 .I want to mount my home dir on another machine and log in to the remote machine with the same username and home dir. The problem is that the files on the mounted dir belong to userid 99 (nobody). For example:

on the local machine:

Code:

[erezz@erez-lx:~]$ ls -ln ~/.bashrc
-rw-r--r-- 1 1000 1000 1644 2011-07-20 13:56 /home/erezz/.bashrc

on the remote machine:

Code:

[erezz@remote_machine:~]$ ls -ln ~/.bashrc
-rw-r--r-- 1 99 99 1644 Jul 20 13:56 /home/erezz/.bashrc

Here's what I did (and worked great for me in Kubuntu 10.04):

local machine:
/etc/exports:

Code:

/home/erezz/ *(rw,insecure,sync,all_squash,anonuid=1000,anongid=1000)
(also tried /home/erezz/ *(rw,insecure,sync,root_squash))
local user:

OpenSUSE Network :: Home Machine Desktop Remote?

Sep 8, 2011

I may have to work in another state for some time, and I'd like to access my home machine desktop remotely, like this: Server - home machine, oS 11.4 64-bit, KDE 4.7, 1920 x 1200 screen (currently set to 24-bit color depth), 1 Mbps upload speed, behind a Dlink DL-524 router I manage.

Client: laptop, oS 11.4 64-bit, KDE 4.6.5, 1280 x 800 screen (also 24-bit color depth), unknown up/down speed - probably huge at work, crappy at apart hotel. I'd like to keep the server resolution, if possible, even if the client's is smaller. I want to be able to star/stop KDE apps in the server, move files between folders, and fix the issues that only happen when my wife is at the keyboard (it's a machine conspiracy, she says ). So I'd need to connect to the server's current session/user (which is myself, i.e., same login/password).

What do you recommend for this? I've read Swerdna's tutorial for 11.2/11.2 (a million seen malcomlewis xrdp 0.6 packages for 11.4 (you rock, malcomlewis!), as well as this thread: RDP into OpenSUSE 11.2, however most seem concerned with rdp between windows and linux boxes. Is there something better/faster/simpler for oS-to-oS RDP or should I use xrdp all the same?

Ubuntu Installation :: Upgrade Of Machine With Separate Home Partition?

Jul 16, 2010

I will be helping a friend upgrade from 9.04 through to 10.04 LTS, and I am aware that the machine was installed with a separate home partition. I know a clean install is an option however I am tempted by online version upgrades with the thought that any apps they are using will be carried over. Is this a realistic hope? I know that medibuntu for example does not survive a version upgrade.

Ubuntu Networking :: Home File Server - Connect Or Map Out Folder From Another 11.04 Machine?

Jul 31, 2011

I've set up a PC installed with Ubuntu 11.04 on my home network, given it the name "server" and given it a static IP of 192.168.1.200. I've created a file in the home directory called "Public" and set it to be shared with everyone, basically a chmod 0777 situation. Now, how do I connect, or map out that folder from another ubuntu 11.04 machine? I know how to do it in Windows, just hit "run" and type in "\server" and blamo, I can see everything that's shared on that machine. I can't figure out how to do this with Ubuntu.

Networking :: Unable To Create Samba Account In Home Directory Machine

Jul 15, 2010

I'm not able to create Samba Account. it is showing the error message as below

Failed to initialise SAM_ACCOUNT for user <username>. Does this user exist in the UNIX password database ?
Failed to modify password entry for user <username>

Unix accounts are created in Corporate Office, which is in US. We had a dedicated link from our office to US office. Now this link has been disconnected & now we have a VPN connection through internet to US Office. there is a firewall on both the sides. While creating samba account i tried to give netstat command & i saw it is trying to make a connection to the Unix Server at US, but the connection is not getting established it is showing SYN_SENT.

The port from the Home directory server trying to connect to the Unix server is connecting using Dynamic port but the Unix server port it is showing as PORTMAP. Network guys are not opening all the ports in the firewall. Kindly let me know the DESTINATION PORT that the home directory server is trying to connect to Unix Server, so that i can ask my network guys to open that perticular port. So that i can create Samba account to the users.

OpenSUSE Network :: Firewall Logs Are In /var/log/{firewall,warn,messages} - Clutter?

I suspect this is an initial configuration bug. All firewall logs seem to be going to all

Networking :: Setup Firewall / Sys1 Is Not Connected To Firewall For Testing Purpose?

May 18, 2010

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.

Ubuntu Installation :: Saved Home Directory To Another Machine, And Proceeded To Install From A 9.10 USB Disk \ Error: Out Of Memory?

Mar 16, 2010

I've been running my Dell Mini 9 with the latest alpha for 10.04 since January, but over the weekend I botched things pretty badly and decided to go back to 9.10.I saved my home directory to another machine, and proceeded to install from a 9.10 USB disk. Things didn't go terribly well (I kept seeing "devkit-disks-daemon" crashing) but the install did complete. I shutdown the netbook, yanked the USB drive and powered it back on only to be greeted the grub menu. Choosing any option yields: Code:error: out of memoryPress any key to continue...I did a little searching in places like:HTML there is no mention of that problem there, and running though the command line instructions has the same results. (the linux command seems to be the problem)I've tried re-installed grub from the directions on the page but it is failing with:
