I managed to get the VGA port working ok, but for some reason the DVI port doesn't want to work. I downloaded new drivers for my graphics card, and although it helped fix a few glitches in the system It didn't fix the DVI problem. I am currently running Ubuntu 9.10 and have a Samsung 2443bw monitor with a 1920:1200 aspect ratio.

View 2 Replies View RelatedI am using SSH forwarding for accessing particular ports of a distant computer no problem. I also want to access another computer`s ports as if they are local without individually forwarding ports. In a way this distant computer will become a local computer over the internet. So instead of having localforwarding in my SSH config I just want to be able to say that this IP adress will accept all the port connections, butall those connections will be forwarded to a distant computer over the internet.

I made sure ufw was open to the tcp requests on my new webmin port only. UDP has been disabled. I type in my browser my ip address with the new port, and I get 'problem loading page' now. How can I see the tcp port webmin is set from a terminal on the host computer? Do I goto a webmin folder and change a .conf file?
View 4 Replies View RelatedI'm trying to enable port forwarding so I can use my computer as an FTP server to some friends. Here's my setup:
CLEAR wireless modem <--> LAN port 4 on router (not WAN) and LAN port 1 on router <---> eth0 in Ubuntu 9.10
The modem acts as a DHCP server which successfully assigns an IP address to my desktop system. I can also go onto the internet just fine on my desktop, and any other computer that connects to the router.
I have enabled port forwarding on the modem (not the router because it's being used as a switch, and not using its WAN port) to forward ports 21 and 80 to my desktop. What I don't understand, though, is that when I try to FTP to the modem's WAN IP address, the connection is refused. However, when I use websites such as:
www.canyouseeme.org
www.yougetsignal.com/tools/open-ports/
They say ports 21 and 80 are open (and not other random ports like 22 or 23 which I tried to see if the site simply said everything was open) but I cannot access my site from a web browser.
I was wondering what it was that's stopping computers from the Internet from communicating with my computer? The modem? The router? Configs?
When one should try to connect to port 3306 of particular ip here e.g. 345.56.67.87 it should be redirected to port 3306 of internal machine. This is the scene : How can I access the particular port of the machine which is behind the router . i.e. From out side internet I would like to connect to the port 21 of the machine (192.168.5.8) which is behind router (345.56.67.87) . Here are the details I tried : both side linux (centos)
1.enabled ip forwarding of router (345.56.67.87)
2.enabled ip forwarding of machine (192.168.5.8)
3.implemented some iptable rules: /sbin/iptables -t nat -A OUTPUT --dst 345.56.67.87-p tcp --dport 3306 -j DNAT --to-destination 192.168.5.8:3306
4.iptables -t nat -A OUTPUT --dst 345.56.67.87 -p tcp --dport 3306 -j DNAT--to-destination 192.168.5.8:3306
I tried to google on it mainly it dealt with the iptable rules. of which i applied but error is" can not connect to the port 3306 of 192.168.5.8"
I have a need to displace a serial port from one Linux computer to another computer running Windows (XP.) I am running Heyu on a Linux machine in a closet. The power leg for that circuit cannot let the X10 communication reach most of the rest of the house. Where it does work, is from my office but there I am running XP computers only.
I would like to plug the CM11A into my XP computer, share it's serial port and have the home automation computer (running Heyu and Linux) use the LAN to get to the XP serial port without Heyu knowing it is not a local port. Has anyone done this? Can I share a serial port in XP? Can I get Linux to map a serial port to a virtual one on another machine?
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.
View 3 Replies View Relatedwhile my brother was browsing the web on my windows partition he had a blue screen pop up, one of the soft/hardware error ones, not a true BSOD, anyways, ever since my lan port on the computer seems to not be activiating as no wired connection is recognized. The lan port/card is directly attached to the Mother Board, it's a gigabyte motherboard in a self-build computer. I'm just wondering if there's anything I can do to troubleshoot this and see if it is truly a hardware problem or if its something else.
View 9 Replies View RelatedI notice that my bittorrent client is capable of automatically setting up port forwards with my router, and I want to know if I can do the same in a shell script. The reason is, that since my router is stupid and won't let me keep static IP addresses (it seems they forced a DHCP refresh every week to make me want to pay for a more expensive model which doesn't), I need to get my computer to change the port forward to follow my computer's changing internal network IP address. I have a couple of port forward manually entered into my router settings for web interfaces to bittorrent etc, but of course these have a good chance of being invalidated at each DHCP refresh cycle.

I would like to run ssh server on a port other than 22. SSH works fine both inside and outside (using port forwarding). HOWEVER, if I go to ssh_confing and change the port to port xxxx following the guidelines here: [URL] (adding 'Port xxx") to the ssh_config file.
I get the following message when I type "ssh localhost":
ssh: connect to host localhost port xxxx: Connection refused
I also issued a "ufw allow xxxx", and it did update the table... but I still cannot connect on the specified port. I am running this on Ubunto Server 8.10, and there is no firewall set up. I have tried various ports, and I did restart the server after each change to ssh_config. If I must, I will run on port 22, but I prefer a wee bit more security. do not respond with router issue, this is not connecting through the router at all. I am just trying to connect from the local machine (localhost).
In Summary:
ssh localhost (works on port 22)
ssh localhost (does not work on any other port other than 22... connection refused).
I have a virtual server setup on port 80 that works fine, however, if I change the port to, say, 8080 the browser then fails to connect.I'm using webmin to configure everything, all the other settings seem to work as I would expect.I get the error "Safari canī open the page http://192.168.0.12:8080 because Safari cant connect to the server 192.168.0.1." in safari, and i get something similar on the xubuntu machine in firefox connecting via localhost.It's almost as though theres a firewall in the way, but I think it's more likely to be some config problem.

I have tried setting apache up on port 8000, because my ISP blocks port 80.
When I try to listen on just port 8000, I can never connect, internally or externally. When I try to listen on both 8000 and 80, my internal computers will drop the 8000 from the url and connect on 80, and external computers try to do the same thing, but can't get through on port 80.
I know my router is set up correctly, I have 80, 8000, and 8888 all being forwarded, I have confirmed with [URL] that 80 is blocked, but 8000 and 8888 are open. I am able to connect to gnump3d through port 8888 internally and externally, but not apache2 on port 8000.
netstat -tnap confirms that apache is running and listening on ports 80 and 8000 to all users.

View 8 Replies View RelatedI've used iptables since it replace ipchains, and I've never had a problem like this.The problem is, as you can see by the title, that port forwarding simply does not work.
network topology:
Slackware Linux Server:
eth0 - LAN (192.168.0.0/25)
eth1 - DSL Static IP
eth2 - cable Static IP
eth1 is our standard office connection; it handles all of our default traffic (web browsing for the staff, email, etc). eth2 is our VPN connection, as well as use for all incoming connections (www, etc). Behind the linux box I have a series of Windows Server 2008 R2 boxes that are used to run our office software, website, etc - I don't care how nice they make their products these days, I simply don't trust any MS box open to the net.
Therefore, this leaves me with having to port forward port 80 from eth2 to the internal IP address of the web server.
My ruleset is as follows:
$WWW - ip address of the web server
iptables -A FORWARD -d $WWW -p tcp --dport 80 -j ACCEPT
iptables -t nat -A PREROUTING -i eth2 -p tcp --dport 80 -j DNAT --to $WWW
Running ip route shows that I have routing entries for all 3 networks, and I can ping, ssh, etc to any of the addresses without issue. OpenVPN connects across eth2 as well, and all 15 of my VPN tunnels work fine. However - and here's the kicker - if I delete the default route and replace it with the route for eth2, port forwarding works fine.
If we accept that my networks are as follows:
192.168.0.0/25 - eth0 net, gw .1
1.1.1.0/29 - eth1 net, gw .1, eth1 ip .2
2.2.2.0/30 - eth2 net, gw .1, eth2 ip .2
then ip route reveals the following:
2.2.2.0 via 2.2.2.1 dev eth2
2.2.2.0 dev eth2 scope link src 2.2.2.2
1.1.1.0 dev eth1 scope link src 1.1.1.2
[code]....
I have the following setup and Im trying to forward all incoming connection on port 1194 on eth2 which is the external network to ip 192.168.10.100, but seems its not working.
Current config:
# Generated by iptables-save v1.3.8 on Sun Nov 16 00:00:54 2008

:PREROUTING ACCEPT [26751696:2175544875]
:POSTROUTING ACCEPT [339911:19096812]

plus im adding the prerouting:
iptables -t nat -A PREROUTING -i eth2 -p tcp --dport 1194 -j DNAT --to-destination 192.168.10.100
This configuration doesnt work. I also I have tried:
iptables -D PREROUTING -t nat -p tcp -d XX.XX.XX.XX --dport 1194 -m state --state NEW,ESTABLISHED,RELATED -j DNAT --to 192.168.10.100:1194
and the same its not working. Connecting thru telnet to the domain: telnet mydomain.org 1194 doesnt work, but within the server, running telnet 192.168.10.100 1194 it works.
