Ubuntu Networking :: Remote Web Server Access?

Sep 7, 2010

I have installed Ubuntu Server (lamp+openssh) on a laptop in order to use it as a testing web server for my projects. After configuring it I've also installed the GUI to make things easier as I'm not very proficient using just the command line.

I'm using the wireless connection on the laptop to communicate with the router and my main desktop (Windows). I've assigned it a static local IP (192.168.1.99) in order to be able to access the sites on my web server from my desktop, and everything works fine.

Now comes my problem: I need to be able to access those local sites from a remote location (outside of my local network) as well. How can I do that?

Ubuntu Networking :: Remote Access To Server?

Mar 29, 2011

We have installed Ubuntu Server 10.04 LTS for file share (Samba) at our local network.

I want to access my local server (Local IP 192.168.1.200) via internet from remote location. I have already installed SSH on our ubuntu server. I understands that using "Putty" we can access our server. Furhter, our Internet IP is dynamic (which is not an issue for us).

Networking :: Accessing A Remote Server Using Ssh Or Sftp

Apr 30, 2010

I cannot access a remote server(Ubuntu) using ssh or even using sftp from my ftp client. I've been accessing this server regularly for many months with no problem until now. There is a web server running and that's OK, so no problems there. I asked the owner of the server if he could access using ssh from within his LAN, which he could! So openssl is working from within the LAN, but not ouside of the LAN. I access the remote server by using one of [URL] free domain names. I'm aware that this service requires renewal or activity at least once a month and as far as I know this is up to date and working OK.

Is this a router gateway problem? I suspect that port 22 has been blocked, but what could block this port? It's been working well for so many months. As far as I can tell the owner of the server/LAN has not been tampering with the router, so what could be blocking port22? I'm currently accessing the server using vnc4server.

Another really weird thing is that when I access the terminal on the remote server via vnc4server and I ssh back to the server using one of [URL] free domain names, it works! So as I understand ssh is accessing itself by going out of the LAN and back to itself. This would suggest that port22 on the gateway router is working. But when I try to ssh from a pc outside of the LAN, I just get timed out!

* openssl working from within the LAN but not outside of the LAN.
* sftp not working.
* domain name from dyndns.com working and up to date.
* Web server is working OK.

Networking :: Remote Server Maintenance Through HS Network?

Dec 12, 2008

I'm putting a new system in my wife's classroom that I would like to be able to maintain remotely. I won't be able to ssh into the system becuase it is on a highschool network that I have no control over. I have a VPN running at home so I could setup the system to connect to that, but I'm not sure how reliable that is plus I will then probably have to setup two NICs so that the system can also be present on the school network. Seems to add complexity and possible problems.
Are there other options here? I will do the research, I just need a starting place.

Ubuntu Networking :: Bash Script Over SSH On Remote Server

Dec 8, 2010

I've been trying to set up guake to automatically open 2 programs in two different tabs via ssh on my remote server. I have succeeded in doing this, however whenever the last command is run the terminal tab locks up and I can't enter any input, the only command that works is ctrl+c to kill (in this case) iptraf. I think it might be something to do with how I'm sending my ssh password using echo and pipe. This is my script:

Code:
#! /bin/bash
# script to launch multiple guake windows on Network21 local server
guake --rename-tab=Htop21 --execute-command="ssh -t 192.168.1.137 'htop'" &
sleep 5 &&
guake --new-tab=2 --rename-tab=Iptraf21 --execute-command="ssh -t 192.168.1.137 'echo password | sudo -S iptraf'" &

The first and second commands always work, whilst the last one loads iptraf then the cpu maxes out and i can't enter anything unless I kill the program. I've also tried nload and a couple of others, with the same results.

Ubuntu Networking :: Administer A Server From A Remote Network?

Jun 27, 2011

I have Ubuntu 10.4 Server, it's a local intranet server in back of a router in a "standard" home network. As I understand it laptops, PCs and the server are "hidden" from direct contact with the internet by Network Address Translation [NAT]. The router is a Linksys WRT54G all clients are connected to it, and the router itself is connected to a modem provided by the ISP. The server was given a static IP address. To admin the server I connect from a local client with SSH and get a command-line.

Is there a way to admin the server if I am a thousand miles away from this local network? Putting it another way, Is there a way to "tunnel" through to the server, give the user/pw and get a command-line from the internet? What software or hardware is needed?

Networking :: CUPS With Remote Print Server - D-Link DS-802

Dec 6, 2010

I have Rechat FC4 with CUPS 1.45 and a Dlink DS-802 Print Server.

I have installed CUPS, and pointed it at the DS-802,
but no joy.

Windows already prints to the 802 via a W2k3 server, so that works fine. FC4 with CUPS seems to point at the 802 but print jobs from localhost (just go to the print queue, and there they stay.

Windows continues to function fine, but linux wont send to the 802. Also, if Windows users try to print to the CUPS shared printer, it shows "No Accesss".

Networking :: Allow Remote Access To Server Running On User Account?

Jul 11, 2010

In the past, I've installed Internet services as daemons and as xinetd.d with no problems. Those approaches do not meet my needs. And, perhaps, nothing will.

- the service was converted from VB-6 to wxPython. It has a GUI which is accessed with either "remote desktop" or VNC.
- the wxPython service works on Windows and can be accessed from other hosts on my LAN
- the wxPython service works on CentOS and Fedora, but can only be accessed from within the server host. Even from other user-ids. But, I cannot get to it from other hosts.
- ipchains AKA firewall ports are marked for INPUT.
- The server host uses autologin to fire up a useid in group "user". I do not want it running as "root". the .bash_profile fires the service up.
- the service is heavily mult-threaded, and supports devices connected to serial ports asynchronously with the ephemeral port threads (all this works).

There are some programming solutions that I would rather not develop.
- a proxy service that runs under xinetd.d.
- separate the GUI code from the Internet and serial port code. Allocate a "control" port for remote GUI control. a'la SAMBA & SWAT

Is there any hope, that I can run it as is, by doing some network configuration stuff.

Networking :: How To Redirect Locally-generated Packets To Remote Server?

Mar 22, 2010

I'm trying to workaround a limitation in a server application. The limitation is that I can only connect to a LOCAL mysql database. I am trying to fool the server in to using a remote mysql database. I was hoping to do this by simply forwarding 3306 to another server on the same subnet.To that end I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.

Ubuntu Networking :: Configure Wireless PCI NIC In 10.10 Server?

Nov 12, 2010

I've installed 10.10 server edition on a box I just want to use for file storage/backup, uPnP server, etc. The area I need to put the box doesn't have ethernet as an option so I'm trying to get this wireless NIC configured. It's a Buffalotech WLI2-PCI-G54S which runs the Broadcom 4306 chipset. I've managed to get the drivers for the card installed via the instructions here: [URL]

The drivers are working properly as I can run

Code:
iwlist scan

and see all the wireless networks it detects. I found the info here: [URL] to complete the configuration, but I'm still unable to get it right. My wireless router is configured to use WPA2-PSK with AES. I could just try installing gnome and get the GUI network config, but would like to avoid that if possible.

Networking :: Configure To Use A Specific DHCP Server?

Jan 24, 2010

This is probably an odd request, but figured I'd ask in case someone knew. We have a lab that has the IP range 172.10.0.0/16 (255.255.0.0). The lab gateway/DHCP assigns an IP in the range of 172.10.0.2-172.10.0.254. I want to set up my own DHCP server on a specific range, for example 172.10.10.1-172.10.10.254. I create a new host fine, but since it's set for DHCP, it uses the DHCP server at 172.10.0.1. Is there a way to force it to use a different DHCP server on the client side? I realize that I can work around this with exclusions on the 172.10.0.1 DHCP server, or use iptables to deny DHCP requests to specific MACs, but wanted to know if there was an (easier?) way to configure the client to use the 172.10.10.1 DHCP server instead of the 172.10.0.1 server?

Networking :: Configure A Server At Home On Ubuntu 10.04 ?

Jun 29, 2010

I try to configure a server at home on Ubuntu 10.04 (French Server)

I have 3 network :

eth1 for lan (IP FIX) 192.168.1.100
ppp0 for a vpn connection on an English Server (IP DHCP)
tun0 for openvpn i use it to connect to my French Server from Anywhere

I draw it here

My problem is when i activate my ppp0 connexion i can't connect tun0 because all port are redirect on ppp0 connexion (i can connect only when i'm on the LAN)

OF course i redirect the port of my IP Public to my French Server IP Private. If i don't activate the ppp0 connexion i can connect to my server with tun0 connexion from everywhere !

So i try do this redirection but it's not working and i don't no why ???

Code:
### Routing acces openvpn et vnc de la connexion ppp0 vers eth1
sudo iptables -t nat -A PREROUTING -j DNAT -i ppp0 -p udp --dport 1194 --to-destination 192.168.1.100
