I would like to set up a user account with no network access. Reason is that sometimes my little daughter plays with the computer (for example watching movies on dvd's) and I want to prevent internet access in case she plays unattended. Is there a simple way to do that? I am using ubuntu 10.04.
View 4 RepliesRunning Ubuntu 9.10 Ive just got my wireless connection working after first having got the wired eth0 connection working.
With the wired connection I could SSH into my server through my firewall/router (via a forward). I can run up VNC, from there firefox, browse the web - all is well.
I have now setup the wireless connection, using a static IP, and I can likewise SSH into my server. I can run up VNC. I can ping my router. I can log onto it via VNC. I can browse to my router. But I cant browse the internet.
But I cant ping google.com. The reason is there is no host lookup service. Nslookup eventually says no servers could be reached.
So specifically, if I ping www.google.com Im told "unknown host". If I do an NSlookup on it I get timeout, no servers could be reached. However if I ping 66.102.11.104 I get responses.
I see no relevant entries in my firewall log.
Unfortunately I cant traceroute because the package isnt found - and of course I cant install it because I have no internet !
Strangely (to me at least !) if I then tunnel through SSH and browse the web, I have no problems. It works ? I know I am browsing through my SSH tunnel because whatsmyip gives the IP of my router at home, not where Ive SSHd in from. I can surf just fine.
why I cant do host lookups any more (and this did work with my wired connection, but whether its related to my change to wireless, or static IPs or both I cant be sure - it certainly appeared to happen at the same time). And, more to the point, what I need to look for/do to rectify it ?
As a bonus Id be interested in why I can SSH and browse via tunnelling but not direct from my server (via VNC). Just for interests sake !

I am using wireless connection to access internet.
First off - I'm running 11.04 as a VPS on an OpenVZ.
I've set up a very basic environment of LAMP + mail server. Installing apache, php, mysql and proftpd all went fine, but whenever I install iRedMail (which is postfix + dovecot + clamav and few more packages) I lose the internet connection.
Although the server is easily reachable by ssh and http, I can't connect anywhere from the server. At first I thought it only had issues with resolving domain names, but now I see it doesn't even ping IPs as well.

I have a LAMP server running. Currently there are not vhosts, just the basic single site apache2 running a web app. I want to set up ftp access to the www root, but my attempts have failed. When I try to ftp using the user I created, I get dumped in the users home directory. I can also browse the entire file system. What I can't do is upload content to the www root. I get permission errors. How can I set ftp up to allow a user to access the www root only?

I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

View 1 Replies View RelatedI have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?
I have BIG troubles trying to set up wired internet connection in Ubuntu! To be able to connect to the internet I have to enter my MAC address, 2 IPs, netmask and 2 DNS address. When I try to edit the default internet connection eth0 with my correct information, the minute I enter my MAC address and save the changes the network manager creates new internet connection with wrong data and use it instead! I can't select the correct internet connection from the top bar where the internet icon is, because it is just not there. The only connection that I can choice is the new default one with the wrong data! If I try to create new separate internet connection with my correct data the same thing happens! The moment I enter my MAC address and save it, the internet connection disapears from the list of internet connections in the internet area in the top bar and I can't select it. I tried googling it, but with no luck I think that if I set up my connection trough the terminal everything will be ok

I have kubuntu 8.10 up and running however I am not able to get internet configured. this is on a laptop i re-purposed. I have ubuntu on a desktop that works just fine. however w/ kubuntu no such luck. i realize its just kde vs gnome and am connected to the same router and such so all should work just fine, but alas it doesn't.the desktop is configured using dhcp, not static IPs.
the laptop w/ kubuntu isn't recognizing eth0
>cat /etc/network/interfaces displays:
auto eth0
iface eth0 inet dhcp
after restarting and running /etc/init.d/network restart.there is no resolv.conf... i understand dhcp should auto-create this? furthermore running ifconfig desplays no results ?
Alright, I've been trying to get this fixed on my own, but I think I am missing a fundamental principle and no amount of scripts or hacks is gonna take place of that. I have adito/OpenVPN installed on my media center. It runs fine and I can access adito in my internal network from other computers just fine. But, the whole point is I want to be able to access it remotely!
Now, I had previously made a run at an external FTP site and failed miserably at that, and I think its all coming down to me not knowing how to configure my own router. I have a Netgear router, I can log into it and under Router status I can get what looks to be my routers external IP address. But if I try to access it at https://XXX.XXX.XXX.XXX:4433 (didn't want to use the default port, 443) I get nothing.
So, my main problems as I understand them are:
1)I need to clear the firewall on my router to allow traffic in/out of my reserved port
2)I need to forward incoming requests on that port to the static internal IP of my media center
3)I really would like a more reliable way to verify the info im getting from my routers admin settings page is actually my external IP, is there a command for this or a website that will tell me?
