Ubuntu Networking :: Assigned Computer A's Static Ip To Computer C Without Changing Dhcp Setting?
Aug 18, 2010I set up a dhcp server in the lan and assigned static ips to two computers, computer A and B, according to their mac address. Everything was running fine. But when I turned off computer A, connected computer C to the network, and assigned computer A's static ip to computer C without changing dhcp setting. Computer C was able to access the internet. When I turned on computer A, dhcp couldn't assign an ip address to it, and computer C showed an error message of ip conflict and failed to use internet. I wonder if dhcp server is able to prevent other computer from using the same static ip that is already assigned to a computer according to its mac address.
View 5 Replies View RelatedUbuntu Servers :: When Is A Static IP Assigned At Boot
Oct 22, 2010I've been having a problem getting a couple of services started at boot on my home server. I want to have my Openvpn daemon and a holdingnuts poker server start at boot. Neither of these start properly if placed at level S99 in the rc2 folder. Looking through the logs, it seems that the network is not up and running at this time. To confirm this, I placed the following in my rc.local file that runs at level S99.
Code:
ifconfig | cat > /home/username/network-status.txt
My ifconfig file shows the lo, eth0 and my bridged br0 interfaces. However, the br0 interface does not show an IP, netmask or anything else, indicating that it hasn't been brought up, yet. So this begs the question, if you have a static ip set (with a bridged connection for the VPN server), when does that actually get up and running? I would have thought that it should be up by the time that the last startup scripts are running. How can I ensure that these things run at startup, but not until the network is fully up and running?
Ubuntu Networking :: Wireless Connection Drops - Access Point Not Assigned
Aug 19, 2010I have Ubuntu command line only installed on my HTPC (it is XBMC Live installation). Kernel is 2.6.31-16-generic. My wi-fi card is AW-NE770 from AzureWave (mini-pci on Zotac Atom motherboard). I have successfully configured wireless connection to my router. Unfortunately, after short period of time connection drops. When I restart /etc/network/interfaces all goes back to normal. When connection is dropped, iwconfig shows that access point is not assigned. I have already tried installing backport drivers, removing security on the network (WEP and WPA), assigning static IP or using DHCP. Nothing works. I know it is not the router or my internet because I can be at the same time on my laptop and that works fine.

Sep 7, 2010I 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 With Dynamic IP?
Jun 28, 2011I am looking for a way to be able to access my PC from a remote place. The problem is that I have a dynamic IP. I have registered at dyndns and have found settings in the router to 'Activate Dynamic DNS' and then you supply your dyndns address, password and tell it to update the WAN ip address automatically. This works, however only internally and only to the router as opposed to my PC I am not interestes in accessing the router to configure that remotely, only accessing my own PC.
Is this something I can accomplish with:
A ZyXEL P-660R-D1 router
A dynamic WAN IP address
A PC connected to the router
A static IP address for my PC
Ubuntu Networking :: Remote Desktop Access Refused
Feb 17, 2010I have 4 boxes on a local network: 2 with XP only, 1 with Ubuntu 9.10 only, and 1 with both. All boxes can share folders, set up with share-admin instead of using Nautilus right-click properties for each folder. I can see and control the remote desktops on all boxes, to all other boxes, from all other boxes,with one exception: I can only access the XP desktop on the dual boot box, not the Ubuntu desktop. When I try I get: "Connection to host 192.168.1.102 was closed." I am refused access to the Ubuntu desktop in this manner from both the other Ubuntu machine, and from both XP machines.
My setups are basically plain vanilla with routine installs of Ubuntu 9.10. On the XP machines I am using TightVNC on the XP machines to view both other XP desktops, and the Ubuntu desktop that is accessible. On both Ubuntu setups I am using (I suppose) vino and vinagre, and have completely re-installed what I think is the relevant software. There is no firewall running on the Ubuntu dual boot, when I check ufw. For reasons I cannot determine the inaccessible Ubuntu desktop is not providing its own address but instead in the Remote Desktop config dialogue it identifies itself as 27.0.0.1 which I think is the loopback id. I know so little about this sort of networking that I am not giving all relevant info, but I still thought I'd try.

Ubuntu Networking :: Mldonkey: Remote Access With Ip Limitations?
Oct 15, 2010Coming to the point, as per object, I'm playing ( read also as "messing up" ) with mldonkey since last weeks and I have managed to get it working correctly on my home network ( behind router and firewall ). Next step in my development plan was to enable remote access to mldonkey web interface from any external network, like for example a friend pc. I'm aware of the "IP Access Restriction" in the mldonkey configuration file (downloads.ini) but there I can only specify an ip ( or ip-range) to allow access.
So the question is: how can I manage to disable* ip restrictions upon access, so that with a DNS-aliasing service I can access mldonkey web page virtually from anywhere?
(*) = maybe this is not the correct word but it explains the concept.
Ubuntu Networking :: 11.04 / Cisco VPN - Cannot Access Remote Network IPs
Jul 8, 2011I have just installed Ubuntu 11.04 and the Cisco VPN client with :
apt-get install network-manager-vpnc
I have imported the PCF provided by my employer into the GUI. The group password also seems ok, when I login to the VPN server, I am provided with the "VPN Login message". (On Windoze, I get an Ok/Cancel popup with the same message). In Ubuntu, I don't get to click "Ok" but it looks like I'm connected properly. The /var/log/syslog file contains numerous static routes added, 30 or so. After the Login Message, I see the couple of line:
Jul 8 12:40:51 ubuntu02 vpnc[1613]: can't open pidfile /var/run/vpnc/pid for writing
Jul 8 12:40:52 ubuntu02 NetworkManager[630]: <info> VPN connection 'VPN to my network' (IP Config Get) complete.
I get an IP from the external network correctly as well:
tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:172.16.10.170 P-t-P:172.16.10.170 Mask:255.255.255.0
However, I cannot ping any of the machine on the remote network. None of the network services seems to be accessible. Why the machines on the VPN are not accessible?

So I am interested in Remote accessing my windows computer from my laptop and game Fallout on that(is that even possible) also, I really do not want anything to do with WINE so putting it on my ubuntu is not desired.I have basic knowledge of windows and even more basic of linux knowledge.So I can open the window for remote access.I even have the IP of my other computer.. It even recognizes the domain but pops up with this window when I try to click it.

Feb 23, 2011my g/f was able to access her jobs computers from home in Windows. she'd go start->program->access->connect to remote desktop... (or something like that) in any event, i've found some programs in Fedora 14 that say they'd do the same, however i can't get it to work. in "remote desktop viewer" i'm trying to use 'VNC' protocol,and trying to put the ip in the first of the "Host" lines.
now, there might be another issue, is it possible she need more info than the ones she got in order to use LINUX remote desktop? she has (what she has written down as) Computer # 111.111.111.11 and then ';' and 4 additional numbers, so (for the sake of the example) computer#: 111.111.111.11;2222 she has a 'username' and a 'password'.
Ubuntu Networking :: Remote Access Via Web Brower Over Standard Ports?

Does such a thing exist for this already? How would someone go about setting this up? I have a domain name and use dynDNS which works for certain tasks but I need another solution. Of course being behind a corporate firewall all the usual 'remote access' classification sites are blocked by bluecoat proxy and some cafes and wireless networks also block these sites

Apr 28, 2011My apologies if this is the wrong board for this thread, but seeing how the issue appears to be related to where I'm connecting from, I thought this would be the place to look.To start off, I've been running VSFTPD on the box for a good year or so now. Until recently, everything seemed to be working fine, but during the past few days I've run into issues with it and have been having trouble pin-pointing the problem. I've gone as far as reinstalling VSFTPD and rechecking every line in the conf file to no avail.The issue presents itself when I try to login to the FTP server remotely. The moment I put my user name in, I get disconnected without any error message, simply connection closed. That isn't the case when I'm connecting locally from the server.If I try to connect remotely using eth0 (internal network), it works fine again... but if I try eth1 (external network)... it fails. I'm thinking it might be related to PAM, but so far have been unable to figure out what I need to change in the configuration there. Additionally, the PAM log file doesn't show any activity if I'm connecting through eth1, but displays it if connecting through eth0.

Jul 16, 2010New Fedora 13 Install. I have Remote Desktop Enabled. I can access the machine from itself but not others on the network. I stopped the firewall, that did not work. I looked in hosts.allow and hosts.deny, no entries there. The vino server is running. There is nothing in /varlog/messages, dmesg or /var/log/secure, at least nothing I could find related to vino. What else can I check? The conf file in my home folder looks exactly like one on another machine where it is working. forgot to add the message I get when I try it from a remote machine is "The connection to host 192.168.1.100 was closed". So it appears something is actively rejecting the login.

Jan 10, 2011We have a fedora 10 server that the company connects to with other computers in the office. The file everyone access, public_share has no restrictions to the people that use it. We have another file, art_share that is password protected and everytime someone wants to access it they must login with it, but there are only 3 people out of the 15 that need to access it. Everyone needs to access public_share at some time.
My question is: is there a way to limit the permission for certain remote users to public_share so that they cannot write or execute, but at the same time allowing others full permission? I tried to do use chmod, but then it changes everyone's permission (I assume because of the remote access).
Networking :: Secure Remote Desktop Access?
Feb 7, 2010They are running Kubuntu. How to access their desktop from my home or office using Internet. Logically I remembered about kfrb and X11-vnc. But both of them need some approach to provide security. I'd like if someone could give me some pieces of advice on choosing the simplest and better approach:
To secure kfrb or x11-vnc is simpler or better to mount a vpn or to use an ssh tunnel? Is there any other solution? My pearents ISP use DHCP, so I think it would require some service like dyndns or similar...
Networking :: Remote Access To LAN When Public IP Is Dynamic?
Feb 4, 2010Is it possible to provide remote Windows users access to a LAN via the Internet when the LAN itself is connected to the Internet via a SOHO router that is assigned an IP address dynamically? An LQ thread from 2004 includes a suggestion to use VPN and DynDNS.com. Is that still a good solution? Are there any security issues?
Assuming:VPN is a good choice. DynDNS.com or similar can be used to give remote clients the public IP address of the SOHO router. the SOHO router is configured to forward VPN traffic to a Linux system acting as the VPN gateway. then, for a LAN of ~20 IP nodes and less than 5 simultaneous remote clients, are there any other VPN server software solutions to consider other than OpenVPN, Openswan and strongswan?
Ubuntu Networking :: Setting Up Desktop (9.04) Behind Router For Remote Access By Latptop (9.10)?
Jan 8, 2010Setting up desktop (9.04) behind router for remote access by latptop (9.10) I am setting up desktop (9.04) behind router for remote access by latptop (9.10). Rationale: All of my files are on my desktop HD, but I am often out of my home needing to work on my files. It is becoming labour intensive to keep track of the files I make/change and try to copy them on my non-connected desktop/laptop.
Dream: Able to remote access and modify my desktop files from my laptop (while the files remain on the desktop). Request: A simple, GUI, basic, non-technical guide how to set it up!
What I know: 1.I was going to use the 'Remote Desktop' VNC connection under System->Preferences. However, if I understand this correctly, this only secures my computer (i.e. Locks the front door of my desktop) and the data streamed between them is not encrypted.[URL]..
2.Then I need to set up my router to accept the connection from my laptop.
3.Then I will need to use SSH to secure the info sent between them. This is the bit I don't really have a good grip on.
