Ubuntu Networking :: Different IP Address When Connecting To SSH?
Feb 5, 2010
I have often connected to my machine's remotely through ssh. Today I noticed that when I connect, the "last login" IP seems a little weird to me. I'm on my home network, so I connect directly with the IP of the computer within the router. But after the IP I get this XXX.XX.X.XXX.dedicated.neoviatelecom.com.br What is the neoviatelecom part? Is that normal? I don't remember ever seeing that there before. If I connect a couple of times from my win7 laptop (through cygwin) I get the correct IP address, but followed with the other part. If I connect with my other desktop (running Karmi 9.10) I get the same neoviatelecom thing as above.

I'm connecting to my wireless, but I can't connect to the Internet, not even via an IP address.
(*) Can not open web pages via IP address.
(*) Can ping internal hardware no problem.
(*) I can connect to the Internet via Ethernet no problem.
(*) I used to be able to connect via wireless on this computer. No settings changed in the interim.
(*) Several other computers currently connected & accessing Internet via the same wireless - no problem.
(*) Based on other posts, I disabled the avahi daemon, but this had no effect.
Outputs of some commands:

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

I was taking a peek at the active connections shown by the Firestarter GUI and noticed the following (the source is my computer):
SourceDestinationPortServiceProgram
192.168.0.11266.235.133.4280HTTP
I closed all Internet related apps and the connection persisted. After a reboot it did not reconnect (yet).The IP address appears to belong to esomniture.com - some sort of web analytics company. How do I prevent my computer from connecting to these rascals. I have found a lot of documentation regarding stopping inbound connections to services on my computer but not the other way. I have various filtering addons installed in Firefox however, this connection seems to be at a lower level as no program is specified as being responsible for the connection.

Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:

I'm running Ubuntu 10.10 and I'm having problems trying to assign it a static IP address. No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.

I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.

I have a few external IP's assigned to me by my ISP. I have IPcop as my router/firewall. I am wondering how to bind 1 of my external ip's to my internal ip address. So I do not have to port forward, etc. For Example, 77.77.77.77 to 192.168.1.123 and on the server it see's the external IP address.

I have a dedicated control computer that can only be accessed with web-browser (with its ip-address). My DHCP-server gives a static ip-address to the control computer (base on its mac-address). Somehow and after some time the control computer looses its ip-address (can't ping to it any more) ... and then I have to reset the control computer to get it to pick up the ip-address ... this is not a good solution since the control computer is not nearby. is there a way to force the control computer to renew its ip-address based on its mac-address

My security software has picked up multiple port scanning detections on my router/network and only the IP addresses are available. Is it possible to find out what the remote mac address is to see if the IP source has been spoofed? I've got a couple of different IP sources which were found scanning my ports.
I don't know if my IP and the remote IP address are on the same network or subnet for that matter which is the reason for my wanting to know what the mac address is to find out if its coming from the same remote machine.

I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.

I have one router, a linksys. It allows wireless and wired connections, as is normal. I have two XP machinesby wire to the router and three linux machines connected wirelessly. The XP machines both have IP addresses beginning with 192.168. while my three linux machines have IP addresses that all begin with 172. None of the machines is connected with a static IP address. All are automatic DHCP.I am told that the above scenario makes no sense. However, such is what I have so, I trust, the theory and the fact do not gel. I would not care except that I cannot see - using the nautilus network servers program, all of the XP computers with some of my linux boxes.

Forgive me if this has been answered, but searches have been un-fruitful. I recently built a 64 bit Ubuntu 10.10 pc. It is sitting right next to my Windows 7 Premium 64 bit machine. They can't see each other. I disabled Homegroup on my network. Now, when I try to access Ubuntu from Windows, I am prompted for a username and password. Both systems have the SAME UW and PW. It doesn't connect.When I go from Ubuntu to connect to Windows, I am prompted or Workgroup passwords.

I recently installed the latest version of Kubuntu in a dual boot system with Windows XP on a Dell laptop. The dell laptop has a broadcom wireless device, and I was able to set up the driver and get wireless working. Then I booted into windows XP to make a whole bunch of updates/driver installations, and when I booted back into Kubuntu it would not connect to the wireless network. I am pretty sure the device is still active, because it picks up on the wireless networks in the area. But KWallet does not open to ask for my password on booting. Something is not set right, but I can't tell what.

Situation: I can access Ubuntu from Windows XP but not XP from Ubuntu. When I try to access XP from Ubuntu I get message "Unable to mount location Failed to retrieve share list from server"
In System/Administration/Network Tools using Network device: Loopback Interface (lo) I can ping the IP address of the XP machine. Also, using Network device: Ethernet Interface (eth0) I can ping the XP by using its computer name.
In System/Preferences/Network Connections it shows under the Wired tab: Auto eth0 never used
Below are the settings in my smb.conf file.

A group I'm working with recently got new netbooks with Ubuntu Netbook Edition 10.04 and some AT&T LaptopConnect (3G) cards. When I hook them into the usb port, the cards light begins blinking, but nothing shows up to indicate ubuntu has recognized the new card, nor am I able to connect to the internet. My searches for help have indicated no one else has had any difficulty with this and that the card usually pops up and installs some drivers automatically or something.
I'm not sure at the moment the model of the 3G card other than very new, but I can check on that in a bit. The netbooks are HP Mini 210s.

am using win7 trying to connect to a ubuntu box using vnc. I managed to get it working for me with the full gui viewable. Then one of my housemates played around with some display settings for the backround and all of a sudden vnd only comes up with a terminal.
I went into terminal and attempted to start gdm and got this output
root@ben-desktop:/home/ben# gdm start

I have 2 computers in my house, on my network. I want to connect to one computer to the other using SSH. On one I installed "OpenSSH-server". "OpenSSH-client" was already installed. I go to the other computer to try to connect to the "server" computer and I enter in the terminal:
Code:
ssh username@192.168.0.33
It never connects. The text input "bar" keeps blinking, it never connects and I get the "Connection timed out" message.
how I can connect to the "server" computer? What am I doing wrong? And if I edit my "/etc/ssh/sshd_config" file to listen to port "12345" how do I get the other machine to connect to that port?
