Ubuntu Networking :: Using Ssh To Connect To Computers?
Jul 13, 2011
I want to be able to access my desktop from work so I first set up a DNS. I can ssh into my own computer and using the ip address but when I try to ssh using my DNS (this is from my home wireless which is Linksys E2000), I get the following error:
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to ****.com [74.79.145.28] port 50000
debug1: Connection established.
debug1: identity file /home/andy/.ssh/id_rsa type -1
[Code].....
I set up the settings on the Linksys to accept DDNS but I am thinking there might be something else I overlooked? I do not understand completely what is happening to debug this. It seems like it initially accepts the connection and then something strange occurs.

- CAN connect to other computers - ssh and vnc over the home network (via D-link 524 router).
- CAN get an IP address via DHCP
- CANNOT get internet connections - including router at 192.168.0.1
- CANNOT even ping router (but I get an IP address - weird)
- Other computers on the network CAN access internet
- Live CD could not access internet
results of ifconfig

I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?
This is the results from dmesg:
Code:
I have tried:
- to set proxy settings as "Direct internet connection"
- disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer
- Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again.
- Uninstalled Crashplan which was the last software that we installed (and it was working ok).
I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).

I am using Fedora 11 all upgrades, wireless network WUSB54G network adapter. I can get to the internet but cannot get to any Windows (192.168.1.100) or Fedora 11 (...104) computers, printer (....101, 105). Here are the tests I have run.

I tried to connect two ubuntu computers via crossover network. But sometimes they can connect and see each other and even ping each other and sometimes not!
Each time, each of my PC's can ping it's own IP address but may not ping the other PC. I tried to disconnect cable, reconnect, disable network, enable it again, change IP address, disconnect via Network Manager Applet, reconnect and... . But when one of them don't want to connect I can't do this anyway!
Anyone knows what must be the problem? Sometimes it took about many seconds to get them connected, and sometimes they can't connect for many hours.
I must add that I have an ADSL modem on one of two Ubuntu PCs that connect via another cable.

I have 2 10.04 computers and one win 7 and one vista computer: The win computers can see each other and the ubuntu computers, but the ubuntu computers cannot see each other or the win machines. The ubuntu computers connect to the internet fine and can ping each other. I cannot find settings to correct.

I recently purchased a wireless USB dongle. It works great. I am looking to connect multiple computers to that USB dongle. I wanted to know if anyone out there knows if it is possible to link multiple USB cables together like a reverse splitter.

This is my first attempt at a server, and I running Ubuntu 10.04 server. I had to reconfigure my network, so now I am attempting to use it as a server. I have a Linksys WRT54G2 connecting various machines-- Windows XP, Ubuntu builds, and LinuxMint 10 Julia.
The long and the short of it is that the server connects to the Internet-- I can get updates and install programs via terminal. The server also connects to the router, as tested by pings. The client computers all ping back and forth nicely, and I can access the file share via FTP from the local side and externally (this is part of a larger network).
How can I get it so that my client computers can access the Internet through the router and server?

I have been trying to remotely access another computer (which is outside my local network) with ssh and have not succeeded. I've done everything I've seen nothing to suggest and as I opened port 22 on both computers, I have ssh configured so as to allow access from any computer (with password) and tried to log in using the external IP (the encounter with these online pages of "what is my ip"), I have a firewall turned off, the pc from which I agree is Fedora 14 that I want to access MacOS 10.5.8.
I need this because I'm running a very heavy program at the university that I can not run on my personal laptop, but do not want to have to go every day to college for this.

This may sound stupid but I've got to ask. Can I connect multiple computers running Ubuntu & run software from one computer from the other? I know how to connect using SSH & to copy files back & forth but I don't know how or if I can share programs.

I set up a server that has dhcp going. This works 100% as I get ipaddresses. My question is how do these internal computers connect to the internet? There is a proxy that needs to be passed as well...
Is this just a simple case of portforwarding or is this a completely different thing?

I have a samba share setup as the following. When I browse to it from PC's added to my AD domain, they connect instantly. When i browse to it from a laptop that's not part of the domain, i get prompted for login credentials. what credentials should I be putting in? I can't seem to figure it out. or is it because i have the workgroup set to what my AD domain name is, and the laptops aren't part of that domain.
path = /data/photos
browseable = yes
force user = pictures
force group = picturesgroup

I just recently constructed a computer to create a nice Fedora Linux server to replace a Mac Mini server that I have been using for a few years. I'm attempting to create a Samba share for my machines, a Windoze 7 machine as well as a couple MacOS 10.6 machines. I've set up Samba, started the service, allowed Samba in the firewall, and used system-config-samba to set up a share with a user. I created a User called "space", and a share /media/peliculas/Movies (a mounted hard drive). When I type in \IP_ADDRESS in the address bar in windows 7, I get the option to log in. I log in correctly and I see two directories "space" and "Movies." Unfortunately when I click on one of them I get the following error message:
Windows cannot access \IP_ADDRESSMovies Check the spelling of the name. Otherwize, there might be a problem with your network. To try and identify and resolve network problems, click Diagnose. I also get something similar when I attempt to connect with my mac machine. Using "Connect to Server" I type in: smb:\IP_ADDRESS, and login, I have the option to mount "Movies" or "space." If I select any of these, I get the following error message: There was an error connecting to the server "IP_ADDRESS." Check the server name or IP addres, and then try again. If you are unable to resolve the problem contact your system administrator.
Also, if I type 'smbclient -U space -L IP_ADDRESS' I can see the "Movies" in the "Sharename." At this point I'm not sure what else to do, and have been trying to figure this out for the last few days (losing sleep due to being baffled). The only thing that I can think of is that I have something wrong with the smb.conf file. Here is what it currently displays:
Global Settings
workgroup = WORKGROUP
server string = Samba Server Version %v
log file = /var/log/samba/log.%m
max log size = 50
[code].....
One last thing, when I check the log files, there are error messages that state: smbd/service.c:1009(make_connection_snum) '/home/space' does not exist or permission denied when connecting to [peliculas] Error was Permission denied --Windoze 7 and MacOS 10.6 log files

I have got three computers at my home[A,B,C] ( all connected to each other), now I connect to B from A using telnet( $telnet ip_B) , but when I try to connect to C using this telnet session( telnet > open ip_C) , I get this error, "already connected to xxx". Is it possible to connect A to B and then use that session to connect to C, so that C finds that the request is being asked by B.

I successfully installed Ubuntu 10.04 on 2 laptops (both are identical in terms of hardware). In addition, I connected both of them (using RJ45 cables) to a switch (just a switch; I don't have a router). Can anybody guide me what should I do / what settings should I specify in each laptop in order to be able to SSH from one laptop to another?

We have 5 computers networked with 9.04 installed. On some days, when you click on Place -> Network, then all the computers will show. On other days, like today, it does not show. However, one can ping them and I have been able to print to one computer which has the printer attached. SAMBA is installed on the computers for file and printer sharing.

I have a small home network. Computers A and B are both running Kubuntu Lucid. Computer A has an external USB hard drive attached, partitioned ext3 and mounted to a folder in computer A's home folder. Computer C is running Vista. I installed Samba, and computer C can access all the files on both computers A and B. But using Samba, computers A and B can't see each other OR computer C. That's not really important to me, but they can't
So I installed NFS and got computers A and B talking that way. I like NFS better. It's faster than Samba. BUT, computer B can't access computer A's USB drive, and I need it to do that. When I'm using computer B and I click on the folder the drive is mounted to, the file manager just shows the folder as empty.

I'm using Ubuntu on my laptop but I'm having a small problem. The network is working fine except for the fact that I can't reach anything on my LAN (can't even ping the router), but everything on the outside works just fine. I can even visit my webserver if I type my public IP.
Where should I begin looking for faults?
Here, enjoy some data. I'm using my wlan0 interface, not sure whether eth0 works or not.

Just to gain access to one of my computer across the house I use VNC a lot but the computer changes its IP address every so often that I refuse to just get up and check it. Without giving that computer a static IP address, is there a way to hunt down the computer's IP?

I have two desktop computers on the same home network and I am unable to share files between the two. Both have access to the network. One is able to file and printer share using SAMBA and a windows 7 laptop. The other machine is unable to either do file sharing via Samba or SSL file sharing between the two Ubuntu machines.

I'm having some trouble addressing computers by name. I've just upgraded most my my box's to Lucid, and it was all working fine, but suddenly stopped - not quite sure why, or what I did, but I need it to come back! At first I thought it was my old router dying (which it was) but a new router hasn't helped.
I've now moved DHCP from the router to my server, and that's working fine, giving out static IPs from MAC addresses, and so forth, but I still can't address anything by name. My server is on 192.168.100.1 and called myth-server, if I
