Ubuntu Networking :: SSH Into Home PC?
Jul 29, 2010
So I have a PC in my office and at home. I can SSH just fine from my home to office, but I would like to go the other way. I am assuming that I have to forward some ports on my router. In the port forwarding section of my router I am given boxes named "port from" "protocol" "IP address" and "port to" I entered 22 for both port from/to, under protocol I put both tcp and udp and for ip address I put the local ip of my machine. Even with these settings I am unable to access my home machine from my office machine. Are there some more settings that I have to change?

I just got connected to Charter Cable Internet service a few days ago and I'm having a weird problem with my home network. Prior to this my network worked fine. On my network I have a desktop running Ubuntu 9.10/64 and Virtualbox with WinXP installed, an HTPC with Ubuntu 9.10/32 installed and a laptop dual booted with Ubuntu 9.10/32 and WinXP. The desktop and HTPC are hard wired to a wireless router and the laptop is wireless. The cable modem is hard wired to the router. I have samba installed and UFW is disabled. The problem is: with the cable modem turned off or on standby, all machines connect to each other and can transfer files, etc just fine but when I activate the cable modem all of the machines can connect to the Internet but the machines running Ubuntu can't connect to each other on the home network. If I boot the laptop into Windows, it can connect to the Linux machines just fine but if I boot it into Linux, it won't connect to the Linux machines but it can connect to the Internet and as far as the desktop, Ubuntu won't connect to the network but Windows running in the Virtualbox with bridged networking can connect to all of the machines.

I just started having a problem with my 10.04 laptop a few days ago, maybe Thursday, last week. When the computer is plugged into my home network (standard 192.168.1.1 sort of IPs) it works fine, but when I try to connect to my work network (130.15.90.XX) I am unable to pick up an IP. The router in my office is working fine, all the windows boxes can connect.
I've also noticed that when the computer is plugged in at work the notification icon for the networking indicates it is looking for a wireless connection (rather than the normal up/down arrows), even if wireless is deactivated
I can set a static IP in /etc/network/interfaces and everything works, so it seems to be a DHCP problem?

I can ssh into my home server via command line, from the terminal application of Ubuntu 9.10, but not from the Places -> Connect to Server... GUI tool.
The latter produces an error message box with two lines. The first reads "Cannot display location sftp://gabi@my_server_ip" and the second reads "Error reading from unix: Input/output error".
In my old Ubuntu 9.04, both the command line ssh and the "Connect to Server..." GUI way worked fine. The latter had the advantage that my server folders showed up in Nautilus. I liked that.

Problem: I cannot connect my Ubuntu 10.04.1 LTS PC with other PC's on my hone LAN... My PC will connect to everthing in my LAN using any other OS (Win7, Windows Vista, OpenSolaris), but not with Ubuntu.
I have a small home network. I have 3 PC's networked together into a Linksys WRT-54G Wireless/Wired Router. That router, in turn, is wired to a DSL Modem. This router is wireless and has 4 additional ethernet ports. 2 of the PC's are getting their internet connection via wireless, 1 via wired. There is also a wireless printer, a wireless connected PDA Smartphone and a PSP'. There are occasionally 2 other test Franken-PC's up on this as well. The Windows PC's are running Windows Vista and WIN7 and see and share with each other under the WORKGROUP Group.
My PC is multi-boot with Ubuntu 10.04.1 LTS Desktop, WIN7, Windows Vista and OpenSolaris (plus a few other OS'es)... This PC has 2 Ethernet Ports and a Wireless card. The wireless card works on this PC under the Window's OS'es... but maybe somewhat "suspect" under Ubuntu. (Has been since I started with Ubuntu 9.10.)
From any other OS on my PC, I can see other PC's and their shared folders, get into my router through a browser... From Ubuntu, I cannot. I can not even get to my router setup from Firefox! But using another PC, I can see the Ubuntu PC in the LAN router table. From that PC, My Ubuntu PC doesn't show up as a "PC" on the network- but when I tried to see if it was there by putting the IP address into a browser it said:
Code:
"IT WORKS!
This is the default web page for this server.
The web server software is running but no content has been added yet."
Ok, this is "different"...
I think the following are additional problems, but I'm still not sure they are related to my MAIN problem: When I boot or shutdown Ubuntu, I get "ath5k floor calliibration failure" messages flashing across the screen when in a text or tty mode. "ath5k" is the driver that the D-Link AirPlus Xtreme G DWL-G520 wireless card is using- But I can still get to the internet in Ubuntu by either Eth0, Eth1 or Wlan. Next, the other PC's are connecting to my router wirelessly to the LAN- My PC is connected ethernet.. If I try to connect to this via Wireless from my Ubuntu PC, it says it successfully connects, then less than a minute later disconnects. (on-off-on-off...)

What I want to do is, instead of putting the full Ubuntu OS on their computers and having to manage the parental controls on each, I am wanting to make a server that has the Full OS with both of their accounts and have them log into that server to access their desktop from a small client Ubuntu OS from their computers.
What software do I need and how do I need to configure it?
Edit: My home network hardware setup consists of a cable modem that is connected to a 8 port hub that all computers in house will connect to.

I have set up a FTP server in my home (FileZilla) and everything works how it is supposed to. I understand that port forwarding is required and can easily set that up. My question is what IP address do I use to connect to it when I am outside of my home network. Do I use the one my ISP gave me? And how do I figure out what that is? Could my ISP be using NAT that could be messing things up for me? Could there any other configurations that I need to perform ? Also do ISP's frown upon home ftp servers? (USA)

I have 4 machines 2 running Ubuntu 9.10, and one running windowsXP, and the forth will be Windows XP,only because some of my printer functions I can only get to work with windows, previous to upgrading to Ubuntu 9.10, I had everything working fine, my windows could see my Ubuntu's and my Ubuntu could see my windows, at that tine only had 1 ubuntu, now windows cannot see ubuntu and ubuntu cannot see ubuntu, my plan is to switch to mythbuntu , when I get things working, because I plan on adding 3 more machines, I have Gadmin-Samba installed on my ubuntu machines, do I need anything else. after upgrading to ubuntu 9.10, I had a system crash and had to start all over, this is just a home network with only one user.

First off, I should state that I am still using Hardy. I realize that it is many versions from the current release, but my schedule is full and provides little time to ring out a new distro and considering the nature of my problem I don't see much need.
The problem is that I cannot connect to my WPA home network. The wireless card is working because I can connect to any WEP network and before upgrading to Hardy I could connect, although not at first.
Have recently installed WICD which has not helped. WICD tries to connect but reports that it cannot obtain and IP address. Network Manager did not report anything but did seem to translate the password into an encrypted key (saw posts relating to this before but no obvious fix) Since switching to WICD I have not had the opportunity to test connection to a WEP network.
I do not wish to change the security of my home network to accommodate the operating system.

I installed the NFS functionality into Ubuntu 10.04, hoping to have a home file system. However, mounting it seems to be a challenge. When I mount on the server its self, it works fine. But on other computers. Such as my windows 7 machine, the connection times out. It seems to make the inital connect, then none after that. (The windows 7 machine does have the NFS files installed).

Ever since I had a hard drive that had an unexpected mechanical failure 2 years ago (& had to pay $1400 to have the drive pulled apart in a vacuum & copied), I've been understandably paranoid about ensuring I keep multiple up-to-date copies of my hard drive.Currently, I'm running 3 computers- The TV Computer, my Wife's Computer & my Main Computer. A second hard drive in the Main Computer & an external hard drive both act solely as backups for my Home folder. The TV Computer & my Wife's Computer also keep an identical Home Folder to my Main.I have ssh installed on all computer's & have made bookmarks via the Places Menu's 'Connect to Server', so obviously it's very easy for me to exchange files between computer's...
My problem is this; Every time I save/download/change a file, I have to copy it to 4 other hard drive's. It's kind of annoying.Can anyone suggest some ways for me to save some time with this? It's a wired network with static ip's. All 3 computers are pretty much turned on 24/7.I'm open to middle-of-the-night scheduled type of thing or whatever.

I currently have a desktop PC (running 10.04) connected to the home hub (v2) via ethernet and everything works correctly. I want to change to wireless so I can move the home hub, I've tried several usb wireless adapters and always end up with the same issue. I can associate with the home hub it will hand out an ip address, answer dns queries and allow me to connect to its web setup page but not the internet (ping, web, etc). I also have a htpc (also 10.04) which is able to connect through the wireless correctly plus a laptop running XP.
Desktop - Ubuntu 10.04 (gnome)
HTPC - Mythtv 10.04
Laptop - Windows XP
Wireless Dlink G132, Belkin f5d7050, edimax EW-7711UTn (currently in use) (Configured using wpa_supplicant)BT Home Hub V2 (Black)

one is whats the best way to connect to my home pc from another pc out there in the world? be on a windows or linux machine and remote into my home pc. Im using ubuntu 10.10. the other question is, i got a big family who aren't computer savvy at all. Is there a way to remotely assist them if they are on windows or mac. im looking for something similar to the windows remote assistance. With both users being able to see and control the desktop. with the hosts permission. something simple enough so it wont be a whole process to walk them threw to even get connected to in the first place.

As a user who is comfortable setting up a peer to peer network in Windows, how do I set up a simple peer to peer network with shares, on a standard network infrastructure (ethernet and basic dlink router), using Linux? I have two computers with Ubuntu 10.04, and would like to share files between them.Do I need to set static IP's? Why is only Windows network showing in Places/Networks?
Question two: I have 3 Windows computers (2 = XP, 1 = Win7) on my network, all with shares. When I try to access the windows shares from an Ubuntu machine, I can connect to some shares on some computers without being asked for credentials, however on other shares I am asked for credentials, but the credentials aren't accepted.I am assuming that domain = workgroup, so I enter in the workgroup name, but the dialogue refuses to let me in.

I'm wanting to set up a network. I'm still confused as to how to set it up. I think the easiest design is to have a switch on my border router.n this switch will be the servers. Also attached to this switch will be a Linux box. This will be a dedicated firewall. On it will be another switch. And the machines on the internal network will be attached to this switch. In the book "building Internet firewalls"(o'reilly) this set up is described as a screened subnet architecture. However the external interface on the Linux dedicated firewall will have to get it's I.P via dhcp (192.168.1.*) from the border router.
That or it can be a static I.P on the same subnet as the border routers dhcp range 192.168.1.*(but outside the dhcp range) but that would be trickier.The internal interface of this dedicated firewall would be static and on a different subnet as the external interface (192.168.2.*). Then this internal interface could give out I.Ps to the internal network that are on 192.168.2.*. If it did N.A.T for packets from the internal network then N.A.T would be being done twice; once by the Linux dedicated firewall and once on the border router, before going off to the net.Or is it a better approach to NOT do N.A.T on the Linux firewall and have all I.Ps on the whole network assigned as static(outside of the border router's dhcp range, but all on the same subnet(192.168.1.*))?.
Basically is there any point in the Linux box doing dhcp and N.A.T for hosts on the internal network?. I guess the answer is no. But i just wanted to hear your opinions, if you have the time. The border router is a home router. nted to have a normal triple-homed dedicated firewall and put it in the border router's DMZ but it proved unpredictable and tricky. So i just wondered what the best I.P addressing scheme would be for my newer way.

I just set up an old PC as an Ubuntu Server. I've got it all connected, and set up the way I want it...here's the problem I can't access my server as long as I'm attemting to access it from my home IP. I can ssh and ping it from both my phone on 3g and another (non-local) server I have SSH access to. Because of how our apartment is set up, each bedroom has it's own separate ethernet connection. The one in the room next to mine goes unused so I set up my server on it. My ISP is Charter, if that matters.

I'm having some difficulties setting up my ubuntu home server. I have vsftpd installed on my server, and I am able to use it perfectly when I am outside of my home. However, whenever I attempt to access my server through FTP from my desktop, it does not work. The file in question will load VERY SLOWLY to about 8% then the connection will drop out.My desktop and server are connected to the same router, and I feel as though this may be the issue.or vsftpd in a special way to access it through LAN?What I am trying to do specifically is use Comicpress (a Wordpress plugin) to upload comics to my server, with no luck.

I have 4 computers at home: 1 XP, 1 Laptop w/ Win7, 1 Mac, and 1 Ubuntu (hey, I like to try most everything). Anyway, I'm wanting to set up a home server to save everything on so that I don't have 3-4 copies of one file floating around. I was planning on using Ubuntu because I've always heard that Linux is a good system for a server and that Ubuntu is one of the easiest to work with.
Anyway, I just installed the Ubuntu OS, and the only software that I installed with it was Samba (I don't have a printer hooked up to this computer). Is samba the best software to use for this, or is there any other option that would be easier to use? I've heard that with samba there are a lot of things you have to change using the CLI (something about chmod, whatever that is, and others like it), which doesn't bother me, I've used CLI since the years before Windows, good ol' DOS.

I have a home server that I have setup to connect to via SSH. All is working well with that. I would like to have the home server access the internet through a VPN. However, if I do this, I am no longer able to connect to the server via SSH, even though I know what its IP address is.

Printer sharing on my Win home network.
The problem is it won't. I have an Ubuntu (11.04) computer cabled to a Belkin wireless router. The Brother printer is usb connected to the Ubuntu box - there is no problem printing directly. However, I need to print from a separate wireless connected Win7 box to the printer on the Ubuntu box and this does not work.
The Win7 can see all other Win computers on the network, but not the Ubuntu. Answers at my level gratefully received (eg: it took me two weeks, many hours and 3 re-installs to get dvds to play on Ubuntu 10). Current printer sharing information on the internet is either hopelessly above my head or outdated.

I'm running Kubuntu 11.04 .I want to mount my home dir on another machine and log in to the remote machine with the same username and home dir. The problem is that the files on the mounted dir belong to userid 99 (nobody). For example:
on the local machine:
Code:
[erezz@erez-lx:~]$ ls -ln ~/.bashrc
-rw-r--r-- 1 1000 1000 1644 2011-07-20 13:56 /home/erezz/.bashrc
on the remote machine:
Code:
[erezz@remote_machine:~]$ ls -ln ~/.bashrc
-rw-r--r-- 1 99 99 1644 Jul 20 13:56 /home/erezz/.bashrc
Here's what I did (and worked great for me in Kubuntu 10.04):
local machine:
/etc/exports:
Code:
/home/erezz/ *(rw,insecure,sync,all_squash,anonuid=1000,anongid=1000)
(also tried /home/erezz/ *(rw,insecure,sync,root_squash))
local user:

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

I have a dual-boot macbook with an OS X partition and an ubuntu partition. When I first installed ubuntu, I changed my home folder to my OS X home directory to synchronize all my files from both. My home directory is now /media/sda2/Users/username/. In a regular home folder, the icons for Documents, Music, Pictures, Movies, etc. are different (not just with emblems, but actually different icons). But when I changed my home folder, these subfolders' icons stayed the same as regular folder icons and I can't figure out a way to change that default setting. I know how to change the icons for each folder manually, but these changes don't appear everywhere (i.e. nautilus, places, etc). Furthermore, every time I change my icon theme, I would have to manually reassign icons for these folders. Is there a way to globally change the folder icons for these folders?

I was previously running 10.04 32bit. Recently upgraded my cpu/ram, so figured I'd try 64 bit. On my previous setup, I had / in one partition, /home in another, plus a few other partitions (/backup, etc).
I did the install of 64 bit, but was too scared to point /home in 64bit to the previous /home. After the install, now all those previous partitions/mounts are on /media. I'd like to just point /home at the previous partition. Should I mess with /etc/fstab to do this or will it cause problems? Is the easiest thing to do reinstall, then point the new install to use the pre-existing /home? Wasn't sure if that would cause problems or not. I've backed up most of the previous /home area, so worst case, if it gets blown away, I should be alright.

I need to specify a different path to home directories on a particular server than what LDAP contains for the users, besides using a symlink. E.g. "/Users/jdoe" vs "/home/jdoe" I don't want to change the actual LDAP attributes, just want a particular server to point them in the right direction (Ubuntu 10.04).
I'm assuming it's something I could probably set in pam configurations?

I'm new to Linux and Ubuntu 9.10. I have installed Ubuntu 9.10 on an older Compaq Presario 6100. Initially my built in wireless was not working. I searched the forum and was able to get my wireless working (I think) by installing the BCM43XX driver. I assume that works on my computer since I believe the BCM4306 driver is needed. Anyway, assuming my wireless is working, my home network does not show up in the pick list when I go to network<wireless.
I've spent a couple of hours already researching this and up someone can help me out. I would really like to give this new system a try.
