I can set-up an ssh tunnel from machine A to Machine B:-
fred@my-linux:~$ ssh -P myport fred@myserver.homelinux.com
I can successfully logon to machine A to Machine B.
what address and port will my tunnel 'appear' on machine B? I want to send a stream back from B to A up the encrypted tunnel, not over the open network.
I'm know very little about Linux but decided to set up a machine running Drupal CMS on a Debian machine and it won't go. The folks at Drupal have tried to help but it seems the Debian OS won't do it's PHP thing for Drupal.
That means i'll have to start at the START I guess.

I have an SSH tunnel setup between a local server and a remote postfix relay VPS. This is so we can route all our outgoing mail through this SSH tunnel to a private relay VPS, this seems to give us much more consistent mail delivery than using our ISP's relay. So the SSH tunnel is set to route port 1025 on machine A to port 25 on the VPS This part of it is working perfectly and has been for months. However today I wanted to set our e-mail newsletter software (on the same network as the SSH tunnel start-point) to send through the SSH tunnel. So I punched in the IP/port... 192.168.1.5:1025 but it doesn't work. Is there something I need to do to allow connections from other machines on the LAN to access the start-point of the SSH tunnel? Or are SSH tunnels restricted to localhost connections only?

Internet and smb-browsing ON this machine work, as does pinging FROM it. If this was a windows machine, I'd say a firewall is in the way, but since it's a vanilla karmic install, this should not be the case (or should it?).

I am trying to establish the easiest way to share a folder from an Ubuntu machine to a Windows machine.In the past I have added things to smb.conf and that has all worked fine but what I am trying to do is to figure out what the "new user" way of doing this is so that when I am helping other people I know I am getting them to do the simplest thing.I completely removed samba and reinstalled it so that I didn't have any configuration. Right clicked on a folder and selected "Sharing Options" ticked the "Share this folder box" gave it a name and a comment and ticked the other two boxes.
When I went to the windows laptop then it kept asking for a username/password and nothing worked.Back on the ubuntu machine I did sudo smbpasswd -a [username] and created a blank password. Now from the windows machine I can access the shared folder.Is the smbpasswd step still required? It's very confusing for a new user as there is no suggestion that anything other than right clicking on the folder and choosing the options you want would be required. Is it something to do with the fact that this is an ubuntu machine that has gradually been upgraded through versions and this problem wouldn't have been there from a new install?

I have an issue with the manner in which Network Manager is configuring the network and short of ditching Network Manager I can see no solution.The issue : Getting a machine to update its machine name in the DNS serverSounds simple doesn't it I operate a FreeBSD based firewall / DHCP / DNS server, using a default Network Manager DHCP configuration the Fedora clients do not register their names with the DNS server when they obtain an address.
I have traced the communications with Wireshark and the Fedora clients are NOT supplying the PC's hostname as part of the exchange so this is NOT a DNS server configuration issue. If I uncheck the option 'Automatically obtain DNS information from provider' under the DHCP settings the Fedora clients DO register the hostname that is put into the Hostname (optional) databox. They do NOT however store the DNS server IP address or any other records defined by the DNS server.
Is there some hidden settings or is this a bug because it isn't acceptable 'DHCP' behaviour if it isn't possible to automatically set DNS server IP addresses and at the same time register the hostname during the DHCP negotiation. Before it is said I know I can use a fixed DNS IP address but am not prepared to long term, I am also not prepared to define the Fedora clients with a 'static' IP. I am similarly not interested in playing around with scripts or any other such 'frigs' to achieve what should be a standard activity - registering a host with DNS during the DHCP negotiation.
I need to access a Windows Server 2000 machine using a Linux machine via KDE, but that will migrate to Gnome. The Linux user to connect to Windows machine, you should open an application 'XYZ' automatically, and only this, denying any unauthorized access. When you close the application 'XYZ' communications (RDP?) Should be terminated. Do I need a log of accesses and possible attempts to circumvent the system and access other application.

I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable. I have configured everything fine but don't know why till now can't ping!
A. Windows machine settings as follows:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.
B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :
1. /etc/sysconfig/network:
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0

ONBOOT="yes"
BOOTPROTO="yes"
3. /etc/resolv.conf
nameserver 192.168.1.4

4. I restarted network service using this command:
/etc/init.d/network start
everything is fine. When checking using ifconfig command. I get the following:
eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0

I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0). I did everything above and can't ping till now, when pinging from windows or Linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.
I've run into a weird problem. Two of my linux machines (A and B, both running CentOS 5.5) are connected to the same wall ethernet socket via a hub. Bothf them are configured for static IPs. The trouble is that when machine B goes offline or hits a kernel panic, machine 1 goes offline too. What I've noticed is that in this condition the "route" output from machine A does not show any entry for the default gateway either The contents of /etc/sysconfig/network-scripts/ifcfg-eth0 for machine A are:

I have two Linux machines both running Debian (I do not want Windows to be involved at all). One is a desktop and one is a laptop. I desire to connect a not-yet-purchased printer/scanner combination machine only to the internal LAN via my router (Linksys WRT54G) via Ethernet cable, or via wireless if the printer/scanner has that capability. I want to be able to print to that printer (and scan from its scanner) by only having to turn on the printer/scanner and only one of the other computers, and not have to have both Linux machines turned on in order to print and/or scan.
So my questions are:
When I look at specific models of printers, what should I be looking for in their specifications that indicates that this configuration is possible (i.e., should I be looking exclusively for printers that say they are "wireless printers" or "network printers")?The reason I ask this question: In my online searching, I thought "networked printer" or "stand-alone network printer" meant just that, but what I found instead are pages and pages of instructions on how to connect the printer locally to a Linux machine, with the associated setup to allow that Linux machine to serve print requests coming from other machines on the LAN. And that approach is not what I want to do (with the notable exception of temporary setup to validate that the printer is responding to requests for printing and scanning from Linux).
Are there particular brands, makes, or models that I would have better luck in getting to work in this manner (i.e., "better stick with HP or Xerox")? Am I kidding myself that a combination printer/scanner would work in the same fashion and still be relatively easy to set up on both Linux machines without resorting to some Windows-centric approach? Result of my searching so far (I have not worked my way through all of these in detail, but plan to): References to local printer connection which is not what I want:
Setting_Up_a_Network_Printer_using_CUPS
Set up a network printer using cups
Set up a printer
The post inside Setting_Up_a_Network_Printer_using_CUPS that starts with "running an HP Photosmart 8450 as a stand-alone networked printer" (where is the permalink?) is as close as I could get, but I am concerned that the instructions given are specific to the HP Photosmart 8450, or specific to the HP vendor, versus for all printers that can be connected to an Ethernet network (not that being locked into HP is going to be a problem necessarily, but I would like to know why if that is the case). Linux compatible printers says "Have a look at LinuxPrinting for known working drivers for printers data base. Also buy from a linux friendly company, ie HP, Brother, Epsom." Later in that thread, someone said Definitely don't buy canon.
I have a ubuntu 9.04 machine i'm using as a file server. I'm able to see that machine from any XP machine, connect to it's shares play music, movies, work off of it NO problems. But i can't view the shares from a windows 7 home edition PC (garbage). AND, from the ubuntu PC, i can't see any of the other shares on network. I get "Fail to receive share list from server".
NOTE: Originally i had this machine connected with wireless card because of location. and I was able to see all shares then - both ways (still not from Windows 7 PCs though). However, when I moved to hard wire connection, the network disappeared. I've tried changing IP addresses, changing switches, but no network. I'd like to keep it hard wire. Can anyone point me in right direction or am i missing information?
I should preface this by saying I'm pretty much new to ubuntu. I was a nerd back when I used windows, so I'm fairly knowledgeable about it, but I lost interest right before switching to linux, so I haven't learned much past basic navigation.
I bought a WPN311 wireless card for my homebuilt machine a while back and still can't seem to get it to work. One person told me that after upgrading to Lucid it should work out of the box but that's not the case. It seems my computer doesn't even recognize that the card is plugged in. When I open the drop-down menu to choose which network connection to use, any sort of wireless option doesn't even show up.

All I know is that now that I have switched to Kubuntu the process has become much harder because now I have to find out some special locations, numbers etc. for it to connect to the printer. It's connected to a Windows XP machine on the other side of the house.
It says alot about 'contacting the network administrator' if I am unsure about what to put in. But I am more or less the network administrator. how to find out what numbers to put in so that my Linux machine can connect and print to the Windows machine? Or maybe someone knows a few commands to share? I go to Applications > Settings > System settings, Printer configuration, New Printer, New Network printer, and then there are a few options but I don't know which one to choose.
