Re: Remote SSH
I think that I may have figured out why my SSH over the 'net isn't working: I've been testing it behind my LAN. I just downloaded the Router Manual and it says (relating to port forwarding): "Please be aware that from inside your LAN you will not be able to access your server using its public IP address or name. On your LAN you will need to use its local IP address instead" I'll have to have a try from another location when I get the chance. -- Simon Ives E - [EMAIL PROTECTED] M - [EMAIL PROTECTED] W - www.simonives.info Please consider the environment before printing this email or any attachments. -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au

Yes - I use port forwarding to then send it on to the server to port 22. g. -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au

Within the router config I've exposed my file server's internal I.P address in what the router calls the 'demilitarised zone'. Basically, any ports I open in the router get forwarded to the file server. I've got port 22 open. I'm assuming that the file server is sufficiently exposed as Shields Up report it's host-name and that port 22 is open. -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
Re: Remote SSH
It would also be in your best interest to (at least) change the default port to something else besides port 22, http://www.securityfocus.com/infocus/1876 "Malicious SSH login attempts have been appearing in some administrators' logs for several years." "Then we examined who attacked the honeypot and what strategy these attackers used. There were 23 unique IP addresses involved in the login attempts. The attackers were more or less persistent in their attempts to gain access to the system, as shown in Table 3. Ten of the sources tried less than 50 combinations and then gave up. Five tried harder with approximately 170 login attempts, and eight tried even harder with up to 1450 login attempts." Changing the default SSH port from 22 to something else has seen the number of bots attempting to get in from several per day, to die down to zero. - IKT On Sat, Jul 5, 2008 at 4:16 PM, Simon Ives <[EMAIL PROTECTED]> wrote: > Can someone please help with the syntax to remotely SSH to my Ubuntu > file server.

Re: Linux Servers for Infrastructure
I'm trying to PXE boot a thin client that has a Vortex86SX processor (no math co processor or fpu) Error message: This kernel requires the following features not present on the CPU: 0:0 Unable to boot - please use a kernel appropriate for your CPU. any insights into the error code "0:0"? I'm guessing it has to do with math emulation and fpu emulation being required in the PXE image. Been looking for instructions on how to build a bootable image for PXE (onto an LTSP server) where I can enable both emulations but nothing simple enough for me to understand thus far. Any help appreciated. "You can just use cron-apt and your own apt-repo to deploy applications and manage updates, like Microsofts SMS but better. Using PXE and a customised image you could network boot and install all the machines as well, same as MS's RIS or WDS." -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
Remote SSH
Can someone please help with the syntax to remotely SSH to my Ubuntu file server. I've opened the server's I.P address and port 22 in the router and verified that this has occurred with Shields Up (it reported the server's host-name and that port 22 is open). I'm just unsure of how to SSH from a remote location. The syntax I've attempted is: ssh 124.171.***.*** (which is my public I.P address provided by my ISP) and ssh [EMAIL PROTECTED] Both return the following error: "ssh_exchange_identification: Connection closed by remote host" I can SSH over the local network with no problems.
