ssh over port 443


Hi all

Want to get around my firewalling at work by running an ssh session over port 443. Then, using Putty I want to do a bit of port redirection and setup a VNC session to my linux box...

So the big question is, how do I change ssh to run on port 443???

Do you have a firewall seup at home? If so you could just forward port 443 to the machine you want to log into. That's how mine is setup. You can also change the port sshd listens on by modifying the config file (/etc/ssh/sshd_config on slackware). Change the line that says Port 22 to Port 443 and you are done.

btw, you don't happen to work at PC Club do you (443 is the only port we have open.)?

- Well you could uncoment the line in sshd_config that reads, "#Port 22" and make it "Port 443"; (this is the server not the client And configure you firewall to accept this port.

- You could keep it on the same port and use iptables to forward the ports to the correct ones:

But I don't think you have access to the sshd_config and iptables at work? And I also think that at work there is a secure webserver bound to that port already so you can't connect via ssh to that port.

I don't think you can have two services on one port.

Looks like he changed the setting on the server at work, if I followed this correctly? Did you remember to tell everyone else at work to connect on that port?

Heres my setup...

I run my a Suse 9 server at home thats sitting behind my own router on the end of a broadband connection...

At work, we only allow port 80 & 443 out to the Internet... So I reconfigured SSH on my Linux server at home to listen on port 443, opened up my own firewall to allow port 443 access to my linux server...

On my windows pc at work, I setup a putty session to redirect all localhost requests for port 5910 (VNC on my linux server) down the ssh tunnel and hey presto, I have SLOW access to my linux server for personal email and open internet access.....

Now my problem is that VNC is soooo slow. In the past I have run a Windows 2000 server at home and used terminal services from work to do the same thing. That was really fast & usable. VNC on Linux is sooo slow due to the way it renders the screen( I assume?).

Does anyone know of a way to speed it up?

Good job.

I would suggest not using a windows manager at all and simply ssh to your box at home and check email and download files etc. Or also just pipe the programs you use and not the whole desktop. Instead of "startx" try "thunderbird" for example or whatever you use for mail. It's way faster, well as fast as your connection.

You lost me... dont forget im a total newbie.... At the moment I'm the whole VNC session over SSH to work... As I said earlier, its SLOWWWWWW, very SLOWWWWW....

All I want access to is a bit of browsing and emial access to the IMAP4 server located in the Internet.

I am not running a mail server on my Linux box and I dont want to go that way either so How can I redirect my email/internet access to my work pc?

I'll try:

- Start an X server;
- Fireup a terminal; (putty)
- In the terminal type, "netscape";

Only the netscape app will run in you x server. All over ssh. Done'

You need an X server. I used to use "mix" when it was free.

Now your catching on. I would futher suggest installing linux on the laptop at work so you don't have to $pay or scour the net for a free x server. btw if you find one (free win x serv) let me know.
