(I guess Ian will be the only one able to answer this but here I go anyway)
How do I know what port to connect to on walton.maths.tcd.ie with VNC through PuTTY? I've got the option set to (under the tunnels section in PuTTY) L5900 localhost:5900. When I run VNCviewer it gives says: server closed connection unexpectedly.

I guess I'm forwarding the remote port 5900 to localhost:5900 then connecting to localhost:5900 with VNC. I'm pretty sure I've got all the right ports forwarded from my router so any idea where I'm going wrong?

There's not a huge amount of options in PuTTY so my last thought would be that I'm connecting to the wrong port on the maths servers.

probally are, when u ran vncserver what session number did it give u?
looking at namp i see sessions on 5901 and 5902

PrecariousNuts · 18-01-2005 1:15am

Oh right, I didn't realise I had to run vncserver by typing the command in PuTTY. I did that now and it gave me session 3. So that means I have to connect to port 5903 right? But do I have to start up a new PuTTY thing for that port?

PrecariousNuts · 18-01-2005 1:28am

Ugh still not working, I'm actually doing things right now but I'm getting an error connection refused

Nietzschean · 18-01-2005 1:39am

5903 seems to be a valid one , you sure you've the portforwarding setup correctly?

PrecariousNuts · 18-01-2005 1:47am

In PuTTY under tunnels:
Source port: 5903
Destination: localhost:5900

My router forwards ports 5900-5910 to my computer.

I try VNC to localhost:5900 and I either get connection refused or an unexpected closure.

just tried one there, works fine for me, you sure you selected local tunnel vs remote? and that in all connection settings available u selected ipv4?

In netstat I have:
local address foreign address state
davelaptop:5900 localhost:2397 TIME_WAIT

PrecariousNuts · 18-01-2005 2:05am

I guess it must be this retarded router

5900? should it not be 5903?

and once u can make an outbound connection your router doesn't come into it, vnc doesn't require an inbound connection................

PrecariousNuts · 18-01-2005 2:17am

Yey it's working now, I guess it was just that port thing. Thanks for pointing that out!

PrecariousNuts · 18-01-2005 2:27am

Two last things, is it possible to resize it to anything greater than 640*480 and does vi/vim have syntax highlighting?

PrecariousNuts · 18-01-2005 2:37am

vncserver -geometry 1600*1200 or whatever you want if anyone is interested

Nietzschean · 18-01-2005 2:45am

well since u figured the other one out.......

add the line
syntax on
~/.vimrc

PrecariousNuts · 18-01-2005 2:58am

does that only work with gvim?

Nietzschean · 18-01-2005 3:06am

ummmm nope, works fine with vim for me...

PrecariousNuts · 18-01-2005 3:15am

**** sake, another thing that doesn't work off the bat for me

Nietzschean · 18-01-2005 3:15am

try it on turing

o and try an echo $TERM and tell me the results there..

PrecariousNuts · 18-01-2005 3:24am

It works on turing... brought a tear to my eye. echo $TERM gives xterm-color

PrecariousNuts · 21-01-2005 10:37pm

Oh and do the maths servers have a mysql database or the likes? At the moment I have 4 or so very simple php scripts to read in stuff from text files and echo them and then the CSS takes over with the formatting. But they are very painful and seem to stop working and I don't like the way I have to set the permissions.

read in and echo? you could just use require/include and it would load up the files and spew them out...... , and 644 premissions? whats wrong with that if your going to be displaying them on the web anyway?

anyway yes we do have a mysql server, its on gosset, you can request an account by mailing ops@maths.tcd.ie

PrecariousNuts · 22-01-2005 1:59am

Great thanks, I'm pretty new to php so I was just trying to use the bit of C knowledge that I've got so far to do this since php is fairly similar to it.

Nietzschean · 22-01-2005 3:07am

ah yeah php is a complete doddle when ye know C

22-01-2005 11:17am

Really? Hmmm...
