(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.

Nietzschean · 18-01-2005 12:10am

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 12:15am

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 12:28am

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

Nietzschean · 18-01-2005 12:39am

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

PrecariousNuts · 18-01-2005 12:47am

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 1:05am

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 1:17am

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

PrecariousNuts · 18-01-2005 1:27am

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 1:37am

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

Nietzschean · 18-01-2005 1:45am

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

PrecariousNuts wrote:

add the line
syntax on
~/.vimrc

PrecariousNuts · 18-01-2005 1:58am

does that only work with gvim?

Nietzschean · 18-01-2005 2:06am

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

PrecariousNuts · 18-01-2005 2:15am

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

Nietzschean · 18-01-2005 2:15am

try it on turing

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

PrecariousNuts · 18-01-2005 2:24am

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

PrecariousNuts · 21-01-2005 9:37pm

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 12:59am

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 2:07am

ah yeah php is a complete doddle when ye know C

22-01-2005 10:17am

Really? Hmmm...

o yeah that, umm i forgot since eoin's gone i'm about the only one who can be bothered admin'n the mysql server..... woopsie

Nietzschean · 28-01-2005 9:46pm

right all done, check ur maths email.

PrecariousNuts · 28-01-2005 10:00pm

Thank you good sir! How did you manage to get to be (head?) admin anyway?

Kevin_rc_ie · 28-01-2005 10:02pm

lets just say he gives good. damn that was too obvious.

i'm not head admin anyway, its more of a team effort...and emm cause i helped out quite a few times n i guess showed i knew stuff so let me be admin n i learned everything else

PrecariousNuts · 01-02-2005 9:39pm

Do you have phpmyadmin? I know it's probably quicker and easier to manage from the prompt but it would be good to know it's there anyway.

umm globally installed no, tho i suppose i could install it without much hassle... you can of course install it locally(all it is is a couple of php pages really..)

PrecariousNuts · 02-02-2005 12:10am

Cool I'll do that then

Time Magazine · 05-02-2005 11:52pm

These threads make me wonder why people mock BESS.....

PrecariousNuts · 06-02-2005 12:19am

So having never used or even heard of VNC before that question, was I wrong in assuming that there was already a VNC server running on the maths servers?

Having exhausted google was I wrong in asking if syntax highlighting worked? I edited the .vimrc file so many times I got sick of trying to figure it out and just asked. (I had never used vim before either)

Was I supposed to know that ops@maths.tcd.ie dealt with creating mysql accounts? Did I know that Eoin was gone?

Go back to mocking BESS.
(Oh and that wasn't the original thread topic, it was edited. That's the only possible reason I can think of for you posting that comment.)

Uh that doesn't make sence, each user run's their own copy of a vnc server...

Did I know that Eoin was gone?

you were mailing poor eoin?
