maintaining the numerics website

Basic Information

The numerics website is hosted on a local Red Hat Enterprise Linux Server box (version 6.3).

The current hostname and IP of this machine at KAUST are:

hostname: lthcinump1 
IP:       10.254.8.113

Currently accounts have been set up for Matteo, David, and Aron. If you also need login access to this server please discuss this with David. Our IT points of contact are:

Khaled Hassan - khaled.hassan@kaust.edu.sa Stan Flachs - stanislav.flachs@kaust.edu.sa

Logging in

You can login to the machine with the following command:

ssh l-ahmadiaj@10.254.8.113

Alternatively, I use the following configuration in .ssh/config:

Host numerics
  User l-ahmadiaj
  Hostname 10.254.8.113
  ForwardAgent yes
  ForwardX11 yes
  ForwardX11Trusted yes
  RemoteForward 22821 localhost:22

This allows me to login directly using:

ssh numerics

It is also handy to remotely set up your public SSH key using ssh-copy-id, see man ssh-copy-id for more information.

Updating the Website

The website itself is stored as a large private repository in BitBucket. If David has granted you access to the website, you can access the repository at https://bitbucket.org/ketch/numerics-website.

You will need to tell Mercurial to trust other users from the apps directory. Create a file called .hgrc in your user directory and put the following in it:

[trusted]
groups = apps

You can update the website directly from the Bitbucket repository:

cd /var/www/html/
hg pull -u

To update the docs for PyClaw, NodePy, and RK-opt, you must build them locally on your machine (using Sphinx) and then copy them to the appropriate subdirectory on the server.

You can retrieve the repository while logged in to the numerics webserver with the following command. Note that the username and password should correspond to your BitBucket account.

curl --user ahmadia -O https://bitbucket.org/ketch/numerics-website/get/tip.zip

unzip tip.zip -d ~/sandbox
mv sandbox/ketch-numerics-website-2b3a33cfef7a/* /var/www/html
