In .ssh directory, if there is a config file, ssh keys can be controlled by it.
For example, ~/.ssh/config would be
Host *.home.lan IdentityFile ~/.ssh/id_dsa.home User kbsingh Host *.vpn IdentityFile ~/.ssh/id_rsa.work User karanbir Port 44787 Host *.d0.karan.org IdentityFile ~/.ssh/id_rsa.d0 User admin Port 21871
id_rsa.xx is the private key.
First, you need to know your http proxy server. You probably have $http_proxy environmental variable in bash. Using this, you can specify the http proxy to git. It’s simple.
git config --global http.proxy $http_proxy
That’s it.
In order to make and install mathtex.cgi, latex and dvipng are prerequisite. You need to install latex first and divpng will come along with it.
You can follow the instruction
Following will show how I have done with it for example.
# wget http://www.forkosh.com/mathtex.zip # mkdir mathtex # cd mathtex # unzip ../mathtex.zip # cc mathtex.c –DLATEX=\\"$(which latex)\\" \\ –DDVIPNG=\\"$(which dvipng)\\" –o mathtex.cgi # cp mathtex.cgi /public_html/xxx.../cgi-bin/
For test of mathtex.cgi, in your web browser, you can do it by
www.example.com/cgi-bin/mathtex.cgi?x^2+y^2
It will give you the gif image showing equation by latex syntax.
* Note that this works with emacs 22.2 windows version.
Make sure that “(setq coding-system-for-write ‘utf-8)” should not be set in .emacs. If that, it will write it utf-8 always.
