Start dragonfly on port 80

[kwmiebach]

I found a way to run dragonfly directly on port 80 on linux.



First I found out where the newlisp binary is:



$ ls -l `which newlisp`

lrwxrwxrwx 1 root root 14 Jun 26 23:37 /usr/bin/newlisp -> newlisp-10.3.4



This tells me that the binary is at /usr/bin/newlisp-10.3.4



I use the setcap command to allow binding it to ports below 1024:



$ sudo setcap 'cap_net_bind_service=+ep' /usr/bin/newlisp-10.3.4



Now I change the start script example-site/newlispServer so it looks like this:

Code Select Expand

#!/bin/sh

NEWLISP_REDIRECTION="./dragonfly-framework/newlisp-redirection.lsp"

if [ ! -f $NEWLISP_REDIRECTION ] ; then
        echo "ERROR: cannot find file: $NEWLISP_REDIRECTION"
        exit 1
fi

echo "If all goes well visit http://localhost in your browser"
newlisp "$NEWLISP_REDIRECTION" -http -d 80 -w . $*

I removed :8080 after localhost and changed 8080 to 80 in the last line.



Now the example site runs on http://localhost">http://localhost

It is considered unsecure to do this in a production environment, but for development it can be nice.
