Fixing Firefox/Iceweasel restricted port

Today I ran into this warning from iceweasel when I tried to access a web service on port 101:

This address is restricted

This address uses a network port which is normally used for purposes other than Web browsing. Iceweasel has canceled the request for your protection.

I found this article which said:

  • Open about:config
  • Create network.security.ports.banned.override if it’s not there
  • Set that setting as, e.g.: 101-104
  • Refresh the page

Security considerations for find

Read about the security considerations for find. Find is a *nix tool for searching though directories for files and filtering them to build lists or run commands.

While I’m here I might as well show you my latest find command, I think it’s a beauty. :)

sudo find . \
  \( \( \( \! -user jj5 \) -or \( \! -group jj5 \) \) \
    -execdir chown jj5:jj5 '{}' \+ \) , \
  \( \( -type d \( \! -perm -u+rwx \) \) \
    -execdir chmod u+rwx '{}' \+ \) , \
  \( \( -type f \( \! -perm -u+rw \) \) \
    -execdir chmod u+rw '{}' \+ \)
