msgid "$"

I reckon that this is a dollar sign as in the currency USD.

It would probably be much better if redhat-config-network could use the locale's
currency information than having it "translated". For example, some languages
are used in more than one country and are hence used with many different
currencies, so hardcoding a default like this in the translation is probably
very wrong.

With this code snippet I get the currency from the locale's information on the
console:

#--------------------
#define _GNU_SOURCE
#include <langinfo.h>
#include <locale.h>
#include <stdio.h>

int main ()
{
  setlocale (LC_ALL, "");
  printf (nl_langinfo (__CURRENCY_SYMBOL));
  printf ("\n");
  return 0;
}
#--------------------

You could probably use something similar.
