Opera with no ads is a utility that prevents the Opera browser from showing ads.
Opera connects to the website 18.104.22.168 to get its commercials.
I made a dynamic library that redefines connect, send, recv and select, so that I let Opera believe it does real accesses to the website 22.214.171.124. But I indeed return to it my own data, which is a link to my website with the text: Free as in "Freezer".
Of course, a problem of this approach is that the site 126.96.36.199 becomes inaccessible to you. But I don't think there is anything of interest there, so it's not a big loss. (If you really need to access this site, go and use some other tool or launch opera instead of opera.hacked.)
The code has been tested with opera 8.0 and 8.02 for Linux. If you have troubles using it, ask me, I may be able to help you.
You compile the program. Then, you copy libopera.so and opera.hacked in the Opera's directory. Then, instead of calling opera to launch the application, you call opera.hacked.
You should click Cancel in the Opera's starting screen that asks you the kind of commercials you want, so that the default "text commercials" remain in use. The other kinds of commercials seem to use different connections than the one taken over by libopera.
