Also, sometimes you're in an environment where you can't change SQL*Plus but you have execution privileges and access to Oracle. You can use LD_PRELOAD in the same way as I showed here to override the program name. @Pete

Nice work Slavik, cheers Pete Hi Slavik,

I guess I am confused but why not just rename the binary if you want Oracle to think its not running what it really is running? – I talked about the same issue for a different rewason 6 years ago in this paper – http://www.petefinnigan.com/news_letter_001.pdf and interestingly in 8.1.5 i was able to modify the string for SQL*Plus in the binary using a hex editor from SQl*Plus to SQL~Plus so that the PUP functionallity didnt recognise that the binary actually being used was SQl*plus as i found that simply renaming it didnt work.

Nice work Slavik,
