Hello, this problem is perhaps not realy security related, but I know that here are a lot of competent people, at least to give some hints for other sources of help. ;) When accidentally someone prints binary data to stdout (in a xterm) for example "cat image.tif", a connection to the lpd-daemon is established, and the printer prints a lot of nonsense. Especially in the case of a printer in another room, this can be nasty, when you realise after an hour that 100 useless pages are printed. It depends certainly on the binary you send to stdout, but with a huge tiff or something like that, it should be reproduceable. Thanks in advance for any hints, Peter P.S.: Some system specifications: lpd invoked by inetd (lpd from plp package) SuSE-6.x system (x= 0-2) -- ************************************************************** URL: http://gmv.spm.univ-rennes1.fr/~peter/ -Powered by LinuX- **************************************************************
