Hello people, Some time ago I've written a library wrapper for some Linux boxes in my university, which are doing some additional checks for system(..); and exec*(,...) libc library functions before letting them being executed. (since we are running a restricted shell there, and limit the set of binaries, users could run, by a system table). Some time ago we had some FreeBSD and BSDi servers installed, where we aim to give students an access. I tried to port my library to FreeBSD but I got stuck alittle bit with LD_PRELOAD functionality: (*) is there a predefined library name, which would be preloaded all the time, when a dinamically-linked binary executed? (on linux it's /etc/ld.so.preload) (*) Is BSDi compatible with FreeBSD here? (seems not quite, since whether I try to set LD_PRELOAD variable on BSDi machine, it makes no effect). Thanks beforehands best regards Fyodor -- fygrave@tigerteam.net http://www.kalug.lug.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
