Re^5: How to improve memory usage in this script??

This should work, and it's better than the forking idea because it keeps the dispatcher busy with monitoring at least $MAXCONCURRENT requests at a time. Let us know if you still have memory issues with this approach.

Re^6: How to improve memory usage in this script?? by Anonymous Monk on Feb 05, 2008 at 09:56 UTC
ok thx a lot for the script browseruk, thx for the fast response! ;). now when i run it it gave me an error "Can't "next" outside a loop block" so used while( ++$ips ){}; instead of the do(). now as for the memory usage, it now took a lot more. When at 10.0.43 it was already at 60mb and increasing.(remember that all i got so far is timeouts, so 60mb really is too much in my opinion) im interested in the fork method because of this "you can fork off one subnet at a time to a child process and its memory will get reclaimed when it exits.". so if i understood correctly, you would scan 255 ips with a child, then when done all thememory they used will get returned?. So, if the script takes 10mb scanning 10.0.0.0-10.0.0.255 the 10.0.0.0-10.0.1.255 scan should take aproximately the same??	[reply]
