Thanks. Is it possible that shred exit abnormally in any case (for example, some files that it relies on have been shreded)?

I need to securely wipe out a disk on a remote machine, but I don't have access to that machine. Therefore I cannot use the LiveCD+shred (or dd) combination. Besides manually shreding known data files, I am wondering if there is a (free) tool that can be used in my case. Thanks.
I hoping that you mean to physical access but you can make an ssh connection. If so, here are the steps. Note that you'll need to replace /dev/sdXX with the device of your swap part- ition and /dev/sdX with the device of the hard drive. It will run for several hours and leave you with a blank hard drive.
1) connect using ssh and stop all services 2) swapoff /dev/sdXX 3) shred -n5 -z -v /dev/sdX 4) echo 1 > /proc/sys/kernel/sysrq 6) echo o > /proc/sysrq-trigger
