It's quite possible, with support from the original application. But when the original apps help, you'd need some cunning kernel magic to "swap" process ids (which would come with lots of kernel table entries, etc.). Hmmm, unless the bit of code you want to switch is part of a DLL - then you may be able to mmap the dll and hand-modify the code. Hmmm, thinking about it, you could do the same with a vi /proc/... Lots of ways, all tricky, but possible. Dom -----Original Message----- From: Craig Holmes [mailto:Leusentat_private] Sent: 23 September 2001 04:08 To: pen-testat_private Subject: binary switching, no killing Hi Listmembers, Me and some friends have created a small irc network in which we are implementing ssl encryption between client and server. Our original ircd did not have this feature and now our new ircds do. The problem is in upgrading, the whole ircd must be killed and a new one started, which causes all clients to drop. My question is, is it possible to almost "hijack" a process, and switch the binary without losing the pid & tcp/ip connections? Is this a crazy and impossible idea, or has it been done? Any help would be appreciated!
