Re: Locating bandwidth bottlenecks
please DON'T hammer down on DNS server to check your bandwidth limits - you'll disrupt the service of everyone else by doing so... the only way i saw for this so far, is by connecting to different ftp servers, and see what they give you. this is far from being ideal, though, since you don't know who is the limiting factor along the way. you could go with something similar to what 'flood ping' does (you'll have to hack the source, though, and make sure it doesn't overflow your connection). if you add this on top of traceroute's usage of the TTL field - perhaps you can devise such software. note, however, that it'll not be too useful, since this does not take into about QoS parameters set for different protocols on the routers along the way - so going via one port may yield a different result then going via another port... you're also not counting for packet loss - which can have a strong effect on TCP traffic throuput, due to the way TCP deals with retries. --guy Baruch Even wrote: * Gadi Cohen [EMAIL PROTECTED] [070215 17:14]: Is this possible?

By segment I mean the relevant variables of the process. Atomic code execution cannot be guaranteed at user level in a premptive multitasking system. However the system guarantees thread privacy. The only way to make things 'atomic' it to run the process with root privileges and switch the sheduler to SCHED_RR and assign it a high priority. Even so hw interrupts will interrupt it. So only kernel mode code can be 'atomic'. That or realtime extensions (which are equivalent to SCHED_RR in kernel mode).

recvmsg on dgram socketpair blocks on open socket?
Hi, I'm trying to help complete Shachar Shemesh' privbind project ( http://sourceforge.net/projects/privbind) and it mostly works except that when the writing side of the socketpair exits, the side which calls recvfrom keeps waiting for messages. I couldn't find anything which suggests that I'm doing it wrong. More details (the code is pretty small): privbind creates an AF_UNIX, SOCK_DGRAM socketpair to communicate between a parent and a child process. The parent then calls recvmsg(2) and waits for request from the child. If the child exits then the parent will keep on waiting on the receiving socket. I expected the recvmsg to return an empty message when the child exits but this doesn't happen. Explicitly closing the socket by the child didn't help either. What am I missing? Thanks, --Amos
