i''m using the following probe to calculate how many bytes are being written by tcp write calls, by process and total: fbt:ip:tcp_output:entry { this->tcpout_size = msgdsize(args[1]); @tcpout_size[execname] = sum(this->tcpout_size); @tcpout_size["TOTAL_TCP_OUT"] = sum(this->tcpout_size); } I run this probe for N seconds. I suppose that if i get the

Hi all, I am installing a zone onto two different V445s running S10U4 and the zones are taking hours to install (about 1000 packages), that is, the problem is identical on both systems. A bit of trussing and dtracing has shown that the pkginstalls being run by the zoneadm install are making door_call calls to nscd that are taking very long, so far observed to be 5 to 40 seconds, but always in

I am doing some testing on the adjtime syscall, and I want to dump out the value of the kernel variable "timedelta", and I am failing at it. Some of my attempts got "Module is no longer loaded" and some got "Symbol table entry is not a data object" I found some info that dtrace can print out kernel global variable, so what am I missing here? -- blu "Remember

I have a clause that look like this: syscall::write:entry /execname == "ntpd" && self->recspec/ { speculate(self->recspec); printf(" fd=%d buf=%d\n%s",arg0,arg2, stringof(copyin(arg1,arg2-1))); } The ntpd program always write a \n trminated string in this context, so I used the "arg2-1" to drop the \n. This works

I have been doing some profiling using the profile provider. I have a command that runs more slowly on the T1000 than it does on prior systems and I am trying to find out why. Using the profile provider at 1000 hz, and aggregating on the ustack output, I find that the same function appears at the top of the stack on both platforms, but on each there are specific instruction locations within

Tried to start up tcptop_snv on snv87 x86 and got <i>dtrace: failed to compile script /dev/fd/11: line 168: conn_tcp is not a member of struct conn_s</i> Line 288 has this line: <i>this->tcpp = (tcp_t *)this->connp->conn_tcp;</i> which, after looking at line 168 of <a

Hi, I'm very interested in making SSH use UDP for large data chunks. Maybe you know FASP (https://en.wikipedia.org/wiki/Fast_and_Secure_Protocol), but that is proprietary, although the website says it's based upon open source methods. Is it possible to make openssh work with UDP for this purpose? Thanks in advance, Stef Bon

Any word on this update for CentOS 6?

Did find a solution to this? I am getting the same relocation errors. It seems rather odd that the relocation errors should refer to the directory that ndis is built in, rather than the one it is installed in. That doesn''t make sense, does it?

In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring" to poll the hardware and crossbow will wakeup this thread to poll packets from the hardware automatically. Does crossbow provide any method to disable the polling mechanism, for example disabling the this kernel thread?

Tracing Fans, I know it''s been a long time in coming but the CPU Performance Counter (CPC) provider is almost here! The code is currently in for review and a proposed architecture document is attached here for review. Any and all feedback/questions on the proposed implementation is welcome. Thanks.

Anyone know how to obtain firmware and starter .cfg files for Polycom phones? Despite registering at the Polycom web site, I can't locate this stuff.
