I think that the problem is specific to 4.3.x. FYI dirk, I did the 'find /
- -perms +0002' myself, and php is installing a whole bunch of stuff with
world write, so this is a bigger issue than just the one script.

Take a look at the tcpmssd code in the ports/net collection. In a nutshell, the data that
is read from the divert socket contains the IP header, typically followed by the TCP/UDP header,
followed by the application data.

Subject: Freebsd 5.0-RELEASE & named pipes

Hi!

I installed FreeBSD 5.0-RELEASE (generic kernel).

When I try to direct stream to a named pipe, I get:

Resource temporarily unavailable.

[root@bart root]# mkfifo f; find /etc > f &
[1] 2200
[root@bart root]# -bash: f: Resource temporarily unavailable

???

Thanks,

Borut

Hi!

The system doesn't wait for me to open the reader, I get the message
instantly.

I worked on 4.7 & still does (also on linux, netbsd, ... :-) )

This is NetBSD 1.6

[root@himler root]# echo "test" > f &
[1] 2383
[root@himler root]# cat < f
test
[1]+ Done echo "test" >f

And this is FreeBSD 5.0

[root@bart root]# echo "test" > f &

[root@bart root]# -bash: f: Resource temporarily unavailable

[1]+ Exit 1 echo "test" >f

So, if I were to create the RAID-1 volume with atacontrol, I'm tied to
using the Promise controller? Could I move the drives to a
Highpoint-based controller or just a plain on-board ATA interface and
still have the RAID volume accessible? If I want this kind of
flexibility, should I move to Vinum?

Thanks again for taking the time to clear all of this up. I really
appreciate it.

Ok then you may want to either use 4.7, or upgrade to -current and see how it
does there. If you still get an error, the best place to ask would be on the
- -current mailing list. 5.0-release was not meant as a production release.

as an aside, yes Mike, I'll get the FAQ writeup to you.

This works fine on my system, which is -current from March 2, using both tcsh
and bash. But since bash is not the default shell, but a port, isn't this
dependent on the version of the port you have installed rather than the OS? I
have bash-2.05b.004.

bash-2.05b.004 here too. But -current might help.

Flood it with wire speed 64-byte packets and drive it into receive
interrupt livelock. Yup, the PCI bus is (most of) the problem here too.

If you want to boot from the array you need to have the array config
in a way that fits the controller, if thats not needed you can move
around as you see fit, you can even make ATA RAID's on any ATA controller
not just Promise or Highpoint as loong as you wont boot from it.
I guess I should make an option to atacontrol that can convert between
HPT/Promise format or maybe just silently write both to the disks ;)

Can't reproduce it. Maybe they fixed it in the 8100L rev.?

I tried a ping -f -s 22 to hit it with 64 byte packets. I also had
traffic going to the onboard gig and it wasn't impacted (granted the
source was a 100bit link tied to the gig link).

I'm running variants of -stable (FreeBSD 4.7 and later) on this hardware.

Subject: IP addresses of bridge interfaces

Greetings,

I recently upgraded a FreeBSD 4.6.2 bridge to 5.0, and am having troubles
with how it handles IP addresses.

The problem is that if the external interface is assigned an address, then
hosts on the same block can't access it. Likewise if the internal interface
is given an address, *only* hosts on the same block can access it! I have
verified that in both cases the bridge has its default route correctly set.

I won't be too suprised if this is due to screwey ISP routing, but I don't
recall this ever being a problem with 4.6.2.

Any tips?

thanks,

A quick look at sys/sysctl.h shows that there's a type CTLTYPE_QUAD, but
not SYSCTL_QUAD or SYSCTL_INT64 macro. You could add such a macro quite
easily though.
