I spent a little time recently thinking about what would be needed for
this and came to similar conclusions. The most interesting part is
implementing generic GASP receive. I think the nicest way of doing that
would be to implement a new network protocol for firewire, allowing
userland programs to do something like:

struct sockaddr_firewire a;
s = socket(PF_FIREWIRE, SOCK_DGRAM, 0);
a.sof_address = 0x12345000;
...;
bind(s, &a, sizeof a);
...;
len = recv(s, buf, sizeof buf, 0);

Internally, this probably means arranging for all asynchronous packets
to be DMA'd directly into mbufs and would probably change the firewire
code a great deal. Still, it might be worth it to gain a familiar
socket-based user api.

Obtaining Syslog message from a Cisco Router

[Edward Butler]

Hi,

I am new to this distribution list but wanted to find out if any one has
come across this issue before and could offer some pointers on getting
this started.

I am looking to dump the log files from various Cisco routers on to one
of various FreeBSD boxes we are running ( mainly FreeBSD 4.4 ) once the
logs have been dumped to then rotate these in a similar way that other
system logs files are rotated - dns, www and mail etc...

My question is - do I need to compile a specific syslog collector or
will syslog on its own be able to handle these messages? Also how can I
reconfigure logrotate to include these log files?

Many thanks, apologies if my questions are a little niave! 

Cheers
Ed

1) Tell Cisco routers to use a specific facility/priority for their messages.
2) Tell syslog.conf to place the messages using this facility/priority into
their own log file.
3) Tell newsyslog.conf to rotate these logs according to the desired policy.

No need to install logrotate. newsyslog is the default FreeBSD log file
rotation tool.

I use syslog-ng for this because it has some nice filtering options. 
One of which is source hostname/ip address. This means each router gets its
own logfile along with a messages file for all the routers messages.

Most of the engineers in the NOC tend to just leave this being tail'd in a
terminal as a handy way on watching for issues.

syslog-ng really is the way to go.

Re: defect onboard broadcom causing boot hang

[Bjorn Eikeland]

Descided to stick with the easy way, as its not a change needing adding
to the tree and I dont have any other bfe devices..
And surely the kernel says it's found a 4401 card when it boots, but:
bfe0:  mem 0xeb00-0xeb001fff at device 
9.0 on pci0
bfe0: Ethernet address: 80:00:80:00:80:00
bfe0: PHY Reset would not complete.
bfe0: MII without any PHY!
device_probe_and_attach: bfe0 attach returned 6

Thinking the chip is beyond "medical" help as even the MAC address is all
funny - ofcourse I could change that with ifconfig bfe0 ether xx:xx, but 
not
still of litte use without the phy :)

So I think I'll ask the hardware list how to avoid probing the thing at 
all.

Thanks for trying though!!

removing if_withname()

Bruce pointed out that if_withname is inconsistent about IFNAMSIZ.  I
was looking at it and cleaned it up, but then I realized that it is a
really inefficient implementation of ifnet_byindex(sdl->sdl_index).  It
turns out that it's also completely unused so I'd like to remove it
entirely rather then fixing it since it's both broken and pointless.  Is
there any reason not to do so?

I used glimpse and rwatson's fxr to verify that it's unused:

rl interface drops out occasionally

[Sumit Shah]

FreeBSD hackers,

I have a FreeBSD 4.9 server with Abit AT7 Max motherboard which 
includes a built-in rl network interface.  I've noticed that every now 
and then the network interface drops out.  I can ifconfig destroy and 
then create it again and the network interface comes back.  This 
machine serves nfs/smb/rsync exclusively and nothing more (2-3 gigs of 
traffic is moved per day).  Any ideas on how to track down what the 
problem is?  dmesg does not show anything unusual.

Thanks,
Sumit
PS Here is what ifconfig rl shows:

rl0: flags=8843 mtu 1500
inet  x.x.x.74 netmask 0xff00 broadcast x.x.x.255

I had the same description of problem. I shut off the onboard
NIC and installed a new rl and problem was solved. I spent several
weeks testing different things. For the 5 or ten bucks for a new
rl card, it is worth spending it.

Thanks, but I think at the packet rate I'm interested in (~30Mbit/s and more)

Re: Changing TOS of forwarded packets?

[Julian Elischer]

here's a suggestion..
I have not done this but it might work:

use ipfw to send sessions that match to a divert socket at port X.

use netgraph ng_ksocket to connect to the divert port you selected
above.

Use a variant of the node given to hack the TOC value..
(he's looking at ethernet packets where you would be looking at IP
packets so it won't work directly).  Hmmm having fiddled the packets
we'd need to reinject them to a socket..  we could reinject them to teh
same socket (we'd need to use a 'tee' node as follows:


[divert]<--->[ksocket]<>[tee]>[hack]\
  ^ |
   \|
/


OR 
you could open another divert ksocket

[divert]<--->[ksocket]<>[tee]>[hack]>[ksocket]-->[divert]

(the divert socket will always feed back into the IP stack.)

Re: Obtaining Syslog message from a Cisco Router

[Mike Tancsa]

And you might need to restart syslogd with a different start up param
so that it does not ignore messages from outside sources.

Re: rl interface drops out occasionally

[Sumit Shah]

Thanks for the reply, it's good to hear I'm not the only one 
experiencing this.  At least there is a simple workaround and we were 
going to upgrade the NIC anyway.

thanks,

I've noticed that
every now
and then the network interface drops out.  I can ifconfig destroy and
then create it again and the network interface comes back.  This
machine serves nfs/smb/rsync exclusively and nothing more
(2-3 gigs of
traffic is moved per day).
I had the same description of problem. I shut off the onboard
NIC and installed a new rl and problem was solved. I spent several
weeks testing different things. For the 5 or ten bucks for a new
rl card, it is worth spending it.
