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?

Guys, OK, now that we have the new core contributors squared away, we can go back to finishing the contributors list. There were some people who got added and then there is existing contributors list. I think Darren''s suggestion to wait to add new core contributors is fine (let the new constitution settle down and we can in the meanwhile have a more inclusive look at both rather than

Hi All, I have bfu''ed to net-virt_xb-21_snv_81_021308. The dladm command on my machine does not have create-etherstub option. Please let me know what could be the issue. Thanks Khushal

How do I create a vnic that represents the factory assigned MAC address of my physical nic? The bge device in my system (x2100) appears to support 4 MAC addresses. The driver reserves the first as the ''primary/default'' address and allows manipulation of the other three via the MAC_CAPAB_MULTIADDRESS interface. I''d like to use vnics on this system, as I have Xen guest

I''m running a nevada b99 guest on a nevada b99 host. The guest is configured as a dhcp client. When I snoop in dom0 while the guest boots, I see two back-to-back DHCPREQUEST packets issued by the guest. The first of the two packets has an empty UDP checksum; otherwise they seem identical. Is this a bug? Fred Oliver ETHER: ----- Ether Header ----- ETHER: ETHER: Packet 246 arrived

Dear dtrace Experts, I have seen some dtrace utilities like opensnoop and execsnoop etc. My interest is to write a simple script that can snoop the files which uses the 3 syscalls like open,create,unlink. I have gone through dtrace oneliners that can do the same : dtrace -n ''syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0));}'' dtrace -n

How come snoop doesn''t find the vnic0, by default: root at pine:~# ifconfig -a lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 vnic0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 10.9.59.56 netmask ffffffe0 broadcast 10.9.59.63 ether 2:8:20:7f:a9:16 lo0:

Hi , I have posted DTrace script to snoop tcp traffic and also provided a wrapper script for it to filter out unwanted traffic. http://blogs.sun.com/roller/comments/raviswam/Weblog/tcp_snoop_using_dtrace Please let me know if you have any feedback/comments on this. Thanks Ravi

Hello, I have the following problem: On a solaris 10 machine, with 5 "zones" there is a process that is talking to the wrong db server. I need to find out which process this is, so I can analize this further. I have tried to doing this using tcpsnoop from the DTrace toolkit, but without success. This is what I''ve done. First I started tcpsnoop, dumping it''s output

I sent this to Brendan but never got a response. Maybe someone else can help? ----- Hi Brendan. I''m trying to debug a problem where I need to snoop the network traffic over a punchin connection, where snoop doesn''t work. I found your tcpsnoop dtrace tool, which seemed like it might be able to do what I need. Unfortunately, it doesn''t seem to have an option to dump

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

I am quite unfamiliar with DTrace (and even more with Solaris/Linux/other) kernel internals. I recently had to help look into an issue where an application apparently sent a UDP packet, but it did not appear on the wire, nor did snoop(1)ing the interface show it, so the assumption is that it was lost (or misdirected) somewhere in the IP stack. We did use Dtrace with syscall::sendto:entry/exit to

I seem to be stumped on this one. I have TCP packets destined to my external interface from 127.0.0.1 (Ack+Reset zero data) with source MAC of my default gateway and I can't seem to block this traffic. Snort picked up the traffic and I have confirmed with tcpdump. So I decided I needed to examine my anti-spoof rules. I already had this one deny ip from any to 127.0.0.0/8 in recv

Hi I have a process which reads a socket using recvfrom. After sometime, for no apparent reason, recvfrom exits with an EINTR causing the sender to barf too. Basically the socket on which these processes were communicating no longer exists. On writing a dtrace, I could determine that a signal was received at that socket causing the EINTR. I do not know of way to see who sent the signal (which

Hi, I''m afraid I have some problems understanding how crossbow is supposed to work ;) On my machine (OpenSolaris, snv_111) I''m running VirtualBox with couple of linux / XP installation and additionally a zone with exclusive IP. My network configuration looks like this: [6]elsinore:~>dladm show-link LINK CLASS MTU STATE OVER bge0 phys 1500 up

Hi i''m trying to write my first dtrace script apparently i bit off a bit more than i can chew, i want to track io over sockets, i found your socketsize.d that gave me how to track writes, but i''m at a loss how to track reads, frankly i don''t see how your write tracker works because it uses a probe in a function that only takes two arguments but you grab size of write

I''m working on a case where customer has a 3rd party streams driver/module, called uplink, which sits over Sun''s ce driver. This 3rd party module is used by the telco to perform telco grade NIC failover. The customer was given an IDR ce driver, to avoid a panic they were given. The IDR driver was successful in avoiding the panic, but now the customer is getting many

We started seeing odd behaviour with clients somehow hammering our ZFS-based NFS server. Nothing is obvious from mpstat/iostat/etc. I''ve seen mention before of NFSv3 client dtrace scripts, and I was wondering if there ever was one for the server end, displaying top talkers, writes/reads, or locations of such to nail down abusive clients short of using snoop/tcpdump to nail down via

Hi all, I need to use asterisk to record all phonecall I have test using mixmonitor to record a call. Now I need to set the configure file to let asterisk auto record all calls. I have searched many document but still can not succeed. My version is 1.8beta and I prefer using mixmonitor. Regards!

FYI, I posted a blog a few days ago about a DTrace provider for NFS that is currently in development: http://blogs.sun.com/roller/page/samf?entry=a_dtrace_provider_for_nfs Let''s discuss any questions, comments, etc. here. I also advertised this on nfs-discuss at opensolaris.org. Naturally, I would expect the discussion here to be more on the specifics of DTrace, and the
