    tcp connection setup early disconnect

    We're running into an odd situation and I was hoping that someone might have heard of it. When attempting to set up either a SSH connection or an HTTPS connection with a Tomcat server, the socket gets disconnected during TCP connection setup. Multiple tries will eventually work. Packet traces...

    FIN Flood on loopback interface

    Outstanding! I will try this on one of our systems as soon as possible. We're using 8.1 at the moment. Thanks

    FIN Flood on loopback interface

    The only thing I've got at the moment is a really large application. I'll see what I can do to get something that can be used as a test program together. It might take a few days though. Thanks

    FIN Flood on loopback interface

    Anyone heard of this? Client and server are connected using TCP across the loopback interface. Both sides of the connection set their socket option buffer size to 64KB and SO_LINGER is set to 3 seconds. Data is transferred (< 1MB) and the connection is closed from the sever side. The server...

    DHCPv6 Support in FreeBSD 8.x

    I'm curious now. I rummaged around ports and found that ISC DHCP 4.x is in FreeBSD 8 and 9. Of course, there are no rc.d client scripts in these packages but I would guess that the upgrade from the current dhclient to a 4.x dhclient might be simpler than using WIDE dhcpv6.

    DHCPv6 Support in FreeBSD 8.x

    It appears to me that there is no support for DHCPv6 clients in FreeBSD 8.x. I guess I expect to see something like ifconfig_igb0="DHCP6" in /etc/rc.conf but I don't. Am I missing something? Thanks

    Java vs the BEAST attack

    I'm wondering if anyone knows what TLS revision OpenJDK 6 Build 23 is at? There is an exploit whose fix is to run TLSv1.1 and RC4 described here http://www.kb.cert.org/vuls/id/864643. Thanks

    Long pauses in getblk

    Thanks for the suggestions. Smart status looks OK and there are no errors in the message logs. I don't believe we're using AHCI but its a good point and I will check.

    Long pauses in getblk

    Anyone heard of this? FreeBSD 8.1 system with 24GB and a 3ware raid card is under a heavy disk I/O load. ~300MB/s written to a large array. Pretty regularly, disk I/O drops to zero and nearly every running process is hanging in getblk. Whatever this condition is, it can last up to 10 seconds.

    OpenIPMI Python sample.py causes core

    Its a Bug There is apparently a bug in openipmi 2.0.18 that causes python to core. The answer is to upgrade to openipmi 2.0.19. It appears that the openipmi port in FreeBSD 9 is version 2.0.19.

    OpenIPMI Python sample.py causes core

    Has anyone out there gotten the python interface to OpenIPMI to work on a FreeBSD 8 system? The sample.py script gets a core drop in ipmi_mem_alloc() on start up. Thanks

    LSI megaCLI vs mfiutil, what's the story?

    It appears that megaCLI in the ports of FreeBSD 8.2 has been downgraded. Does this mean that mfiutil is the preferred CLI for LSI controller going forward? Thanks

    Thanks for the quick response.

    FreeBSD 8.x changes in shm_open

    Did something change in fbsd 8.x shm_open() ? Prior to now, shm_open() created an entry in the file system so code like: shm_open( "/tmp/shmfile" , O_CREAT | O_EXCL| O_RDWR , 0777 ); would create the file "/tmp/shmfile". Under fbsd 8.[0-1], I'm not seeing the entry in the file system. I've...

    Intel S5520UR USB and LSI not working

    Partial Fix It appears that one has to purchase a BIOS 'key' in order to enable the LSI controller. This is a bit confusing at product literature made me think that the RAID 0 would operate without the key. USB disks are still an issue.

    Intel S5520UR USB and LSI not working

    I'm wondering if anyone has had any luck installing FreeBSD 8.0 or 8.1 on an Intel S5520UR motherboard. Specifically, I'm attempting to use the built in LSI RAID controller to no avail. I boot into sysinstall and when I attempt to start the install, the install fails at the bsdlabel step...

    FreeBSD 8.0 vs Intel PRO/10GbE SR Server Adapter

    Found the problem. Our motherboard is an Intel 5000PSL. Apparently, there is a setting in the BIOS called "Simulated MSI Support". If this setting is enabled, then driver interrupt processing gets messed up. So the answer is to set "Simulated MSI Support" to DISABLE.

    FreeBSD 8.0 vs Intel PRO/10GbE SR Server Adapter

    The configuration is a freebsd 8.0 system and a linux system with their 10G interfaces connected head to head. There are no firewalls enabled. I can ping the ix0 interface from the fbsd 8.0 system but not the IP on the linux system. Using tcpdump, the linux box shows the ARP request coming...

    FreeBSD 8.0 vs Intel PRO/10GbE SR Server Adapter

    I'm having an odd problem and am wondering if anyone has heard of this. I can bring up the ix0 device via the usual ifconfig commands. I can transmit on ix0 (verified on another host using tcpdump) but not receive. Not receive means tcpdump on ix0 sees no traffic and ping fails though the...
