...ransfer larger files > 300 bytes. What ended up fixing the issue is tweaking the /dev/tcp module, and disabling selective acknowledgment (SACK). I ran the following command, and rsync worked fine with no special parameters between both hosts, using different transport mechanisms. -- bash-2.03# ndd -get /dev/tcp tcp_sack_permitted 2 bash-2.03# ndd -set /dev/tcp tcp_sack_permitted 0 bash-2.03# ndd -get /dev/tcp tcp_sack_permitted 0 -- After reading the man page (below) I set the parameter to 1, so that Solaris would accept connections using SACK, but not initiate connections using it. - This...

Hi, I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow? Also, can crossbow do things like steer outgoing packets to the

I am sharing out ZFS ISCSI luns to my Mac. When copying large files, the network will hang in the middle of the transfer and the LUN will become unavailable until I plumb the NIC. This issue appears to only occur only when I am reading files (ie..syncing an ipod) and not writing (I''m not 100% sure though). When I snoop the interface I notice a bunch of ARP lookups. Any ideas? Thanks in

G'day. I am trying to get a very old Solaris 5.7 server to ftp data to my updated CentOS 5.4 server but the Solaris box keeps losing networking after sending some data. I can't ping the Solaris box from any of the servers on my network. Could this be related to a much newer (modern) TCP/IP stack in Linux and TCP options? If so, does anyone have any suggestions for how I can tune the

I'm in the process of rolling out new setups with dovecot on CentOS 5.2 and I notice that dovecot doesn't handle the brute-force attacks too nice. I reduced the limit a bit to some reasonable looking value: login_max_processes_count = 32 to stop them earlier and the number of processes stops at that figure when an attack happens. However, it stays at this count for hours although the

The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just
