LRO will merge several receiving packets together by hardware. Later on the outgoing path, TSO will be used to split them intro peaces of max. mss size. Thus, TCP segments will be reformed be these features. TSO alone does not affect routing. Without LRO, TSO is just used for traffic initiated by your router. > In short, should I keep these features on or turn them off in my OpenBSD > firewall? > What is the OpenBSD recommendation? I recommend to keep it turned on. Just turn it off, if you case of errors. When you have issues which you can fix by turning it off, just send us a bug report. bye, Jan

Maybe if some other logitech mouse models are also working with the same tool?! But, one port for one device seams to be to noisy for the ports tree. When someone here has a similar logitech mouse, please send me a dmesg and a message if it's working or not. Thanks! signature.asc Description: PGP signature
FYI: logitech mouse LED color tool
Hi, I implemented a utility to set the LED color of Logitech mouse devices on OpenBSD. Some people might also use this mouse and would like to change the LED color. If you are interested just try it: https://github.com/younix/g403led I just tested it with the "G403 Prodigy Gaming Mouse" model. If it also work for other models, let me know. Any feedback is welcome. bye, Jan

slow network thread
hi, I've a problem with the network speed. If I download the a file with openbsd, it has only a speed round about 250 kBit/s I could start several downloads with the same speed. So that a program like aget has a speed from 600 till 900. I've this effect with all programs like Firefox, wget and curl. On the same machine with Windows or Linux the speed goes up from 600 till 900kBit/s. Does somebody know why this happen? Driver problem? or a simple configuration? thanks, Jan
HowTo gpio with com-port?
Hello, I want to get some signals from a electronic circuit at my serial-port com0. I don't know how to attach the pin's from the serial port with the gpioctl tool. I think it my hardware is not supported, but I don't know exactly.

graphic card support
Hi, I have a problem to select right graphic cards for my OpenBSD systems. At the first machine I want to use 2 screens in dualhead mode. At the second machine I need a graphic card with 3D-acceleration. I have no idea where i could find information which card or chipset support this features. Are there a list of graphic-chips where i could see which chipsets support the DRI/DRM-feature under OpenBSD? Did the support depends in the xorg-driver or at the OpenBSD kernel implementation of DRI? thanks a lot, Jan
shutdown and syncing discs fail
Hello, I think I have this problem since OpenBSD 4.2 release till now 4.4 current. I have a problem with the shutdown process. When I do run several programs firefox and/or gimp for example and make a shutdown than the system hangs on syncing discs... The computer do nothing. There is no disc-activity. I only could press the power switch to power down the machine. In the follow boot process OpenBSD starts checking the disks with fsck. I have the problem even when I restart X with the [ctl]+[Alt]+[backspace] key combination. When I close all running programs before typing halt -p to the xterm, then everything is fine and before the machine turn off, its printing syncing discs...done. I have the problem on all my three OpenBSD machines. All machines do run Current. thanks for any help. Jan
