RE: wi0 and mtu setting
I believe I read somewhere that 802.11b standard supports larger MTUs than 1500. I know basic ethernet MTU is 1500 but even my crappy old Nortel 8603 routing switch supports up to MTU 1960 Any corrections appreciated // Sten -Original Message- From: David Magda [mailto:[EMAIL PROTECTED]] Sent: 2. januar 2003 21:59 To: Evren Yurtesen Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: wi0 and mtu setting Evren Yurtesen [EMAIL PROTECTED] writes: I wonder how come wi driver doesnt let me to set mtu higher than 1500 even though I know the card supports it?

vnconfig and /dev/vn devices?
I've been messing around with the honeynet forensic challenges, and have finally managed to mount my first image after recompiling with EXT2FS and vn in my kernel configuration. However, right now I just have the one /dev/vn0. Is there any way to get other vn devices such as vn0 vn1 etc so that I can mount multiple filesystems at a time?

Re: wi0 and mtu setting
But if you are using PPPoE then you should set the mtu of the pppoe connections to 1492 because of the 8 bytes overhead of the PPPoE (if you are not using encryption or compression) So if a server sends a packets which are 1500bytes and plus 8bytes PPPoE then it is 1508 bytes. So the sending interface should be able to set the ethernet MTU to 1508 which is possible to use at least in prism cards until 1600 bytes (I didnt test this in orinoco/lucent) not with freebsd of course with mikrotik routeros I think this option should be provided to user even though it breaks the standarts to be used at own risk to set MTU higher than 1500. Maybe it is not physically possible to set MTU higher than 1500 in normal ethernet but this limitation obviously doesnt apply to wireless interfaces and gigabit ethernet cards.

RE: wi0 and mtu setting
It could be really helpful if you could find that standard papers :) I couldnt find anything from google. But I know normally ethernet interfaces just are not capable of sending packets larger than 1500 physically but only gigabit and wireless ethernets support this for some reason. Perhaps there should be a standart for this otherwise the producers wouldnt go into the trouble to support this huh? =) On Thu, 2 Jan 2003, Sten Daniel Sørsdal wrote: I believe I read somewhere that 802.11b standard supports larger MTUs than 1500.

Re: wi0 and mtu setting
I definetely agree and obviously since mikrotikos supports this then linux should do since mikrotikos is built on linux.

I was trying to install 4.7-RELEASE, but it detected only controller - not RAID1 mirror. And of course it complains there are no disks in machine. DOS can see that array. Array is supported by controller BIOS - not any external win drivers/utility. The RAIDframe project in FreeBSD 5.0 was intended to support Adaptec HostRAID. Unfortunately, priorities have changed and that effort has stalled indefinitely. You are welcome to contact Adaptec through official channels and voice your concern. Just to make Adaptec aware there is such demand from users? Yes. Please. I can understand now I can only make software RAID emulation. True, the 'secret sauce' of HostRAID is that the BIOS understands RAID 0, 1, and 10, so you can boot off of it. For those that only need software RAID and those that keep their boot drive separate from their main arrays, this is a cool feature.

RE: FreeBSD Stability
That is impressive. I'm curious if they stayed at a particular version or if they update as new versions are available? I thought I read somewhere that FreeBSD could load a new kernel without rebooting? I am interested in this, and I must admit that I dont really know that much about the kernel, but if anyone knows of a nice way to do this, PLEASE Let me know. This would be a great for those occational updates to freebsd-stable. I would get to keep my uptime. However, I dont think that this is possible. -Scott On Thu, 2 Jan 2003, Marcus Reid wrote: I like to point people in the direction of: http://uptime.netcraft.com/up/today/top.avg.html Thanks, I forgot where this site was.
