Hi guys,
I run a P200MMX with 64Mb RAM, a USR Sportster 33.6k modem and the 2.2.6-STABLE. I've some problems here and I need help.
1) I compiled my kernel with the following options: PPP_DEFLATE, PPP_BSDCOMP, PPP_FILTER. I'm using minicom to dial to my ISP and pppd v2.2.0. I made a options file in the /etc/ppp dir and I used the deflate 12,12 option in this file. The problem is that pppd is not understanding this deflate option... so I'm not using any kind of compression... any help?
2) Most of the times, I connect at 33.600 with my ISP. My ISP has a 1Mbits link and it is fast. The problem is that my 2.2.6 seems to be very slow when I'm doing more than one thing at a time. For example, if I'm doing an ftp in one console and in another one I try to use fetchmail, lynx or try to make a telnet session, it takes an year to connect or even it doesn't connect... I compiled my kernel with maxusers 64 and I didn't change nothing more. I sometimes use Linux on the same computer and this problem doesn't show up, so it's not a hardware problem. I'm using 6 virtual-consoles here. Maybe it's some configuration missing to tune up my FreeBSD... that's all that I want... Use the Internet in all consoles in a real multitasking enviroment without having to wait forever for an application to finish so I can start a new one..:)))))
I don't think you're really seeing a problem that can be fixed. I see this with Linux, too, for what it it's worth. The problem is that the 33.6Kbps is just a nasty slow tunnel, through which your sports car is trying to speed. Compared to a P200, that modem is almost standing still.
Some programs seem to be worse bwith hogs than others. FTP seems to be the worst offender; start an ftp session, and nothing else ever seems (i.e. it takes two minutes ;) to get a packet through.
I hope a kernel dude will step forward. It just seems like there's no sharing going on with the ppp channel.
