slow ethernet
I just bought a 100mb switch and have noticed that my alpha is getting
really poor
performance over the network. I have tried other computers and they get
transfer
rates that are acceptable (20mb/s or so). However, whenever I transfer
to or from
my alpha (an LX with a tulip ethernet card with woody installed) I get
about 100kb/s
download and a maximum of 50kb/s upload speed.
I don't exactly know where to start attacking the problem. Here are a
few things
that look suspicious. Whenever I ping anything I get messages like so:
64 bytes from 18.239.0.1: icmp_seq=6 ttl=255 time=4.0 ms
wrong data byte #8 should be 0x8 but was 0x5c
c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 21 22
23 24 25 26 27 28 29 2a 2b
2c 2d 2e 2f 0 0 0 0 0 0 0 0 0 0 0 0
and this shows up in /var/log/syslog

(fyi 18.239.0.1 is my gateway)
I'm also getting messages in the /var/log/syslog like this whenever I
try to transfer files
with samba:

Jan 24 14:18:08 bartender inetd[11870]: /usr/sbin/tcpd: exit status 0xff
Another thing that seems amiss with my syslog is this:
Jan 24 15:38:01 bartender /USR/SBIN/CRON[19419]: (mail) CMD ( [ -x
/usr/sbin/exim ] && /usr/sbin/exim -q >/dev/null 2>&1)
Jan 24 15:38:01 bartender modprobe: modprobe: Can't locate module
net-pf-10
I have outputs from tulip-diag and from mii-diag as well. Basically
I have lots of information but no idea where to start using it. Any
help you might be able to provide or any references you could refer me
to would be most appreciated.
