Hi folks,
I've got a problem that I suspect is easily cured, I just don't know what to
do.
I've installed Linux from the Red Hat CD (5.1) on a fairly generic PC
connected to an ethernet network with a static IP address (my first Linux
install, too).
The install went smoothly (astonishinly smoothly, IMHO) and everything seemed
to be working OK. I could log in, run xwindows, bring up Netscape and surf.
I could ping other machines and they could ping me.
The problem comes, however, after the box has been running for a while.
After about 4 or 5 hours pass, the Linux box can no longer "see" the network.
It can ping itself, but not any other boxes. Netscape can't load pages
(can't even resolve names). It's as if I had unplugged the box from the
network.
If I reboot, the problem goes away and everything is fine for several hours,
then the problem repeats. I've looked all all the logs I can think of and run
netstat and looked at the inetd config files and all sorts of things, but I
can't see anything wrong.
Anyone got any ideas? Is this a good place to ask?
Thanks in advance for any help,
~rob

Here I DISagree.
Plugging both machines in to a hub (or preferably a switch. Netgear makes a nice,
inexpensive 4 port switch that would do the trick here) and then from the hub
(switch) to a single wall port will allow both machines to talk to each other
without tasking the rest of the network. Granted the hub will still broadcast to the
rest of the net, and the switch won't once it finds the other machine (ergo that
suggestion). The other great benifit here would be that your sun and alpha boxes
could communicate with each other at 100Mb/s, while talking to the rest of the LAN
at 10Mb/s.

First of all set up the JetDirect printserver to accept LPD/LPR printing
you can do this by telnetting to the printserver.
Then lounch control-panel in redhat and set up the printserver as an
remote UNIX LPD/LPR host and as hostname and remoteque give the
hostname for the JetDirect printserver.
#Done!

So what's the output of ifconfig and netstat -nr ?
It is naive: to glue pages of output and think they would not
ask for more...

I'm pretty sure that's completely wrong, and that it is a netmask
shorthand having to do with how many of the digits of an IP address must
match the given address, but I haven't quite gotten a handle on it.

Date: Tue, 09 Feb 1999 23:22:40 +0100
I've got a linux server with redhat 5.2 (with kernel 2.0.36)
The 3COM card is a 3c905. It's in 100Mhz mode. (at boot up time is says
so.)
The Hub (100Mhz) also confirms it, and i can connect to the server.
(It's running Samba server 2.0).
However, if i do speed test's it performs like a 10Mhz card, about
800K/Sec.
The workstation also has a 3COM 3c905b, which i set at 100Mhz, full
duplex.
Does anyone know what is wrong? And how (and in what config files) to
change settings for the network interface card?.
Ps, I'm new to Linux... ;)

Thanks...
After some poking around I managed to get it to compile by
manually inserting the line "CONFIG_RTL8139=m" into the
.config file. The option still isn't enabled but at least
the module is included when I compile everything.

Subject: Serial port not working
Date: Tue, 9 Feb 1999 17:11:59 -0600
I've recently upgraded my box from a Cyrix P200+ to a Dell P2 400. I've
transfered my Byterunner ISA 16650 high speed serial port to the box. The
box also has a USR 56k X2 modem (non-winmodem).
The problem I'm having is that I can't get either the internal serial port
or the Byterunner card to work with my ISDN terminal adapter (Adtran
Express XRT). I get constant dropped packet errors when using the TA.
I'm using kernel 2.0.34 currently with a patch from Rob Riggs to identify
my Byterunner card. The kernel idents the high-speed serial port on
bootup just fine but still can't get ISDN TA to work without dropped
packets. Setserial is set to uart 16750, spd_vhi via another patch to
setserial from Rob's website (http://www.devilsthumb.com/~rob).
Any help would be greatly appreciated

Subject: 2.0.34->2.2.1: transmit timed out w/3c574?
Date: 9 Feb 1999 17:51:18 -0500
I recently upgraded from kernel 2.0.34 to 2.2.1. Now, whenever I try
to upload a file of any size (>30K or so) to any other machine on my
network using ftp, I see the following console message every 10
seconds or so:
eth0: Transmit timed out, Tx_status 00 status 2000 Tx FIFO room 4092.
and the transmission speed drops to nearly zero. If I try to ping the
machine I'm uploading to while this is going on, it'll sit there for
10 seconds and then print out 10 packets all at once, with return
times 9000 ms, 8000 ms, ... , 0 ms, then repeat. If I stop the upload
and wait a minute or so, ping times and network throughput go back up
to normal.
This machine is a Dell Inspiron 3200. The Ethernet card is a 3com
3c574 10/100. Things are just fine under kernel 2.0.34 and
pcmcia-cs-3.0.0; they break (as described above) under 2.2.1 and
pcmcia-cs-3.0.8.
Anyone have an idea as to what would cause this? I'm not doing
anything mysterious with my network configuration (just an ifconfig
eth0, then 'route add -net ...' if running 2.0.34, then 'route add
default gw'), and I've tried swapping cables, PC card slots, and the
like.
Frustrated,

I've frequenly had problems with uploading from an earthlink site to an
earthlink site. This includes but is not limited to dial up accounts. For
example, I could not post to usenet newsgroups if the article was long.
Uploading via ftp was also a disaster. Even telneting from one earthlink
dialup to another caused problems. I believe this to be a problem with
earthlink (UUNET) having trouble routing internal packets and eventually
dropping them.
But my situation may be different. For example, I did not get broken
connections (FIN_WAIT1). Instead, packets would accumulate in the Sendq
because the sending end would get no acknowledgement that the packets have
been sent.
I have since switched to another provider as my primary ISP and only use
earthlink as a "backup".
BTW, Linux doesnt use it's own FTP protocol. It uses the same widely known
protocol that all other OS's use.
