I apologize for the length of this message,
I have seen this problem several times on Linux 2.2 hosts and routers...

It looks like the first 3 packets are recieved, but the ping program doesn't see them
until 3 packets are in the queue, then it
looks like they took 3000 ms to return. I did a background tcpdump and pinged and saw

I had done several other ping tests and the response time rose to
about 5000ms. When I tcpdump from another host on the lan, it shows
the response immediately after the request (about 0.1ms on 100BaseT).
I am using a NetGear FA310TX with a real Dec Tulip chip on one link
and also the same NIC with the Lite-ON PNIC chip on another link and
both links experience the same problem. I am using kernel 2.2.5 with
iproute2. If I set both interfaces to down 'ip link set eth0 down'
and bring them back up and give them addresses again, the problem goes
away. I can reproduce this problem be running the NetPIPE test, found at:
http://www.scl.ameslab.gov/Projects/ClusterCookbook/nprun.html
I have run this test several times successfully on 2.2.4, but I had the
same problem occur under other circumstances.
Is this a kernel bug? Has anyone else had this problem? Does anyone know
what causes it?

Subject: samba cant see win98 shares
Date: Fri, 23 Apr 1999 13:44:14 -0700
new to linux
I have a small network of 1 linux redhat 5.2 kernel 2.0.36 running samba
1.9.18p10 and 1 win98 computer.
I recently changed my network security from share level to user level, and I
can't see my windows shares on the network anymore. I can see and access my
redhat shares from windows network neighborhood. Some of the symtoms which
seem to provide clues to the origin of the problem include the following:
When trying to set up the windows printer as a shared network printer I
recieve this message " you cannot view the list of users at this time.
Please try again later."
from windows DOS prompt running net view \\windowsHostname I get:
C:\>net view \\192.168.1.1
Error 1311: There are currently no logon servers available to service the
logon request.
in linux running smbclient -L windowshostname I get:
smbclient -L windowshostname
Added interface ip=192.168.1.254 bcast=192.168.1.255 nmask=255.255.255.0
SMBnegprot failed. myname=LINU destname=CERI - ERRSRV - 1311
and running testparm smb.conf I noticed 2 peculiar settings that might be a
problem, but I dont know how to change them.
protocol = NT1
announce as = NT
I see in Sery's book "Linux Network Toolkit" these are set as:
protocol: 8
announce as: 1
Can anyone identify the problem or point me to where to look for a solution?
TIA

rinetd is very similar to redir. They're both very usable. They are a
little slower than ipportfw. The main problem I have with them is they
will show all accesses as from the firewall machine's internal IP
address in all logs on the internal server. If you don't care about
the logs then there isn't much of a reason to use ipportfw.

Date: Sun, 18 Apr 1999 09:36:19 GMT
fetchmail can be configured to do a credible job of this. I saw
instructions for doing this in the IDG book "The Liunux Network" (ISBN
1-55828-589-X). Here's a really brief summary.
1 - you must have your own domain name.
2 - You must arrange with your ISP that all e-mail to your domain is
directed into one psuedouser account.
3 - .fetchmailrc must be edited
poll myisp.com
protocol POP3
localdomains mydomain.org
no dns
no envelope
user pseudouser with password pseudouserpassword to
fred
peter
here
make a script that invokes fetchmail (e.g. --
fetchmail -f /usr/local/etc/.fetchmailrc -syslog )
configure syslog to handle error reporting how you want
run the script with cron as often as you see fit.

of the machines, but when I do a talk request from my prompt to the other

Subject: How to get SNMP information from my Linux box
Date: Fri, 23 Apr 1999 23:07:06 -0400
I use MRTG running on my Linux box to pull stats from a couple switches and
a Sun box. When I tried to pull from my Linux box, I think I got a
connection rejected.
I have not configured anything on my box in the way of server side SNMP
stuff (i.e. community names, who can/can't pull from it, etc). This is a
Debian 2.x install, so maybe some of this is pre-configured.
First, is SNMP reporting a function of the kernel or a separate daemon.
Second, is there a good resource on this. I did not see a How-To on it.
Thanks,
Mike

No, because the networking code will automatically match the packet as a
200.200.200.0 packet through the first routing entry, then shove it off to
eth1

this means that some or all hosts will be unreachable.
perhaps ther is a problem with your name server?
if you site must use a non-root name server, you will need to set the

may (or may not ) be nesessary to set this variable, or the socks host
preference, to the ip address of the host in question rather than its name.

The folklore about not using all-zeroes and all-ones has gotten blown
further and further out of proportion. The actual situation is that you
should
not use HOST number 0 or all-ones on any subnet, since all-ones is the
broadcast address, and some brain-dead software from the distant past
uses all-zeroes as the broadcast address. But this does not, so far as I
know
extend into the network number part. Especially in the case you cited, you
are in the Class C network space, and so 192.168.0.x and 192.168.1.x
are actually different networks, not just different subnets.
So, to make a long flame short, feel free to use 192.168.0.x, but avoid
the host addresses 192.168.0.0 and 192.168.0.255

Hi!
I'm running Red hat v5.2 and I have a problem with my host name.
Before I dial-up to my ISP provider (with 'ifup ppp0') I have my host
name as it should (localhost).
But as soon as I connect to my ISP-provider I get something else
(t0985645). And the new host name stays even after I've logged off.
What I want and what I think is supposed to be is that my host name
remain the same when I log in, and after I've disconnected, to my
ISP-provider.
How do I fix this? What am I doing wrong?
Thanks,

I found more stuff.
ImageStream sell an all-in-one-box solutions (running Linux):
http://www.imagestream-is.com/
They also resell (and use) the synchronous cards from SDL Communications:
http://www.sdlcomm.com/
The RISCom/N2s is what you're after.
The pricing at ImageStream for this card is $655. ImageStream indicates
Linux support. I didn't surf the SDL Communications site for price or
support.
The price seems high to me... let me know if you find cheaper stuff.
