I would say determine if your load is cpu/IO based.
If it is IO, is it Disk or Network?
If Disk, SCSI? RAID? these would be likely options.
If Network, multiple NICs?
I do agree that you would need to do some calculations to determine
where, specifically, your laod is, and how much it is.

Subject: NFS Trouble
Date: Wed, 06 Jan 1999 15:46:34 -0700
I am having problems exporting directories on my Linux box. I am
running RedHat 5.2 (2.0.36)
I've read through the man pages (several times) and I am not having any
luck. The problem is not exporting the file systems, but mapping the
UID/GID. I can't seem to over ride the default all_squash property
which maps all UID's to nobody. I am using entries in my export file
that look like this:
/path (rw,no_root_squash)
/path2 host(rw,no_root_squash)
Neither work in regards to UID mapping. I have RW access, but as nobody
that is pretty useless.
By the way, Yes I am restarting mountd and nfsd.
Any ideas?

Subject: leased line pppd problem
Date: Wed, 6 Jan 1999 01:15:56 +0100
I use a Slackware 3.5 linux and a Goramo BPh modem over an asynchronous
leased line.
After running everything I fail to ping the remote end of ppp link.
#ppp init:
>/usr/sbin/pppd-2.5 /dev/cua0 38400 my_ip:remote_ip
#/etc/ppp/options follows:
modem
crtscts
defaultroute
-chap
-pap
persist
passive
debug
netmask 255.255.255.192
mtu 552
mru 552
asyncmap 0
I am wondering why pppd run with 'defaultroute' option doesn't make any
changes to routing table nor to ifconfig.
Actually, i have to enter manually:
>/sbin/ifconfig ppp0 mtu 552 pointopoint remote_ip my_ip netmask
255.255.255.192 up
Now things look a whole lot better:
>ifconfig
ppp0 Link encap:Point-to-Point Protocol
inet addr:my_ip P-t-P:remote_ip Mask:255.255.255.192
UP POINTOPOINT RUNNING MTU:552 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:10 errors:0 dropped:0 overruns:0 carrier:0
Still need to set up routing:
>/sbin/route add -host remote_ip ppp0
# shouldn't above be started automagically by pppd?
>/sbin/route add default gw remote_ip ppp0
Command >route issued at this point without any further options hangs up
(blank screen). Pressing ctrl+z makes it return to shell.
Let's try to ping the remote server. Results?
Lights on my modem blink, >pppstat shows properly outgoing packets, but..
nothing comes back :(
The same concerns any other computer on the net.
Why?
Everything works just fine under Windows 95, so apparently ppp server is not
an issue here.
The serial port settings are ok either.
Any help would be greatly appreciated, any suggestions welcome.

Subject: keeping two ppp connection alive?
Date: Thu, 07 Jan 1999 12:08:14 -0500
Reply-To: [EMAIL PROTECTED]
Hello:
Here's the problem:
I have two ppp connections to my ISP, I am using eql to keep
them "tied together" and sometimes I lose one connection. I want to
write a script that keeps them alive without using diald because I think
diald screws up eql.....So, I thought I'd ask someone out there for a
good book on shell script programming because I'm a newbe......
Here's what I envision my script doing:
1) looking to see if there are two ppp connections alive
2) checking to see if eql is working
3) deleting the ppp connections from the routing table (requisite for
eql to work properly)
4) adding eql as the default route
5) making the mtu of all connections the same
I think this could be done best with two scripts...One in the crontab
which would constantly look for two ppp connections and another that
gets called by the crontab script to initiate the ppp connections
again......
Here's what I thought of so far...Syntax may be screwed up because this
is my first script:
#!/bin/sh
$ppp0 #I think these are variables in a shell script
#can't remember?
$ppp1
$Local_IP
if[` ifconfig | grep P-t-P | awk '{print$3}' | awk -F :
'{print $2}' | cat -b | wc -l ` -eq 2];
then
$ppp0 = /ifconfig/ | grep P-t-P | awk '{print$3}' | awk
-F : '{print $2}'
$ppp1 = same_as_above_except_last line.... awk
'{print$4}'
ifup $ppp0
ifup $ppp1
fi
this will hopefully look for two ppp connections and get them going if
they are down.....I see one probelm here though...What happens if one is
up? It still tries to start them both...Is that O.K? Thanks in
advance.....If I think of more I'll post it so someone can
correct/advise as I go.....Thanks again!
Sincerely,
Brian Gilman

Subject: TTY Settings When Telnetting
Date: Thu, 7 Jan 1999 11:07:53 -0600
I have a RH Linux box with kernel 2.0.34 on a LAN offsite. I have two
different locations each one has a 128K ISDN to the offsite LAN/Linux box.
Let's call the Linux box "linux1" and that domain "local.com". Site one will
be "home.com" and site two will be "work.com". From home.com I can telnet
across the ISDN to the Linux box and it connects and everything works 100%.
>From work.com I can telnet across the ISDN to the Linux box and almost
everything works fine. The biggest hassle is full screen editors like JOE,
PINE, TIN, etc. From home.com I can scroll in all four directions and the
screen follows accordingly. At work.com I can scroll all directions except
up. When I move up it visually moves a few lines at the top of the window
and logically moves everything correctly. Which means I can look at line,
let's say, 12 and it may say one thing but moving down to that line and
moving horizontally reveals the logically placed text instead of the
visually placed text.
It's hard to explain, but this always happens after a new install and
usually goes away after a few days. This has occurred since I started using
Linux in the 1.x days.
I telnet to the Linux box with the same account (i.e. same .bashrc) and a
"set" command from work.com and home.com are identical. The telnet client is
the same program on the same platform with the same settings at both sites.
The one possible factor that plays into this is that the computers at
home.com are actually all given a local.com domain name. The only effect I
think this could have is that the Linux box thinks telnet connections from
home.com are "local" and is changing something in the TTY settings. A "who"
shows that ttyp0 is the pseudo TTY number given to both sessions and NOT a
tty1.
Any assistance appreciated. Please CC to Usenet and email as my Usenet feed
from MCI/C&W is very unreliable.
Thank you.

Hi!
I just begin to use samba, I setup samba using linuxconf, and I get to the
point where I can see the samba server icon in Windows' Network
Neighborhood. However, when I try to open the icon (with double-click it
or from Start->Run), I got a dialog box asking password (from Win95), or
login name & password (from NT).
If I enter a login name which exist in the linux machine (whether it uniq
to the linux machine or not), Windows give this error:
\\<server-name> is not accessible
The credentials supplied conflict with an existing set of credentials.
If I enter a login name uniq for the NT Domain, the samba server just
won't accept the password, wether it is true or not.
Any help will be appreciated.
Some info:
Linux Redhat 5.1: 2.0.34 #1 Fri May 8 16:05:57 EDT 1998 i586 unknown

Subject: Dial-up problems with RH Linux 5.1
Date: Thu, 7 Jan 1999 18:20:58 +0000
I have just recently installed Linux 5.1 and have being trying to dial-up to my
university connection using ppp with the possibility of using the internet.
So far I have just managed it to dial the university, but then shortly after
dialing through the modem hangs up.
My first question is have I first of all set up the networking info correctly
in the right place (linuxconf, control panel etc...) or do I need to
install TCP/IP explicitly - as in Win95 I had problems then realised I did
not have TCP/IP installed, or how do you tell if TCP/IP is already
installed and running.
The university have given me a fixed IP address with name and three DNS
servers, gateway, subnet mask, dial-in usercode (same as for my host name)
and even a script.
I feel that I must be missing something fairly simple and would be most
grateful for any replies/postings or references that you can offer.
Cheers Bruce

So this is what's happening so far: Your modem gets initialized, it dials
your ISP and gets connected. Then your script sends one enter, <username>
and <password^M>. Then it starts waiting for the ppp to come up. Which
doesn't happen. What you should do is to dial your ISP manually (minicom
etc..) and check what you really should expect / send, and modify your
script with that information. Too bad you're using Red Hat - it's dialing
scripts are REALLY messy and hard to figure out. You probably would get it
done easier by writing everything from scratch..

Date: 07 Jan 1999 10:36:32 -0800
Greets,
I have an Acer Extensa 366D laptop that I'd like to hook up to a cable
modem. I currently have a D-link PCMCIA DE-660 Ethernet card, but I cannot
seem to get things to work. I tried with both the RedHat 5.1 kernel and
pcmcia-3.0.0 package, as well as kernel 2.0.36, without success. Upon
booting or inserting the card, it is detected and identified as the D-Link
DE-660 Ethernet Card. Modules pcmcia/pcnet_cs.o and net/8390.o are
inserted. /var/log/messages shows: eth0: NE2000 Compatible: port 0x300, irq
5, hw_addr 00:80:c8:8B:DF:96
ifconfig lists eth0 with the correct addresses. The problem is that no
traffic seems to come in or out... a ping to an ip address doesn't find an
machine, and trying to ping my computer from the net fails as well. I've
set the addresses and such in netcfg, looked at the docs for pcmcia
package, fiddled, etc, all without any luck. If someone could provide some
pointers, symptoms to look for, or anything, I'd apprecite it. Thanks,

This is 'cut' from news.htm , in the Netscape 4.5 package:-

To work offline:
* From the File menu, choose Offline, then Work Offline. To go back

Which is false since (Linux version 4.5) has no "Offline" selection for
the "File" menu of Mesenger (Mail & newsgroups).
I've wasted a lot of time with this 'damned thing' !
Has anybody managed to use Netscape 4.5 for newgroups to :-
* read the new headers,
* OFFLINE mark headers for which you want the bodies, next time online,
* delete other headers,
* download 'flagged' bodies,
* delete bodies randomly.
