Subject: Re: setting DISPLAY variable
Date: Wed, 10 Mar 1999 00:03:05 GMT
try a 'route -n' and that gives you your (local) ip-address.
from your server (assuming unix), type: (woithout the quotes)
'setenv DISPLAY=your.local.ip.address:0'
(or may a different syntax: (WITH the qutoes)
DISPLAY='your.local.ip.address:0'
you might also have to give permission for your campus host to connect
to you local machine. From youre local machine try:
xhost your.campus.address (eg/ net.perdue.edu or someting)
if that doesnt work, then i dunno

ps: i think newsgroup people might prefer it if you didnt cross-post.

The default max nr of tasks is 512, but you can set it up to 4092 or
4090 with APM configured (stated in include/linux/tasks.h, this is where
you can set it also). I would think select() would give a lot better
performance. Since the normal max fds per task is 256 maybe split it
over two tasks. Just wondering if you're aware that linux threads are
always separate tasks.

Subject: Write permisions on Directories created through Samba
Date: Tue, 9 Mar 1999 14:58:09 -0500
I've setup Samba on my Linux machine and have shared drives. When I create
files on the Linux machine via a Windows95 workstation, the permission
are -rwxrwxrwx (this is what I specified in the smb.conf file by using
'create mode = 0777'). However when I create a directory on the Linux
machine, it's permissions are -rwxr-xr-x How can I get set write
permisssions also, by default, so that other users can save information in
the new directory?
Thanks for the advice,

Subject: DHCP Core Dumps!
Date: Tue, 09 Mar 1999 19:19:06 -0500
Reply-To: [EMAIL PROTECTED]
I just got ASDL and installed RedHat 5.2 with ethernet support. The
kernel has no problem locating the NIC at the correct I/O and IRQ
value. However, DHCP fails at boot. When I run the daemon from the
command line (/sbin/dhcpcd), I get a core dump. The NIC is a 3COM
EtherLink III 3c509B-TPO 10BaseT. I am currently using the 3c50x driver
pre-compiled in the kernel. I have no problem running the system out of
NT and 98 and all the green lights are on telling me there is a
connection when I try from Linux. Since I am getting a core dump, I
think I might have an installation problem. The installed version is
dhcpcd-0.70-2. Kernel is 2.0.36-0.7.
Any help would be appreciated.

I've got troubles with win98 to access non-public directories. With the
debug level 10 I see no passwd sent. In the opposite, I can access any
directory with Linux (on win server or Linux server). Does anybody see any
way to fix this ? Is it a problem with the win95 bug fix or a problem with
windows 98 ?

Re-check your settings in Kppp: Be sure that (1)Auto Configure Hostname
from this IP is UNCHECKED and (2)Assign Default Route to this Gateway is
CHECKED. Usually the latter is the culprit. Hope this helps.

Your Linux machine should easily handle far more then 5k/sec
I had a AMD 486/133 with 12MB set up for masquerading 4 or so other
Linux and Winbloze machines on my local network and I easily got
300-500k/sec to the downline machines, or pretty much limited to the
internet sites I was downloading from with my cable modem. And this
same Linux box was also running Samba, Apache, Sendmail, and various
other things.

(This assumes Red Hat 5.0)...
Edit /etc/sysconfig/network-scripts/chat-ppp1 (or whatever chat file you
use) Insert a line:
'REPORT' 'CONNECT'
Edit /etc/sysconfig/network-scripts/ifup-ppp
Change this line:
connect "/usr/sbin/chat $chatdbg -f $CHATSCRIPT"
to:
connect "/usr/sbin/chat $chatdbg -f $CHATSCRIPT" 2>/dev/console
- to log to the console, or:
connect "/usr/sbin/chat $chatdbg -r /var/log/modem-speed -f $CHATSCRIPT"
- to log to a file /var/log/modem-speed

Subject: Re: How to telnet ....
Date: Tue, 09 Mar 1999 11:54:16 -0800
There's a good reason root isn't allowed to telnet in, folks. And
telnetting in as a normal user and su'ing to root doesn't fix it. When
you're connecting, if anyone anywhere along the pipe from your keyboard
to the receiving machine is running a sniffer, and you either telnet in
as root, or telnet in as a normal user & su to root, bingo- the sniffer
has your root password. It's a whole, _whole_ lot safer to leave telnet
turned off for root access and allow only encrypted, secure
transactions. Install ssh or one of the other secure services, limit
connections to only those machines you know you will be remotely
connecting from, and make it public policy that anyone who has
administrative privilages and su's to root over an open session will be
maimed. This can make your life much, much simpler in the long run,
especially if you have a very open network with many untrusted segments
between dialup service and remote host (as is often the case in
academia). A little better, even, would be to ssh in as a normal user,
and then su to root-- still secure & encrypted, and you have a log of
who went root when, and what happens after that can be laid at the
appropriate door.

Subject: Network Newbie Question
Date: Tue, 09 Mar 1999 18:36:13 -0600
I have a 2 machine home network, one is win '95, the other Linux. Both
have Ethernet cards installed (the win '95 is a NE2000 compat and Linux
is a 3Com 905). RedHat v5.2, kernel 2.0.36 is the software.
I want to just configure TCP/IP for both and have done the following:
Linux Win '95
IP=192.168.15.2 192.168.15.4
Netmask=255.255.255.0 255.255.255.0
gw=192.168.15.254 192.168.15.254
the whole thing is started by scripts and manually by:
route add -net 192.168.15.0 eth0
route add default gw 192.168.15.254
They are connected via a hub, and the LED's are on.
Yet, when I run 'ping 192.168.15.4' from the Linux box, there is no
response (if I ping it's own IP, there is a reply). Same thing from the
win '95 box. I can ping it's IP, but not the Linux box. I've changed
cables, hubs, NIC's, all to no avail! I've read Net3 from cover to
cover, twice, no help. I have a 'host' file on both machines (even a
LMHOSTS on the '95 box). I can run -
route print
and get the following info: (206.133.136.82 is my ISP addr).

Hello,
I've been struggling with getting my laptop (RH5.2) on the network at my
work. I have access to the Internet through the network (no dial-in).
I've been using netcfg to set up gateway, routing and IP info and think it
might be correct, but I'm not sure because I can't get
/etc/rc.d/init.d/network to accept the 'start' command. My RH manual says
to restart the network connection for the new settings to take place. I
think the usage is /network [start, stop, restart, reload, status, probe]
and several of them work for me... (stop, status and probe) Whenever I
type /network start (or restart) I get the output 'SIOCADDRT: Invalid
argument'. I've even tried going to the /etc/rc.d/init.d directory and
typing './network start', but get the same output.
Any ideas??
Thanks,

Hello, well I finally got dhcpcd to work, I needed v1.3 instead of 0.7
:) Anyways, Im trying to setup a IP-masq Linux box to give my LAN
access to the internet. I have both NICs working, the one connected
to the local network works great, and if I specifiy an IP I can get
the second NIC on the net, and the entire system works flawlessly. But
as some know shaw@home (around here anyways) only uses DHCP therefore
if I specify my own IP, it only works for about 2 days before all of a
sudden the internet is no longer accessible. So... my question is WHY,
even when DHCPcd obtains an IP, can I not ping the internet??
This is what I get when I ping shaws gateway:

I have a 2.2 kernel running with ipchains. In older kernels, there was an
option for IP Accounting, and you used ipfwadm to turn it all on.
The 2.2 kernel doesn't seem to have an IP accounting option, nor can I find
any mention of it in ipfwadm. I need to be able to track how much data is
going through the server.
Also, what tools can I use to see a better report on the IP accounting of
the system than looking at the ip_acct file in /proc?
