There are some dynamic configuration parameters so issue this at prompt
echo 4096 > /proc/sys/kernel/file-max
echo 10000 > /proc/sys/kernel/inode-max
there are more but this will get rid off your problem.
you must put this in your rc initialization script, so the next
time you boot your system this parameters will be set.
Maybe /etc/rc.d/rc.local

Subject: FTP problems
Date: Fri, 17 Sep 1999 03:00:04 GMT
Hello
I have installed Red Hat Linux 6.0 to a 486 / 66 and am having trouble with
FTP access from my other machines. Other machines are Windows NT 4
Workstation and Windows 95. Network is Thin Ethernet.
I can Ping and Telnet to the Linux machine from the Windows machines
without problems, but when I try to FTP I get a message stating "Connected
to 172.16.1.5" and then the message "Connection closed by remote host."
I have tried to FTP from the Linux machine to itself, but I get the message
"Connected to localhost" and then the message "421 Service not available,
remote server has closed connection".
I have checked the /etc/inetd.conf file which has the default entries (from
install) for Telnet and FTP. I have also checked the /etc/hosts.allow and
the /etc/hosts.deny files which were empty (apart from a few remmed out
comments).
I am fairly adept with Windows and general networking, but I am a relative
newbie when it comes to Linux.
Can anyone help?
Thanks
David

Subject: SMC 1211TX and @home
Date: Fri, 17 Sep 1999 04:16:26 GMT
ok, here goes...
i have a dual-boot win95/red hat 6.0 system. i just got hooked-up with
@home and they installed an SMC1211TX 10/100 ethernet card on my win95
side and it worked fine. i then booted to my linux side and installed
red hat 6.0 over ftp with the newly created ethenet/@home connection and
it installed the eth driver correctly and now runs like a charm.
the problem arises when i boot back to win95. the connection is shaky at
best and i constantly get the following error:
"System has detected a conflict for IP #.#.#.# with system having
hardware address 00:E0:29:25:68:D8. This interface has been disabled."
the IP address in the error message is my static IP but the hardware
address is not mine. does this mean the someone else has also configured
their card with my IP address?
i have rebooted my win95 system about a million times and if it wasn't
for games i would never use the damn sorry excuse for an os. ok i've
ranted long enough.
please obi wan your my only hope!!!!!!!!!!!!!!!!

Just create the appropriate options.ttySX files. Pppd knows what serial
port it is connected to and will read the correct one.

Greetings!,
Thinkin back aways....There the answer is ...right before your eyes,
looks like the packets are going out, but not back, if so, then the
problem is your net mask is not set correctly. All machines on the same
subnet, must have their netmask set the same, and if there is a gateway
out of the subnet, the gateway will have to be specified too.
Now if you must change the driver, but why, L-M is running the driver
version 1.1 from Donald Becker. That was the latest stable release. I
HAD a 3Com EtherLink XL PCI 3c900-combo, but ditched it for favor of my
WD8013. I was having problems with the transmission rate versus the
reception rate. Receiving was great, transmission about half speed.
Don't have time at the moment to troubleshoot.
BTW, the WD8013 might be old, but she sure is a goodie, 988K/second!
cat /etc/conf.modules
Show see a line like
alias eth0 3c509
alias 3c509 options etc,etc (here you would insert the correct options
to override factory default settings.
Remember, though, even if you remove the above to lines, and the card is
set at factory default settings, or at least the settings auto-pobing
will use, and the card is in the machine when booting up, it will still
define the card!
Take a look at this url: http://www.dogpile.com search for 3c509
and also defintely here!
http://cesdis.gsfc.nasa.gov/linux/drivers/index.html - lot of great
stuff here!

Date: Fri, 17 Sep 1999 04:29:20 GMT
Hi, I am on a college campus that has each dorm on a switched hub. As
a consequence (or maybe not) students in different dorms cannot see
each other. I really don't need to see any of my friends computers,
but I would like to share my files with them. Is there any way to
configure samba to allow the other dorms to see my computer?? Or to
atleast map my shares?? Note: Mapping drives does not work, and my
friends use Windows so they can't use the nifty -I option with
smbclient.... Please reply to [EMAIL PROTECTED] as well as the
newsgroup.
Thanks in advance,

Subject: Re: VPN with DSL and NAT router???
I'm setting up two firewalls for a customer and the SDSL provider gives
them 1 usable, truly routed, IP# (/30 block) to use on their firewall.
I have it doing masq'ing, inbound portfw for their internal webserver
and email server, and installed the PPTPD on the machine. I'm finishing
the testing of it before completing the install next week but I can use
Win95 with DUN1.2 or higher, or Win98 or NT4.0 clients and do PPTP
directly to the Linux box and gain access to the inside of my test
network at the office. I'm starting to use the PPTP with CHAP required
for VPN's for other clients after this. Free and cheap VPN
(basically.) For what they're using it for (TN3270 to an AS/400 inside
their network and connection to exchange server) it looks like it'll do
the job.

Hi Ajesh,
Depending on how the network is segmented, what you can do between these
machines may be limited. See if your friend is able to telnet to port
139 on your machine (make sure samba is running on your machine at the
time). If that works, see if he can map a share on your machine
specifying your ip address -- \\a.b.c.d\sharedArea. NT may be more
cooperative in this effort than 95 or 98.

Subject: DSL and routing & gateway & IPs & windoze
Date: Thu, 16 Sep 1999 22:07:00 -0700
Well.. I got the faster connection, I got ADSL with an Alcatel "modem"..
I have a LAN with Linux (SuSE) & 'doze (98). I have more than one IP
from my ISP & I want to use Linux as the firewall/router/gateway.
However, I can only find stuff on masquerading and -mantions- of how
routing it built into the kernel. But I am having a hard time finding
information on how to set up my -simple- situation, not a HUGE network
with several subnets & routers & other stuff.
I have 2 NICs in Linux, one is going to the ADSL "modem" & the other is
to the LAN. 'doze has one NIC. If I have the IPs from my ISP in place
on the LAN, I lose Internet altogether, but the LAN talks to itself
fine. If I put local network IPs in on the LAN side (ie 192.168.0.x), I
get Internet on Linux. Either way, I can't access the DSL connection
from 'doze no matter what I try.
I have been trying to find FAQs ot How-To's or anything, but all I keep
running into is masquerading. I don't need or want to masq. I have
more IPs than I have devices or even interfaces. I want something that
can help me set up a -small- network to allow both computers (or 3 or 4)
to connect via the same Internet connection but without free access to
everything on them.
I am not entirely sure where my problem lies, in IPs, in routing, in the
firewall, in a gateway (or lack thereof from the LAN side), or something
I am overlooking entirely. As I said, I do not want to use masquing,
even if it is easier.
In advance, thanks for helping.... I am not a total novice, but this is
starting to make me feel like an idiot.

Hello,
Looks like in this situation you may need two blocks of IP addresses instead
of one. Then you can use your Linux box as a router/firewall.
I also heard of 'drop in' firewall configuration (all firewall interfaces
get assigned the same IP address and network address translation is used
with MAC addresses).
I'm not sure if it's possible to configure Linux box to perform in the same
capacity.
Good luck!

They can be on different IP addresses. Remember tht names are irrelevant
to the internet. It operates completely on IP addresses. You just have
to make sure that the DNS name server advertises the different addresses
properly. Whether there is some difficulty in this I do not know.
