As of linux 2.0.36, the realtek 8139 is supported. For client machine no
problem. On a heavily loaded server would use something else - 3Com or
Intel.

Subject: NIS problem
We want to use a NIS server to share passwd files over a small network,
but we
have problems with ypserv (V. 1.3.6. tcp-wrapper):
The server starts up well, but crashes with a segmentation fault
whenever somebody requests the "passwd.byuid" map by trying to log into
a client.
Any suggestions?

Your chat script expects ogin: and doesn't get it. Many ISPs no

can cause the connection to fail in that case.

The problem is probably in /etc/hosts.deny. Either your host is explicitly
denied access to telnet, or all hosts are denied access to telnet, or
you don't have a reverse DNS mapping.

Inexpensive Alternative:
Round Robin the DNS. Use OSPF (on your router too). Give each of the
two webservers an IP alias of the others host's real address. Assign the
aliased IP's a high cost on both machines as a stub host.
That'll give you some balancing and failover on a budget.

A gender changer only changes the type of connector. It does nothing
for crossing the send and receive lines. This means the two send
lines are trying to send to each other. A nul modem will cross the
send & receive lines and make some other connections for handshaking.

We've got four Macs connected over ethernet, and a 4/600PS that
they all talk to. The printer is connected to the ethernet LAN
with an AsanteTalk converter. The b&w G3 happily ignores not
having serial ports...

Subject: password sync with samba
Date: Fri, 30 Jul 1999 16:22:07 GMT
I have a problem with RedHat 6.0 using samba-2.0.5a to get the password
synchronisation working. The RH server is setup as a primary domain
controller, allowing win95 clients to log on, and browse everything
correctly. If password synchronisation is turned off in the smb.conf,
then the 95 client is able to change its samba password without a
problem, the problem comes when trying to get the UNIX passwords
synchronised automatically.
smb.conf is set to have encrypted passwords, and to use password
synchronisation. The password program is /usr/bin/passwd %u, and the
chat line is the following
passwd chat = Changing*password*for*user*%u\nNew*UNIX*password:* %n\n
\nRetype*new*UNIX*password:* %n\n
passwd:*all*authentification*tokens*updated*succesfully\n
After looking at the debugging information, the smbd interacts correctly
with the password changing program until just after having given it the
password for the second time. Then the error "read_with_timeout: timeout
read. select timed out." is given. There is no reason why it should time
out there, as it should finish changing the password and then display
the last chat line.
If anyone has any remedies for this problem please post them.
Many thanks in advance

Access creates a locking .ldb file in the same directory as the shared
.mdb. You need to make sure this file is getting a permission that makes
it readable by the other users (try to look at the .ldb file with
notepad for instance). You might need a file creation line in the samba
share definition with 777 permissions for new file creation.

Subject: Linux box as gateway for local network
Date: Fri, 30 Jul 1999 17:11:20 GMT
I have three computers of which one (a Linux 2.2 box with ethernet and
ISDN) can connect to the Internet through a dial up connection (dynamic
IP-address). I want to set up my Linux box, so it acts as a gateway for
the other machines, but somehow I'm not succeeding. From box B
(localnet) I am able to ping my dynamic IP, assigned by my ISP, but I
can't ping any other outside IP-addresses. How can I do this? I can't
seem to figure out IP-masquarading (or it simply doesn't work).
ipchains -A forward -d 12.0.0.3/32 -d 0.0.0.0/0
doesn't seem to do the trick (while 12.0.0.3 is the IP-address of the
localnet machine).

I am having a problem with my ethernet cards. I have two in my machine.
I can ping the interfaces from the machine they are in, but they cannot

voila! I am wondering if anyone can tell me where to find a driver that

Subject: Q: slow: apachebench on Linux 2.0.34 accessing Linux 2.2.x, but fast the
other way round!
Date: Fri, 30 Jul 1999 17:41:10 GMT
Reply-To: [EMAIL PROTECTED]
I'm having a peculiar problem:
Was testing out ab (apachebench) and found that running ab(v1.2) on Redhat
5.2 (2.0.34) got slow performance from Redhat 6.0 (2.2.9) machines. About
6.7KB/sec per concurrent connection!
example
Network= 10baseT
Machines under test:
3 different redhat 5.2 machines (apache)
2 different redhat 6.0 machines (apache)
1 redhat 5.0 machine (apache)
1 windows NT (IIS)
All same collision domain.
redhat5.2> ab -n 100 -c 1 "http://redhat6.mydomain.com/"
Result = 6.7KB/sec
redhat5.2> ab -n 100 -c 10 "http://redhat6.mydomain.com/"
Result = 67KB/sec
redhat5.2> ab -n 100 -c 10 "http://otherredhat5.2.mydomain.com/"
Result = 400+KB/sec
redhat5.2> ab -n 100 -c 10 "http://otherredhat5.0.mydomain.com/"
Result = 600+KB/sec
redhat6.0> ab -n 100 -c 10 "http://otherredhat5.2.mydomain.com/"
Result = 400+KB/sec
redhat6.0> ab -n 100 -c 10 "http://otherredhat6.mydomain.com/"
Result = 400+KB/sec
redhat5.2> ab -n 100 -c 10 "http://NTIISserver.mydomain.com/"
Result = 300+KB/sec
We tried it from two different redhat 5.2 machines and got the same results
against two different redhat 6.0s.
ab on 5.2s has poor results with 6.0 machines!
I looked in dejanews and some people mentioned turning off some tcp options
(sack, window, timestamp). Tried that but no difference. I can confirm that
the options were changed - I ran nmap -O redhat6 before and after and back
again and there was a difference- it didn't recognise the OStype after the
tweaks.
I suspect an incompatibility with the TCP stuff between 2.0.x and 2.2.x but
that shouldn't be the case. It looks bad for 2.0.x to work ok with NT but
not with 2.2.x right? ;)
Any suggestions/help would be much appreciated.
Thanks,
Link.

Subject: window-pc can't connect with linux-pc using mgetty
Date: Fri, 30 Jul 1999 17:39:22 +0200
I use mgetty on my linux-pc. The problem when I dial in with my windows-pc
is that mgetty sends ATA and waits for CONNECT. The last never happens.
After some time mgetty gets a NO CARRIER string and closes down.
My question is: what is going wrong???
