Subject: Re: Help with setting up POP3 server
Well, if it is calling the POP3 server from inetd, make sure that
/etc/inetd.conf is setup properly, and that the daemon binary has execute
permissions (chmod u+x daemon). Then HUP the inetd (killall -HUP inetd
works good for beginners :) ), and everything should be ok. Personally,
I wouldn't run Qualcomm QPOP on a Linux box, but that's your choice. :)
If you are still having more problems, read a FAQ or something. :)

Subject: Windows <---> Linux networking
Date: Wed, 19 May 1999 08:38:59 GMT
Reply-To: [EMAIL PROTECTED]
I'm trying to setup a very small LAN (2 computers).
One of them runs Red Hat 5.2 (kernel 2.2.5) and
the other runs Windows 95 (it absolutely has to,
since the person who uses it can't/won't use
anything else).
I've been trying just to get them to ping each other
without much success. I've set them up with 192.168.1.
addresses, with the Linux box setup to be the gateway.
Now the Linux box is happy pinging itself (192.168.1.1),
but it does not find 192.168.1.2 (the Windows box).
In fact, the arp cache says that the address 192.168.1.2
maps to 00:...:00 -- showing that 192.168.1.2 is not
announcing itself.
The Windows box has been set up with a TCP/IP
service with DialUpAdapter-->TCP/IP with
dynamic addressing, since this is what the ISP
does, as well as another Network Adapter->Tcp/IP
service, whose IP address *is* set to 192.168.1.2
and gateway to 192.168.1.1. However, if I load
up a DOSshell and try to ping 192.168.1.2 (itself)
it tells me the request timed out.
In desperation I installed Linux on a separate
partition on the Windows box. The network ran
quite happily then.
Is it a Windows problem, or a Linux one? And if so,
what could be the cause?
Thanks in advance for any help.
angel
PS No, I can't ditch Windows, much as I would at this
point love to.

Try a newer driver. Recent LinkSys EtherFast 10/100 boards use a Tulip
clone chip, not the original DEC chip. These boards require a more recent
Tulip driver than has been included in any kernel, AFAIK. Try the Tulip
driver support site:

Why don't you compile the kernel so you could pick and choose all the
features you want? You only need the kernel-source-* and kernel-headers-*
rpms to compile your own kernel instead of using stock rpm kernel. Give
it a try and once you get a hang of it, you won't even wanna use the rpms
and start using the tarballs. There's nothing to it.

Can anyone tell me what is wrong?
I setup the /etc/printcap file like what the HOWTO says.
I setup my devices "/dev/hp4 - Text, /dev/ps4 - Postscript"
All other stuff seems to be working....
When I print from Netscape, Postscript files are buffered up in the
/var/spool/lpd/ps directory, waiting to be printed. For some reason,
the stay there for a random amount of time. When it does finally print,
the pages are blank.
This happens to the hp4 device as well.
I have check, so has other programmers check the config files. No one
can find a thing wrong.
Facts:
SAMBA works. I can actually talk to the printer.
Password to the service is correct. Can cat files to printer fine (via
smbclient...)
Server (NetBIOS) name id correct.
It does print after some time, however, pages are blank.
the status.ps4 files in the ps directory says everything worked. i.e.,
10%, 20%, JOB FINISHED, printing, removing from queue, etc.
I will mention. The damn thing worked JUST ONCE. JUST ONCE! After
that, without changing a single thing it quit working.
Any help, ANY would be greatly appreciated.

Is it possible to ping to other hosts? And traceroute works also.
Telnet doesn't work and TCP als not. Then you have the same problem
as I have. And I have no solution to it.

Maybe you can use tcp/ip instead.

Hi all,
in the documentation of kernel 2.2.9 there is mentioned you should enable
"root on nfs" if you want to have your root filesystem on NFS. (Sounds
logical, hm?) ;-)
I have enabled NFS support to be compiled into the kernel (no module), but there
is NO option like "root on nfs" there.
Has this option vanished recently?
System is a Sun Sparcstation SLC (yes, Linux runs on a Sparc, really!) :-)
Can someone give me a hint where this option resides???
Thank you in advance for your answers. Would be nice if you could send a copy of
your reply via mail also. Thanks!

Hi,
I need to use traffic shaper to create a 64k ISDN simulating router.
I've use LRP to create a boot disk which finds 2 ethernet cards. I now want
to restrict the cards by adding a 64k shaper device to both of them, the ony
problem is I can't seem to bind shaper to eth1..
The dialog goes...
'shapecfg attach shaper0 eth0'
(this works fine)
But then
'shapecfg attach shaper1 eth1'
returns
'Shaper: Operation not supported by device'
Any help much appreciated...

I'm guessing that the DialUpAdapter-->TCP/IP is the default
Protocol, so 95 is always trying to ping over the Internet
Under Network Adapter->TCP/IP check the "default Protocol"
or s.th. like that.

I compile SYN cookies into every Linux machine we have. However, this
is the first time it has actually been used. :)
Anyway, is this always an attack and not some type of wierd
misconfiguration? Also, even with SYN cookies compiled in, will the
attack slow down my connection to the internet? I noticed that my
system load was pretty high when I was getting the messages. Also, the
speed of the internet connection wasn't all that great.
I assume that this type of attack is a denial of service attack? Also,
the only protection I have is the SYN cookie option? What else can I do?

Subject: Samba wierdness with mounted filesystem
Date: Wed, 19 May 1999 17:43:08 -0600
Hi,
I'm in the process of upgrading an NT server to Linux. The box
basically serves as a static file server to a small cluster of special
purpose workstations, hosting an array of large (20+ GB) SCSI drives.
Under NT, these drives were shared as pcserv1, pcserv2, etc, and
I'm basically duplicating that (or trying to) with samba. I created
mount points /pcserv1, /pcserv2, etc, and set up my smb.conf file.
Here's the problem: If I don't mount the drives, and say just have
a couple of dummy files in the /pcserv1 dir, I can see them fine from
the client (W95 for testing at the moment, the real clients are NTW).
But when I mount the drives, I get a "not accessible, access denied"
error.
One possible (?) gotcha -- the mounted drives are NTFS, but I'm
running 2.2.5 and can see the files just fine locally. Howcome
samba won't share? (The files are only ever read, so I don't
have to worry about writing to NTFS.)
(Oh, I'm running samba 2.0.3, if that makes a difference)
Help?
