Date: Tue, 27 Apr 1999 18:15:33 +0800
Hi, Anybody please tell me what is the netmask for two subnet?
I only have 16 IPs, I want to use 4 IP for connection to router and
another 12 IPs for another subnet. e.g.
I have 101.202.303.240 ~ 101.202.303.255
I use 101.202.303.252 - .255 to eth0 to router. so,
network ip = 101.202.303.252
broadcast ip = 101.202.303.255
netmask = 255.255.255.252
Is this possible?
But I can't use 101.202.303.240 - .251 to eth1 for another network.
network ip = 101.202.303.240
broadcast ip = 101.202.303.251
netmask = 255.255.255.??? <--- ?
I tried to use 255.255.255.244, but it fail with Multiple device when I
test with traceroute.
Thanks and appreciated.

Subject: printing: remote->local
Hello,
I would like to print from a remote unix comp to my linux comp with a
local printer (which works fine under linux).
After adding a printcap entry and a spool dir on the remote comp I get
this with lpc:
lp:
printer is on remote host pavlov.hug.ch with name HP_pavlov
queuing is enabled
printing is enabled
1 entry in spool area
Fri Apr 23 16:30:10 1999: waiting for queue to be enabled on
pavlov.hug.ch
and lpq sais: "Your host doesn't have line printer access"
I've tried to create /etc/hosts.lpd and /etc/hosts.equiv but without
much success.
What is the format for these files ?
Or is it the lpd that must be restarted with some particular option to
process requests from the network?
thanks for your help
Ivan
P.S.:linux comp is a RH5.1 (2.0.34)

With a passive FRITZ! card, no way. There's no driver for this kind
of emulation for passive ISDN cards at all. Either buy the active FRITZ
card version (there is a CAPI driver for it), or use a simple modem
and then install "modemd" and the approriate Win* clients for accessing
remote modems on your LAN (there was one shareware program called COMT
that did that, but it's now fully commercial) .

I keep getting this error, I have no clue what went wrong
prior to 2.0.35 I had no problem setting up a nis server.
but recently while upgrading my system I get this annoying error
I need help fast!
I reconfigure the /var/yp/Makefile to fit my system.
I initialize the nis server with ypinit -m
I startup ypbind and ypserv
I start checking if ypmatch works, it does
next I check if ypcat works, it doesnt!!
I just get this
ypcat: cant find passwd.byname reason:YP SERVER ERROR
Cant find any errors either in the log files
What went wrong???
What have I missed
It has the same setup as with my last linux kernel (2.0.34)
and the nis server worked just fine.
Please, my hair is getting gray over this
(yeah its prolly a newbie Question, and its prolly I've missed
just something small, but this error made me blind)

If you are on a 255.255.252.0 net, your broadcast 24.112.x.255 may be wrong
depending on x . Check again with the Info your ISP provided and read the IP
Sub-Netting Mini-Howtos.
example x=2
1111 1100 0000 0000
0000 0010 1001 0101
broadcast would be
0000 0011 1111 1111
i.e 24.112.3.255
Hope this helps

the main difference from my point of view:
nfs security is mainly importing-host based (i.e. the exporting system has
to trust the importing system to handle all security aspects within the
shared filesystem itself)
smb security is mainly exporting-host based (you mount a filesystem
with the rights of a user of the exporting system - that is all you ever
get to see). for all i know, the smbfs client for linux allows no further
distinction of access rights within one mounted filesystem
in short:
use nfs for system wide mounts (specially if you have equivalent user/group
environments on the exporting and the importing system).
use samba/smbfs for single-user-mounts where one single user wants to
authenticate himself to a completely different account in a completely
different environment and use shared ressources from it.
at least, that is, how i understand it...

Yes, I came across that bit in the O'Reillly's "Building Internet
Firewalls". In other words, there are no real problems to be expected
if we stop making hosts visible from the Net, and rely on NAT instead?

My problem is a simple one....
I have a reasonably size network at home, and I have one
dedicated line and modem to connect the network to either
my ISP or my works network.
I would like this to be an automatic process for it to either
dial work or my ISP depending on the IP address it is trying
to route to, but is this possible? at the moment my ISP dialup
is automatic using diald but when I need to connect to work
I have to kill the diald process and manually start the work
ppp script.
Please, all I want is the linux server to dialup to either
network on demand....
It can't be too much to ask from such a full OS can it???

What do you have for the following config settings? Here's the ones I'm
interested in, with my own settings in braces:
security [= server]
password server [= nspsrv1]
encrypt passwords [commented out on my machine, I'm not a PDC or login
server]
domain controller [commented out on my machine, I'm just a file server]
domain logons [commented out]
"encrypt passwords" is a big one, as 98 sends an unencrypted payload
containing the password. If you have this set to yes, try setting it to no,
restarting Samba and trying again.
Another one is "domain logons". If you're trying to log into your Linux
machine are *not* in an LANManager domain, then you'll want to have Linux do
authentication for you. If this is the case, set this option to yes and
"domain controller" to be your Linux box.

Subject: Re: Remote booting Diskless Linux Machines
Date: Tue, 27 Apr 1999 14:19:57 GMT
Here's a link to Netboot's installation text:
http://www.han.de/~gero/netboot/texts/INSTALL
Here's the excerpt of what one needs to do:
2.) Configuring for root filesystem on ramdisk
If you want to use a ramdisk as a root device you have to create
a ramdisk image first. Probably the easiest way to setup such an
image is to use a floppy, though you can also use the loopback
device if you are working on a Linux host. First format the floppy
and make a filesystem on it. Next copy all programs and files onto
it which you want to have on the root filesystem of the diskless
client lateron. You should then test your root floppy. To do this
copy your kernel onto another floppy with dd and set it's root device
to floppy using rdev:
dd if=zImage of=/dev/fd0
rdev /dev/fd0 /dev/fd0
Now boot your diskless client using this boot disk. After the kernel
started up, it will ask you to insert the root floppy and to press
enter. Your root floppy will be mounted.
If everything works as you intended, you can now create a netbootable
image. Re-insert the root floppy into your server system (or whereever
this netboot directory is located), and type:
dd if=/dev/fd0 of=ramImage
gzip -9 ramImage
mknbi-linux -d ram -i rom -r ramImage.gz -k zImage -o bootImage
Like above this will now give you a file bootImage with the netbootable
Linux kernel image in it.
