I would like to synchronize both passwords so that if a windows client
changes its password the unix password is changed accordingly.
I am using encrypted passwords now, SAMBA complains it cant change
passowrds because it needs plain text passords in order to tell the old
password to the passwd program.
If i use plain text passwords windows complains changing passwords
was unsuccessful.

Can somebody explain in detail what i am doing wrong?

the data is copied from user space to kernel space using memcpy_from_fs.
Actually fs is the segment reg pointing to user segment. After copying to
kernel space the data is packed in skbuffs( simplistic description ).

I'm looking for an analog modem router that will allow me to connect my
LAN to the Internet using a dialup account.  I also want to be able to
use multiple phone lines simultaneously for additional bandwidth.  What
I have come across so far is Multi-Tech's ProxyServer, Ramp Networks'
WebRamp M3, and UMAX's UGate.  Does anybody know of any similar
products?  I'm particularly interested in routers that support more than

three modems.

Thanks,

I'm facing exactly the same problem with my USR internal modem.
When linux comes up it associates ttyS1 (where the modem is connected)
with IRQ 3 and 0x02f8.

After I ran sndconfig for my Yamaha card (which is working fine),
the modem is having problems. kppp says the modem is busy. With ppp
scripts, the log "Can't get terminal I/O" comes.

The isapnp.conf file contains entries for the modem and has selected
IRQ 3 with 0x02e8. Is this the problem?

Any help appreciated.

TIA

That's right -- HCF (winmodems) and HSP (Soft modem) devices require the
OEM software to replace hardware that is missing on the modem card.  The
specifications and source for this "modem emulation" software are not
publicly available, so essentially, they are Windows-only devices.

There are many.

: when I'am in the inernet via ISP and how can I protect my system.

The most basic way is to remove all the server daemons.  A simpler
way is to configure /etc/hosts.allow and/or /etc/hosts.deny .  Read
about that in "man 5 hosts_access" and "man 5 hosts_options."

But it can be done with expect.  There is an example in the ppp package.
On my Debian system it is /usr/doc/ppp/examples/scripts/secure-card.
Perhaps you could hack it to do what you want.

Subject: RH 5.2 IP Masq Not Working
Date: Sat, 28 Aug 1999 13:13:19 +0000

Ok, I've reviewed the FAQs/HOWTOs and they basically say that my RH 5.2
should do IP masq out of the box, but -- you guessed it -- it's not
working.

Here's what I have

  - eth0 connected to an NT 4.0 system.
  - ppp0 connected to the network
  - gateway set to 38.1.1.1
  - ip forwarding enabled
  - assigned IP address at linux box is 38.26.22.218
  - eth0 IP address is 172.16.0.1
  - IP address of NT system is 172.16.0.7
  - From NT system I can ping 172.16.0.1 A-OK
  - From NT system I can ping 38.26.22.218 A-OK

On this last point the HOWTO says that it means that IP Masq is working,
but I don't think that's correct, since nothing else works.  I can't
ping 38.1.1.1 (or any other Internet site) from the NT system for
example.

Thanks for any clues.

The FAQs don't always mention the following command is required for RH
5.2, and I don't know if this is the problem, but have you tried:

  echo "1" > /proc/sys/net/ipv4/ip_forwarding

If that works, put it in your /etc/rc.d/rc.local script.  Here's what
I've got in my /etc/rc.d/rc.local script for IP forwarding on a RH 5.2
system:

depmod -a
/sbin/modprobe ip_masq_ftp
/sbin/modprobe ip_masq_raudio
/sbin/modprobe ip_masq_irc
/sbin/modprobe ip_masq_vdolive
/sbin/modprobe ip_masq_quake

/sbin/ipfwadm -F -p deny
/sbin/ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0

(Plus some additional firewalling, and the echo "1" command above)

Of course, 192.168.1.0 is my internal network.  By the way, you should
probably use IP addresses from the range reserved for private networks
for your private network.  See the FAQ at
http://www.redhat.com/mirrors/LDP/HOWTO/NET-3-HOWTO-5.html#ss5.1

Hope this helps.

Would recompiling the kernel hurt?  Because I have.  Many times, not just
because of that but because of my sounds.

Hi!

(Cool name! ;-)

To use Linux as a mail server, read and install IMAP to allow sending of
mail, and read about fetchmail
to collect mail from a ISP (man fetchmail).

Hope this solves something! ;-)
