I am involved in a project where we need to convert several
BSDI servers with 1000-2000 user accounts to linux servers.
The problem is that BSDI uses a different password encryption
system than Linux. Is there any way to convert between the two.

Does anyone know how to do the other one: share the modem in order to
direct-dail from the other machines on the LAN? Apparently modemd will
do this, but I havn't found much documentation on it. Anybody got any
better ideas?

Okay. So if identd isn't running, will the remote machine just shrug and
establish the connection anyway; or will it deny the connection because it
can't do proper authentication?
I imagine it could be configured either way by the remote admin, but are
there machines, in practice, that reject connections if they can't
authenticate via identd?
Thanks for the info.

Twice now I have tried to get to my computer from away and havn't been

of buttons that are disabled, including QoS/Fair Queuing. Does any one know how

Currently Tabnet does our hosting, but we own our domain name. This may not
be in the correct realm, but when I notify them that we are going to begin
hosting ourselves, what do I do next...meaning who do I notify that we are
hosting internally? Internic/NSI? Will they spread the word to the name
servers?

I'm trying to get this all setup prior to going online, which is making for
some extra work; get a dial up gateway setup and then change over to T-1
connection.
So my next step is to get a box up and running that has ethernet with static
ip 192.168.1.1 and can make a connection to my ISP via dial up? Then I get
others who will use this box to get out to the net?

Subject: Samba semi-working; Need help with Internet Connection
Date: Tue, 22 Jun 1999 22:41:50 GMT
I'm a Linux newbie that has a three computer network at home connected to an ADSL line
with Dynamic IP addressing. One
computer is a Linux box and two computers with Win 98. The Linux box is loaded with
RH 6.0 and two NIC cards to serve
as a server and firewall. I have two questions concerning Samba and connecting the
two Win 98 computers to the internet
through the Linux box.
First. I was able to get Samba up and running so that all my computers finally talk
to one another and I'm able to see
all of them in Network Neighborhood. My /etc/hosts file looks like this:
# /etc/hosts
192.168.0.1 Linux
192.168.0.2 Laptop
192.168.0.3 Desktop
My problem is is that Network Neighborhood shows my Linux computer as
"ADSL-216-62-152" rather than "Linux" which I
would prefer. I think that this has something to do with the initial bootup because
the prompt after I log in is
[root@ADSL-216-62-152-xxx /root]# (xxx being the client address at that time).
Does anyone know how I can change the
naming of this to read [root@Linux /root]# or whichever user name I login as??
Second. I can access the internet through the Linux box but cannot seem to access it
throught the Win 98 boxes.
Netstat -rn is as follows:
# netstat -rn
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.0.1 0.0.0.0 255.255.255.255 UH 0 0 0
eth1
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0
0 eth1
216.62.152.0 0.0.0.0 255.255.248.0 U 0 0
0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0
0 lo
0.0.0.0 216.62.152.xxx 0.0.0.0 UG 0 0
0 eth0
I know it's probably something real simple that I'm missing on both questions but if
someone could point me in the right
direction I would appreciate it. The How-To on ADSL hookup seems to deal with fixed
IP addresses rather than DHCP and
the Samba How-To doesn't touch on name changes. If you need more info let me know and
I'll post it.
Thanks in advance

Hi:
I'm having the following problem:
I have a mail server ((8.8.7/8.8.7) RH5.0, P200/64MB-RAM
The machine starts to send 8 to 15 ICMP packets to an IP address, then the
ethernet link on the hub start to blink really fast and my network goes
down. The DNS machine does not resolve the names anymore wich make
impossible to send email or use http. I have to reboot he machine.
I'm having this problem for 4/6 days with 2 unknown IP addresses.
I put a sniffer and the only information I got was the ICMP packets.
I tried to ping manually to the IP addresses but I got no reply.
I also made a TRACEROUTE with an expired time result.
Is this a hacker attack ?
any help ?

You lose very little. Other computers lose the ability to gain identity
information from your box.
Generally, places which ask for this information will be ftp sights and
mail servers that your machine connects to. For example, if your copy
of sendmail is trying to mail somewhere else direct then the receiving
MTA might send an ident request to your computer so that it knows where
the mail is coming from. Whether or not it will choose to accept it if
that request is not satisfied is down to the remote end.
Of course, it could also be used by remote computers to find out info
about your computer.
Turn it off. Then, if you find some things stop working, turn it back
on again.

wrong machine.
The machine I looked at (ALS9200?) supported redundant power supplies, and a
buncha disks. doesn't support so many disks. BUt I am following on from my
previous thread that was saying intel CPU/integer performance is better
for the money than sparc. so that isn't so relavant.
But I tried to make the configuration fairly similar on the E450.
Just picked the minimum stuff for each computer: 256 megs RAM, 1 disk, etc.
>As for NT vs solaris...we'll leave that one alone.
I never said "NT vs solaris". I said "sparc vs intel".
OBVIOUSLY, you'd run solaris on both :-)

identd is a service to others. It is a way of finding out which user is

Those lines are the way the IPCP protocol (and similiar protocols as
part of PPP) do work. One side does request an option and if available a
special value of it. So
sent [IPCP ConfReq id=0x3 <addr 192.237.75.1>]
would say: "Please give me the IP address 192.237.75.1!" The other side
will then either:
- disagree to talk about any IP number (ConfRej)
- agree to give you this IP number (ConfAck)
or
- offer you a different IP number (ConfNak <addr newIP>)
Hope it's a bit less slang to you now.
