Subject: illegal port command
Date: Sun, 19 Sep 1999 19:12:00 +0800
My ftp client can do host-to-host transfer. But when I used this function to
direct Host A to transfer a file to Host B, I got "illegal port command". I
understand it is possible that Host A may not allow transferring files to
another host. But when I went to Host B to have a look, I found that the
name of the file had been transferred to the right folder. Since the
filename could be transferred, why couldn't the file's content?
Thanks.

Subject: routing multiple diald connections
Date: Sat, 18 Sep 1999 20:36:47 -0600
I am running a redhat 6.0 server for a home network. I also run several
other company networks which require me to dial into on off hours
sometimes, as well as my internet connnection. I am using diald to connect
to all systems and the internet, with one phone line.
Here is the problem....
I have all of the connections setup and working however diald does not open
the right connection for the address entered. ( It always opens net
connection).
I need to know how to set up routing or packet filtering so it opens the
right connection for the request ie...
telnet companyA.....would open diald connection 1 and
telnet companyB....would open diald connection 2 and
request to public address would open diald to Internet.
Just a note :
all connections other than the Internet connection are to companies with
private ip address.
Any help or suggestions would be very appreciated.

If you are using the "IP Masquerading" feature of Linux you have to do a
"modprobe ip_masq_ftp" as root in order to get FTP working.

Date: 19 Sep 1999 07:36:01 -0500
I am trying to create a local news spool using INN 2.2.1, Suck 4.2.2
using tin as the newsreader.
Suck connects and grabs the news files and they are placed in the correct
directories. Inn runs with no errors being posted to /var/log/syslog.
My problem comes with tin. When I execute tin, it reads the active file
and correctly reports the number of articles for each newsgroup in my
active file. However, when I try to read an article, tin reports
"Newsgroup not found on this server".
Any ideas as to what is going on here?
TIA,

=========================================
Sounds like you want to sync the time on all of the computers on your LAN.
Look at NTP (Network time protocol (www.ntp.org). What you will do is make
one computer on your LAN the master clock, and let it sync to an external
server on the Internet. The other computers on your LAN should be set up
with ntp to look at the machine that got it's time from the Internet. This
is all very well documented at www.ntp.org

Try this at a Linux prompt:
nslookup a.b.c.d
where a.b.c.d is your static IP address as assigned by the cable company.
That should return the name they've given your computer. If it returns
nothing but an error message, then it means that the cable company is
being cheesy and not providing hostnames to subscribers' IP addresses,
which can cause problems with some protocols, so you should complain.
As somebody else posted, there are third-party services that will host a
domain name and list your IP address in their DNS servers, so you can work
around a lame or non-existant hostname provided by your ISP. I've heard
of some cable modem operators who object to customers using such services,
though, so be careful. Likewise, some cable and low-end DSL providers
object to your running a web server on your system, so be sure your
provider doesn't object before you embark on such a project. It might be
safer, and in the long run cheaper, to contract with another ISP to host
your web site under a domain name of your choice (or under that ISP's own
domain name). There are ISPs that provide nothing but web space, at rates
much lower than the ~$20/month that's typical for a dialup ISP.

Sounds like time to learn scripting.
man hosts.allow
o All other lines should satisfy the following format, things
between [] being optional:
daemon_list : client_list [ : shell_command ]
If you telnet into the box as user A then dial up company A (ifup ppp0)
if user B dial up company B (ifup ppp1) etc.
Instead of using diald, you could use that as your shell command.

Hello,
I have just started to build my own linux network server. I will only be
serving 1-3 computers but will have things like shared internet access and
things like that, and shared drives (CDs and HDs). The computer isn't that
fast, 133 with 40mb of ram. Is that quick enough for a small home network ?
Will I be able to set it up as a proxy server for the internet and for file
sharing? Also if I do a server install of Redhat 6 will I have everything
that I need (software wise), I don't have a very much money to spend.
Is there a book that might be worth reading? Also does anyone know how much
it costs to run a computer everyday all day in the UK? The PSU is 200W, I
don't know how much a unit of electricity cost here:-)
Thanks for any help,

Does anyone know if I can use a RH linux server with Staroffice installed on
it to install StarOffice on Win98 machines on the network. Normally
Staroffice is installed on the server and then the clients are installed
from the server install. Sun has no information on this in their
"Extensive" database. I want to use Staroffice to connect the scheduling
and address functions to several windows boxes and several Palmpilots. I
have some ordertaking software on the pilots that only works with ms

Hi,
Is it possible to get a linux box to dial up a NT RAS box that will dial
back for security reasons.
It works in Win98 with normal DUN. Would I write it as part of the pap/chat

Everything that I have seen so far in the FAQ's and howto;s seem to not
include the dialback.
If you have any sugestions or places that I can go look at I would be most

You got pump to work? I never could so I use dhcpc. I would like to see
ALL of this scrip. But what you could do is change all the dhcpc entries
to pump. I've heard they work pretty much similar. Or, another option
could be to mv dhcpc and make a link from pump to dhcpc? Who knows.
There are several options here.

That's a MySQL password error. See the MySQL reference doc, section 6:
"How do MySQL privileges work"?
It looks like either a password is required for user impmgr on host
localhost or that user isn't allowed access to the database being used.

Sounds like a perfect firewall computer. If you take the hard drive out
and run gnatbox lite, http://www.gnatbox.com/ you can use the hard drive
on another computer for more space.

Have those as two different computers. The proxy server (I prefer
IPmasquerading to proxy) should have little to no services running and
NFS is one that tends to be exploitable.
Have your NFS server inside the firewall and share to specific
computers, not to everyone.

Yes. Better yet, do a custom install and install everything (it's one

as root
mount /mnt/cdrom
mount /mnt/floppy
Then as your user cd /mnt/cdrom and read it.
When you're done, 'umount /mnt/cdrom'
