Subject: FTP server not working
Date: Tue, 2 Feb 1999 12:13:10 +0800
Hi.
I've just taken over administering a Redhat 5.1 linux machine for a small
company network. It dials into the internet using ppp, and it runs squid
and a mail server to serve the internal computers by ethernet. I can telnet
from the internet into the machine fine, but the previous administrator had
either not installed, or had disabled ftp.
the /etc/inetd.conf file had the ftpd commented out, and there was no
in.ftpd file executable on the system.
So, I uncommented out the line in inetd.conf, and copied in.ftpd from
another Redhat 5.x system.
The line in the inetd.conf is :
ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd -d -u755
I did a kill -HUP 237, where 237 is the pid of inetd, and then tried to ftp
to the machine from another.
It looked like it was working - it asked for the username and password, but
then produced a weird error message.
> ftp xxxxxxx.xxxx.com.au
Connected to xxxxxxx.xxxx.com.au.
220 xxxxxxx.xxxx.com.au FTP server (Version wu-2.4.2-academ[BETA-15](1)

331 Password required for www.
Password:
421 Service not available, remote server has closed connection
Login failed.
No control connection for command: Illegal seek
ftp> bye
I turned on the syslog for the daemons on the ftp server, and found these
messages to do with the above login :
Feb 1 15:54:17 xxxxxxx ftpd[12980]: <--- 220
Feb 1 15:54:17 xxxxxxx ftpd[12980]: xxxxxxx.xxxx.com.au FTP server
(Version wu-2.4.2-academ[BETA-15](1) Mon Sep 22 20:49:48 EDT 1997) ready.
Feb 1 15:54:24 xxxxxxx ftpd[12980]: command: USER www^M
Feb 1 15:54:24 xxxxxxx ftpd[12980]: <--- 331
Feb 1 15:54:24 xxxxxxx ftpd[12980]: Password required for www.
Feb 1 15:54:36 xxxxxxx ftpd[12980]: command: PASS password^M
The 'x's indicate the hostname of the computer which is running the ftp
server.
The 'y's indicate my username on my computer running the ftp client.
The username is actually 'www'.
The "No control connection for command: illegal seek" seems to indicate that
the client is trying to establish a control connection to some port on the
server, but it isn't connecting properly. Does anyone have any ideas ? Am
I missing a library, or a port connection or something ?
Thanks.
Chris Severn.

sounds like the card is recognized by the system, but is not configured.
RH5.x has a utility called netcfg, which allows you to point and click
your way through the settup. I am almost certain that SuSE has an equivelent.
That aside, ifconfig is your friend, and route.
ifconfig eth0 up 192.168.1.1
will bring up the ethernet card as eth0, with an ipaddress of 192.168.1.1
route add -net 192.168.1.0 eth0
will add that route to the eth0 interface.
man ifconfig and route for more info on them.
The Linux Network admin guide is freely available on the net, prbably
got a copy with SuSE, search for it, it will be of immense help.

I neeed to implement SSL in a server that I have. I wrote the code for

Brant,
I just got a linux box set up to do masquerading with home.com ip
service with no problems. It may not be the solution you are looking
for, but the "easy" way to get it running is to simple install red-hat
5.2. I installed it, got both nics working, executed the appropriate
ipfwadm commands and away we went. Worked like a charm..no kernel
recompile necessary.

If you are starting a private network in your home or office without
intending to go on the public Internet, except through your Internet
Service Provider:
Domain is baliga.com
Computer #1 is comp1.baliga.com IP address = 192.168.88.10 subnet =
255.255.255.0
Commputer #2 is comp2.baliga.com IP address = 192.168.88.11 subnet =
255.255.255.0
If you are inquiring about a registered domain, check with the ISP in
charge of your domain registration with InterNIC.

If nslookup isn't giving you what you need, then...
Check out www.arin.org to lookup the ip address.
Check out www.internic.net to lookup domain names.

Subject: Remote Devices...
Date: Tue, 2 Feb 1999 15:47:08 +1000
Hi,
I'd appreciate any help with this problem as I'm perplexed as to how I can
solve it.
I would like to get my tty devices to forward echo to a remote device. The
best way to think of it is that my /dev/tty will have some form of link to a
remote terminal server. I assume this link would be via telnet but I'm not
sure how to do it.
I need to be able to talk to modems ( connected to access / terminal
servers ) in remote offices directly...
I am assuming I would need to make some modifications to inittab but not
sure what...
Thanks in advance.

Ron,
I don't have it in front of me, but there is a switch for either diald
or pppd that tells it to record a default gateway in the kernel routing
table.
Had my diald up for over a year now - works great!

Mhz/64MB Ram/2 HD 6.4/Modem USR 33.6 and it serves to another 3 machines

1. How can i configure a DNS Server for a intranet (without internet

Well, lmhosts is a holdover from the MS LAN Manager days and is not
needed on a windows network if you run WINS. WINS is like DNS but for
netbios resolutions. On a small network WINS is way overkill and it's
much more straightforward to use an lmhosts file. My guess is that
the Samba folks decided to call the file /etc/lmhosts for
compatibility's sake. On a big network, you usually maintain a
central LMHOSTS file and either copy to each workstation through the
logon script or you put an #include directive in the lmhosts file on
each workstation which points to a central file server.

Yes I have, look in /var/tmp/.pop/ you will see the users name.
Delete the files and they will be able to collect mail via pop3 again.
I have a cron job running every 15 minutes for my customers to clean

Does anyone have a better idea?

I edited makefile and typed make, the compiler ran using the .c files,
however at the end of the compilation it reported "Error 1".
When I typed make install the installation ran for a short while and
"Error 1" came up again.
This portion of the installation allows installation of the manual
pages, of course it has to be a sucessful install before they become
available.
At this point advice is needed as to what procedure I should follow ,
Any information would be appreciated. In the mean time I will keep
reading as much as I can find about the process.
