JDS can't ftp into system but can ftp out
 

Hi

I installed JDS on a laptop smoothly. I can ftp to other systems but cannot ftp or telnet into my laptop.

I get the following:

ftp: connect: Connection refused

telnet: Unable to connect to remote host: Connection refused

I looked in /etc/services:

ftp-data 20/tcp # File Transfer [Default Data]
ftp-data 20/udp # File Transfer [Default Data]
ftp 21/tcp # File Transfer [Control]
fsp 21/udp # official is File Transfer, ftp use no udp
ssh 22/tcp # SSH Remote Login Protocol
ssh 22/udp # SSH Remote Login Protocol
telnet 23/tcp # Telnet
telnet 23/udp # Telnet

which looks to me like the ports are open???

Any help would be appreciated!

To see if the ports are open run:The /etc/services just describes the services and theér corresponding ports.

Now what?
 

Thanks,

Don't see them listed here. How do I turn them on?

You can edit your /etc/inetd.conf and uncomment the respective lines. Also comment the services that you don't want to run.

OK did that and telnet now works but ftp does not although I do get further. The connection is made and then lost:

ftp 131.154.48.96
Connected to 131.154.48.96.
421 Service not available, remote server has closed connection

I installed gftp and believe ftp is a standard part of the install (JDS/Suse)

Any thoughts?

I've seen this error when you open the ftp service through /etc/inet.conf, but either you don't have an ftp daemon installed, or it's not configured correctly.
