ftp: ftp/tcp: unknown service

[Remy_1]

Hi everyone,

I'm getting this error: ftp: ftp/tcp: unknown service when trying to open up an FTP session locally. I'm getting the same error for telnet.
I get: connection refuesed when I tried to do it from an other host.

Thanks again,
Remy Chau

Hi Remy,

Looks like your /etc/services file got corrupted or these entries got deleted. Do a 'grep ftp /etc/services' and see if you get any output. If this is working for root, then make sure the permissions are correct for /etc/services file. Others should have read permissions over this file.

Make sure those services are present in /etc/services file.

If your file looks corrupted,

#mv /etc/services /etc/services.bk
#cp /usr/newconfig/etc/services /etc/services
#inetd -c

Do you have FTP Service running locally.

Try this:

telnet localhost 21

If you get something like THIS

Trying...
Connected to localhost
Escape character is '^]'.
220 host-12 FTP server (Version 1.1.214.8 Fri Apr 20 07:27:42 GMT 2003) ready.



It shows you are running FTP service. If you get an error

"Connection Refused" means you are not running FTP server.

"nknown Service" means somebody would have commented FTP service definitions in /etc/services.

Hope this helps

Hi,

there are 2 files which play main role in this.
1. /etc/services this file have a list of services and associated port number. this file is used to map service with port number
2. /etc/inetd.conf : this file used to start actually service.

Remy, have your nsswitch.conf look something like this for services.

Example:
services: nis [NOTFOUND=continue] files
