Anyone knows please help, thanks

can you try and ping the ftp server and from the error it looks like the ftp server and client are on diff subnets

dwarf007 · 10-20-2004, 01:25 AM

The below IP address is the my FTP server computer IP

I ping this from my LAN computer

Code:

[root@localhost eugene]# ping 192.168.1.185
PING 192.168.1.185 (192.168.1.185) 56(84) bytes of data.

Both FTP server and client in different subnets? So what so i do now?

Thanks for the help....

What is the IP adress of the computer you are pinging from? Post the output of
ifconfig -a
and
route

Have you tried a different ftp client?

nitin_batta · 10-20-2004, 06:56 AM

Do you have IPtables on and what are yo using the sit0 int for.

dwarf007 · 10-21-2004, 08:59 AM

how to check my "IPtables on"? sit0, i wasnt understand what is the thing.

sit0 Link encap:IPv6-in-IPv4

The sit0 i mentioned earlier is from the o/p of ifconfig -a from the FTP server.

BTW if you dunn need it you can anyway shut it down.

Code:

#ifconfig sit0 down

Iptables can be shutdown using

Code:

#service iptables stop

in case of Redhat

Or to just view what rules you have you can use

Code:

#iptables -L

dwarf007 · 10-23-2004, 07:31 AM

What is this for?

Code:

[root@localhost sbin]# /sbin/iptables -L

Chain INPUT (policy ACCEPT)
target     prot opt source               destination
                                                                               
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
                                                                               
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

I had solve the connection of the FTP client to FTP server. Actually the problem is from the Linux internal firewall. I didnt enable FTP. About the connection is solve now.

Here is another error for me when my LAN client PC try to search dir in FTP server

Code:

[root@localhost root]# ftp 192.168.1.xxx

can i know what is going on? What is the next step i should do?
Anyone knows please help...
Thanks....

i too have the same problem but i am unable to down sit0 by using the below command:

ifconfig sit0 down
and after checking it by ifconfig -a
it still shows sit0

TimothyEBaldwin · 04-10-2010, 01:18 PM

ifconfig -a shows all interfaces irrespective of whichever they are up or down.

** after bringing iptables service down, I am able to access from local machines..

#service iptables stop Resolved the issue...

mikeus · 06-08-2010, 11:07 AM

Such an issue occurs when the 'ip_conntrack_ftp' kernel module is not loaded. To work with iptables enabled you need to configure the system's init scripts (e.g. via /etc/sysconfig/iptables-config on RedHat-like Linux) to load it on system startup.

Thanks, for the suggestions, its exactly working fine, once again thanks
