Telnet and ftp problem

[giropizza]

I had installed the telnet and ftp server under linux mandrake 8.1.
the problem is that both servers response time are very high, after 15 seconds they response and after they're very fast but I would like to minimize the delay time.
How I can do this???
It' s not a problem of the pc becouse the Samba server response immediately.

Thanks.

Look in your log files and see if there is a problem with the reverse IP mapping.
Could not reverse map address 10.5.1.101

If this is the case then edit your hosts file and add that host in there.

I've got the same problem.... but the client doesn't have a static ip address, so adding the host in the hosts file is not the solution....

There may be an option in the FTP or telnet server configuration to make it not do a reverse mapping of IP address to name.

Check the relevant manpages for your FTP server or telnet server.

Or, consider not using FTP or telnet at all, since both of those protocols send your password over the network in clear text (along with the entire telnet/FTP session). If you install the openssh package, you get an SSH server, which can handle both ssh and sftp clients (these use SSL connections, and have the same functionality as telnet and FTP, respectively). If your client machine is Windows, then look at Putty (not sure if putty can do sftp, though).

Of course, if you understand that clear-text passwords are a Bad Thing, but you still don't mind, then feel free to keep using FTP/telnet.
