Speed up Proftpd login for all users

[linuxfast]

Some people (including me) may find that when logging in to proftpd, there is a short pause at the start of the connection.

I use flashfxp and dreamweaver for transferring files via ftp and this small pause can be quite annoying when making small fast changes to files whilst developing sites.
The pause occurs when proftpd is trying to identify the remote username.
In the conf file, IdentLookups may be set to off but this is not for all users.

Edit: /etc/proftpd.conf

In the <Global></Global> section add the line:

IdentLookups off

Don't forget to restart proftpd with:

service proftpd restart

Be aware that the only thing that will change is that the "AuthenticatedUserID" column in the xferlog will be empty.

Thank you, the speed thing is one of the reasons why I wanted to use pureftpd.

[zarkann]

I will try this and tell you.




EDIT:

It was already at identlookups off.. i'm using it also to upload via total commander in linux. it seems fast but i wanted to look if i could get it to connect faster.

thanks anyway :p

[linuxfast]

identlookups off IS already in the file but not in the <global></global> section.

Put it in there as well.

[zarkann]

yeah, it work well , thanks :)

Also add in configuration:

UseReverseDNS off

and restart proftpd

For Ubuntu 6.10 add the following to the end of the file. <Global></Global> section doesn't exist.

<Global>
IdentLookups off
</Global>

restart: /etc/init.d/proftpd restart

Thanks a bunch, folks! I, too, was missing the <Global> tags.

For Ubuntu 6.10 add the following to the end of the file. <Global></Global> section doesn't exist.
It needed to be added to my Debian 3.1 setup too, and with UseReverseDNS off as well, it has made a vast improvement.

does switching IdentLookups off make it less secure?

Also what exactly does UseReverseDNS off do?

Thanks,
Alex

No. See http://www.proftpd.org/docs/directives/linked/config_ref_IdentLookups.html
Also what exactly does UseReverseDNS off do?
See http://www.proftpd.org/docs/directives/linked/config_ref_UseReverseDNS.html

Basicly it means that in in your logfiles and debug output you get to see DNS hostnames instead of IP addresses where available.

HTH,

EDIT: fixed a typo.

[alexillsley]

will this only speed up login?

Thanks for the tip! Logins are near instant now. (had a 10 sec or so delay before.)
