Hello Murali,

alias eth1 via-rhine
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
alias char-major-108  ppp

I am using pptpd version 1.0.1. I do not have an ioptions file.

The log files indicate I am continually getting this:

Nov 22 15:29:55 server pptpd[16871]: GRE: Bad checksum from pppd.
Nov 22 15:29:56 server pptpd[16871]: GRE: Discarding duplicate packet

Nov 22 18:47:38 server pptpd[17059]: GRE: Bad checksum from pppd.
Nov 22 18:47:38 server pptpd[17059]: GRE: Discarding duplicate packet

As a final not I would like to explain a further discovery. I only encounter this problem when right clicking MS Office documents. I can right click on folders and other file types without a problem. 

Thanks, again.

    I find this in my logs upon connect: 

    Nov 21 22:56:29 server pptpd[15993]: GRE: Bad checksum from pppd. 

    Any idea what might be causing it? 

    And yes it is really copying. 

    Thanks.
