    Hi,

    Recently I have installed a poptop/RADIUS and Squid on a box.
    the problem is that clients disconnected rapidly by 629 and some times 800 errors.
    I read the message log as bellow:

    --------------------------------------
    Sep 14 16:28:17 mx2 pptpd[7600]: CTRL: Client 172.16.2.54 control connection started
    Sep 14 16:28:17 mx2 pptpd[7600]: CTRL: Starting call (launching pppd, opening GRE)

    Sep 14 16:28:17 mx2 pptpd[7600]: CTRL: PTY read or GRE write failed (pty,gre)=(6,7)
    Sep 14 16:28:17 mx2 pptpd[7600]: CTRL: Client 172.16.2.54 control connection finished
    ------------------------------------------------

    where may be the problem?

    Regards,

    Looks like a problem with the GRE tunnels

    Heyyyyyyyy I found it!!!!

    Hi,

    I found that pptpd-1.3.3 can work with ppp-2.4.3 not ppp-2.4.4 that has installed on fedora 9. So I installed pptpd-1.3.4 from source and also comment out directive "logwtmp" in pptpd.conf. So it now work excellent.

    I found it on : http://www.members.optushome.com.au/~wskwok/poptop_ads_howto_4.htm

    very usefull source!

    Good lock,
