[pptp-server] High-Uptime with pptpd 1.0.1

[George Vieira]

Upgrade to 1.1.2 and most of your problems will dissapear......... only to
get new problems hee hee ;-)

I don't know why the web sites aren't updated to often and why they don't
recommend usign 1.1.2 version. Development or not... it's the most stable
version of the lot..


thanks,
George Vieira

Howdy,

  I have been testing a  redhat 7.1 <-> Win2k sp2 PPTP vpn.  It has 
relatively low traffic [save for big db updates (50-100/meg at once)], 
and is actually hooked up across a 100Mbps lan currently.   I have been 
using it to test the robustness of MySQL's current 'replication' 
abilities.   Various tests have gone well both for pptp & MySQL.   
However, I have been testing the 'high-uptime' portion of things.   
After about 10 or 12 days of operating I came in to day, and had a load 
of the following messages in my syslog:

<snip>
May 26 23:29:42 widmers pptpd[980]: CTRL: Unexpected control message 0 
in disconnect sequence
May 26 23:29:42 widmers pptpd[980]: CTRL: EOF or bad error reading ctrl 
packet length.
May 26 23:29:42 widmers pptpd[980]: CTRL: couldn't read packet header (exit)
May 26 23:29:42 widmers pptpd[980]: CTRL: Unexpected control message 0 
in disconnect sequence
May 26 23:29:42 widmers pptpd[980]: CTRL: EOF or bad error reading ctrl 
packet length.
May 26 23:29:42 widmers pptpd[980]: CTRL: couldn't read packet header (exit)
<snip>

When I say a lot, I mean 779 Meg.  I rushed to clear out some junk 
before taking a serious look into where my space went.   It is just my 
desktop so I have 'var' on my root volume.  Anyway, the VPN was still 
running just fine, and everything was ok, but pptpctl was running at 
like 70% cpu time, and had accumulated about 2000+ minutes of cpu time. 
 ???  Anyway, I have no idea what would cause this, but anyone know?


Redhat 7.1
Vanilla Kernel 2.4.4 w/MPPE patches.
Downloaded pppd from ... whatever that site is. [I am running 2.4.1] 
w/ppp-2.4.1-openssl-0.9.6-mppe-patch
pptpd 1.0.1



thanks,
  Joshua
