[Planetlab-users] SMTP tunneled over HTTP - legitimate?

[Markus Iturriaga]

Hi - our network admins just notified me that their intrusion 
prevention system is blocking some traffic to pl1.cs.utk.edu because it 
matches a well-known exploit involving tunneling SMTP over HTTP. The 
relevant CERT advisories are here:

http://www.kb.cert.org/vuls/id/150227
http://www.kb.cert.org/vuls/id/868219

If this is legitimate traffic generated by one of the researchers in 
PL, I can ask them to stop blocking it. Please contact me directly at 
the email address below if this is part of your research/use of the 
planetlab nodes.

Thanks,

Markus
