Networking

It seems that OpenBSD people has then patched cvs vulnerablity, though. In this version, OpenBSD has pf(4) improved a lot!

TCP is vulnerable?! Yes if your system relays on persist TCP connections, for example, routers supporting BGP. CERT has released a advisory about this.

It seems that sina’s bad-brainly designed anti-spam system is going to do more foolishnesses. By applying their RFC-violence, they did not blocked spam and in addition, make normal mail slow and even not deliverable.

Bruce M Simpson has added Daniel Hartmeier to the active committers’ rank. Daniel is from the OpenBSD campaus and is one of the authors of OpenBSD’s stateful firewall, pf(4).

Robert today has sent a headsup to current@, claiming that he will merge his changes on p4 to cvs soon.

Dong CHE has told me that mail from mail.freebsdchina.org has been bounced back because it was listed in rblplus.mail-abuse.org. From the query page I found mail.freebsdchina.org were listed in mail-abuse.org’s DUL by mistake (I believe so because the mail.freebsdchina.org block is not owned by dial up user).

I am really disappointing about this news. An earlier discussion on this topic could be founded here.

This is a complex problem. A peer to peer system consists many self-determinating nodes is hard to control, and when it goes crazy, it will be easy to launch a distributed denial-of-service (DDoS) attack.

Here are some of my thoughts, well, they are not mature and some of them might be misleading, but I will write them here.

cd /usr/ports/net/pptpclient
make all install clean && rehash
