Re: fedora 3 sending out invalid packets



So is it possible that maybe just samba is broken? I don't really want to do a clean reinstall, I don't have the time. Is it significant that they are invalid?

Ok, so I said I had fedora 3 in my subject, but I'm not really sure what
I have.  I installed fedora 2, and then tried to do a yum update to

fc3 dvd and did an update, and that finished, but x didn't work.  But
that's not the point.  The point is that I'm running ettercap (ON MY OWN

Those ports are samba (right?) and then something else, but anyways the
point is, what do I do and does this error matter?

Those are Samba/netbios ports alright.

I would check for;

1) A trojan or spyware (even somewhere on your LAN)

2) Broken (partly??) NIC card or cable, etc.

3) Driver or module that is bad.

I would try a clean install.
