We are observing this as well in our class B (which I'm not to communicate), from all four addresses listed below and no others so far. Have the owners of these addresses been notified? -g On Tue, 23 Jan 2001, Ralf G. R. Bergs wrote:
Hi there, there's currently a distributed scan going on across our whole class C network (contained in the class B network 131.188.0.0/16.) The scanning machines send TCP packets with a source port of 23. The source IP addresses I've seen so far are 134.53.215.184 (ip134-053-215-184.s215.muohio.edu) 216.22.151.67 (fortress.omnicon.net) 209.220.244.18 (w018.z209220244.chi-il.dsl.cnc.net) 209.240.174.2 (apollo.netwest.com) Anyone else seen similar things going on?
