[moOd] | | Description: | | I've found that inetd on (*atleast*) Debian distribution of LiNUX crashes | when port 13 (daytime) / port 37 (time) is "half-open scanned".. This sounds a lot like the antiquated SYN, RST DoS problem older Linux inetds were vulnerable to. Send a SYN to an internal service, and immediately follow it up with a RST packet. inetd would become unstable and die after the next connection. | I'm not skilled enough to write the code-piece for you to test this out, | but most of the new portscanner include this type of scanning method. | (scantcp 1.32, sirc, etc.) Phrack 49-07, the `Vengeance` module. ftp://www.phrack.com/pub/phrack/phrack49.zip Be warned. It is ugly, ugly code. At any rate, I was led to believe that this problem was fixed ages ago in some netkit rev that escapes me. -- temptation is worthless, suffering is the coin of the realm
