Erfahrungen mit ricmp?

[linuxhanz]

Hallo;



Ich will unseren Webserver (haha Scherz :ugly: ) mit
ricmp konfigurieren.




$ ./ascii2hex %2whata$****in/damn?
253277686174612f64616d6e3f

$ ./ricmpset -x '253277686174612f64616d6e3f'

$ ./ricmpacl add 127.0.0.1 192.168.10.74 accept log


Soweit keine Fehler. es kommt Passwors set, ACL set usw.

Da ist es auch:


% strings /dev/mem |grep ricmp

ricmp_dev
ricmp_ntoa
ricmp_setpwd
ricmp_try
ricmp.c
ricmp_dev_write
ricmp_dev_open
ricmp_dev_close
ricmp_dev_flush
ricmp_fops
ricmp_dev
ricmp_ntoa
ricmp_setacl
c02d5a40 T ricmp_init
c0245520 T ricmp_setpwd
c0245560 t ricmp_dev_write
c02456b0 t ricmp_dev_open
c02456c0 t ricmp_dev_close
c02456d0 t ricmp_dev_flush
c0245860 t ricmp_ntoa
c02458d0 T ricmp_try
c0245990 T ricmp_rmacl
c02459f0 T ricmp_setacl
de/net/ricmp



Das Device habe ich auch angelegt:


/dev/ricmp 10 210


Wen ich mit ping -p + Pattern sende kommen immer Packete an , aber
der Rechner rebootet nicht.

Ich habe den letzten Patch fuer 2.4.20-rcx fuer 2.4.22 angepasst.

Zuerst dachte ich, man muss direct an das Device senden. -> Falsch.

Hat jemand das mal jemand hinbekommen? Mit was fuer ACL's?
