The solution is to either stop the router from redirecting ICMP traffic or
to patch the kernel to prevent modification of routing tables.
#dbx -k /vmunix
(dbx)patch icmp_rejectcodemask=0x20
quit
Original query below :
----------------------------------------
We are encountering a strange routing problem . Intermittently , the system
modifies the routing table information .
#cat /etc/routes
default 192.168.1.1
#netstat -rn
Routing tables
Destination Gateway Flags Refs Use Interface
Route Tree for Protocol Family 2:
127.0.0.1 127.0.0.1 UHL 10 560643 lo0
129.64/16 192.168.1.254 UGD 0 22 tu0
192.168.1.30 192.168.1.30 UHL 293 13865076 tu0
192.168.10/24 192.168.1.1 UGS 4 383414 tu0
192.168.10.25 192.168.1.1 UGHS 1 10042 tu0
209.219.209/24 192.168.1.254 UGD 0 10 tu0
Once in a while , the static route to 192.168.10 subnet changes to a dynamic
one
192.168.10/24 192.168.1.254 UGMS 2 204336 tu0
Because of this ,users on the 192.168.10 subnet cannot reach 192.168.1
network.
192.168.1.254 is also the nameserver.The routed and gated daemons are not
running.
When this happens ,I manually add delete the dynamic route and add the
static route:
route add -net 192.168.10/24 192.168.1.1
Please help me find a solution to this problem.
Thanks
Pravin
