Going way back!!! – Turning off dynamic updates to route table in AIX 3.2

We have an old RS6000 running AIX 3.2 that we just cant get rid of... yet. The server is receiving updates to it routing table. I know how to prevent this in AIX versions 4.1 and above, but cannot figure it out in 3.2. Does any one happen to know how to turn this off?

Below are the network options:

test17:/home/root (508)#no -a
dog_ticks = 60
lowclust = 200
lowmbuf = 300
thewall = 6000
mb_cl_hiwat = 1400
compat_43 = 1
sb_max = 6000000
detach_route = 1
subnetsarelocal = 1
maxttl = 255
ipfragttl = 60
ipsendredirects = 1
ipforwarding = 1
udp_ttl = 30
tcp_ttl = 60
arpt_killc = 20
tcp_sendspace = 262144
tcp_recvspace = 524288
udp_sendspace = 65536
udp_recvspace = 524288
loop_check_sum = 1
rfc1122addrchk = 0
nonlocsrcroute = 1
tcp_keepintvl = 150
tcp_keepidle = 14400
tcp_keepinit = 150
icmpaddressmask = 0
rfc1323 = 1
tcp_mssdflt = 512
directed_broadcast = 0
tcp_rtolow = 1
tcp_rtohigh = 64
tcp_rtolimit = 7
tcp_rtolength = 13
ipqmaxlen = 50

Thanks,
Shane

Been some time since I came across a 3.2...

I thought 4.3.3 was old.

Then again, I tried to recover some data off a PC/RT box running (or not running I should say) 2.2.1 last year.

Perhaps you have gated or routed running - try turning that off?

Your routing table is being updated by ICMP redirect packets I believe.

I don't think you can disable that on AIX 3.2

As a workaround: you might want to flush the routing table and reinstall the default gateway periodically, or whenever a specific spurious route appears in the routing table?
