smit route removal

[Bryan Hepworth]

Hi Everyone

I'm trying to remove a couple of entries from the static routes in SMIT
and not getting particularly far with it. I'm obviously missing
something simple but can't see what. Any pointers gratefully received.

Below is the one I'm trying to delete...

Thanks

Bryan

192.168.1/24 192.168.1.1 U 1 120 en0 - -

Can you post output from netstat -rn

This appears to be net route and not host route,
so maybe you should enter destination address as only 192.168.1 leaving the .0 off !
Of course that may then cause bigger problems because then your gateway may not be routable or touchable, and on and on ....
If that's not the default gateway you want, then maybe you should change the default gateway first , then remove this gateway, and then try again.
AND if this is your correct gateway, then surely the route would be correct, unless your trying to route through multiple adapters or something ?

# lsattr -El inet0
...
route net,-hopcount,10,,0,10.0.0.1 Route
True

# chdev -l inet0 -a delroute=net,-hopcount,10,,0,10.0.0.1

the above command deletes a default route (destination 0)

Hi Brian

Maybe some background information is in order...

What I was trying to do was setup two ethernet addresses on one
ethernet card. The network is changing over from some strangely
assigned ip addresses to 192.168 range. There is already a default
route in place so I won't be high and dry. I've managed to do this on a
linux box, but this is my first attempt on AIX using SMIT.

Well the only way I know to get 2 (or more) ip addresses onto the same controller in AIX 4.3.2/4.3.3/5.1/5.2, and presumably 5.3 is to "alias" the 2nd 3rd 4th 5th .... ip addresses.
I tested with a total of something like 20 aliases before sometime, I think it uses a linked list rather than definitive storage space for the list.

Something like (as root):
chdev -l en0 -a alias4=dottedipaddress,dottedmask
and to remove entry:
chdev -l en0 -a delalias4=dottedipaddress,dottedmask

This is also available from the additional menus available from "smitty tcpip", but can't remember which ones and not near a machine today.

So if your "extra" ipaddress and mask needed to address en0 is 150.140.130.120 & 255.255.255.0
then
chdev -l en0 -a alias4=150.140.130.120,255.255.255.0

Then clients can target en0 with both the primary and alias ip addresses.
Here's a little script you can run to display the ip addresses of an adapter, call it what you will:

#!/bin/ksh
# Script to show the status of all ethernet NICS.
# v6.0 BJC 12/12/2003 Generate list from ODM if entries, instead of fixed list
# v7.0 BJC 08/21/2005 Fix positional parameter problems for AIX 5.2
##############################################################
echo
# Display the headings.
echo "Device\tIP Adress\tState\t Speed"
# Loop thru each device.
lsdev -Cc if | grep Available | grep -v Loopback | while read nicdev dummy ; do
nicnum=$(echo ${nicdev} | cut -c3-99)
# Peel Out the ip address and state.
lsinfo=`lsattr -El ${nicdev} | grep "^netaddr" | grep -v "^netaddr6"`
netaddr=$(echo ${lsinfo} | cut -f2 -d" ")
lsinfo=`lsattr -El ${nicdev} | grep "^state"`
state=$(echo ${lsinfo} | cut -f2 -d" ")
# Get the netstat info.
netstat=`netstat -v ent${nicnum} | grep "^Media Speed Running"`
# Peel out the speed.
speed=$(echo ${netstat} | cut -f2 -d":")
# Display the Info.
echo "${nicdev}\t${netaddr}\t${state}\t${speed}"
lsattr -El ${nicdev} | grep alias4 | while read dum cmip dum ; do
[ "${cmip}" = "N/A" -o "${cmip}" = "IPv4" ] && continue
anetaddr=$(echo ${cmip} | cut -f1 -d",")
echo "+alias+\t${anetaddr}"
done
done
echo
exit 0
