Hi nnaga
STEP 1 :If u are sure about installation of pacakage by using
lslpp -l|grep "bos.net.tcp.client"
case 1: IFCONFIG PROBLEM
Then proceed to step 2:
#lslpp -f "bos.net.tcp.client"|grep ifconfig
you should see the following correct output
/usr/sbin/ifconfig
/etc/ifconfig-->/usr/sbin/ifconfig
you knoe that /etc/ifconfig is a softlink to /usr/sbin/ifconfig
You said you are not getting this output...so let me know
the output of the above command.
case 2

ING PROBLEM
If step 1 is okay ...then proceed to step 2
step 2:
#lslpp -f "bos.net.tcp.client"|grep ping
you should get the following correct output ...if not please reply me with your output
/usr/sbin/ping
/etc/ping-->/usr/sbin/ping
Here /etc/ping is a symbolic or soft link to /usr/sbin/ping.
In both cases issue is same and resolution must be the same.
please reply with your outputs so that I can understand and direct you...
