Re: cannot ping localhost after reset kernel parameters
Do a nslookup local hostanem and see how it ersolves its name , if it using the DNS server than there may be an issue , the best way to check this is to rename /etc/resolv.con to some other file and use the /etc/hosts to resolve the name . The check is do a nslookup hostname and once the name is reolved properly thatn may be you can ping to other servers too.
Also what is o/p of netstat -nr is it pointing to the coreect gateway ie deafualt gateway.

Re: cannot ping localhost after reset kernel parameters
Check for various things :
1. /etc/resolv.conf
2. /etc/nsswitch.conf
3. /etc/hosts
4. #ifconfig lan0 ( check whether lan card is up or not )
5. linkloop macaddress ( of the lan card)
6. lanscan
7. make sure that your /etc/hosts contains the following line:
127.0.0.1 localhost loopback

Re: cannot ping localhost after reset kernel parameters
Check your /etc/resolv.conf (if you are using DNS) and /etc/nsswitch.conf.
If you are only using the /etc/hosts file, check that your nsswitch.conf has
hosts: files [NOTFOUND=continue]

Re: cannot ping localhost after reset kernel parameters
Before changing the new kernel parameters back to the old ones, everything worked fine. I could ping, did nslookup, ping from one server to another server, back and forth, no problem.

Re: cannot ping localhost after reset kernel parameters
Did your lan network came up. What were the parameters you modified. Check and see the /etc/rc.log file if the network came up.
Hope this helps.

Re: cannot ping localhost after reset kernel parameters
Start Software Distributor agent daemon
Output from "/sbin/rc2.d/s870 swagentd start:
______________________________________________
Error: swagentd exiting due to initialization error in background process. Check the logfile "/var/adm/sw/swagentd.log" for more information.
I ran /sbin/init.d/net start and it did not return any error messages.
Thanks.
