Hmmm, looks like two problems here:

1.  the svc_create and svc_tp_create errors:
Sounds like you rpcbind daemon isn't running.  Start it by running /etc/init.d/rpc start

Why this didn't start up when your system booted is up to you to find out.  I suspect it may be something like the rc script has been removed (/etc/rc2.d/S71rpc on Sol 9)

2.  Init command respawning

You're not gonna like this, but it looks like you may have a hacked system... :-(

/usr/bin/srload is NOT a Sun binary, and isn't on any supplied version of Solaris.  I suspect you have a RootKit installed on your system. Probably the X-Org SunOS RootKit, this is the most common one for Solaris. You can try downloading "chkrootkit" from the net, but this isn't 100% reliable.  Another way to confirm this is if you have the directory "/usr/lib/libX.a".  If you do, then you definately have a rootkit on your system.  This directory hasn't existed on Solaris since SunOS 4.x

The best solution.... blow away you machine and rebuild it and patch it to the teeth.  There is no point restoring from backup and it will be very hard to determine how far back this rootkit was installed or what vulnerability they used to enter your system.

Closey, thanks..


1 As you said, The rpcbind daemon is not running.
when using the command
# rpcinfo -p hostname
got the error below :
rpcinfo: can't contact portmapper: RPC: Rpcbind failure - RPC: Failed
(unspecified error)

I tried to start it by running /etc/init.d/rpc start
nothing happened. :(

2
unfortunately ....
# ls -la srload
total 29500
-rwxr-xr-x   1 root     dba       259832 Jul 12 20:15 srload

and fortunately there is the directory /usr/lib/libX.a

I would like to try RootKit, want to know how to use it...

Thank you very much.

I think you are slightly confused.... having /usr/lib/libX.a is a BAD thing.  You don't want this directory.

Your system has been HACKED and a RootKit has been installed. You don't want a Rootkit installed.  This means someone else has put a backdoor onto your system and they have full control of it and use it for whatever they want, including hacking other machines.  The only way you can fix this is to rebuild your system and patch it.

This rootkit also appears to have broken your rpc.  RPC is very important in the running of Solaris as things like NFS and NIS use RPC.

I think the best thing you should do is to turn off this machine and thoroughly read http://www.chkrootkit.org/  This site will tell you what a rootkit is, and provide you with an app to test for the presence of one as well as a lot of useful links about rootkits.

Hello,
colsey79 is right. I strongly recommend you go to this page: http://www.nipc.gov/warnings/alerts/1999/trinoo.htm and download find_ddos_v42_sparc.tar.Z.
run the find_ddos program on your system to see what (if any) virus type software has been installed on your system.
Generally, it is time to completely re-install a hacked system.

Next time use tripwire; and make sure all patches are up to date.

Sorry dude :-(  

Maybe some OT will be authorized.
