Flushing those routes won't delete them if they're static routes you added. Try route del route address to delete them. Example, route del 113.161.234.37 will delete the route to that host.

I have not add those hosts myself.


I donot know they have anything to do with DNS server.

I changed my root password immediately. is my machine being hacked?


[root@world news-post]# route del 103.161.234.37
SIOCDELRT: No such process

why is that?

Those IP addresses seemed to be owned by either Qwest or ARIN.net so it may have something to do with DNS. I found this out by doing a WhoIs search on arin.net's website. I probably wouldn't worry about it.

What type of setup do you have? Is this connected directly to the Internet or is there a NAT/firewall between it and the public Internet? What services are running on this machine?

I would do whois lookups on all of the addresses attached and find out if they maybe someone on your ISP's netblock and if they're trying to crack you. Maybe run Nessus on your machine to find out if you have anything vulnerable and find some rootkit detectors to run on the machine.

if you really want to remove them then do (for example)
Code:
route del 203.161.234.37 reject

The lines that you want to remove are blocking routes. Perhaps they are there for a reason. Read the route man page for more info before you delete them.

jaa

I did that already and I remove those IP from rc.local.

It is my provious setup causing alarm. look fine to me.

but I could not figure why there is not IP via 137 port attacking me.

i have search goggle linksys port 137 ...etc. no much help. some said leave it.
it is not like that before. very abnormal.
