Title: sme8.6 Sark Server V3.1 Error messages in Logs "No target machines/networks"
Post by: ajkeane on January 09, 2011, 06:27:44 AM

Hi I have been getting these error messages in the logs since 9.50 this morning after a reconfigure.

I had installed the following contribs prior to the reconfigure.

phpsysinfo
Openvpn bridge and phpki
kplaylist
SMEserver-dar2
Awstats

They show up every 5 minutes.

No target machines/networks specified!
QUITTING!

Just wonddering if anyone can point me in the right direction to isolate the issue.

Cheers

Tony

Hi Tony

It's a message which comes out of nmap when it has been given an incorrect parameter list.  This particular instance of nmap is being called by the sark/sail network sniffer (/opt/sark/scripts/perlarp.pl) which gets run every 5 minutes by cron.d/sark. 

What does the output of ifconfig eth0  give?

Kind Regards

S

Sorry for taking so long to come back to you.

The output of ifconfig eth0 is

eth0      Link encap:Ethernet  HWaddr 00:14:D1:1A:4F:32
          inet6 addr: fe80::214:d1ff:fe1a:4f32/64 Scope:Link
          UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
          RX packets:538215 errors:0 dropped:0 overruns:0 frame:0
          TX packets:549750 errors:0 dropped:0 overruns:0 carrier:0

          Interrupt:177 Base address:0xe000

I also ran this on eth1 as this is my external interface

eth1      Link encap:Ethernet  HWaddr 00:16:76:86:95:F8
          inet addr:203.97.103.229  Bcast:203.97.103.255  Mask:255.255.255.0

Hello Tony

The sniffer doesn't like ipV6.  You can simply turn it off. Just comment out line 2 in  /etc/cron.d/sark.  This means that the "Orphan" search (in extensions.conf) won't work.

Kind Regards

Must we replace line 2 in /etc/cron.d/sark

Code: [Select]

*/5 * * * * root perl /opt/sark/scripts/perlarp.plwith

Code: [Select]

# */5 * * * * root perl /opt/sark/scripts/perlarp.pl?

Yes - that's the one.

It will stop it from sniffing the network every 5 minutes.

Kind Regards
