Re: Continuous packet streaming on boot of CentOS 6.3 64 bit
From: Mayur Patil <ram.nath241089 () gmail com>

Problem is that when I connect cable I am able to ping to machine but still
unable to ssh.

When I try to do ssh from other machine, it says connection refused.

Now I connect the cable and reboot system. When the system starts, it
automatically starts

checking packets i.e. packet dump mode.

I think Snort script is preventing CentOS to boot as GUI as well as CLI.

I am pretty sure that this is Snort script problem.

Now what to do ??

Please correct if I am wrong !!

Seeking for your guidance,

Thanks !!

The snort message is as follows:

Initializing output plugins !!

pcap DAQ is configured to passive.

Acquiring network traffic from "eth0"

.

Commencing packet processing (pid=1668)

and stopped there !!

I have unplugged n/w cable and got above output.

Does "shell in" means getting grub console then yes !!


I meant ssh but if unplugging the cable works, that's great.


I can get grub console.

Looking forward for guidance,


I'm guessing that you are still in packet dump mode and that you really
want IDS mode.  Do you know what the command line arguments to Snort are?
 If it is running now you can do something like "ps alx | grep snort" to
see.  You need to add -c snort.conf to run in IDS mode.

Thanks Russ sir for reply.

My problem is I am unable to log into command line mode  i.e.
Ctrl+Alt+F2

and also GUI mode of CentOS. And after that I have to add this path.

Would you please guide me how to do that it will be a great help !!

Can you shell in?  If that doesn't work, try unplugging your network
cable(s).


Thank you !!

Hello,

 I am seeing something like this

 *06/11 11:0246  10.1.46.123:136 -> 10.1.46.255:137*
 * UDP:TTL :128 TOS:8 ID:20 IpLen:20 DgmLen:78 Len:50

* in continuous streaming of packets.
*
*
* *Now I am sure that this is the Snort startup script
problem.....!!

 At the starting I have seen message  *starting snort in packet dump
mode*

 Please help how to disable this mode or disable snort script from
loading at boot time??


*Running in packet dump mode is because you don't have a "-c
path/snort.conf" option on your command line. *

Hello,

   I have stuck on one issue. I am unable to see either GUI or CLI
for CentOS 6.3.

   Description as follows:

   I was just checking my snort script on centos machine yesterday.
So I left machine as it is.

   When I come today, screen location has changed on desktop so I
adjusted and reboot.

   When I reboot it takes much time to boot, so I press any key on
keyboard it shows

   fast continuous streaming, no idea of what, seems like to be many
packets

   Somewhat

   UDP---TLS-----255.255.255.0 ------------------->

    like this. When I try to load the Ctrl+Alt+f2 nothing happens.

    I am also unable to login through Putty but I am able to ping
the machine.

    How to stop this packet steaming??

    Need help please!!
