jamie_collins — Thu, 19 Nov 2009 17:16:06 GMT

Hi guys.
Opening port 5555 for Data Protector on Linux box but can't telnet to it.
Modified /etc/services to have:

omni 5555/tcp # DATA-PROTECTOR

But when I telnet into it:
telnet 5555

Doesn't connect

Need help figuring out what I need to do to open this port.

Thanks

Tripwire Nightware on Linux (proc filesystem)

Neo — Wed, 18 Nov 2009 23:18:37 GMT

Hello,

I am having a nightmare with Tripwire on Linux..... I cannot get it to ignore the /proc filesystem, which I want to completely ignore for now

Has anyone here successfully configured Tripwire on Linux and completed ignored the /proc filesystem ?

If so, please reply and tell me how you did it.

Thanks.

Sample junk I want to get rid of .... !! I get tons of these each time I run any update to the database, the config file, run a check, etc. I don't want them at all!

Code:

### Continuing...

The above is a small sample of the hundreds of /proc errors I get with tripwire.... !

Well, I solved it. :D

The problem was that I added a directory to the tripwire that had a very huge file in the path I forgot about. Rebuilding the tripwire policy database failed when it ran into that huge file but the end of the process said "Success!' so it was confusing.

When I removed that object from the tripwire configuration, I could rebuild the tripwire policy database and then the /proc configuration worked.

So, I am making progress on this project .

Project completed :D

Proper permission /etc/snmp/snmpd.conf

itik — Wed, 18 Nov 2009 21:36:57 GMT

Hi All,

I'm hardening my linux. And I came across with this file.

/etc/snmp/snmpd.conf

It's current mod is 644 with root:root ownership and group. Can I make this 640 without hurting the OS? Meaning no public read access. Does other resources need to read to it?

Thanks and more power.

A question with respect to IRQ distribution

sunnyhay — Fri, 13 Nov 2009 17:31:45 GMT

Hi all,

I am a Linux newbie in kernel development. In class I was asked a question about IRQ distribution as followed.
IRQs can be distributed among the available CPUs (in a multiple-CPU system) in two ways:
(1) Static distribution
The IRQ signal is delivered to the local APICs listed in the corresponding Redirection Table entry. The interrupt is delivered to one specific CPU, to a subset of CPUs, or to all CPUs at once (broadcast mode).
(2) Dynamic distribution
The IRQ signal is delivered to the local APIC of the processor that is executing the process with the lowest priority. Task Priority Register (TPR) is used to compute the priority of the currently running process.
So I wonder which one is used, or both (how if so) in Linux kernel 2.6 or higher. I know this is a silly question but I did not find out any clear indication of the IRQ load-balance problem.
Thank you very much!

P25786 hsa03050 1 P49721 hsa03050 1
Q05513 hsa04530 hsa04910 hsa04930 3 Q04759 hsa04530 hsa04910 hsa04930 3

close(f1IN); 

 

open(f2IN,"infile2.txt"); 

@content = ; 

close(f2IN); 

 

open(f3OUT,">same.txt"); 

open(f4OUT,">occurence1.txt");

open(f5OUT,">notsame.txt"); 

foreach my $id (@id) 

{ 

    chomp($id); 

    my $count = 0; 

    foreach my $line (@content)  

    { 

        chomp($line); 

        $line =~ s/(\t|\s{2,})/ /g; 

        while ( $line =~ /hsa$id/gi ) 

        { 

            $count ++; 

        } 

        @line = split(/ /,$line); 

        @count = grep /$id/,@line; 

        if ( scalar(@count) == 2 )  

        { 

            print f3OUT "$line\n";

}

        else

            {

                print f5OUT "$line\n";

            } 

         

    }     

    print f4OUT "$id --> $count\n" 

} 

close(f3OUT); 

close(f4OUT);

close(f5OUT);

The total number of lines in the input file s 243 so once i get two different files and the total of that 2 files shud come 243 but m getting sone 48,000 lines

Killing the tty

thmnetwork — Tue, 03 Nov 2009 01:30:25 GMT

It's happened multiple times and I can't figure out why it's happening or how to undo it, but hitting CTRL-S seems to disable the given TTY on 'nixes of various flavors. Killing the pid doesn't bring the tty back, I end up having to use other tty's until I reboot.

Anyone got some information for me?
