I'm trying to capture packets with WireShark on 2 port ranges.
This syntax is not working :
Quote:
bash-3.2# /usr/sbin/tcpdump -ttttvv udp portrange 8500-8600 and portrange 5060-5070
There is no output...
What is the correct syntax for defining multiple port ranges ??
I've googled til my brain went boom... So the short story goes; I have lots of ip address ranges in multiple files which need to go into an iptables firewall... Sounds simple right?
Example of files:
1.0.1.0-1.0.1.255
1.0.1.0-1.1.0.255
[code]....
I am trying to remember the procedure used to determine the ip address range when given a network address and its subnet mask. Does anyone have any documentation on the steps that are done to accomplish this?

View 6 Replies View RelatedI am currently running Debian 6. I would like to know if there is a way and how i would go about blocking a certain IP range from connecting to my server within a certain port range. Say for example.
i want to block ip range 123.123.123.* from connecting to my server on the ports 33000 - 43000. But, i want to allow them to connect on any other port range, and i want to be able to allow connections from my server to the blocked ip range on those same ports. so, blocking incoming only on the above port range.
using iptables.
As awk programmers may know, we can print range of lines with awk, from an initial pattern until a final pattern as follow:
Code:
awk '/Initial_String/,/Final_String/' inputfile
Well, I have this inputfile:
Code:
[code]...
Once having those elements in that way within an array(a[]), I want to be able to manipulate the array (a[]) and copy its elements
to another array (b[]) in different order (all lines joined in a single line separated with commas), as follow:
Code:
Category,Adventure,Titles,Robinson,Crusoe,Saturday,Authors,Daniel-Defoe,Ian-McEwan
Only inserting the missing "array" coding and based and follow the code I've written Not needed to create a new code to do it with other method.
I have a series of input files formatted like this:
Code:
RTREVF, KOG3266 = 111
RTREVF, KOG3294 = 130
RTREVF, KOG3295 = 177
WAGF, KOG3307 = 107
JTTF, KOG3320 = 174
Each line represents a portion of a data matrix. I want to convert the numbers after the "=" to the range of that partition in the matrix such that the output file looks like this:
Code:
RTREVF, KOG3266 = 1-111
RTREVF, KOG3294 = 112-241
RTREVF, KOG3295 = 242-418
WAGF, KOG3307 = 419-525
JTTF, KOG3320 = 526-699

View 2 Replies View RelatedI have a linux (Slackware) machine and the time/date is like, June 23rd 2003, 10:00am (It's 11 here) and I am not able to set the time to have it correct. I change the timezome to Montreal but the time is still wrong.
Is there a way to force it to sync with my domain controler or even another online NTP server?
I'm just wondering what the limits for time are. I have a program that always takes exactly 20 ms, so I assume this is the lowest it can measure, but I want to see if there's some sort of documentation of this.

View 3 Replies View RelatedI admit this has been a particularly bad year for me, but it isn't THAT unusual by my standards. I typically spend I would reckon quite honestly about 70-80% of my time with computers just fixing stuff up that either I broke or was broke in the first place. Usually it's the latter by some considerable margin. That's really inefficient, isn't it? I just wondered what others' experiences are of this phenomenon. Obviously I don't do computers for a living or I would have starved years ago. So what is the Panel's consensus view on the percentage of wasted time we should expect to spend, on average, "running just to stand still" on maintenance tasks?
View 5 Replies View RelatedOne of our clients uses a mobile client, which "helo"s with a non-resolvable hostname (which contains the correct IPv4 address in the name but does not resolve). I'd like to be able to config PERMIT "joeblow@mydomain" when the helo-names "*.mobilepool.carrier.net". Can anybody give me a hint how to do this, if it is even possible?Right now it just rejects based on not resolving the HELO name.

View 2 Replies View RelatedIt takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?
I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?
View 14 Replies View RelatedI've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

View 9 Replies View RelatedI am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code:
hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.
