I'm not sure, but the second "-m length --length 20" is redundant. You only get to that table if this condition is true. What I'm not clear about the length module is if it is the rule that gets limited or something else. If it's the rule, then this would drop any packet over 20 bytes after there have been 5 per second.
Do you want to limit it by IP address? Then I recommend you use the "recent" feature:
Hi Friends,
I am having a funny problem with grep. When I run
grep 'expr' file.txt
things work fine. But when try to get the line number using the -n option, i.e,
grep -n 'expr' file.txt
I get a message, "grep: 0652-226 Maximum line length of 2048 exceeded."
If the line has more than... (3 Replies)
Hi All,
I am running a IPv6 UDP server, which is bound to in6addr_any. When I send a packet from a client to the link-local address of any interface on the linux box, the server accepts the packets. But when I send the packets to the global address the server doesnt pick the packets.

I am trying to use the following code:
awk '{s=$0;if(length(s) < 750){getline; s=s " " $0}printf("%s\n",s)}' filename
but an error shows that 'awk' is too long. Is there a limit to the awk length function? and what could be an alternate solution for long fixed width records?
The code... (3 Replies)
Hi all,
I am new to Linux kernel.
we have a c file that counts the no. of sends and received packets in each interface, and indicate the user about the error/drop ration of incoming and outgoing packets.
in our Linux box , the incoming packets are dropped at random interval.
we have our... (1 Reply)
hello,
can anyone suggest how to delay the incoming packets ??
or how the packets are prossed inside the kernal and a way to make the packets wait a while??
it wud be vry helpful

I am looking for an iptables command to allow incoming UDP packets for my Linux server
also is there a command I can use to set the default action for outgoing packets to accept?
Thank you (1 Reply)
Hello, I'm trying to route all packets arriving at a particular interface by entering the same interface
the virtual interface eth1: 2 and now everything is routed by default gw configured on eth1.

Hi folks,
I have a debian server running an Apache daemon on the eth0 interface. Now from time to time the server has to open an openvpn connection (tun0) to other networks to get some data from there. During this period the Apache is no longer reachable under it's IP address on eth0 because all... (6 Replies)

spray(1M)spray(1M)NAME
spray - spray packets
SYNOPSIS
count] delay] length] nettype] host
DESCRIPTION
sends a one-way stream of packets to host using RPC, then reports how many were received by host and what the transfer rate was. The host
name can be either a name or an internet address.
is not useful as a networking benchmark, as it uses unreliable connectionless transports, UDP, for example. can report a large number of
packets dropped when the drops were caused by sending packets faster than they can be buffered locally, that is, before the packets get to
the network medium.
Options
recognizes the following options and command-line arguments:
Specify how many packets to send.
The default value of count is the number of packets required to make the total stream size 100000 bytes.
Specify how many microseconds to pause between sending each packet.
The default is 0.
Specify the number of bytes in the Ethernet packet that holds the RPC
call message. Since the data is encoded using XDR, and XDR only deals with 32 bit quantities, not all values of
length are possible, and rounds up to the nearest possible value. When length is greater than 1514, then the RPC
call can no longer be encapsulated in one Ethernet packet. In that case, the length field no longer has a simple
correspondence to the Ethernet packet size. The default value of length is 86 bytes, the size of the RPC and UDP
headers.
Specify class of transports.
Defaults to See rpc(3N) for a description of supported classes.
