Networking :: (Netstat -s) Bits Or Data Packets Transferred Counts?
Sep 15, 2009
Using netstat I can get a lot of network related information which is pretty useful at times. But when I use for example 'netstat -s' it gives me a lot of counts for bits transferred or data packets transferred etc. Now one thing I am not sure of is that for how long those counts will keep rolling and when will they get reset (when I restart the machine?, when I restart the network services? Or if there is some kinda threshold set on it?) How exactly netstat counts those things (I mean what is the source of those counts for netstat).

I have question regarding netstat? When performing a "netstat -s" I receive the following information regarding dropped packets under IP:
IP:
93978695 total packets received
0 forwarded
0 incoming packets discarded
79472157 incoming packets delivered
65235033 requests sent out
29527 outgoing packets dropped
However if I run a "netstat -i" I have no dropped packets whatsoever: (apologies for the table format):

I have a small office network (about 30 machine) with linux gateway (6Mbps internet bandwidth). Every user get only 500Kbps bandwidth, and they use the internet very poor. The internet getting slow lately, and I noticed that there are huge amount of small packets (78 byte, 48 byte) coming to linux machines. My question is: How can I solve which machine(s) sending those small packets? Do you have any ideas with netstat command?

About 7 years ago I setup a Redhat system with 8 serial terminals and 8 serial printers, this is still running but I need to get another system running so the original can be taken down for maintenance. The printers are ancient Newbury data dot matrix wide carriage with 7 data bits receive 8 data bits transmit Xon/Xoff flow control. Now I remember setting the transmit and receive data bits as above but after 7 years can't remember where.

i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it.
i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?

I'd like to represent data in a graphic form and one example is a million bits of data represented as a square .gif of 1 million pixels.
I'm posting here rather than [Art & Imaging] as I'd like to dump 0s and 1s directly into gif|jpg|png or other format, rather than using an application. Even with an application I'm not sure of an efficient way to channel the data.

when I reformat ubuntu, I use AptonCD to save packages and then restore them without downloading anything over again. what I want to know is: I have the 32 bits ubuntu installed and then I downloaded the 64 bits version. If i reformat to the 64 bits one, would the DVD saved aptoncd packages from the 32 bits work on the 64 bits installation?

I manage a small home network of 5-6 PCs and other devices. One of the PCs is used as a multipurpose server, as well as the gateway to outside.
Sometimes, I need to know what traffic goes in/out of my network (for troubleshooting, etc).
Is there a quick and dirty way to forward a copy of all the packets on the external interface to my own ip when I want to?

I'm quite new to linux and I recently (and courageously) upgraded the computer of my work from opensuse 11.0 32bits to opensuse 11.2 64bits.
Well, everything would be quite fine except that I still have some softwares 32 bits that have the 64 bits version available. I know that because, using YaST, I can see by the Installed software section that there are 'choices' of versions for some programs; these versions are 'i586' and 'x86_64', and many of them have the i586 version installed.
So, I wonder if there is some type of auto upgrade all programs which are i586 and have the matching x86_64 avaliable...

Can I install Linux 32 bits on system 64 bits?
For example if I have cpu 64 bits, can I install ubuntu 32 bits?
If yes, all drivers will befor 32 bits, right?

While running some live tests last week I saw an odd situation where netstat appeared to be displaying the wrong PID and process name for TCP connections. I'm trying to figure out if this is just a strange netstat bug or if it could indicate something odd is happening with our software.
We have a main program which establishes a number of connections, including connecting to a JMS server and listening/accepting a TCP connection. The main program also creates a child process which it uses to communicate with another server. On at least three occasions we saw a situation we saw netstat reporting all the expected TCP connections (correct ip/port for both source and destination), however the child process, instead of the main, was listed for the PID. The main process was still running but netstat no longer reported any TCP connections established by the main program. The main program continued to function correctly, the JMS communication continued to work and we believe the other TCP connection was functioning correctly despite the program supposedly not having any TCP connections.
I'm wondering if this could simply be a bug and/or obscure functionality of netstat that I don't understand which would cause netstat to report the child process as 'owning' the parents TCP connections. I don't know how this would happen or why the parent would continue functioning despite the problem otherwise.

While issuing the command netstat -M it shows netstat: no support for `ip_masquerade' on this system. But this system is used as a gateway and iptable rules are set for ip forwarding. Also internet is getting another machine through this machine. What about the message?

I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.

I've been experiencing some home web-server slowdown issues lately, and I wanted to see if it's a problem with the server itself. I'm not sure if this might be the problem, but upon checking netstat -tn, I see over 15 instances of the following:
[Code]...
where 192.168.2.9 is the server's local address, the local address port varies, and the foreign address is the server's web address. If anyone knows what might be causing this and/or how to fix i

Netstat has always confused me. I ype netstat -pl and get this:
Code:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 localhost:ipp *:* LISTEN 1476/cupsd
tcp 0 0 localhost:postgresql *:* LISTEN 13816/postgres
tcp 0 0 *:44223 *:* LISTEN 1288/sshd
tcp6 0 0 localhost:ipp [::]:* LISTEN 1476/cupsd
tcp6 0 0 localhost:postgresql [::]:* LISTEN 13816/postgres
tcp6 0 0 [::]:44223 [::]:* LISTEN 1288/sshd
udp 0 0 *:bootpc *:* 1267/dhclient
I assume that *:* means that any foreign host can connect from any port, but then what does [::]:* mean? and localhost:ipp... what port is ipp? Shouldn't ports be numeric?

We are running a combination of Apache-2 with mod_jk connecting to tomcat workers running on separate hardware.Strange: "netstat -tn" on the Apache server outputs identical combinations of source address, source port, destination address and destination port.
Has anybody else experienced this phenomenon? (I googled and searched LQ but couldn't find anybody else reporting this)Is netstat broken, or is there another explanation?

I'm configuring a CentOS 5.4 workstation. I have been able to apply most of the security that is required. I have met all but one logging requirement. How do you get the count of old passwords associated with users? I don't need to see their passwords just how many times they have changed them. I have set remember to 24 in the /etc/pam.d/system-auth file. I don't know where the file is that contains this information.
