Networking :: (Netstat -pl) Foreign Host Can Connect From Any Port (IPP)
May 12, 2010Netstat 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?
Software :: Xorg - Screen Blank After 10 Minutes In Idle State
Feb 3, 2011Xorg - Screen Blanking after 10 minutes. Backlight level lower upon return. This is my .xinitrc file:
Code:
#!/bin/sh
#
#~/.xinitrx
setxkbmap "se"
xmodmap -e "remove lock = Caps_Lock"
xmodmap ~/.xmod
xrdb ~/.Xdefaults
xset r rate 200 25 .....
Code:
LIBGL_ALWAYS_INDIRECT=1
INTEL_BATCH=1
pcmanfm --desktop &
compiz --use-root-window --indirect-rendering ccp
After 10 minutes in idle state (watching a video in vlc or in flash counts as idle time too) the screen blanks. As I mentioned in the title, the backlight level is lower when screen turns back on. This is a new feature of the problem, and might be related to a recent upgrade of xorg. Where is the configuration file that handles the screensaver? And why is it even enabled by default?
Fedora Hardware :: HP PSC 1200 Series Over Network - Printer State Idle
Dec 4, 2009F12 64 bit machine, connects to a Windows share to which a HP PSC 1210 is connected through a USB connection. Printer is set to share, nicknamed "Asterix". When the printer is set up through F12, I select under Network printer "Windows printer via Samba". I browse, find the printer, and click verify. The printer is accessible. Then I finish the installation, ordering a test print. Here the strange things start happening (attached some screenshots to back the story up).
1) No error messages appear that I can find. No cups-errors, no other errors pop up on the F12 machine. The print appears and disappears from the "Document Print Status (Asterix)" window. Only on the Printer Properties page do I see something strange: Printer state: Idle - procession page 2.
2) In the Windows machine, I also can't find any error messages. The print appears in the Printer list, and stays there. The printer comes to life, checks its cartridges, rolls some wheels, and then decides to do nothing more. When I select the print and click on Properties, the default priority is 1, but when I move it up to 99, nothing changes. The only strange thing here is, that the document, according to the Windoze machine, has 0 pages, yet is some 20MB.
And nothing ever happens.
Things I think it's not:
Firewall issue. The print obviously slips through to the other end.
Faulty driver issue. Directly from the Windoze machine, and if plugged into the USB of the F12 machine, does it print perfectly fine.

Networking :: Netstat Displaying Wrong Process Name/id?
Feb 9, 2010While 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.

Sep 15, 2009Using 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).

General :: CPUs Keep Toggling Between 100%idle And 0% Idle
Mar 22, 2011When I run top d 0.5 on my machine and I press 1 to enable the SMP View, I notice that all of the CPUs keep toggling between 100%idle and 0% idle.
The odd part is that when a CPU goes to 0.0% idle, I would expect to see one or more of the other columns peek, but they are not.
What is causing this?

Networking :: Iptables Can't Port Forward (PAT Port Address Translation)?
Feb 20, 2010I'm using a Debian servers, as router/firwall.. I've two ethernet interfaces into the server, one for wan and one for lan. The i use SNAT so my LAN clients can access the internet throgh the debian router. That is working... Now i want to be able to access servers on the LAN site from the WAN site, and i wanna use port address translation (PAT). I have a FTP server running on a lan server, so i'm trying to portward port 21.
iptables -t nat -A PREROUTING -p tcp -i eth1 -d (WANIP) --dport 21 -j DNAT --to 192.168.1.2:21
When people try to access my FTP from the WAN site, they are redirected to the local FTP server, and they are promted for crendentials, but when the credentials are typed, and the local ftp server should answer the wan request, the connections dies.
The wan clients are being promted for credentials, so they are redirected to the local lan server, but after that the connections dies, so i think there is some kind of nat problem, when the local lan server is trying to respond to the wan request..
Here i my iptables script:
#flush table

Networking :: MULTICAST Address And Port - Socket Listen Only On Port?
Feb 12, 2009I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 225.0.0.1/23451 and 225.0.0.2/23452
Receiving on 225.0.0.1/23452 and 225.0.0.2/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [225.0.0.1/23452] take its datagrams from emitter [225.0.0.2/23452] and vice-versa!
