Dear All,

I'm trying to understand how TCP is working in linux kernel, I've been reading this lxr.free-electrons.com/source/net/ipv4/tcp_input.c#L3685", and flylib.com/books/en/3.475.1.124/1/ and I'm interested in how many timers are accessing one data structure, like retransmission queue is being accessed by retransmit timer and also by another processes when the ack is actually received, is spinlock/mutux used in here.
And the above made me think about another question. which is what will happen if ACK is received at the same time retransmit timer reached 0 and interrupted the first thread, what will happen then?

last week i decided to install puppy linux, lupo 5 something. i am mostly happy with it, should have installed linux years ago. however, i had no real firm idea on what to do with my second computer,( my laptop 1G ram, celeron M - dell inspiron 1200)
.
that was last week. now this week I have decided what i want to be doing on this computer:

1. running a web LAMP server so i can build drupal and wordpress cms sites on it before uploading to my vps
2. use sdk/ide software to build mobile web sites and apps
3. practice running a emailing hosting list using an open source mailserver software.
my goal is to run my own mailing lists for my business instead of hiring mailchimp or aweber.

(i dont know if you actually "practice" mailing list on a home computer, please fee fee to correct me on that.
anyway, my question
did i make a mistake choosing puppy? will it run web servers and sdk software? (i am new to this software, and know nothing about it.)
its there some other linux that will work better/more efficiently?

Hello there,

I'm new to linux and I do really need steps-how-to-Fix regarding issues I encountered in CentOS v6.0 x86_64 when I tried to issue make command for iscsitarget-1.4.20 (can not use scsi-target-utils as an option because openQRM uses only the iscsitarget the 3rd party package). After I extracted the tar files and cd to /usr/src/local/iscsitarget-1.4.20. I issued command as follows:


[rootmyschooproject 1.4.20]# make

But then it's running on the worst computer ever made for Linux.

Hi,

I have two questions:

1. Whenever I type the exit command, I receive the following message
   
   
   Quote:

   ---

   [BTEP: PID=8204 exited with code: 0]
   exit

   ---

   And then it just hangs there. I then have to go to the application's menu and close it. Is there a way to make it close completely whenever I type exit?
   
2. Whenever I type clear or reset, the commands are still in the window. Is there a way inside the terminal to clear the scrollback, so I can't scroll back up to see it?

I'm using the Terminal Emulator Pro app for Android.

Thanks,

Rich

Hello all,

It's my first post here, I have a BIG problem!

I'm working with Centos Release 5.8, sending e-mails on Interspire 6, using kloxo and qmail.

Last week, I received a list to send a campaign containing a lot of inexistent e-mails.

Now, Interspire can't process the bounces, because the inbox from my account can't enter.

I want to process this bounces, to delete the e-mails that doesn't exists.

The error message is: "Erro no Servidor: STATUS: Fatal error: malloc: Cannot alocate memory.

I'm trying to open on Roundcube and Horde.

Can anybody help me?

Hi, my name is suvois and I am a new member. Glad to be here.

Does anyone know if Debian needs /tmp already while booting in case the tmp folder is part of de swap partition?

# df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 36G 14G 20G 42% /
udev 1005M 0 1005M 0% /dev
tmpfs 202M 724K 202M 1% /run
/dev/disk/by-uuid/6c64a692 36G 14G 20G 42% /
tmpfs 5,0M 0 5,0M 0% /run/lock
tmpfs 404M 220K 404M 1% /tmp
tmpfs 404M 388K 404M 1% /run/shm
/dev/sdc1 97G 2,2G 90G 3% /media/22b8b2bc
/dev/sdc3 817G 268G 508G 35% /media/extern

Because i want to move my temp folder to my external hard drive (/dev/sdc3) using a symbolic link while i am not sure WHEN in the boot process my system is able to mount that external hard drive. I don't want to take the risk that my system needs that folder during boot time BEFORE it is able to mount that specific drive.

Hello,

I'm new to linux and using fedora 16'. I've installed a couple of themes via gnome-tweak-tool, but after doing such and using them, whether i have the themes on or not, my icons have all disappeared from the applications list on the popout window that appears when you mouse to the top left corner.:confused:

All my menu icons and favorites task bar icons are working, it's just those in the list.

Any help would be appreciated.:D

Im trying to understand the inner workings from a linux gui, but I still got some unanswered questions.

I know gtk uses xlib to draw their widgets.
I know xlib communicates with the xserver.
But how does the xserver draw to the screen? Does it talk directly with the graphics driver? Does it use opengl? Does it use anything else?

--thanks

Hello,

I am building a linux image for AM1808 processor with ARM9 core.

When I include OHCI-HCD as module in the kernel, I have error build later when building modules.
The error is :
ERROR: "da8xx_syscfg0_base" [drivers/usb/host/ohci-hcd.ko] undefined!

If I don't include the OHCI-HCI, the modules build succed and I can write the builded image + modules to my board succefully.

Any ideas about this problem, because I must include OHCI-HCD in order to communicate with USB devices.

hello..
i have recently switched to scientific Linux 6.2.. i am unable to install the HP 1020 plus driver ..i have tried the instruction given on HP site..

but it is showing installation can not be completed..:(

pls help ..how to add printer ...:?
thanks

It's either a 750GB 7200RPM SATA hard drive, or a 256GB SSD.

Which one should I use? Would the smaller SSD be worse than a larger regular hard drive? Or does the performance boost make up for this?

I was thinking about trying out Gentoo.
Is it Linux or BSD?
I've read that is uses port trees I was wondering how that would compare to how Arch is done.
I currently use Arch on all my systems know. I love the configure ability of it. but the updates are kind of a pain because of the lag of my internet. I use satellite internet. I was wondering if trying out the port tree way would work better with my internet. I don't want to go back to other Linux distros I've used because I'll get bored.

Thanks for the help.
