hi guys

 

anytime i try to reply to a PM from someone on this forum i get an error (after 10 or so seconds)

The following error was encountered:

 

* Zero Sized Reply

 

Squid did not receive any data for this request.

Quote:11.51 Why do I sometimes get ``Zero Sized Reply''? 

This happens when Squid makes a TCP connection to an origin server, but for some reason, the connection is closed before Squid reads any data. Depending on various factors, Squid may be able to retry the request again. If you see the ``Zero Sized Reply'' error message, it means that Squid was unable to retry, or that all retry attempts also failed.

 

What causes a connection to close prematurely? It could be a number of things, including:

 

1. An overloaded origin server.

2. TCP implementation/interoperability bugs.

3. Race conditions with HTTP persistent connections.

4. Buggy or misconfigured NAT boxes, firewalls, and load-balancers.

5. Denial of service attacks.

 

You may be able to use tcpdump to track down and observe the problem.

 

Some users believe the problem is caused by very large cookies. One user reports that his Zero Sized Reply problem went away when he told Internet Explorer to not accept third-party cookies.

 

Here are some things you can try to reduce the occurance of the Zero Sized Reply error:

 

1. Delete or rename your cookie file and configure your browser to prompt you before accepting any new cookies.

2. Disable HTTP persistent connections with the server_persistent_connections and client_persistent_connections directives.

3. Disable any advanced TCP features on the Squid system. Disable ECN on Linux with echo 0 > /proc/sys/net/ipv4/tcp_ecn/.

 

If this error causes serious problems for you, Squid developers would be happy to help you uncover the problem. However, we will require high-quality debugging information from you, such as tcpdump output, server IP addresses, operating system versions, and access.log entries with full HTTP headers.

 

If you want to make Squid give the Zero Sized error on demand, you can use the short C program below. Simply compile and start the program on a system that doesn't already have a server running on port 80. Then try to connect to this fake server through Squid:

 

#include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <sys/types.h>

#include <sys/socket.h>

#include <netinet/in.h>

#include <arpa/inet.h>

#include <assert.h>

 

int

main(int a, char **B)

{

struct sockaddr_in S;

int s,t,x;

s = socket(PF_INET, SOCK_STREAM, 0);

assert(s > 0);

memset(&S, '\0', sizeof(S));

S.sin_family = AF_INET;

S.sin_port = htons(80);

x = bind(s, (struct sockaddr *) &S, sizeof(S));

assert(x == 0);

x = listen(s, 10);

assert(x == 0);

while (1) {

struct sockaddr_in F;

int fl = sizeof(F);

t = accept(s, (struct sockaddr *) &F, &fl);

fprintf(stderr, "accpeted FD %d from %s:%d\n",

t, inet_ntoa(F.sin_addr), (int)ntohs(F.sin_port));

close(t);

fprintf(stderr, "closed FD %d\n", t);

}

return 0;

}

A cabbie picks up a nun.

She gets into the cab, and notices that the very handsome cab driver won't stop staring at her. She asks him why he is staring.

He replies: "I have a question to ask you, but I don't want to offend you"

She answers, "My son, you cannot offend me. When you're as old as I am and have been a nun as long as I have, you get a chance to see and hear just about everything. I'm sure that there's nothing you could say or ask that I would find offensive."

 

 

"Well, I've always had a fantasy to have a nun kiss me."

 

She responds, "Well, let's see what we can do about that: #1, you have to be single and #2, you must be Catholic."

 

The cab driver is very excited and says, "Yes, I'm single and Catholic!

 

OK" the nun says. "Pull into the next alley."

The nun fulfills the cab driver's fantasy with a very passionate kiss.

 

But when they get back on the road, the cab driver starts crying.

 

"My dear child," said the nun, why are you crying?"

 

"Forgive me but I have sinned. I lied and I must confess, I'm married and I'm Jewish."

 

"That's okay, My name is Kevin and I'm on my way to a Halloween party."

hi all, why is it that everytime i try to install ubuntu on a dell{(even w/ live cd)at least with every dell i've tryed) as soon gnome starts the screen goes black (like power save mode) and i get a "out of frequency range message"???

thanks, gus

What continent do you live in? I'm presuming none of you live in Antarctica :) , if so you'll have to post separately.

last night i got the idea to dual boot my Dell. all was going fine utill i relized that durring the format i had also set it to erase my 2 backup jumpdrives witch i left in the computer.(i can't beleve i did that) Of course thay had all my homework on them (due on tuesday). anyone know of a free easy program (prefurably windows) to recover the lost data??

 

now for the next prob.

 

when installing ubuntu my screen displays "out of frequency range", when starting gnome. WHY?

 

 

thanks,

gus

"good times"

just testing out the new smileys.

hi all,

 

In order to expand this site further than 'just being forums' I have put a lot of work into the following section of linux-noob.com

 

[/url]http://linux-noob.com/review/

 

please check it out and notice that it is missing reviews of the following distros

 

gentoo

mandrake

debian

slackware

ubuntu

 

If you feel that you can write a descriptive, interesting review of your experiences with any of the above distros (or any that have not been mentioned), then please let me know and if it's good enough it'll be published here :)

 

I'm looking for reviews that can if possible follow the same format as this review

 

[url=http://linux-noob.com/review/suse/10/]http://linux-noob.com/review/suse/10/

 

it's not that hard to do, take some time describing your experiences setting it up, getting it to work the way you want on your hardware, and anything else that takes your fancy, screenshots would also be appreciated

 

I really do hope some of you can help linux-noob.com grow here, and the 'review' section is an important way of getting the site noticed by the already established linux news sites...

I am currently trying to pull in information on adding a Mandriva machine to active directory from start to finish. I've seen different write-ups, mostly using the text config files (although there was a good one for Suse using their Kerberos 5 config GUI).

 

While I am trying this out with the school's lab, if anyone has any suggestions or pointers, please feel free to chime in. I want this to have complete screen shots and plenty of information for us to use at any time we need.

 

Now, I did notice the ability to choose the authentication method while installing Mandriva 2006, but I haven't yet found any direct means to change that after the first-run. I will be doing some digging this weekend, and I'll be trying this out on Monday.

 

Thanks!

I'm trying to setup Bind9 so that people cant point their dns server addresses to my box and do lookups off my server, but still have them able to query my dns server for the domains its authoritive for.

 

My named.conf

 

acl bogusnets {0.0.0.0/8; 1.0.0.0/8; 2.0.0.0/8; 192.0.2.0/24; 224.0.0.0/3; 10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16;};

options {

directory "/var/named";

version ":P";

blackhole { bogusnets; };

allow-recursion { none; };

};

zone "xyz.ca" {

type master;

file "data/named.xyz.ca";

allow-query { any; };

};

 

The only way I've been able to stop people from doing lookups off my server is by setting recursion to none. I would like to have my localnet to have the option of doing lookups off my box so I need a more suited way of controling who does lookups off my box.

 

I have read about views and I wont be serving different content to my localnet so I dont think I require them.
