Server :: Does Squid Cache "response Headers" ?
Mar 21, 2010
One of our user inform me about some problems in viewing one site that he does not get fresh objects from site's server while site is updated everyday!! After some investigate and dig on headers I get, I found out in response headers that "date" field is for 2 or 3 last week!! 1- Does Squid cache "response headers" ?If so, when user send "If-none-match" or "if-modified-since" in request header the cached "response header" will be updated?

I recently finished installing Squid 3.1.9 and I think I've done installing correctly with its feature of minor configuration changes. It accepted requests on port 3128 and created and the created some numerical or binary (I guess) files in /usr/local/squid/var/logs, My problem is how can I fully verify if the cache is really storing Internet Files? I've read some forums in the Internet replied to me to try the command: cat /usr/local/squid/var/logs/cache.logSo I did tried it and it gives me this output:
2010/11/11 18:04:49| store_swap_size = 0
2010/11/11 18:04:50| storeLateRelease: released 0 objects
2010/11/11 18:05:41| Squid is already running! Process ID 5458

I'm using squid as a proxy in our organization. My problem is whenever the squid cache folder size exceeds 3 GB our proxy server starts to hang. Is there a way to write a script that it will automatically delete the squid cash when it exceeds the 3GB limit.

I have installed debian to run Squid cache as a caching proxy.
Ive been bashing away now for 2 days and i have managed to install squid (i first tried manually, but that did not work so i used synaptic software packager to install it (from Administration menu)
That went well, thereafter i installed webamin to work with squid in a GUI
I have managed to start squid and added my range of IP addresses to the ACL list
I have added the proxy restriction too.
Now, i tried to test it.
I opened Iceweasel Web browser (on the same machine) and setit to use the Proxy server: localhost and port:3128
That works fine.
But when i try to change the proxy setting to my machines ip (where squid is installed) :
Proxy server: 10.0.0.35 and port:3128
That does not work.
Am i missing something, please help
I then tried to set another windows PC on the network to:
Proxy server: 10.0.0.35 and port:3128
That also does not work.
I also edited the conf file to http_access allow all, but i do not know if i have doen it correctly, but maybe there is another problem?

I have a server that runs on a static IP address with many hosting accounts. I am using the IspCP to manage the different sites. When a mail is sent, the headers include the box's own domain name: [URL]. Now [URL] is no longer active, so if an email from another account: [URL] sends mail, there is possibility that this mail is rejected by the receiver, if the receiver system does rDNS.
The receiving server will check the headers smtp sent from [URL] and come up as a fake, because [URL] is no longer registered. I wonder if there is a way to make the smtp headers reflect only the domain name that sent the mail. Then if joe sends mail, the server should replace[URL] with [URL]. If this is possible, then users that send mail will not get bounced because the rDNS lookup will map [URL] to the ip and the mail will be accepted.

I have followed this guide [URL] to setup a diskless cluster based on ubuntu server. Every thing is fine in the boot process except this:
After the client boots vmlinuz and init.rd, I see some information and after a minute I see:
Code:
IP-Config: no response after 60 secs - giving up
/init: .: line 3: can't open /tmp/net-eth0.conf
kernel panic - not syncing: Attempted to kill init!
It is strange since it gets an ip address when it want to boot. I don't know what is wrong with it.

Have a Java program which simply connects to a server and gets back the response from the website.
When I use it under Windows environment it runs fine and i receive a Response Code: 200,
Response Message: OK but in UNIX i get Response Code 401, Response Message Unauthorized
In Unix I tried to ping the website using the ping command.
I use putty to connect to a Unix m/c. I don't have any permissions to install any programs so could not install any s/w so i could check if i were able to reach the website.
Is it a Proxy Server related issue ? If yes how do i configure it ?

I have installed Centos 5.4 with Sendmail 8.13.8, i have modified sendmail.mc file and compiled to sendmail.cf with following lines
1. TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')
2. Define define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
3. DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
My problem is that when i try to open port 25 with telenet it takes lot of time like more than 1 minute to open session and another 30 - 40 seconds to respond to "ehlo" command.
Also when i try to open telnet session on port 25 in another server it hardly takes 1-2 seconds open session.

I had centos 5-5 server with 6G of RAM and 4 core cpu 3GHZ i installed bind 9.7.1-p2 on my server with multi thread support there are a lot of dns requests on my server , about 2500 Packets/sec and 3Mbit UDP traffic but my server response week to most of them.
For example when i use nslookup or dig command to query Yahoo.com the response from server maybe deliver about 5 Sec or become timed out , but sometimes response time less than 1 sec!
I don't know why, perhaps kernel works week so i decided to do the following :
But the problem didn't solved
I previously had Freebsd with same version of bind and same configuration and everything worked fine.

I know JohnVV. "Install a supported version of Fedora, like Fedora 11". This is on a box that has all 11 releases of Fedora installed. It's a toy and I like to play around with it.

I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?
