Possibly.



We have two hosted machines with our web host provider, but were not able to
configure Network Load Balancing due to SSL cert.’s being needed on some of
the sites the second server is now hosting (thereby negating our ability to
use the 2 NICs on each machine we are limited to).


Huh? SSL certs should not be needed for port 80 access...



The site we have running on the first server is a vital one, but the machine
needs maintenance and so we’re searching for a solution that could work for
a period of 30-60 minutes, no more. Can Squid accommodate this, even for a
MS platform such as ours?

Been searching all the documentation I could find and could not find the
answer I need on this… many thanks in advance!


~Philip 



Um, is this a once-off. Or a long term backup mechanism?

Static content, or dynamic content that can be cached for the 30-60 
minutes without causing trouble is easy.  Any purely dynamic content 
that cannot be cached at all may have trouble.



To do this with Squid you would need version 2.7, with a cache large 
enough to hold most of the site and at minimum all of the in-use pages 
and files. Set squid up as a web accelerator for the machine thats going 
down. Then shift DNS over to it as primary server.

  http://wiki.squid-cache.org/ConfigExamples

Once that is done the real prep can be started to enable caching of the 
site during the down time. Set up stale-if-error on all objects from the 
hosted sites so they can be served out of the cache even if too old 
during the downtime.


Then use a spider (wget etc) to pull the important website(s) into 
Squid's cache fully just before bringing the web server down.


With all clients going through Squid for some period leading up to the 
outage, there should be no major disruption.


Problems you may face are:
 - not able to cache the whole website (triage the pages to those 
needed most)

 - dynamic pages not being changeable during the outage.

Actually, this is a simplified entry. We may have more than one set of
users, high priority, highest, low, etc. So we would need group
aggregates too.

Not sure. I have now enabled full debugging on "77" which is delay
pools. Will see if I can find anything.

Hardy has 3.0.STABLE7 as latest. If problem persists, will try to
compile and use 3.0STABLE13.

Something like this:

set squid.conf:

Then in logrotate.d/squid (this is just off the top of my head, check 
the docs for corrections):


  postrotate {
squid -k rotate

Re: [squid-users] Delay pool aggregate is very large negative number on upload

[Amos Jeffries]

Prasanna Krishnamoorthy wrote:

Hello List!

We have a simple scenario with a transparent squid proxy and two delay
pools, one unlimited and one limited. When a user in the limited delay
pool uploads a large file (say via Gmail) his Individual-Current pool
becomes a large negative number, and so does the Aggregate-Current
pool. This behaviour is highly offensive, since browsing "freezes" for
all users, until the delay pool Aggregate becomes positive again.


I agree, it may be highly offensive to clients. Why are you doing it?

Personally I'd configure squid with only individual pools. And limit 
each user IP separately.


ie:
  delay_parameters 2 -1/-1  32000/64000



Squid Conf -

delay_pools 2

delay_class 1 2
delay_parameters 1 -1/-1  -1/-1
acl bpool-1 src "/etc/squid/bpools/bpool-1"
delay_access 1 allow bpool-1
delay_access 1 deny all

delay_class 2 2
delay_parameters 2 64000/256000  32000/64000


Why not add here:
  delay_access 2 deny bpool-1
> delay_access 2 allow all

... which means you can get rid of the unlimited pool above.
bpool-1 people will be left without a pool at all, and get through 
without speed limits.




Please let me know what information I can provide to figure this out.
It's pretty easy to reproduce for us. We are also ready to test any
patch (we use Ubuntu Hardy, Squid Cache: Version 3.0.STABLE7-1  - the
latest available in Hardy).

Thanks,
Prasanna.


That said, there does seem to be a problem. Delay pools should not go 
negative at any point.  Is it only happening on POST?

Re: [squid-users] Squid Crashes when cache dir fills

[Wilson Hernandez - MSD, S. A.]

I have approximately 75 users on my lan that continually use that 
server. I will consider your solutions and implement them and test how 
squid behaves.


So, what is the recommended cache size for a squid system running with 
over 75 users?


Thanks.

Your cache_dir line says create a squid cache directory structure 255 wide by 
255 deep and allow it to grow up to 60G. Squid will continue to try and store 
objects into the directory structure until either 60G limit is reached or the 
filesystem - more like as not /var - runs out of space.
If it runs out of space squid is no longer able to write to its log files you 
configured in your squid.conf file. If it cannot write to the log file it 
cannot tell you want happened!


Do you want a nice simple solution?
Add a second hard drive and have squid create its 60G sized cache there.
Make certain logrotate is rotating the normal system logs  and asking squid to 
rotate its logs!


Use df and see just how fuch free space is really available in /var if it is a 
filesystem in its own right.


Another thought?
How many users are trying to access the 'net via this proxy that you want to 
store 60G in a 256 by 256 structure? Last time I looked through the docs and 
faq's there was a good write up on sizing the cache - both hard and soft.

Re: [squid-users] Squid Crashes when cache dir fills

The store system is actually aufs and the partition is 77GB. I don't 
have anything else other than iptables and squid installed on this system.

- ufs is an old store system, aufs will probably give you better
performance.
- How is the inode usage on the disk?
- The disksize is irrelevant, the partition size of the partition where
/var/log/squid resides is relevant. If that partition is only 10G, then
this cache won't work.

[squid-users] Log HTML data and track session

[Squid-Insys]

Hi

Someone know if there is a way to log HTML content from user's using squid?
we have a reverse-proxy and we want to view what kind of data is been
requested in the POST method and the HTML it goes with it.
We also are looking for a way to track the sessions. The IP in the logs
cannot give us the track because users can be IP source translated. The
problem is that we cannot modify web servers code to insert cookies we just
can send them the HTTP requests we received. 
Users are authenticated in the Web Servers, so we need to know what are they
looking for on the Web servers and keep a track of each session.
(For us a session is the time since a user opens a navigator window, writes
on its credentials, carries on a few searches, and closes the window)

Any help will be appreciated.
Regards.

I belive u didn't get it as Amos said read the manuals first  
everything is documented or google for squid instalation u will get  
step by step answer . Moreover I belive your problem is not squid but  
Linux itself . So first step is you go to forums and understand Linux  
that way it will be easy for u

Dear All Squid Users/Experts,


Given an  installed systems with fedora-linux os, how to proceed to  
make

squid proxy server ?


Let me tell you the fact that I am just monitoring the activites of  
squid

proxy server, though I have not myself made it.


I would like to know a few things, if any one of you can kindly let me
know what basic things one must look into to make one squid proxy  
server ?


What are the lines that I have to check/modify in squid.conf file ?

As of now the current df shows up the following status of the disk  
space

in my proxy server.



[r...@facu-pxy /]# df
Filesystem   1K-blocks  Used Available Use% Mounted on
/dev/mapper/PrimaryVol-root
 19838052   9958860   8855192  53% /
/dev/mapper/PrimaryVol-home
 34756272  28916872   4045352  88% /home
/dev/mapper/PrimaryVol-var
 14855176  13219512868896  94% /var
/dev/mapper/PrimaryVol-tmp
  4062912139684   3713516   4% /tmp
/dev/sda1   101086 34837 61030  37% /boot
tmpfs   25342412253412   1% /dev/shm
[r...@facu-pxy /]#



As you can see the /var shows up 94% utilisation.


From my inspection, of the /var partition, I could see that,  
everything is
fine, and the logs are routinely deleted from the system in a  
particular

order as cron jobs.

Please let me know.

Thanking in advance,

jm

I understand that I should not ask this question here but, can
you/someone tell me how do i NAT
the internal imap port 993 to external 993?

I've only one LAN card in my system with ip address 192.168.10.20

why two NICs? do you have more upstream connections? That can be done with
one nic, and one squid instanca can use more than one NIC.

Why do you want that? Maybe your problem can be solver by using single
squid, maybe the using parent/child proxy (as already advised) would  
help

you with that

there's no reason to proxy IMAP, unless you want to sniff it
(which you can even without proxying), or filter for viruses and spam.
See untangle for the latter.

If you want neither one, do simply NAT.

Re: [squid-users] Squid Crashes when cache dir fills

Your cache_dir line says create a squid cache directory structure 255 wide by 
255 deep and allow it to grow up to 60G. Squid will continue to try and store 
objects into the directory structure until either 60G limit is reached or the 
filesystem - more like as not /var - runs out of space.
If it runs out of space squid is no longer able to write to its log files you 
configured in your squid.conf file. If it cannot write to the log file it 
cannot tell you want happened!

Do you want a nice simple solution?
Add a second hard drive and have squid create its 60G sized cache there.
Make certain logrotate is rotating the normal system logs  and asking squid to 
rotate its logs!

Use df and see just how fuch free space is really available in /var if it is a 
filesystem in its own right.

Another thought?
How many users are trying to access the 'net via this proxy that you want to 
store 60G in a 256 by 256 structure? Last time I looked through the docs and 
faq's there was a good write up on sizing the cache - both hard and soft.

Squid is an http proxy and has no means to proxy imap traffic!

Not with squid but it depends on what platform squid is running on.
If it is linux then iptables can solve the problem.
Anything else you will have to solve yourself!
