Re: [squid-users] Use cache dir in different server

Right now I have about 40GB of cache that would like to move to the new server. My question is: can I just copy /var/log/squid/cache ( cache_dir aufs /var/log/squid/cache 4 64 255 ) to a different hard drive? and if the new hard drive's config is: cache_dir aufs /var/log/squid/cache 10 64 255. This one 100GB for cache. Would I have problems putting the 40GB cache on to the 100GB? Thanks in advanced for your help. About to put your /var/log/squid/cache in to another drive, you can. Just make sure that you will conserve all permissions (use tar to store the files, and extract then on the other drive). About change cache_dir entry from 40GB to 100GB, I did something like this, and my cache wasn't loose. I THINK that you can do this. (Sorry by my poor english)
Re: [squid-users] 2 cache_dir on the same squid server ?
Em 27-12-2009 14:17, Hung Nguyen escreveu: hello folks, Can I specify 2 cache_dir directives for one squid server? I meant two cache_dir on 2 different disk to avoid disk failure ? Thanks! Yes, you can. You can specify how many cache_dir's you want, each in the same partition, or in different partition or even in a different drive. But, it will not avoid problems if you have a disk failure. If the squid process try to write in a cache_dir, and this is not available (imagine that your drive is down, due to a failure), it will crash... But why are you worried about a failure? Are your disks failling?

Do you have any advice for me in this situation: 2 cache_dir on different disk is better or just one cache_dir on a disk with just one partition in it? Ok... about the event of a bad day with your disks, I think that the right thing is to write a kind of daemon script to analyse the availabity of partitions, and if some of them are down, rewrite squid.conf without it and restart squid quickly. And about your situation, 2 or more cache_dir on different disk are better, 'cause the squid process can parallelize I/O requests, improving the transfer performance. (And sorry if I said some incompreensible thing, 'cause I'm brazilian and I still have a poor english)

Re: [squid-users] questions on squid cache

How can I remove cache older than 1 week (same logic as log rotation) thanks in advance 1. Both. This line is about the cache stored on disk, but the squid also has a cache on memory, that you can set in a line like cache_mem 128 MB 2. I did not understand... what? 3. Your old cache is removed by the refresh pattern. Look this: refresh_pattern -i \.jpg$ 10080 90% 10080 It means that every file ending with jpg will stay on the cache 1 week (10080 minutes).

Re: [squid-users] squid (without transparent mode) + Gateway + Authentication on same machine, is it possible ?
Em 04-09-2009 07:16, Sachin Malave escreveu: I have configured Squid as transparent proxy server same machine is working as gateway also. I found that authentication is not possible in transparent mode. Is there a way to configure squid at same gateway without transparent mode but should support authentication. Thank you sachinm (I will advise that I'm brazilian, so sorry my poor english) Man, this is impossible! In transparent mode, the browser don't know that there is a proxy. How can you call functions to authenticate in a thing that you don't know that exists? (understand that is impossible?) You need to choose: Transparent OR authentication. Or, you have another option: Use forced proxy (redirect you 80 port to 3128). Your computer is the gateway so, if you use forced mode, everyone that try to access the internet will see a proxy error, (and so, is forced to enter in options and put the proxy address).
