Re: [freenet-support] temp files from gateway
Well, your web browser probably stores copies in its cache ... those copies will in all likelihood *not* be encrypted. But it depends on your browser settings, and of course which browser you use to 'surf'.. When surfin through the freenet gateway, the websites you view get stored on your system along with all the images etc. you view, where are they located? please let me know Thanks! _ Express yourself instantly with MSN Messenger!

The encrypted files are stored in the store. The decrypted files may be stored in the temp directory as well. Which is often in the store, subdir temp.

[freenet-support] Newbie-questions
Hello! I consider running my own node and have the following Questions: (By the way, you really should put some examples about bandwith, traffic and so on in the faq-section!) 1. I´ve DSL with a variable IP that changes every 24 hours. My upstream bandwith is 20 (perhaps soon 40) kByte/s. Can I run a node under these circumstances that is usefull to the freenet-project? Is there more upstream- or downstream-traffic? 2. Is there any difference between these possibillities: a, I run my node 24 hours when I run it, but not every day. b, I run my node all the time, but it has to reconnect every 24 hours and gets a new IP address every time. c, I run my node a few hours every day, e.g. every night from 9 p.m. to 6 a.m. 3. I would by a seperate PC as a server that doesn´t need too much energy. Would a Via CPU 1Ghz be enough? Or a old pentium 3 700Mhz? How much RAM do I need for 20 (40) kb/s? 4. What traffic have I to expect or what bandwith is indeed used all the time of my 20 (40) kb/s? 5. How much HD space do I need? (When a DSL-flat for my node is costing 400$ a year, I don´t want to destroy the performance of my node by having too few HD space!!!) 6. Do you know if its possible to install the software on gentoo-linux? (That is only theoretecal, I´m still a absuolute newbie cocerning linux!!!) 7.Have you any experience in running a node on a rootserver? What CPU and RAM would I need to serve a bandwith of 2Mbit (up and down) ? 8. Are there any mechanisms included in freenet that prefer the distribution of small files like text? Otherwise, freenet could be kept small easily just by transfering some huge files which need a lot of traffic. In other words: I don't want that there are a few people who share there movies and that makes the biggest part of my traffic and slows freenet down.

The default is 256MB, which is rather small, or 10% of available disk space (on windows). I recommend you increase this to a reasonably large size. 20GB is a bit large, but many people have nodes with even bigger stores. 5GB should be useful to you and the network.

Are there any mechanisms included in freenet that prefer the distribution of small files like text? Otherwise, freenet could be kept small easily just by transfering some huge files which need a lot of traffic. If there were, people who want to share big files would simply split the big files into lots of small textfile-sized chunks. Sorry, we have to live with that. Besides which, there is small porn, large porn, small politically interesting sites, large politically interesting videos, largish leaked software... size is not always a good indicator of content. And there is such a thing as cover traffic. Although obviously I don't endorse any illegal files that may be transferred over Freenet (except the Diebold files! ;) ).

People have said that some dialup connections use 256 byte MTUs... Hrm. Dialup. The MTU includes the PPP header is max. 30 bytes, IP header can be a maximum of 60 bytes and UDP is a further 8 bytes.. That's 98 bytes of header, leaving 158 bytes of data. So the header is 38% of the packet? That sounds absurd... Of course, PPP can use header compression on the PPP and IP headers, leaving the PPP header at ~4 bytes and IP at ~20, leading to a 38 byte header (14%), but it's still a small packet, considering that an uncompressed header set over an ethernet (1500) MTU is 6%. On Windows the lowest possible MTU is apparently (http://techrepublic.com.com/5100-6268-1061241.html) 68 bytes, but that's absurd. Since you're supposed to send 576 byte packets anyway if PMTU discovery doesn't work then I'd go for that figure. If things start dropping, or more likely the client's ISP starts sending must-fragment ICMP packets, then throttle back. Of course, if the computer you're trying to connect from has a stupidly low MTU, AND a stupid firewall that blocks incoming ICMP then the user really deserves what they're getting.

Are you saying that hosts are required to support MTUs of at least 576 bytes? People have said that some dialup connections use 256 byte MTUs... Since it says HOSTS MUST NOT SEND DATAGRAMS LARGER THAN 576 OCTETS there is no inherent contradiction when it is *smaller* then 576, me thinks? However, I've searched the net a bit too, and looked at my tuningtools to see what they suggest for dial-ups/ISDN, and I must say, they all seem to agree on a typical 576, indeed.
