routing / firewall question
by hanasaki 24 Sep '04

24 Sep '04

the network is Internet <=> firewall Linux with two NICs firewall <=> internal network The internal network has hosts with the following: hostA - one NIC smtp hostB - one NIC http/https hostC - one NIC dhcp server hostD - one NIC squid http proxy : port 8080 privoxity http proxy filter : port 8081 privocity forwards to squid squid sends to the outside world should the order be swapped? why? why not? The dhcp server tells clients to route via hostD how can hostD be setup so that it is a transparent proxy? Currently all clients set their http proxy to hostD on the privocity port. I know some IPtables rules will be needed on hostD but dont know what to set. Will routing rules need to be set on hostD? what are they? thanks

Shorewall:newnotsyn:DROP:IN=eth1 OUT= MAC=00:0c:f1:ea:f2:32:00:60:49:02:0a:6d:08:00 SRC=161.114.22.105 DST=xxx.xxx.xxx.xxx LEN=40 TOS=0x10 PREC=0x00 TTL=51 ID=20764 DF PROTO=TCP SPT=21 DPT=2984 WINDOW=32768 RES=0x00 ACK FIN URGP=0 Shorewall:net2fw:DROP:IN=eth1 OUT= MAC=00:0c:f1:ea:f2:32:00:60:49:02:0a:6d:08:00 SRC=192.6.165.119 DST=XXX.XXX.XXX.XXX LEN=48 TOS=0x08 PREC=0x00 TTL=49 ID=26898 DF PROTO=TCP SPT=20 DPT=1459 WINDOW=32768 RES=0x00 SYN URGP=0 There is nothing in my firewall that is set up to block any of these PCs at all. Any ideas of what to check? Mike -- Michael Pratt Nova Blue Inc. http://www.nbmap.com

Re: Anyone seen the new Sun FileSystem
by Brian Kelsay 24 Sep '04

24 Sep '04

I stand by my original goofy take on the pie in the sky filesystem. Maybe it works as stated, maybe not, but you cannot say that all these functions come at no cost. Zero administration, disk pooling (RAID) and checksumming sounds great, but the hardware is still performing the calculations which come at a cost. You may not notice the cost in CPU time or ram initially, but as you accumulate data any filesystem requires more resources. The FAT or index of files grows. This may need to be held in ram like other database tables and indexes are for speed of access. Sun is banking on customers running this on Opteron or other 64-bit processors with large amounts of ram and fast i/o disks. Sure they may be able to do those things as advertised, but to me it sounds like any other product that is the last word in widgets. Don't bank on something like this running on older hardware such as a 1 GHz or even a single processor. See above. Is it really reasonable to assume that this filesystem is suitable for servers, SANs and desktops alike? By the way, they did state in the article that we might someday outgrow this filesystems limits. That is only reasonable. Just look at the explosion of filetrading movies due to P2P and Broadband. Now it is reasonable to have a 160GB or 200GB disk in a new PC.

Why should the Brit's fall behind? No we don't. Windows may be utilized ***in*** nuclear power plants, but the actual control of the plants is by highly specialized software and hardware, and there's no way you're going to convince me that tactical weapons are using windows. I used to do MILSPEC electronics and I've never seen anything that even hinted of DOS never the less Windows being used. Besides Windows would never have the response time necessary to do the course corrections needed for tactical weapons. I will say that this article is very scary indeed, but not knowing what the UKs CMS controls it is hard to say what the risks are. I find highly improbable that Windows is being used for targeting, tracking or control mechanisms in these warships. But if it is, they have serious trouble ahead for them. But then these are the same people that forgot to thaw their chicken before shooting them at train windows. £0.02, Brian

Re: streaming media question

>From what I've read of Icecast, you can set the number of allowed connections. You can also set the bitrate of the file to lower the cost in bandwidth. If you wanted to keep someone from listening to it again, then you might do some things w/ a cookie. Better idea is to just let them download the file and listen multiple times if that is legal with the file you post. You don't really need a T-1 to serve it up unless you want 20-30+ users simultaneously. But I could be wrong. www.icecast.org http://www.icecast.org/docs.php Shoutcast also runs on Linux and can be similarly configured. www.shoutcast.com http://www.shoutcast.com/download/serve.phtml http://www.shoutcast.com/download/broadcast.phtml Brian Kelsay >>> "Brian Densmore" <DensmoreB(a)ctbsonline.com> 09/23/04 02:06PM >>> Got a question. I want to implement a media player on my website. A 30 second audio. I have access to a T1 to serve it up, but I of course have bandwidth limitations for my box and need to be able to throttle the bandwidth used by the media link and also I want to track concurrent users and be able to throttle accordingly per user, or to reject users because throttling X number of users would make it useless. So any one know ways of doing this?
