Re: Creating a 10km wireless bridge...pointers?
Depending upon what your budget is, Tranzeo has some excellent wireless products that are ideal for point-point links. Encryption is built-in and they can be configured for point-point or point-multipoint (just in case the project expands). One problem that you may run into, if both sides of the link are close to the ground, is the "fresnel zone". If one side is higher than the other, this shouldn't be a problem. Two self contained POE radios with built-in antanna should run you about $500 and they can be mounted on standard satellite dish arms. I've also used mikrotik products and have generally been very happy with them. There is a ton of functionality and I actually use two of them for my core routers at my current job. I think for this project they are overkill and there is quite a bit of a learning curve to get them up and running. If you don't plan on deploying anything else, I think that you will find that the tranzeo's are a simpler solution.

List, I have been tasked with getting a DSL connection across about 10km of no-man's-land to a rural location without internet access. Ideally, all traffic inbetween the two directional antennas would be encrypted. (Nice, but not entirely required.) 3Mb/s would be great! Something like: LAN<->BSDrouter<->modem<->Antenna<~~air~~>Antenna<->modem<->DSL I'm looking for general pointers of both hardware and software to achieve this. I'd like to employ FreeBSD as much as is feasible. This is my first WAN network project, so even newbie pointers and general references would be much appreciated. (Hardware suggestions, books to read, etc.) Reliability is of mild concern, simply because I don't want to drive 10km at 3:00am when something breaks. Tips? References?

Authenticating proxy server with fine tuned controls
Hi- I am looking for an authenticating transparent proxy server with tiered access. ie, A user who logs into the proxy can access sites based upon group membership; group1 has unfettered access to the internet, group2 gets filtered access. Ideally, I'd like to be able to setup groups for various sites and add/subtract users to allow access to various internal sites. As a diagram, I'd like to do this: Group1:Unfettered access to internet Group2:Filtered access to internet Group3:Access to internal website x Group4:Access to internal website y If user1 is in Group1 and Group3 they can access the internet and internal website x If user2 is in Group2 they can only access filtered websites. If user3 is in Group2 and Group4 they get filtered internet access and access to internal website y Is their an open-source or commercial product that provides for this type of granular control of access? I've setup squid with authentication before, although it was several years ago, but I didn't need to have that granular of a control set.

Re: Wierd Network problem
Yes, I could use something other than cpanel, and directadmin was actually one of my choices but unfortunately, that decision was not mine. I'm only responsible for getting the software that was chosen to work. My issue with the patch was that it was written for if_bge.c dated in March 2006 and I actually compiled a new kernel using the release from December 2006. Everything that I read about the bug said that it was fixed in the 6.2-release tree so I thought that would be ok. Tcpdumps did show massive amounts of bad chksum's from packets off of the network so it looks as though that was my issue. Not sure why it didn't work after the recompile. I ended up having to install a new card and a linksys gigabit card is working nicely now. Thanks for all of the suggestions.

Re: Wierd Network problem
Yes, I have tried different cables, even different physical ports (although same type of port). There was a bug filed against 6.1 for the bge interfaces that maybe related, although the bug indicated absolutely no network conductivity. There was a patch released and I'm trying to recompile with that patch. I must admit I'm having a hard time figuring out how to apply the patch but once I get past that hurdle I'll see what happens. If I can't ge the bge interface working my next best solution will be to just install another card in one of the pci slots and use that instead. Ideally, I would upgrade to 6.2 but cpanel won't support 6.2 so I'm stuck on 6.1 for the time being.

Wierd Network problem
I have a dell poweredge 6650 installed with freebsd 6.1 and on the local router, everything works great (ie, a computer on a different subnet off the same router can access it fine) but coming from outside of the network access is incredibly slow. My first thought was that it must be a routing issue, but I have two other freebsd 6.1 servers on that same subnet and I can access them fine from outside. I dug a little further and compared the servers that are working with those that are not and these are the differences that I have found. On the servers that are working (dell poweredge 2450's) the interface is an fxp0 and here is the output of ifconfig: fxp0: flags=8843 mtu 1500 options=8 inet6 fe80::2b0:d0ff:fee1:f66a%fxp0 prefixlen 64 scopeid 0x1 inet 64.25.218.2 netmask 0xff80 broadcast 64.25.218.127 ether 00:b0:d0:e1:f6:6a media: Ethernet autoselect (100baseTX ) status: active on the server that is not working: bge0: flags=8843 mtu 1500 options=1b inet6 fe80::211:43ff:fedc:9aa2%bge0 prefixlen 64 scopeid 0x1 inet 64.25.218.10 netmask 0xff80 broadcast 64.25.218.127 ether 00:11:43:dc:9a:a2 media: Ethernet autoselect (100baseTX ) status: active The first thing that i noticed is that on the option line there is quite a bit of difference between the two. So using the command line ifconfig tool I removed RXCSUM, TXCSUM from the bge0 interface. Voila! Speed increased and the server was actually accessible from off net. Unfortunately, as soon as I tried to access any other port, the interface crashes. Eventually the watchdog picks up on that and restarts the interface. But the problem is completely repeatable. The server that I am having problems with is running cpanel 10.9; the two that are working are running the dns-only version of cpanel. I am not picking up any errors in the logs. This could be related to cpanel, or not, I'm not really sure, although it shouldn't be. The other unique thing about the setup, that very well may be affecting is that the router in question has two subnets configured on the internal port. There is a nat'd subnet for our local users and there is the public subnet that these servers sit on. The final resting place for all three is in a datacenter that isn't built yet, so rather than reconfigure everything once that was done I simply routed the final subnet to our office and set it up their. The router is a mikrotik RB112 board which only has one ethernet port so I couldn't dedicate a port for the new subnet. As I said, my first thought was that the problem was in the router, but the other two servers are running fine. Any suggestions?

Re: FreeBSD 6.2 Boot Issue
Sorry if this is obvious but I just did this myself with similar problems. Is your /boot a seperate partition? If so, bsd will not boot. It will happily install but will come back with a no kernel found error or similar. I believe this is because only the / partition is mounted at that point. Hope this helps.

Re: Cant boot fresh install of freebsd 6.2 or dell poweredge 6650
Very newbie mistake, which I finally figured out. That will teach me to read the vendors instructions more carefully than the OS documentation. Basically the problem was that I followed the instructions of the software that I will be installing on this server for the partitioning scheme. They recommended a seperate partition for "boot" and this evidently does not work for freebsd, which makes sense since it probably isn't mounted at boot time. As I was looking through the bsd install guides, I noticed this was never done so I gave that a try and voila!, everything works as expected.

Cant boot fresh install of freebsd 6.2 or dell poweredge 6650
I am a newbie using freebsd and have run into a problem on a new install on a dell poweredge 6650. I am installing to a hardeware raid 1 on an LSI Logic raid controller. The installation appears to go well but after a reboot the freebsd boot manager comes up with F1 to boot Freebsd (or default) and then it complains of no boot loader followed by a "no /boot/kernel/kernel" error. The default boot parameter is 0:ad(0,d)/boot/kernel/kernel I've tried different slices with the same results. I have tried using the MBR instead of the freebsd boot manager. I have tried different bios settings on the raid card (LSI logic in the poweredge 6650). I'm not really sure what to try next. I've even tried to install it on a different machine on a single sata drive with the same result. I am obviously doing something wrong but I can't for the life of me figure out what it is. Thank you for any help or direction you can provide.
