9/8     I'm using AT&T's @Home cable modem service, two computers running
        win98.  If I buy a cheap switch like the one below, will I be able
        to share a single IP for both machines without setting up a linux
        box for ipmasquerading (ie, will the switch do NAT for me?)
http://www.onvia.com/usa/products/index.cfm?Task=ViewProduct&IdCatalog=196051
        \_ Before you spend money on hardware and time on nat configs and such
           why not just get a second real IP from @home and hook three wires to
           a cheap 10mb hub?  Cost is $5/month, it's a real IP, no configs,
           don't need first machine on to get second on the net, etc, etc.
           It would be "just like having a real network!".  Hassle free, works
           for me.  If you're employed you can probably get work to pay for it.
           All this home nat stuff is cute but it isn't a generally useful
           skill for the real world.
           \_ This is option #2 below, for completeness.
                \_ Sorry, I was in a hurry and forgot to state that I was
                   restating the #2 option below as a "best choice" for anyone
                   with $5/month to spare.  But, yes, that was my intention.
           \_ I'm in the "real world" and we use IP Masquerading on a Linux
              box. It's cheaper than having to purchase a 15 IP pack and also
              acts as a firewall because internal IP's are not exposed. We
              don't have a switch, only hubs, so if we didn't do this there
              would be no way to secure the network.
        \_ one computer would have to act as the gateway and needs two NICs,
           (an internal network, and an external network) the second one
           would use a reserved IP number, and be on the internal network.
           \_ NO! If you get a switch that has IP Masq support, it'll do this
              for you...
        \_ 1) A switch (including that one) will NOT work by itself.
                \_ WRONG. Certain switches have firmware support for this sort
                   of thing.
                \_ it will if you have two IP's, nimrod.
                   \_ Please to be recognizing the phrase "by itself", and
                      then pleasantly looking at number 2 below, and then
                      kindly being less insulting next time.
           Win98SE,
           Win2K Professional and Server (but not Win98) have this thing
           called "Internet Connection Sharing" (ICS).  You need one computer
           running ICS.  This computer will have two network adapters (any
           two will do).  You plug one into the cable modem; the other one
           is connected to the other computer with a crossover cable.
           This second computer has "Obtain IP address automatically."
           Now you can share the connection as long as the first computer is
           on.
           2) A lot of cable places have a feature where they can give
           you more than 1 IP address.  In this case you buy the hub,
           connect both computers to the hub, and connect the modem to
           the hub.  Both computers have "Obtain IP address automatically."
           3) Run Linux IP masquerading.  Same hardware setup as 1).
           4) If you're just running Win98 and don't want a 3rd computer
           to run Linux, download WinRoute Lite and use the same hardware
           setup as 1).
           * IP masquerading, ICS, and WinRoute are all NAT programs.
        \_ I bought the Umax Ugate-3000 router/hub. NAT-based and works
           like a charm, including web-surfing, games, ICQ, everything. And
            saves from not always having to have one computer on to share
           the connection.
                \_ How much $$$?
        \_ Anyone tried the Linksys DSL/Cable router (either 1-port or w/
           the 4-port integrated switch)?
           \_ that's for gay homo travel agent office queers who play
              MS solitaire all day

8/5     It looks like my company has started blocking HTTPS tunneling.
        I used to do this by tunneling SSH through the HTTP/HTTPS proxy
        server, but this seems to have stopped working. Does anyone know
        how the implementation of tunneling detection works, and whether
        there are widely available implementations? We run a bunch of MS
        stuff, so I imagine we're running an MS proxy server or something.

6/28    Q: What are folks using these days for anti-spam measures?  I'm
        looking for something that integrates with my MTA (postfix) or my
        delivery agent (sieve).  Currently I'm using a crufty version of
        spamassassin wired into postfix via amavisd-new.  It's decent, but I
        don't want to be bothered with manually upgrading spamassassin or
        updating rulesets on a regular basis.  Anyone have any experience

4/19    After installing Logitech wireless mouse, my friend cannot connect from
        his PC to his wireless broadband router via a USB wireless network
        device.  It said that it cannot obtain IP address from the router.  Even
        uninstalling the Logitech wireless mouse doesn't help.  Do you know how
        to fix the wireless LAN problem, so that his PC can obtain IP address
        again?

5/23    I have DSL through AT&T. The service was originally established
        through PacBell, transitioned to SBC, and now AT&T. I still have
        my original plan and never converted to a SBC Yahoo! (now AT&T
        Yahoo!) account. I noticed the price will be a lot cheaper if I
        do. Are there any drawbacks? I thought someone mentioned some
        negatives about the Yahoo! tie-in once upon a time.

2/18    My DSL modem's ip address is 192.168.0.1, my internal network
        behind my router is 10.0.0.x. Is there a way I can configure
        the router so I can access the DSL modem from my 10.0.0.x
        network directly without re-wiring? Static routes? I tried it
        but no much luck. I also tried changing my internal network to
        192.168.0.x, but still does not work. Thanks.

1/28    Just switched to Comcast from SBC and generally happy with it.  But
        can someone please explain to me why they are constantly pumping
        ARP traffic through the network?  It seems harmless, but I'm curious
        as I didn't see it with DSL.  It's a little disconcerting to see
        constant traffic on your router, even if ARPs are harmless from
        a bandwidth perspective, and it makes the WAN send/receive light

        access from each computer.  How should the network be setuped?
        Would it be dumb to use static IP for each computer and a
        computer as internet gateway?

8/29    What's the difference between a hub, a switch and a router?  Thx.
        \_ AFAIK, probably be corrected by someone:
           hub: Allows communication on a LAN with bandwith shared amongs all
                the nodes on the hub and maxing out at the max line speed.
           switch: Allows communication on a LAN with bandwith greater than
                the max line speed (point to point)

6/2     I've been to many places and almost every place I go to have
        802.11b/g. However, almost all of them have protected access,
        which I presume they use because they don't want people stealing
        their bandwidth. So here is one idea I think will really
        revolutionize 802.11X... an option in the router that allows you to
        specify the percentage of unprotected bandwidth you are willing to

5/23    Has anyone played with carp/pfsync on OpenBSD? I have a simple
        two firewall setup, one fw running 3.6, the other running 3.7.
        Right now the 3.6 system is the "master" and everything seems
        to work properly except that I can't ping the virtual ip from
        the master system. Any ideas?
        \_ I've seen this with a lot of virtual IP/failover/load balancers.

2/25    What is the smallest (physical and price) cisco router that can
        handle BGP?  It should be able to have more than 256 ram.
        \_ When you say ``handle BGP'', do you mean supports the bgp
           protocol or supports enough ram to keep a reasonable (what do you
           consider to be reasonable) number of routes in memory?  Do you want
           to be peering at PAIX, or do you just need a router to run the T1
