7/25    I have a MacOS 10.3 box that cannot connect via ssh to Solaris 9
        and Solaris 10 boxes. MacOS 10.2 and MacOS 10.4 work fine.
        Connections to Solaris 8 and Linux (from 10.3) work fine. What's
        up with 10.3 such that it won't work with Solaris 9 and 10?
        \- i ssh from my 10.3 powerbook to s9 and s10 many times a day
           for many months. this is to sun and openssh daemons. so your
           problem is local config and not some inherent interop issue
           probably.
           \_ Can you supply which SSH version numbers you are using? It is
              not confined to any one Mac system or any one Solaris
              system. I can try many different Macs to many different Suns
              and have the same problem, but never with Solaris 8 and
              never with MacOS 10.2 or 10.4. Error is always: "Operation
              timed out." Nothing logged. Tcpdump shows lots of acks with
              no responses.
              \- if you just do a "telnet s9machine 22" do you get a
                 version banner?
                 \_ No.
        \_ I think you are running into the infamous ipv6 dns issue w/ 10.3.
           One way to fix this is add the same nameserver as the primary
           and secondary nameserver.
           \_ I did this and also turned off IPv6 in /etc/hostconfig. No joy.
              \_ Okay, that is VERY strange. Are all the boxes on the same
                 subnet? Maybe this is a routing issue.
                 Can you ping/traceroute the S9/10 boxes from 10.3?
                 \_ Various subnets and I cannot ping or connect to,
                    say, port 25 from MacOS 10.3. I *can* do these things
                    from other OS, including MacOS 10.2 and MacOS 10.4.
                    However, to Solaris 8 from 10.3 is fine. This started
                    after upgrading to 10.3 from 10.2. So far all systems
                    I have tested (3) do this. They worked fine before the
                    upgrade (fresh install, actually) and are on 3
                    different subnets.
        \_ Firewall or tcpwrappers?  -ax
           \_ That are selective to MacOS 10.3?

2/5     I like Adobe Flash. When written correctly, it scales along
        with your browser size. It looks consistent on every single
        browser. It is predictable. On the other hand, I'm not a big
        fan of CSS/HTML, which for the most part, look wildly different
        between browsers, and don't even work consistently or
        correctly at times. So why do so many people (like Steve Jobs)

        What is Larry Ellison thinking? What is he going to do with a bunch of
        legacy Sun hardware that no one uses anymore, its fading workstation
        customer base, and open source Sun MySQL that doesn't even generate
        revenue? I really don't get all this acquisition business.

11/29   I'm experimenting with virtualization, and as a poor college student
        I'm wondering what the best alternatives for virtualization are, and
        how best to cut my teeth on messing with non-linux platforms (or I
        guess interesting stuff on Linux would work too). Right now I've got
        FreeBSD7 running on KVM on my home computer (on a Core 2 Quad), and am
        somewhat at a loss as to how to use it. (More details: bridged

        its global work force, as sales of its high-end computer servers have

9/24    Why is nscd going crazy?  DoS?
        \- back in the solaris say 2.5-2.6 era, it had both some bugs
           (some malformed nis maps made it go crazy) and architectural
           flaws in the IPC/door+threading mechanism. if you are running
           OS-recent, dunno, but you can trace it.

3/30    Question: I just deleted 60 GB of files from an 80 GB disk. The
        disk activity lights were blinking like crazy and I could hear the
        drive crunch while the data was deleted. This is under Solaris.
        Anyway, I think UNIX uses unlink() when files are deleted. Shouldn't
        it just update the free list on the superblock and call it a day?
        What is all the crunching about?
