Entries in Firewall Log
Hi All, I'm hoping that there is a lister with good knowledge of the technicalities of the internet. In my logs, there are many entries along the lines of:- Jan 22 22:01:16 tedsnewmacpro Firewall[99]: Stealth Mode connection attempt to TCP 192.168.1.67:56039 from 76.74.254.118:80 and Jan 22 19:28:49 tedsnewmacpro Firewall[99]: Deny netbiosd data in from 172.16.162.1:137 to port 137 proto=17 The second is, I presume, some internal matter between the Mac system and the ADSL router, but the first worries me a little. I've checked many of the IP addresses on whois.domaintools.com, and discovered Amazon, eBay Adobe (amongst others). Amazon I know offers server services to other organisations, but why should ebay, Adobe or in fact anyone try a Stealth Mode connection to my router? Do I have cause for concern?

Re: Entries in Firewall Log
the ip address 76.74.254.118 belongs to wordpress.com, which looks like a blog hosting site. do you have a blog there, or were you reading a blog from there?

Here's a quick checklist to see if your mac is vulnerable to outside attack: 1) Do you have any sharing services turned on in the sharing panel, or any services installed and available through other means (like bitorrent clients, database servers like mysql and the like)? if No, you're not vulnerable. If yes, continue. 2a) Does your Mac have an externally accessible IP address? (something other than 0.n.n.n, 192.168.n.n or 172.16.n.n-172.31.n.n) If Yes, you're possibly vulnerable for running services. Make sure that you keep OS X up-to-date, and limit the sharing options in the various advanced sections of the shared services (like remote login, etc) If NO see 2b. 2b) Do you have the ports used by these services forwarded by NAT on your router? If Yes, you're possibly vulnerable for running services. Make sure that you keep OS X up-to-date, and limit the sharing options in the various advanced sections of the shared services (like remote login, etc) for the forwarded services. (ie: if you're forwarding port 80, http access, to run a web server, but not port 22 for ssh, remote login will not work at all from outside your router, because it doesn't know where to send packets destined for port 22.) If No, then you're safe. The firewall log lets you know every time a firewall rule denies a connection; you'll see a lot of them (a LOT of them if your IP address is an externally accessible one) None of this will affect connections YOU make outside of your LAN, but if you answered no to all three questions, you're essentially invisible to the outside world. -- Bruce Johnson Wherever you go, there you are B.

Re: Best MacOS x on a G3 BW?
Speaking of Panther, wasn't there a software download that enabled right-clicking on an Apple mouse---by holding down the click a little longer?

January 2012 From: seeker jesselorenstj...@gmail.com To: G-Group g3-5-list@googlegroups.com what if any would be the ideal version of macOS x to install on g3 bw with maxed ram? i am a huge fan of opensource, but i have fallen head over heals for mac osx and would like to keep these machines as such so any help? I’m running Mac OS X 10.4.11 Tiger. My BW has its original 350 MHz G3 processor, and I maxed out the memery 4×215 MB PC100 DIMMs to 1 GB. Sady I do rely on 10.4 because of internet functionality: I use TenFourFox. I also have a Cube G4 with 450 MHz running Tiger. BTW TenFourFox on a G3 with some fancy must-have extensions (like NoScript and AdBlock Plus) also put the speed brake on it. You just feel that it is too much for this old little bugger! My experience: the bottleneck is the 350 MHz processor. But even with a faster one it wouldn’t be the same experience as it is on, say, a G4 Dual 1GHz running Tiger or a G5 Dual-2 GHz with at least 2 GB memory running Leopard. The second problem that the BW has is the absence of an AGP bus. PCI just isn’t fast enough for Quartz Extreme. Under heavy I/O load (i.e. because I’m copying files on the USB bus -- USB 2.0 expansion card -- PCI bus -- CPU -- IDE channel) graphics becomes snatchy. Without Quartz Extreme (with the original ATi Rage 128 PCI graphics card) it will be snatchy anyhow. The best OS? I can see Mac OS 8.5.1 (the original bundled OS) rocking on it! Mac OS 8.6 or 9.x is maybe the best choice if you want to go for speed. Or a slim Linux/BSD distro. (But which one? Is there one for PowerPCs?) Mac OS X 10.3 might also be an option, but there is just soo much great software that requires at least 10.4 to run… 10.3 just makes you feel bad about your decision. 10.2 will do as well, but I heard that 10.3 is even faster than 10.2 was. Also, 10.3 is the first to feature all that usability that you expect when going for Mac OS X. The backstep to 10.2 just feels like loosing something. Well, it did to me: I’ve tried. IF you don’t go for speed, 10.4 is propably good for you.
