VMware is one of them: RedHat's 'system-config-authentication', compared to 'authconfig-tui' for non-X use, is another. Others, like virt-manager and OpenOffice, do not operate in text mode at all. |

Works OK here. I have of course got single address holes through the firewalls. Someone would have to access an ISP central router to spoof my address. Since I use the connection very rarely, the chance of an existing connection being hijacked is very low. |

Until, of course, you come to someone's attention who doesn't like you, or a script kiddie who monitors your connection and picks up the packets saying 'password' as you connect to anything else on the remote end. Monitoring at ISP routers is a matter of course for semi-pro or professional crackers. Script kiddies hacking routers is a real problem. The infrequency of your connections will help, but it's like leaving your laptop on the bus. You might get it back, you might not. Why take the risk? |

I'm intending to put VMware on the box to allow me to have; -a couple of totally separate database instances going to test ASM concepts - a win2000 'box' to play with remote desktop and perhaps other things so it might be just as well to leave X running (as I've seemingly got it going now). Box is: AMD ATHLON 64 X2 4600+ MSI K9NGM4-F V2 (btw ... don't use this MB this if you're going to use redhat!) 4Gig memory some SATA drives so probably X shouldn't bog it down much ... thanks to everyone for the valuable information :-) See Ya (when bandwidth gets better ;-) Chris Eastwood Photographer, Programmer Motorcyclist and dingbat blog: http://cjeastwd.blogspot.com/ please remove undies for reply |

And for the higher grades of VMware, they really expect you to administer it from that ghods-awful Windows client. > so probably X shouldn't bog it down much ... > > thanks to everyone for the valuable information :-) Why do you want VMware? If you're not running something oddball, like SCO OpenServer which I'm doing right now, Xen works quite well and is built into RHEL and Fedora and plenty of other distributions in para-virtualized and thus more efficient virtualization. And Xen knows how to be run, correctly, from the command line. |

Over here, that would be a very criminal matter indeed. Still I guess in the Land of the Free, only the govt is right? Fred to randomly and casually screw your data over juts because they can. And do pu REALLY think the NSA cant crack an ssh connection if they wan to? Really.. |

And that's an instance where it was revealed. That's right on a major internet fiber trunk, and it went on for years as a matter of ISP policy. Now, given the vagaries of the US Patriot Act and of other nation's security policies, to believe that the traffic is secure at the ISP is ill-founded. And that was insider monitoring at the ISP. The script kiddies are a distinct problem, I'll admit. Given the numerous published vulnerabilities of even good routers, and given the internal cracking and social engineering that can happen to both small and large ISP's, there's just no reason to think any local or remote ISP's routers are safe. None. >>>> and picks up the packets saying 'password' as you connect to >>>> anything else on the remote end. >>> >>> How does he get to monitir any packets at all passing between me and >>> teh remote site? >> >> See above? >> > > So are you saying that te NSA is staffed by script kiddies who routinely > hack into peoplel servers just for the fun of it?

The level of effort required is much higher, and you can't just slap one of the Sandstorm Netintercept boxes into the backbone and reassemble the traffic at whim the way you can with with HTTP and Telnet and RSH. (THey're fascinating devices, at http://www.sandstorm.net/: I've known the company head for years.) |
