ANZ Bank Data Centre is located in Melbourne, Australia and I think you are in New Hampshire US or you ISP - Dynamic Network Services, Inc. - is located there. Don't ever worry about any institution where the users predominately site behind a 3270 or derivation emulation screen as this means they are using a Mainframe with secure SNA comms. The term silly protocol change is not valid, its hard, dam hard and that why we need another mainframe to not only convert the protocol but to make the transfer transparent and remove TCP's ability to escalate authority. This aspect is O/S dependant and the Mainframe that performs the change runs VTAM and its as safe as a house. John, yes there is online banking as we both know, However there is a dirty great big IBM 3172 sitting between all main internal SNA architecture that is used by every branch ANY TCP source must pass through the 3172 is to convert its native SNA at the Data Centre. This provides connectivity between the protocols. The 3172 runs a MVS/C interface initially, but has been replaced by VTAM. The 3172's many of which are still operational have been replaced by new Models as support from IBM halted in 1988. They still remain the workhorse for transparent TCP/IP/SNA protocol.

Re: [opensuse] RE:Back Door Prosiak client connection in Linux
Dear James, Yes we both know that improvements have been made and you have indicate a great knowledge of the groups of protocols we know as TCP/IP. I agree we have made inroads since the early inception of the protocols - however you understand that - Particularly Windows relies on the ability we have within the protocol for escalation of authority which we can never fundamentally change as we are dependant on this at the Client PC - The main issue in this article is the ability to escalate authority - Yes I agree with you HTTP/SSL where we can dump 'r' commands. With your obvious knowledge I think you will agree that our only escape from the innate issues about the protocol are solved with TCP/IP V6. You know as well as I do that the world root servers run TCP/IP V6. The issues of escalation have been dealt with in V6 - however would wide adoption of V6 at the client end will take decades. WE with Suse Linux attribute our security because it runs on V6. There is mass translation in the product as you well know and if you run your own DNS server, any enquiry made to a another DNS server; if it can communicate by V6 IT WILL. This is very easy to see when you look at a real time log of the DNS server created in a Suse Linux platform. Its not had to log all activity into the system log and view it. Thank you for bringing sensible and constructive conversation about comms issues. It is nice to be able to discuss comms with another who has an understanding of its role. Have a great Day James Scott ;-) James Knott wrote: I'm not quite sure where to start, but there are a lot of errors in your message. Registration Account wrote: TCP/IP I am sorry will go down in history as the most insecure and worst collection of protocols ever conceived. Some protocols aren't that great. Others are fine and some have been fixed. The origins of TCP/IP are well know as it was created by the US Government and bell Labs in 1979. It was to provide a vehicle that could network US Military missile silos and internal comms. It was developed on behalf of DARPA, a defence dept research organization as a result of investigations into robust networks that could survive a fair amount of damage. It was initially used to link the military and research institutions, such as universities. It was abandoned because the protocol was subject to potential abuse and not considered a secure comms protocol. I think you need to have a look at the beginnings of TCP/IP and realise why is was dumped. http://64.233.167.104/search?q=cache:CCf8DOW0v1QJ:csrc.nist.gov/publications/secpubs/ipext.ps+tcp/IP+fails+bell+labshl=enct=clnkcd=5gl=auclient=firefox-a That article was written 14 years ago. A lot has happened since then. Some of the things it discusses have been replaced by more secure methods, such as the r commands with secure shell etc. But so much money was spent on development, Microsoft saw an instant market for its use. TCP/IP because of its flexibility provided the vehicle for the world wide web which was essentially meant to transfer information. As the web grew the issues of innate design flaws in the protocol needed patching up to provide HTTP/SSL. MS initially resisted it and Windows 95 was originally planned to not use it. It was only after many other companies started adopting it, that MS did as well. For example, OS/2 had it included with Warp 3, which was released in 1994, more than a year before Windows 95. Novell was also starting to work with it then too. It is important to realise that the TCP/IP fundamentally failed as a secure comms transport because of the ability for an intermediate intercept being not only able to join the a data stream from A - B, but more over was capable of permitting a third party to escalate their own authority, despite not being a part of the communications from A - B. In Australia we will NOT use TCP/IP for government or direct Banking requirements. Thats why do don't worry about massive amounts of data being hijacked.

We don't have Data high jacking in this country as a result. With respect to token ring - Do not dismiss the topology as it is capable of carrying many transport layers. The issues of speed that have been tanked about are wrong. Token ring submits 1 token at a time - It does not use multiple tokens. The topology is dependant on the speed it takes from 1 token to pass the logical LAN with many Lans coming from different routers (not MAU's). Speed issues have improved out of sight

Also, years ago, token ring had many performance advantages over the ethernet of the day. For example, with ethernet, collisions had a significant limiting effect on usable bandwidth. Token rings are also deterministic, which means you knew the maximum time for the data to be transferred. This is important in some critical situations.

Actually, TCP, not including IP predates token ring by almost a decade. The oldest computer network technology that I've worked on is the TDM loops used with the Collins line of computers. These computers were MIL spec versions of IBM gear and were networked back in the mid '60. The networks used time slots, instead of packets to share the cable. The original TDM system ran at 2 Mb/s and the later TDX loop was 8 Mb/s. The network was connected in a ring or loop. The network used relays to connect devices, such as CPU, tape and disk drives, card readers etc. to the loop. In TDX systems, high speed devices, such as the CPU, tape and disk drives were connected directly to the TDX loop. Lower speed devices were connected to the TDM loop, which in turn, connected to the TDX loop via an interface box. There was also a loop sync box, which maintained loop syncronization. Here's a picture of what is in fact the 8401 model of the Collins system, even though it says 8500C. The CN referred to in the picture is for Canadian National Railways. I started my career working for their telecommunications division about 35 years ago and work on the 8500C, though occasionally did minor work on the 8500B, along with many other mini-computer types.

The sad part is they invented it while the unix world was happily running TCP/IP. Token ring was invented in 1960, tcp/ip in the 70's. Actually, TCP, not including IP predates token ring by almost a decade. The oldest computer network technology that I've worked on is the TDM loops used with the Collins line of computers. These computers were MIL spec versions of IBM gear and were networked back in the mid '60. The networks used time slots, instead of packets to share the cable. The original TDM system ran at 2 Mb/s and the later TDX loop was 8 Mb/s. The network was connected in a ring or loop. The network used relays to connect devices, such as CPU, tape and disk drives, card readers etc. to the loop. In TDX systems, high speed devices, such as the CPU, tape and disk drives were connected directly to the TDX loop. Lower speed devices were connected to the TDM loop, which in turn, connected to the TDX loop via an interface box. There was also a loop sync box, which maintained loop syncronization. Here's a picture of what is in fact the 8401 model of the Collins system, even though it says 8500C. The CN referred to in the picture is for Canadian National Railways. I started my career working for their telecommunications division about 35 years ago and work on the 8500C, though occasionally did minor work on the 8500B, along with many other mini-computer types.

Re: [opensuse] RE:Back Door Prosiak client connection in Linux
TCP/IP I am sorry will go down in history as the most insecure and worst collection of protocols ever conceived. The origins of TCP/IP are well know as it was created by the US Government and bell Labs in 1979. It was to provide a vehicle that could network US Military missile silos and internal comms. It was abandoned because the protocol was subject to potential abuse and not considered a secure comms protocol. I think you need to have a look at the beginnings of TCP/IP and realise why is was dumped. http://64.233.167.104/search?q=cache:CCf8DOW0v1QJ:csrc.nist.gov/publications/secpubs/ipext.ps+tcp/IP+fails+bell+labshl=enct=clnkcd=5gl=auclient=firefox-a But so much money was spent on development, Microsoft saw an instant market for its use. TCP/IP because of its flexibility provided the vehicle for the world wide web which was essentially meant to transfer information. As the web grew the issues of innate design flaws in the protocol needed patching up to provide HTTP/SSL. It is important to realise that the TCP/IP fundamentally failed as a secure comms transport because of the ability for an intermediate intercept being not only able to join the a data stream from A - B, but more over was capable of permitting a third party to escalate their own authority, despite not being a part of the communications from A - B. In Australia we will NOT use TCP/IP for government or direct Banking requirements. Thats why do don't worry about massive amounts of data being hijacked. You will recall the latest computer fraud in the USA where a merchant lost over 200.000 customer credit details etc. http://www.merchantaccountblog.com/archives/268 http://www.google.com.au/search?q=data+loss++in+us+merchant+in+2007ie=utf-8oe=utf-8aq=trls=org.mozilla:en-GB:officialclient=firefox-a ALL government Mainframes and law enforcement use SNA here and we are not about to dup it in the short term. We don't have Data high jacking in this country as a result. With respect to token ring - Do not dismiss the topology as it is capable of carrying many transport layers. The issues of speed that have been tanked about are wrong. Token ring submits 1 token at a time - It does not use multiple tokens. The topology is dependant on the speed it takes from 1 token to pass the logical LAN with many Lans coming from different routers (not MAU's). Speed issues have improved out of sight since original design. The major issue early on was that the cable that token ring requires is as expensive as hell, Unshielded twisted pair is a cheap as chips. http://www.google.com.au/search?q=token+ring+multiple+protocolsie=utf-8oe=utf-8aq=trls=org.mozilla:en-GB:officialclient=firefox-a Scott ;-) G T Smith wrote: John Andersen wrote: On Wednesday 13 June 2007, Registration Account wrote: and IBM invented token ring Another roaring success story.

I'm not quite sure where to start, but there are a lot of errors in your message.

Others are fine and some have been fixed. The origins of TCP/IP are well know as it was created by the US Government and bell Labs in 1979. It was to provide a vehicle that could network US Military missile silos and internal comms. It was developed on behalf of DARPA, a defence dept research organization as a result of investigations into robust networks that could survive a fair amount of damage. It was initially used to link the military and research institutions, such as universities.

A lot has happened since then.

TCP/IP because of its flexibility provided the vehicle for the world wide web which was essentially meant to transfer information. As the web grew the issues of innate design flaws in the protocol needed patching up to provide HTTP/SSL. MS initially resisted it and Windows 95 was originally planned to not use it. It was only after many other companies started adopting it, that MS did as well. For example, OS/2 had it included with Warp 3, which was released in 1994, more than a year before Windows 95. Novell was also starting to work with it then too.

Re: [opensuse] RE:Back Door Prosiak client connection in Linux
Thanks randall, I should have worked that out for myself. I was browsing and downloading files from dell.com for a troublesome dell PC (No surprises there, as I have never found 1 dell PC that comes close to being 100% IBM compatible - due to their amazing number of BIOS/Chipboard drivers which are needed) and I received a latter response, indicating the Network had been compromised( immediate Internet connect to network shut-down) from an IP in .TW, the whole range I have now placed on reject RTS to any packet from 143.166.0.0/16) I had completely forgotten my 1 Windows XP running PC on the network. Its the last one to await conversion due to internal issues. ALL staff have had ALL user passwords changed and the Windows XP was found with a little bit of nice spyware it is the very nasty and hard to get rid of 'DSO Exploit' I have changed the Windows XP user to a limited user until I can change the O/S Regards Scott P.S So do any other Windows users think they are safe??? My Network is a secure as a Bank and this hacker was still able to compromise 1 windows system.
