Longest Open TCP Connection? 37
I thought it would be fun to run this submission fromivan256 who asks: "I was sitting at my desk noticing that i had be telneted between my linux boxes for 16 days, and it got me wondering... What would be the longest continuously open TCP connection? Is it still open?" I'd highly doubt this has actually been recorded, but I'm sure you guys have personal records you wouldn't mind bragging about.

At home I have kept a telnet session open for 2 weeks.... being used about 6 of 24 hours...
Well tis my 2 cents...

Anyway, it was a fun record to set, still got people attempting to duplicate it.

Anyway, I tend to agree with the financial institution notion - they have to keep things open so us people can make our transactions 24/7. Although I have met a few people on IRC who would tend to push that record a bit... hehe.

They open a VC with an host system ant the link
stays open until the ATM goes in maintenace, or
the link hangs up.
ATM normally are using SNA derivatives.
So the VC could be up for days because is taxed
on a packet by packet basis, and even if is only @
4800 bps, is totally sufficient for ATMS.

A Bit of Topic - longest uptime? (Score:1)
I presently have a little work horse of a webserver that I use for some of my original clients. It's been up for 344 days solid now. It would have been up longer, but I had to move it from one room to another less then a year ago.
Is there any sort of record for the longest uptime of a *NIX box?

Before that, we were afraid to reboot the thing because we didn't know if it would come back up right, and it's been up for so long that it's been up longer than I've been with the company. It still had an early version of Debian 2.0 with kernel 2.0.35 =). We were planning to run its UPS down to my car and plug it into a power inverter to get it somewhere without shutting it down, but alas, that isn't neccessary now. ='| =)

Largest amount of data over a TCP connection (Score:1)
Am I right in thinking that in theory a TCP connection could remain open indefinitely but that all TCP connections are limited to a maximum amount of data that they can transfer? Something to do with the fact that a byte count of fixed length is contained in each packet.
This makes the original question rather academic; You can leave a connection open as long as you want but you cannot send any data over it in case you go over the limit...
Re:Largest amount of data over a TCP connection (Score:1)
TCP contains sequence numbers, which are incremented by the number of octets in the packet. This is used as part of the recovery from lost or duplicated packets, but they start at a 'random' number, and it's normal for them to roll over, so you can transmit an infinite number of bytes over the same connection.
There is a time frame where the same sequence number shouldn't be reused, so that gives an limit on the number of bytes which can be transmitted in a single time period (2GB/2 hours seems to ring a bell with me), but if it's slower than that, then you can go on forever.

Well, what I consider a personal record occured about 10 years back. Internet connections abroad were flaky at best, and totally unreliable usually.
It must have been in late 1989 or early 1990 when I held a connection open from Delft, the Netherlands to IscaBBS in Iowa City for 6:52, which was an amazing feat at the time. However, by the end of the session the Americans were up and going to work/school so the routers got loaded and the connection failed.
Ah, those times....
