Help:

Would somebody from the USA and someone from Europe please run a tracert on their connection to: lazarus.freepascal.org.

I am not able to reach anything lazarus but I can get freepascal.

I want to ask a question in the lazarus list and surf the lazarus forums but I cannot.

Thanks,

Marco

Can you try, if you can access it with a lower MPU ? IIRC a very long time ago, some of the servers or ronnections had an issue / No idea if that is still an issue at all....

yes, i can and i do not normally visit that site...

FWIW: icmp may not be being allowed by the destination site or the router saying that the destination host is unreachable... that last address (below), when searched in google, shows as the first link named "Remote Access Control" but does not respond, AFAICT, to http connections... at least not from my current address...

Well,

I cannot subscribe to the lazarus mailing list and I can not enter the

or www.lazarus.freepascal.org because I can not make an http connection to either.

Just keep timing out.

FYI for list managers...

Cheers all,

marco

Well, you have posted this now several times and several times it has been shown that you are the only one who has such problems. Could you possibly be bothered to start looking at something that could be wrong on YOUR end?:-(

Ralf:

I am very sorry to bother you.

I will not make another request for information on this topic

Each time I started to try to pursue the matter earlier, I got some light responses, but never
was in a position to fully eliminate the problem.

Today, I tried to gather more information using comparative trace routes to solve the problem.

Several other users have been very kind to share their trace routes failing but are still getting through using HTTP.

If this problem follows me to another internet cafe or public wi-fi, I will then try outside of my ISP area
or even leave the region to run a connection test.

All of my computers and tablets here fail, so is likely some silly ISP issue,
like C#//.NET developers at my ISP who filter all pascal traffic!!!

Thank you everyone for your responses and help.

marco

See my other mail,

MTU http://en.wikipedia.org/wiki/Maximum_transmission_unit

Afaik the default used by windows is 1500
http://support.microsoft.com/kb/314496

But somewhere on route is a device that needs them smaller. Normally it wil fragment your packets. But if something, no your PC, or on route from your PC set a flag to disallow this, well then you wont get to the side.

So you need to set yours smaller. eg 1400
You need to google how to do that.

You may be able, if your mail server can connect.

Sent a mail to

You should get a mail, that explains how to subscribe by mail.

Well, that problem, as I see it, is that you just keep looking for it in the wrong place/direction.
As Mark (waldo kitty) already mentioned, a traceroute doesn't necessarily mean anything, the type of data for such scans(ICMP/IGMP) is a lot of times these days filtered along the way.

Today, I tried to gather more information using comparative trace routes to solve the problem.

again, such traceroutes don't mean anything

I am working all over town (Los Angeles, that's a pretty big town!<LOL>), from roughly a dozen different locations, with almost always different ISPs (Verizon, AT&T, Time Warner, Time Warner Business, DSLExtreme, CBeyond,...) , types Internet connection (DSL, digital cable, FiOS, T1/ATM based, wireless broadband) and never had a problem reaching this site.

If you have tested from your own home/office location so far only, look in whatever firewall/router you have in place as the first possible culprit. In an earlier post you showed the start of your traceroute,

1 6 ms 1 ms <1 ms 192.168.7.1 2 1 ms <1 ms <1 ms 192.168.6.1 3 35 ms 24 ms 16 ms cable-mac1.faptnyal-ar4003.nyroc.rr.com [66.66.72.1]

which indicates that you double NAT'ed before you hit the first router in the Roadrunner/TWC infrastructure in Rochester, NY. That makes two local devices that can possibly interfering. Unless you start looking into those, at the very least to eliminate them as the source for your problem, you can compare other people's traceroutes all you want, you still will be looking at the wrong end...

Yes.

(rearranged, to Marco: pls avoid top-posting... unless you have a good reason)

Hi Marco,

usually a site like http://www.downforeveryoneorjustme.com/ helps (short url : http://isup.me )

(btw http://www.downforeveryoneorjustme.com/lazarus.freepascal.org says site is up as of 7/4/14 8:40 BST/London time).

That is an excellent link.
This is a great community.
Thank you all for sound advice.

I will also stop top posting, per lukas request.
