Port 80 blocked at some ISPs in Singapore?

[Uri Pomerantz]

Hey guys,

I have a bit of a random question - I'm running a website off a server in the US and I'm getting very spotty access (can't access it at all from Hackerspace, only works on certain ISPs). I've read that Starhub blocks port 80 - do you guys know if this is in fact true, and if so, have any of you managed a recommended workaround?

Anyone willing to clear out the water collector or shall I call the
repair guys? Each visit is $45.

suggest the repair guys ... some of the aircons are not cold, i don't know if it's because the remotes are set to 27° or because the refrigerant needs refilling.

Hi all,
 
With regards to my #sniff talk to BCSG6 on how one can steal data straight off the air and with arp based attacks in public networks, someone seems to have taken it one step further this time with cookie based attacks.
 
Details here:
http://codebutler.com/firesheep
 
It's getting easier and easier to exploit and sniff data that is "private" (to you at least) so please be careful when using public wifi spots. They are *NOT* trusted.

Can I suggest we schedule a Music show-and-tell evening at HSG one of these days? You, Ariff, and chordica.com could present. If you guys negotiate an evening that's free on hackerspace.sg/calendar/ we can just do it.
 
Speaking of show-and-tell evenings, tonight's theme will be Biotech. We're expecting a couple of speakers to talk about three or four startups. It'll be crowded so come early, maybe 6:30.
 
I just realized it might be possible to use the stairs as an overflow area, if we set up a video projector on the door, but feed it from a videocamera just upstairs, lol. That way the cigar club can watch the show without interrupting the puffing.

Thanks everyone for the feedback about Yahoo Mail. It's really
useful.
 
And just to square the record on a couple of other points:
 
1, my hackerspace group membership predates my Yahoo gig, so that's
why its a gmail address. That and hackerspace is a google group so the
integration with gmail is better.
2. and also gmail is a great product. No question there.
 
Thanks again for engaging and for those people who expressed interest
in writing about the release. .

By government policy, consumer connections pass through a transparent proxy so sites like http://www.playboy.com/ can be symbolically blocked.

In recent weeks the transparent proxy servers have been flakey.  See

http://www.google.com.sg/search?q=singnet+proxy+404

[Max Cantor]

FYI, Amazon has a datacenter in Singapore, so if you use EC2 you wont have the great firewall of singapore issues.

Also, I doubt that starhub would block port 80 because that would block every website.

whats the address? I can tell you if i can ping it (i'm on starhub)

AFAIK all major isps in SG block incoming 80 and 25 among other ports < 1024 for all their consumer broadband services. This they say is to prevent the spread of viruses and worms. Outgoing access however is unrestricted.

I've had a problem of flaky access to the Internet in general on the
Singtel connections here in SG. I changed my DNS to use the google DNS
(8.8.8.8 & 8.8.8.4) by default and it has helped. I've seen it solve
issues in more than just a few situations.

8.8.8.8 and 8.8.4.4 (not 8.8.8.4)

other public dns:

#neustar dns advantage
nameserver 156.154.70.1
nameserver 156.154.71.1

and 4.2.2.2 may or may not work for you.

there are a few others but they may run ads (everydns) or try to get you
to buy a domain name that can't be resolved.

singnet's dnscache1 is slow and flaky.

Clearly, what the world needs is a VPN company which helps Singapore
users get on an unfiltered, reliable, anonymizable, secure Internet,
without all the trouble of running Tor.

The head end could live in a Singapore colo like SG's EC2, or, for
Hulu and Netflix, in a US colo.

This business would win on execution and distribution. It would scale
excitingly to other countries with national firewalls, so in that
sense Singapore is a great test market for expanding to China and
whatnot.

There would eventually be a P2P element to it, like with Skype or with
BitTorrent, because it would tend to get blocked, and the best way
around that is a pet botnet.

The business model is a subscription to the VPN.

[Chow Loong Jin]

Sounds to me like you just described Tor.

I think he's looking at sub dekasecond latencies and losing less than 95% of packets. No way tor could ever match that.

As it turns out the transparent proxy is present between EC2 & Singapore non-commercial isp users. We've got two clients with live sites hosted in EC2 whose sites were temporarily made completely unusable within Singapore due to issues with the transparent proxies. Indeed I was only able to debug the issue because I was at hackerspaceSG at the time cause we can't reproduce the situation outside Singapore for, what are now, obvious reasons.

I didn't know that it was possible to have crappy DNS performance
until I moved to Singapore. Wireless@SG, singtel and M1 all seem
incabable of running reliable DNS. I have no idea why, though I
imagine there must be a dearth of qualified network engineers here.

Well, singtel has at least one very good network engineer, however they
won't talk about issues like this, so I read that as internal political
problems not unlike the peering spats or architecture failures we
occasionally witness in large ISPs.

Alternatively, one could run their own recursing resolver, I wrote a
wrapper for DJBDNS http://software.haller.ws/djbdns/ so people don't
have to ship data to their provider (or hotspot's) DNS service.

[Kim Yong]

I'm not certain if Carl's grief is caused by flaky DNS but the problem we had looked more like badly configured

transparent proxies.

Even assuming the ports were not blocked I don't really see the
benefits of doing so unless for some reason your bz is SG-centric.

I ran a mobile games portal site back in 05 biz was registered here
but the site was in the US. Perhaps there are some pros to hosting in
SG that I missed.
