Australian WiMAX pioneer trashes technology as “miserable failure”

wonder if this will be of interest to MCMC, which seems to be pushing wimax as a way to avoid facing the number one problem with Malaysian broadband policy: TMnet’s monopolisation of the copper infrastructure that all Malaysians have paid for.

The same MCMC that has the power to do something about the monopoly amirite?

Apparently, updating to the latest WP release did not help.

I’ve also been having this “problem” for the last couple of days (my last post on 2.2 mysteriously showed up as “Comments off”). After reading the WP site about the security flaws and fixes in 2.3.3 I decided to upgrade, and then posted about it on my blog. Today, I found the “Comments off” on my most recent post AGAIN.

Taking a closer look at both of the affected posts, I found something VERY interesting. Both were edited and a large amount of spam (links) was appended to the end of the post.

I suggest you go to your dashboard and edit your posts to see if you had your posts modified as well. I think it’s quite likely another WP vulnerability that hasn’t been found by the devs yet (or not fixed yet).

At the moment, I’m just removing the spam links from my posts. It appears that only the MOST recent post can be modified, but I haven’t gone through all of my posts yet so I’m not 100% certain.

Somebody broke my unpatched WordPress and closed comments on the most recent post at the same time breaking the site on FireFox. I have now updated -_-

Sadly enough, the ridiculous speeds only lasted 3-4 days total. My connect is back to the good ol’ 448/448 of before. When the largest (TMNet) ISP has a highest advertised consumer broadband speed almost 10 times (4Mbps) that of your current ISP (448kbps/TIMENet) at only double the price (RM138 for 448kbps vs RM198 for 4Mbps), you know that something is wrong somewhere. Either that or maybe it’s time that TIME gets with the times, and stops doing what TMNet is doing by milking every last penny out of whatever monopoly each of them has.

Upgraded? Sure as hell ain’t 448/448 anymore. Possibly a sign of the coming of the almighty NetLynx. Finally, 3 digit download speeds without having to fork out RM1199/mo!!!

 I am afraid of calling to find out if NetLynx is really coming soon in case this is all a mistake and they downgrade me.

Been doing some “work” on getting around these 2 problems in relation to WoW. My initial intent was to connect to my proxy in Jaring via stunnel/dante-sockd… and having iptables reroute the traffic through socat which would disable Nagle’s and set tcp-nodelay to true. For some strange reason (or maybe I just suck at writing iptables rules), I was unable to get iptables to pick up anything to route to socat. So after more research, I decided to take the SS5 SOCKS Server (or SS5) source code any modify it slightly to mangle ALL packets that came through (which should be only WoW traffic unless you are trying to abuse my machine).

Simple workaround:
(1) Grab the SS5 source.
(2) Open SS5Server.c
- #include “netinet/tcp.h”; (Line 26)
- setsockopt(S5SocksSocket, IPPROTO_TCP, TCP_NODELAY, &reuseAddrFlag, sizeof(int)); (Line 197)
(3) ./configure && make && make install
(4) proxify all WoW traffic to ipaddress:port that you configured.

You now have WoW minus Nagle+delayed ACKs. Congratulations.

Recompiling your kernel remotely is bad. Gentoo decided to remove the driver for my eth0 (which wasn’t in use) making my eth1 into eth0… in the process breaking netmount and all related daemons! The new kernel also decided to break apache… so I recompiled that… which broke PHP… which I recompiled… but it depended on ssmtp because qmail was masked. I used superglue to fix everything and now it’s all good.

I would also like to kick Nagle in the nuts… as well as the guy who implemented delayed acks. Thanks.
