Trecker status: "Hostname not found" Is it bug? Please, read carefully


Recommended Posts

My previous post to another old topic was trashed, so...

2 DreadWingKnight : I have read the FAQ and I always use Search! But Signature is funny :)

In my opinion the problem in uTorrent! Why? Because, restart of uTorrent solves the problem but IMHO this is wrong way.

Problem explanation:

I have encountered the same problem as topic writer has. The differences is next.

I run Windows XP and have clean OS without any uTorrent previously. I installed latest uTorrent version 1.8.2 last few weeks.

The problem arises only when I start the computer and after some short period of time (1-2 minutes) connect to the Internet.

Actually, all my torrents from one tracker and all apart of one at the same time become green after short period of time after connection established. Each time this "red icon plague" smile touches only one random torrent. Other torrents work normally in green mode smile.

I'm software developer and highly concerned with a number of network services on any levels even as system administrator. So, I believe that problem concerned with some uTorrent "stuck"/"jam" when it try to resolve hostname without retrying it in future even internet becomes available.

If you give me an email I will send screen shot depicting the bug.

Finally, I have no firewall in OS and my torrent port forwarded properly according to test done by uTorrent.

The difference is enough that it's not the same issue, as the thread was about an old NT version.

You have failed to provide your settings, including the connection limits you have set, as well as any advanced settings you may have changed.

You have failed to disclose what internet security software you have installed on your "clean" system.

I have NO internet security installed on my computer. All settings are default except following:

Queue Settings:

Active torrents upload or download = 15

maximum number of active downloads = 15

Seed while:

Ratio is <350%

No Proxy

Windows standard firewall is ON

Any thing else you want I'll post further.

Ok, according to above issue I have had following things:

# Color of the network status light in µTorrent's status bar (at the bottom of the µTorrent main window)


# What the port checker from the Speed Guide writes


Welcome to the µTorrent Port Checker.

A test will be performed on your computer to check if the specified port is opened.

Checking port 63728 on

OK! Port 63728 is open and accepting connections.

You will be able to receive incoming BitTorrent connections.


# What the Speed Guide shows your settings to be (press Ctrl+G in µTorrent)

Upload limit: 150 Kb/s Upload Slots: 25 Connection per torrent: 125 Connection (Global): 800 Max active torrents: 15

Max active downloads: 15 Current Port: 63728

# What you have net.max_halfopen set to (Preferences > Advanced in µTorrent)

net.max_halfopen =8

# Operating system installed (Windows XP, 2000, ME, 98, 95, NT? Something else?)

Windows XP

# Security software installed (firewall, antivirus, antispyware, antiadware)

Antivirus AVAST, Firewall Windows embeded (standard WinXP firewall)

# Exact router model(s), and exact modem model

No router. UTP cable (RG-45) is plugged directly to net card of computer.

# ISP (Internet Service Provider) being used

ISP internet.beeline.ua (former Svitonline)

# Connection type (DSL, cable, dial-up), and the results obtained from the speed test (when running the Speed Guide), for both download AND upload. Be sure that you aren't using your connection for any other reason besides testing, while testing. That means no downloading, no IMing, no µTorrent running, no browser activity (other than the testing), etc. Additionally, no other computer on your network (if any) should be using the connection. When you select a testing mirror, use the ones that are geographically closest to you.

Yes! Why there is a problem? Explain please. Actually, my connection speed inside UA are 10 Mbit/s and tracker also inside UA. So, I believe the matter not concerned with speed e.g. I uploaded torrent to one peer with speed even over 10 Mbps last week.

Ok. speedtest.net has shown such figures just few minutes ago:

Upload: 26891 Kbps Download: 14857 Kbps ping 9 ms.

"Actually, my connection speed inside UA are 10 Mbit/s and tracker also inside UA."

Are the peers and seeds also inside UA?

Try lowering bt.connect_speed (which defaults to 20 new outgoing connection attempts per second) down to something like 1-4 new outgoing connection attempts.

Actually, 95% of peers are Ukrainian. Others from Italy, Russia,Poland ... All seeds are Ukrainian. I'll set bt.connect_speed = 5 but today all works fine with default values.

New setting of bt.connect_speed = 5 seems help 2nd day I have no problem. Ok. Thanks for anybody.

If something fails I let you know.
