 Posted: Sun Sep 12, 2004 6:29 pm Post subject: I am connected to the net, but cannot download files... |
 |
|
I have just installed Gentoo from the LiveCD. I am in a small home network. The LiveCD got the network perfectly, and I could download files and stuff during the install. However, when I rebooted into Gentoo, whilst I am connected to the net (ifconfig gives the right output, I can ping www.google.com successfully) any attempt to download a file (mainly through wget via emerge) fails like this:
| Code: | ayro ~ # emerge vim
Calculating dependencies ...done!
>>> emerge (1 of 3) dev-util/ctags-5.5-r1 to /
>>> Downloading http://gentoo.osuosl.org/distfiles/ctags-5.5.tar.gz
--19:28:55-- http://gentoo.osuosl.org/distfiles/ctags-5.5.tar.gz
=> `/usr/portage/distfiles/ctags-5.5.tar.gz'

Connecting to gentoo.osuosl.org[140.211.166.134]:80... connected.

Where it hangs indefinitely. Here is my ifconfig output:
| Code: | ayro ~ # ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:F1:86:78:79

Thank you very much for any help.
I have previously installed various distro's (Slackware, Debian, Red Hat) on this computer, all of which supported internet out of the box.
If there is anything more I could post that might help, please tell me. |

Well, it sounds like you're connected. Is connecting to gentoo.osuosl.org (via emerge) the only connection problem? Can you browse the web or make pop3/smtp connections?
My first guess is there's a problem with gentoo.osuosl.org (a longshot but a good first guess). If you can connect to other sites try changing your GENTOO_MIRRORS in make.conf to something else like (a known working site):
| Code: | | GENTOO_MIRRORS="http://gentoo.mirrors.pair.com/" |
Let me know if you can browse the web or make a ftp connection. I'll be able to give you some more guesses with that info. =)
What's your connection to the net? Is it modem, dsl/cable, etc. I noticed that your IP address (192.168.123.102) is nonroutable so can I assume that your connected to a router (most likely a full C class subnet and a router address of 192.168.123.1)? |

What's your network layout? Are you going through a router and what is your connection to the Internet (modem, dsl, etc)? Can you successfully ping both news.google.com and 216.239.39.99? What's in /etc/resolv.conf?
Being able to access google.com via lynx and no where else is weird. |

fixed! got the 2.6.5 kernel instead of the 2.6.8 kernel:
from livecd:
emerge =gentoo-dev-sources-2.6.5
compile as normal (although i followed https://forums.gentoo.org/viewtopic.php?t=49036 for coolness) and install!
and it worked! |

Did the kernel 2.6.8 cause this problem?
If I change the kernel to the 2.6.5, can I accomplish this problem? |

Probably another case of this problem.
Send your thanks to the Kernel Devs  |

I'm not up for reading all that  And I'm mildly annoyed that the recent kernels seem to be getting worse, not better (for me) as I've had no problems with <2.6.7 (started at 2.6.5) and plenty with <2.6.6. Kinda like Wine seemed to be doing - everything would only work on non-current versions. It seems better now though. |

| Cool. Although I'm currently happy that I can use ACPI, and don't plan on upgrading my kernel anytime soon. |
