wicd - 啟動後沒有連接，必須手動重新啟動？

  • March 21, 2012

我正在使用版本 1.7.1_pre20120127 和 python 2.7.2：

[U] net-misc/wicd
    Available versions:  1.7.0 (~)1.7.0-r1 1.7.1_beta2-r4 (~)1.7.1_pre20111210-r1 1.7.1_pre20120127 (~)1.7.1_pre20120127-r1 (~)1.7.1 (~)1.7.1-r1 {X ambiance +gtk ioctl libnotify mac4lin ncurses nls +pm-utils}
    Installed versions:  1.7.1_pre20120127(01:42:42 PM 02/29/2012)(X gtk libnotify ncurses nls pm-utils -ioctl -mac4lin)
    Homepage:            http://wicd.sourceforge.net/
    Description:         A lightweight wired and wireless network manager for Linux

如果我將 wicd 添加到defaults執行級別，它總是在啟動後詢問 root 密碼。但是如果我將它添加到boot執行級別，則沒有連接（有線和無線）：

您會看到“權限被拒絕”錯誤，因為我標記/etc/resolv.conf為不可變。注意最後一行。

這是手動重新啟動 wicd 時的日誌：

這個問題類似於：https://bbs.archlinux.org/viewtopic.php?id=121589，但是硬體時鐘是正確的，我找不到任何與 in 相關的ntpdate腳本/etc/wicd/scripts/postconnect/。

有任何想法嗎？

更新：2012 年 3 月 2 日星期五 16:36:12 ICT

dhcpcd並且wpa_supplicant已經從default執行級別中刪除：

gentoo ~ # rc-update -v show | grep dhcpcd
              dhcpcd |                                 
gentoo ~ # rc-update -v show | grep wpa
      wpa_supplicant |

net.eth0被刪除：

gentoo ~ # rc-update -v show | grep eth0
            net.eth0 |

回复凱爾瓊斯：

要檢查您的配置是否與硬體時鐘的設置不一致，請執行

date; /sbin/hwclock --show

# date; hwclock --show

clock_systohc="NO"
clock_hctosys="NO"
clock_args=""

今天，日誌顯示“成功”但wicd無法連接到任何網路：

Putting interface up...

dhcpcd[5063]: forked to background, child pid 5094

wicd-gtk顯示“未連接”並且eth0沒有 IP：

eth0      Link encap:Ethernet  HWaddr 00:13:a9:4f:84:44  
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

         RX bytes:205470 (200.6 KiB)  TX bytes:34017 (33.2 KiB)
         Interrupt:16

問題解決了！罪魁禍首是……hwclock。

正如我上面所說，下面是配置。對於我的時鐘：

clock="UTC"
clock_systohc="NO"
clock_hctosys="NO"
clock_args=""

但我有這個（愚蠢的）行/etc/local.d/baselayout1.start：

hwclock --hctosys

使用此配置，這是啟動後的日期時間：

gentoo ~ # hwclock 
Wed 21 Mar 2012 10:29:57 AM ICT  -0.134053 seconds
gentoo ~ # hwclock --utc
Wed 21 Mar 2012 05:30:01 PM ICT  -0.928500 seconds
gentoo ~ # date
Wed Mar 21 10:30:03 ICT 2012
gentoo ~ # date --utc
Wed Mar 21 03:30:06 UTC 2012

hwclock和date輸出是對的，比hwclock --utc晚date --utc7小時，比早7小時。

刪除此行hwclock --hctosys並更改/etc/local.d/baselayout1.start並clock_systohc解決clock_hctosys問題："YES"``/etc/conf.d/hwclock

gentoo ~ # hwclock 
Wed 21 Mar 2012 03:33:43 AM ICT  -0.404693 seconds
gentoo ~ # hwclock --utc
Wed 21 Mar 2012 10:33:46 AM ICT  -0.418345 seconds
gentoo ~ # date
Wed Mar 21 10:33:48 ICT 2012
gentoo ~ # date --utc
Wed Mar 21 03:33:54 UTC 2012

您的硬體時鐘設置的時區（UTC 或您的本地時區）與您的 Linux 系統配置認為它設置的時區之間很可能存在分歧。如果它們不同，hwclock將在系統初始化期間錯誤地設置系統時鐘，稍後 NTP 守護程序將在發現您的系統時間偏離您的本地時區與 UTC 的小時數時修復系統時鐘。

要檢查您的配置是否與硬體時鐘的設置不一致，請執行

date; /sbin/hwclock --show

如果顯示的時間相隔數小時，則您的配置與硬體時鐘設置不匹配。我不熟悉 Gentoo 配置的工作原理，但在其他一些 Linux 發行版上，您可以編輯 /etc/sysconfig/clock 並設置UTC=true或UTC=false取決於您的硬體時鐘是否設置為 UTC。我認為您的硬體時鐘設置為您當地的時區，所以您需要UTC=false.
