debian 升級後eclipse不能調試

debian 升級後不能eclipse不能調試,出現如下的提示:

 

ERROR: transport error 202: connect failed: Connection refused
     ERROR: JDWP Transport dt_socket failed to initialize,
     TRANSPORT_INIT(510)
     JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports
     initialized [../../../src/share/back/debugInit.c:690]
     FATAL ERROR in native method: JDWP No transports initialized,
     jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

 

我換來jdk,換了eclipse 還是出錯,最好上網查到一個到期的網頁才知道是debian設定的問題,debian 及eclipse的bug list都有,解決方案如下:

1.edit /etc/sysctl.d/bindv6only.conf and  net.ipv6.bindv6only行的1改成0
2.sudo invoke-rc.d procps restart

 

附:

found the reason/fix on this post:

The problem was caused by a pretty unbelievable thing introduced in
     debian. Found out that java was no longer able to do any sort of
     network connections anymore. Even connections to localhost failed...
 
    Someone decided to introduce a ipv6-only switch in netbase via
     /etc/sysctl.d/bindv6only.conf. While this may or may not be a
     usefull default behaviour for the general the result is that java is
     no longer able to do networking at all.
 
    So to solve it you have to edit /etc/sysctl.d/bindv6only.conf and
     change the value of net.ipv6.bindv6only from "1" to "0". Then do a
     "sudo invoke-rc.d procps restart". After that, java has networking
     again.
