저는 Debian Jessie 8.2를 사용하고 있으며 3G 연결을 사용하고 있습니다.화웨이 MU709 미니 PCIe.
3G 연결은 잘 작동하지만 24시간이 지나면 연결이 끊어지고 다시 연결할 수 없습니다. 컴퓨터를 다시 시작하면 연결이 다시 작동합니다.
내 생각엔 내 ISP가 24시간 후에 나에게 새 IP 주소를 제공했지만 내 시스템이 이를 처리할 수 없었던 것 같습니다.
다시 시작하지 않고 3G 연결을 다시 연결하는 방법은 무엇입니까?
다음 명령을 시도했습니다.
sudo service network-manager restart
그리고:
dhclient -r eth0
dhclient eth0
편집 1:
journalctl결과에 대한 내 연결 이름을 grep합니다( SFR).

보시 sept 22 at time 17:18다시피 컴퓨터가 부팅되는 순간입니다. 약 24시간이 지나면 재접속이 불가능해집니다.
또한 명령을 실행하는 스크립트가 있다는 점을 언급해야 합니다.
sudo service network-manager restart
컴퓨터가 서버에 대해 ping을 수행할 수 없으면 연결이 끊어집니다.
편집 2:journalctl시스템이 다시 연결을 시도할 때 추가 정보를 추가합니다.

마지막 수정:
내가 찾은 유일한 해결책은 MU709 모뎀을 VIA EMIO-2550으로 변경하는 것이었습니다. VIA에 연결 문제가 없습니다.

GSM 연결에서 어떤 인터페이스를 사용하고 있는지 확실합니까 eth0? 대부분의 경우 이것이 사실 ppp0이거나 최신 MBIM 프로토콜이 사용됩니다 wwan0. 모바일 광대역과의 인터페이스는 매우 드뭅니다.usb0eth0
귀하의 GMS 카드는 이 /dev/ttyUSB0인터페이스를 사용하여 실제 모바일 광대역 네트워크에 연결하고 pppd이 인터페이스를 통해 eth0개인 DHCP 네트워크에 대한 연결을 전달하는 것으로 보입니다. 169.254.xx IP 범위는 간단한 DHCP 연결을 제공하는 데 사용되는 링크-로컬 주소입니다.
따라서 NetworkManager가 pppd 연결을 설정할 수 없으면 모바일 광대역을 사용할 수 없습니다.
내 경험에 따르면 ISP는 연결된 경우 IP 주소를 절대 변경하지 않으며 적어도 모바일 광대역의 경우 다시 연결할 때마다 항상 다른 IP 주소를 제공합니다.
지금 무슨 일이 일어나고 있는 걸까요(다시 말하지만, 제 개인적인 경험입니다) 모뎀안녕, 미니 PCIe 카드이므로 간단히 꽂았다가 뺄 수 없습니다. 여기는 구식이야존재하다명령이 유용합니다.
즐겨 사용하는 직렬 연결 애플리케이션으로 포트를 연결해 보십시오 /dev/ttyUSB0. Putty저는 원본을 사용하고 있어요.minicomcutecomcubusybox microcombusybox microcom
nmcli radio wwan off
sudo busybox microcom -t 10000 /dev/ttyUSB0
여기에 AT 명령을 입력하세요.
ATZ
AT+CFUN=0
10초 동안 기다립니다. 그리고 다시 연결하세요.
sudo busybox microcom -t 10000 /dev/ttyUSB0
AT+CFUN=1
이제 종료하고 NetworkManager 애플릿을 통해 다시 연결해 보십시오.
모바일 광대역 연결이 활성화되면 다음 명령을 실행하고 질문을 업데이트하십시오.
ps ax | grep 'pppd' | grep -v 'grep'
귀하의 GSM 카드는 훌륭하고 많은 고급 기능을 갖추고 있지만 안타깝게도 제대로 작동하지 않습니다.
답변2
NetworkManager는 3G 모뎀 처리에 관여하지만 작은 부분일 뿐입니다. 모뎀과 통신하는 실제 프로그램은 ModemManager라고 합니다. 내 노트북도 가끔 연결이 끊어지는 것을 발견했습니다.
systemctl restart ModemManager
충분한.
답변3
로그 출력에서는 journalctl이러한 일이 발생하는 원인이 무엇인지 명확하게 밝히지 않습니다. 다음을 순서대로 수행하는 것이 좋습니다.
1). 이 경우 인터페이스를 수동으로 설정해 보십시오.
ifconfig eth0 up
또는 ifconfig아직 설치하지 않은 경우 다음 명령을 사용하여 설치할 수 있습니다 ip.
ip link set dev eth0 up
2). 그래도 도움이 되지 않으면 /var/log/syslog관련 메시지를 확인하세요.
경험을 바탕으로 추측해야 한다면 이는 모뎀 자체와 관련된 구성 문제입니다. NetworkManager 구성 파일 자체를 게시하고 여기에 포함될 수 있는 민감한 정보를 제거할 수 있습니까?
