O tftpd-hpa não inicia após a atualização

Eu tenho o tftpd-hpa instalado (Ubuntu 16.04 LTS). Recentemente, talvez depois de obter algumas atualizações (ou desinstalar algum aplicativo com dependências vaste) o tftpd-hpa não inicia mais. As configurações do tftpd-hpa são: 

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure --create"

O diretório raiz padrão é /var/lib/tftpboot . Saída dos comandos systemctl status tftpd-hpa.service e journalctl -xe : 

testlab@Amtek:~$ systemctl status tftpd-hpa.service

Combinando as duas partes da informação:

Recently, after some updates received

E o seguinte erro:

Apr 18 01:47:32 Amtek in.tftpd[4777]: cannot bind to local IPv4 socket: Address already in use

Parece que o problema é que a porta tftp (69) já está em uso, quando você inicia o servidor tftp. Isso pode ser devido a um novo programa que foi instalado / atualizado recentemente.

A execução do comando a seguir ajudará você a descobrir qual processo está usando a porta tftp (69) em sua máquina: 

netstat -lnp | grep 69

netstat man

-l, --listening Show only listening sockets. (These are omitted by default.)

--numeric , -n Show numerical addresses instead of trying to determine symbolic host, port or user names.

-p, --program Show the PID and name of the program to which each socket belongs.

Note: The | grep 69 filter the result and will show only the lines which holds 69 in them

Editar:

Conforme você adicionou à sua pergunta, o resultado de netstat -lnp mostra que agora inetd está sendo executado no udp / port 69, é possível que ele execute o cliente tftp como parte de inetd , portanto você não pode executar tftpd-hpa nessa porta.

Note: Please check if tftpd is running, and if it is good enough you can avoid using tftpd-hpa

Você tem duas opções:

  • Mover tftp server para usar porta diferente Isso pode ser feito alterando a seguinte linha que define tftp na porta 69:

    TFTP_ADDRESS=": 69"

    Para usar outra porta, por exemplo 6900:

    TFTP_ADDRESS=": 6900"

Nota: O uso desta solução exigirá que tftp-client use o novo número de porta

  • Pare inetd do uso de udp / 69 Você pode verificar se o tftp configuration file existe na pasta inetd , procurar por um arquivo em um nome como:

    /etc/xinetd.d/tftp

ou 

 /etc/inetd.d/tftp
