Olá pessoal, estou enfrentando um problema bem estranho com TFTPd no debian etch, onde ele simplesmente para sem motivo aparente. Eu uso o tftp pois tenho uma rede de Cable Modens que precisam pegar arquivos de modem desse TFTP para efetuar o procedimento de ficar online (implementar o DOCSIS 1.1). Pois bem, o tftpd que instalei é o pacote padrão (apt-get install tftpd), e o mesmo roda no inetd. Por motivos de compatibilidade com um sistema de gerenciamento que tenho, coloquei o repositório do TFTP no /tftpboot.
Segue configuração do inetd e dir para o TFTP: ###Arquivo de configuração ns-mns:/var/log# cat /etc/inetd.conf #:BOOT: TFTP service is provided primarily for booting. Most sites # run this only on machines acting as "boot servers." tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /tftpboot ###Permissões ns-mns:/var/log# ls -la drwxrwxrwx 2 root root 4096 2007-11-24 21:23 tftpboot ns-mns:/tftpboot# ls -la -rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:17 UP0300K -rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:17 UP0600K -rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:23 UP0MDU -rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:19 UP1100K -rwxrwxrwx 1 nobody suporte 4203 2007-06-06 10:35 UP1150K -rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:20 UP1200K -rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:20 UP1300K ns-mns:/var/log# cat /etc/hosts.allow in.tftpd : ALL ###LOGS ns-mns:/var/log# grep tftp daemon.log ### Momentos antes da parada Nov 27 11:41:02 ns-mns in.tftpd[10997]: connect from 10.0.0.1 (10.0.0.1) Nov 27 11:41:02 ns-mns tftpd[10998]: tftpd: trying to get file: UP0100K Nov 27 11:41:02 ns-mns tftpd[10998]: tftpd: serving file from /tftpboot Nov 27 11:41:11 ns-mns in.tftpd[10999]: connect from 10.0.0.1 (10.0.0.1) Nov 27 11:41:11 ns-mns tftpd[11000]: tftpd: trying to get file: UP0150K Nov 27 11:41:11 ns-mns tftpd[11000]: tftpd: serving file from /tftpboot ### Momentos após killall inetd Nov 27 13:54:41 ns-mns in.tftpd[12605]: connect from 10.0.0.1 (10.0.0.1) Nov 27 13:54:41 ns-mns in.tftpd[12607]: connect from 10.0.0.1 (10.0.0.1) Nov 27 13:54:41 ns-mns tftpd[12608]: tftpd: trying to get file: UP0150K Nov 27 13:54:41 ns-mns tftpd[12608]: tftpd: serving file from /tftpboot Nov 27 13:54:41 ns-mns in.tftpd[12609]: connect from 10.0.0.1 (10.0.0.1) Nov 27 13:54:41 ns-mns tftpd[12610]: tftpd: trying to get file: UP3100K Nov 27 13:54:41 ns-mns tftpd[12610]: tftpd: serving file from /tftpboot ###Um dado muito estranho que noto quando o TFTP para (atentar para o valor de Recv-Q): ns-mns:/var/log# netstat -ntlpu Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 109344 0 0.0.0.0:69 0.0.0.0:* 12604/inetd Ps.: Valor normal para o Recv-Q é zero "0". ###Conferindo o manual do netstat ns-mns:/var/log#man netstat Recv-Q The count of bytes not copied by the user program connected to this socket. Ps.: O que pode causar essa situação, dado que entre o Cable Modem e o TFTPd, tem apenas um CMTS fazendo relay de DHCP (o procedimento de pegar o arquivo do TFTP e pegar IP estão íntimamente ligados). ### Tentativa desesperada de parar a instabilidade - Reinstalando o serviço ns-mns:/var/log# grep tftp * | grep -v daemon.log | grep -v syslog dpkg.log.1:2007-11-23 08:32:31 status installed tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:33 remove tftpd 0.17-15 0.17-15 dpkg.log.1:2007-11-23 08:32:33 status half-configured tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status half-installed tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status config-files tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 purge tftpd 0.17-15 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status config-files tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status config-files tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status config-files tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status config-files tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status config-files tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:34 status not-installed tftpd <none> dpkg.log.1:2007-11-23 08:32:49 install tftpd <none> 0.17-15 dpkg.log.1:2007-11-23 08:32:49 status half-installed tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:49 status unpacked tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:49 status unpacked tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:50 status unpacked tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:50 status half-configured tftpd 0.17-15 dpkg.log.1:2007-11-23 08:32:50 status installed tftpd 0.17-15 ###Interfaces e rotas eth1 Link encap:Ethernet HWaddr 00:15:C5:5F:FA:E6 inet addr:10.1.0.2 Bcast:10.1.255.255 Mask:255.255.0.0 inet6 addr: fe80::215:c5ff:fe5f:fae6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:44505679 errors:0 dropped:0 overruns:0 frame:0 TX packets:38978230 errors:0 dropped:0 overruns:0 carrier:0 ns-mns:/var/log# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.0.0 10.1.0.1 255.255.0.0 UG 0 0 0 eth1 Nota: 10.0.0.0/16 - Rede dos CM 10.1.0.1/16 - CMTS 10.1.0.2/16 - TFTP/DHCP -- ------------------------------ Marcello Barreto de Medeiros Network Admin/Programmer +55 84 3231 4617 [Office] +55 84 9914 3254 [Mobile] [EMAIL PROTECTED] [MSN] Linconet Brasil ------------------------------
