Доброго времени суток,
Имеем: последний Сизиф, ядро 2.4.20-alt7-smp.
Пытаюсь натравить strace на процесс smtpd-sasl:
#ps axu|grep sasl
postfix 14135 0.2 0.2 7964 2144 ? S 01:31 0:00 [smtpd-sasl]
#starce -p 14135
trace: ptrace(PTRACE_SYSCALL, ...): Operation not permitted
#ps aux|grep sasl
postfix 14135 0.0 0.2 7964 2148 ? T 01:31 0:00 [smtpd-sasl]
процесс smtpd-sasl останавливается и висит до отправки ему
сигнала SIGCONT:
#kill -CONT 14135
#ps aux|grep sasl
postfix 14135 0.0 0.2 7964 2148 ? S 01:31 0:00 [smtpd-sasl]
после этого - все нормально, но strace сделать так и не удается.
Ситуация воспроизводится на любых процессах, сменивших UID
во время исполнения.
Как с этим бороться, т.е. как же все-таки добиться от strace того,
чего хочется? %)
