That way mail is collected +automatically every time I am connecting to Internet for whatever reason +(I use "diald" to automatically manage my connection). + +However, it did not work. It hung right after the POP3 login. I tracked +this down to the fact that the "pppd" masks a wide range of signals and +this means a time-out does not kick in. As I run the "ip-up" script in +"bash" this masking is inheritied by "fetchmail". + +So, I wrote a silly little "C" program that unmasks all signals and then +runs a command of you choice (in this case fetchmail). This is the code +for that program :- + +#include <stdio.h> +#include <signal.h> + +main(int argc,char * argv[]) +{ +sigset_t set; + + if (argc>1) + { + sigfillset(&set); + sigprocmask(SIG_UNBLOCK,&set,NULL); + system(argv[1]); + } +} + +I call it "allsigs". So, now in my "ip-up" I have the line :- + +allsigs "fetchmail -f /etc/fetahmail" + +Note the quotes as "allsigs" only looks at argv[1]. I guess this +unmasking of all signals could be added into "fetchmail" ? + +James + |
