That way mail is collected 35automatically every time I am connecting to Internet for whatever reason 36(I use "diald" to automatically manage my connection). 37 38However, it did not work. It hung right after the POP3 login. I tracked 39this down to the fact that the "pppd" masks a wide range of signals and 40this means a time-out does not kick in. As I run the "ip-up" script in 41"bash" this masking is inheritied by "fetchmail". 42 43So, I wrote a silly little "C" program that unmasks all signals and then 44runs a command of you choice (in this case fetchmail). This is the code 45for that program :- 46 47#include <stdio.h> 48#include <signal.h> 49 50main(int argc,char * argv[]) 51{ 52sigset_t set; 53 54 if (argc>1) 55 { 56 sigfillset(&set); 57 sigprocmask(SIG_UNBLOCK,&set,NULL); 58 system(argv[1]); 59 } 60} 61 62I call it "allsigs". So, now in my "ip-up" I have the line :- 63 64allsigs "fetchmail -f /etc/fetahmail" 65 66Note the quotes as "allsigs" only looks at argv[1]. I guess this 67unmasking of all signals could be added into "fetchmail" ? 68 69James 70 71
