General questions about debugging and operation
by Ralf Hildebrandt 29 Jul '17

29 Jul '17

Hi! I'm using yesterday's git checkout. Routing of the requests to our own RADIUS and germany's DFN Radius server is working OK! Questions: ========== * Currently, radsecproxy is running as root. Is that necessary? It's not binding to any privileged ports. * Can radsecproxy run chrooted? * during our 2 days of operation, it crashed three times - which is why I compiled the lasted version manually instead of using Ubuntu's packages: Jul 5 14:51:43 radius-ext kernel: [5611.904760] radsecproxy[2710]: segfault at d8 ip 00007f0717424518 sp 00007f07183e4e20 error 6 in libc-2.23.so[7f071733c000+1c0000] Jul 6 09:28:46 radius-ext kernel: [72633.333687] radsecproxy[21034]: segfault at d8 ip 00007f5c647d8518 sp 00007f5c65798e30 error 6 in libc-2.23.so[7f5c646f0000+1c0000] Jul 6 12:15:19 radius-ext kernel: [82626.748886] radsecproxy[120425]: segfault at d8 ip 00007f1267ec5518 sp 00007f1268e3bd50 error 6 in libc-2.23.so[7f1267ddd000+1c0000] How do I debug this; is it dumping cores even when running as root? -- Ralf Hildebrandt Charite Universitätsmedizin Berlin ralf.hildebrandt(a)charite.de Campus Benjamin Franklin https://www.charite.de Hindenburgdamm 30, 12203 Berlin Geschäftsbereich IT, Abt.
