Hi, I think there is still a bug in the trunk: Line 50 in XrdSecsssKT.cc: if ((randFD = open("/dev/random", O_RDONLY)) < 0 should probably be if ((randFD = open(devRand, O_RDONLY)) < 0 The implementation with /dev/random does not work well on machines without keyboards. Normally we have very low entropy on this machines and I long hangups before authentications because there are no random numbers available. Could be the default maybe /dev/urandom and /dev/random only as a config option? Cheers Andreas.
