I installed ser stable then unstable debs on my 2.2.20 kernel install of unstable debian. Errors: when init.d/ser start: Starting ser: serToo much shared memory demanded: 33554432 Terminated SYSLOG: Mar 5 10:09:19 webserver ser: ERROR: shm_mem_init: could not attach shared memo ry segment: Invalid argument Mar 5 10:09:19 webserver ser: could not initialize shared memory pool, exiting. a friend sent me: scmctl from shmctl(2): Various fields in a struct shmid_ds were shorts under Linux 2.2 and have become longs under Linux 2.4. To take advantage of this, a recompilation under glibc-2.1.91 or later should suffice. (The kernel dis-tinguishes old and new calls by a IPC_64 flag in cmd.) Do I need kernel 2.4? Any hints? Have I missed some documentation? Jaime Hemmett
