Thanks, I was able to install the packages. However I am stuck with how to make advantage of that. I would expect that the symbols are resolved directly in ProFTPD log: ProFTPD killed (signal 15) ProFTPD 1.3.8 standalone mode SHUTDOWN ProFTPD 1.3.8 (stable) (built Sun Jul 2 2023 10:56:40 UTC) standalone mode STARTUP (localhost[127.0.0.1]): -----BEGIN STACK TRACE----- (localhost[127.0.0.1]): [0] /usr/lib/proftpd/mod_tls.so(+0x19ef5) [0x7f3b60371ef5] (localhost[127.0.0.1]): [1] /usr/lib/proftpd/mod_tls.so(+0x19ef5) [0x7f3b60371ef5] (localhost[127.0.0.1]): [2] /usr/lib/proftpd/mod_tls.so(+0x26a7e) [0x7f3b6037ea7e] (localhost[127.0.0.1]): [3] proftpd: (accepting connections)(modules_session_init+0x57) [0x55950185bbc7] (localhost[127.0.0.1]): [4] proftpd: (accepting connections)(+0x204ad) [0x55950182e4ad] <-- trying to resolve this address (localhost[127.0.0.1]): [5] proftpd: (accepting connections)(+0x20ea1) [0x55950182eea1] (localhost[127.0.0.1]): [6] proftpd: (accepting connections)(main+0x5f8) [0x55950182cb98] (localhost[127.0.0.1]): [7] /lib/x86_64-linux-gnu/libc.so.6(+0x271ca) [0x7f3b606461ca] (localhost[127.0.0.1]): [8] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0x85) [0x7f3b60646285] (localhost[127.0.0.1]): [9] proftpd: (accepting connections)(_start+0x21) [0x55950182d1c1] (localhost[127.0.0.1]): -----END STACK TRACE----- Then I tried the advise from [4]: # addr2line -e /usr/sbin/proftpd 0x55950182e4ad ??:0 and with gdb: # gdb /usr/sbin/proftpd Reading symbols from /usr/sbin/proftpd...
