Hi, after upgrading my FreeRADIUS installation to 2.1.6, I tried SIGHUP and got a SIGSEGV back :-/ It didn't happen immediately, but only after the next auth attempt was processed. I have attached my virtual server "Monitoring" - this is the spot in the server where I changed something; the password for this User-Name was changed. Before changing that password and HUPing, auth worked consistently. I attached with gdb to find out what's wrong, the bt is at the end: it failed while xlat'ing User-Name for an sql relay. That's really surprising because I didn't change the User-Name, only the control item Cleartext-Password. Greetings, Stefan Winter ######### virtual server config server Monitoring { authorize { update request { RESTENA-Service-Type := "Nagios-Monitoring" } if ( User-Name == "testuser.monitor@testrealm.lu" ) { update control { Cleartext-Password := "obfuscated" <------------ this is what I changed } } auth_log # users.Nagios pap } authenticate { pap } preacct { } accounting { } session { } post-auth { reply_log sql_relay_main Post-Auth-Type REJECT { reply_log sql_relay_main } } pre-proxy { } post-proxy { } } ########### gdb session with bt Program received signal SIGHUP, Hangup. 0xb7f9a424 in __kernel_vsyscall () (gdb) c Continuing.
