Hello list, Recently I compiled ser 0.9.0 with mysql acc, and ser seems working ok, except I get a warning message twice when I run SER: fix_socket_list: could not rev. resolve 192.168.0.100 (my SER box's internal ip) Output: Listening on udp: 192.168.0.100 [192.168.0.100]:5060 tdp: 192.168.0.100 [192.168.0.100]:5060 Aliases: *:(its WAN ip address):* *:ser1.mydomain.com:* etc And I port forwarded tcp and udp5060 to my SER box. Why do I get this warning?Is it simply because my SER box is behind NAT? Back to my main question: I got an error 400; check if you use aliases in SER message when I tried "serctl add newusername newpasswd email(a)mail.com"quot;. I exported my SIP_DOMAIN to be ser1.mydomain.com and also updated the serctl script with the appropriate db domain and access username and password. Here is the global definition section of my ser.cfg: debug=3 fork=yes listen=192.168.0.100 alias=ser1.mydomain.com alias=(my WAN ip) port=5060 children=4 fifo="/tmp/ser_fifo" fifo_db_url="mysql://username:pass@mysqldomain.com/ser" ... Thank you in advance.
