Note that you can bind to IPv4 and IPv6 at the same time. You can do this with listen [::]:80; syntax. I also had the problem of two things binding to port 80 on the same address family and it was because I had two conflicting server statements. – Azendale Mar 1 '13 at 4:40

This PC has two Ethernet cards, one connecting to my "Outer" network and on to the Internet, and one connecting to my "Inner" network, so I have BiglyBT set up to only bind to the static IPv4 and IPv6 addresses on the "Outer" Ethernet port. Everything seems to be working properly on UDP port 17273. TCP/UDP: Socket bind failed on local address [undef]:443: Permission denied Thu Nov 5 08:42:14 2009 Exiting Guys have solution please let me Know. Thanks, Re: [Openvpn-users] Socket bind failed on local address [undef]:443: Permission denied Oct 02, 2014 · In UNIX/LINUX, assigned port 1024 and below require root privilege. Either you run graylog2 as root (not recommended) or follow below workaround. Solution. 1. Create new Syslog UDP inputs and listen to any port (ex: 5514). 2. Manipulate traffic using iptable: iptables -t nat -A PREROUTING -i eth0 -p udp -m udp --dport 514 -j REDIRECT --to-ports Oct 10, 2018 · This check udp port article will talk about the User Datagram Protocol, what is used for and the tool to use it. User Datagram Protocol (UDP) is like a send and forget protocol. To check if the UDP port is open or not, you should receive a response from the port.

However, ther are a couple of things that you need to be aware of. The snmpdx daemon is started with /etc/rc3.d/S76snmpdx script. There is a another script /etc/rc3.d/S77snmpXdmid which requires to bind to snmpdx at port 161. If you force the snmpdx to use port 8161 at startup, then snmpXdmid script will fail.

TCP/UDP: Socket bind failed on local address [undef]: Address already in use You've got something else running on that combination of protocol/port. You can take a look what it is by doing netstat -nlp | grep 1234 (change port number accordingly) and kill that process or move that to another port.

2020-01-03T09:00:51-0500 [DuoForwardServer (UDP)] Received new request id 0 from ('172.16.169.150', 62132)!!!!! Next we list the RADIUS ID (0) contained in the raw RADIUS request. This ID will follow the request throughout the entire process. We also list the source port that originating appliance/application used to send the request (62132).

This bind failure problem is usually caused when UDP port 161 is reserved for the wrong job name. It will cause the SNMP agent to fail to initialize. If SNMP issues EZZ6236I or EDC5111I , you need to check your port reservations in the TCPIP profile for SNMP.
