You have an SELinux profile that doesn’t allow Unbound to use same UDP port range that Unbound is configured to use. At one point, the CentOS Unbound rpm had a SELinux profile inconsistent with the Unbound. Or you changed the Unbound config, and didn’t update SELInux. </div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Tom</div><div class=""><br class=""></div><div><br class=""><blockquote type="cite" class=""><div class="">On Jun 16, 2021, at 10:56 AM, Modster, Anthony via Unbound-users <<a href="mailto:unbound-users@lists.nlnetlabs.nl" class="">unbound-users@lists.nlnetlabs.nl</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta charset="UTF-8" class=""><div class="WordSection1" style="page: WordSection1; caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><p class="Default" style="margin: 0in 0in 8pt; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10);">Hello<o:p class=""></o:p></p><p class="Default" style="margin: 0in 0in 8pt; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10);">What causes the error to bind socket ?<o:p class=""></o:p></p><p class="Default" style="margin: 0in 0in 8pt; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10);">We have seen these errors when configured for “unbound resolver” or “unbound forwarding” modes.<o:p class=""></o:p></p><p class="Default" style="margin: 0in 0in 8pt; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10);">They seem to not cause a problem, the resolver eventually resolves the request.<o:p class=""></o:p></p><p class="Default" style="margin: 0in 0in 8pt 0.25in; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10); text-indent: -0.25in;"><span style="font-family: Symbol;" class=""><span class="">·<span style="font-style: normal; font-variant-caps: normal; font-weight: normal; font-stretch: normal; font-size: 7pt; line-height: normal; font-family: "Times New Roman";" class=""> <span class="Apple-converted-space"> </span></span></span></span>2021 Jun 16 17:17:34+00:00 wglng-17 unbound [err] [12764:0] error: can\'t bind socket: Cannot assign requested address for 192.168.0.131 port 59253 (len 16)<o:p class=""></o:p></p><p class="Default" style="margin: 0in 0in 8pt 0.25in; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10); text-indent: -0.25in;"><span style="font-family: Symbol;" class=""><span class="">·<span style="font-style: normal; font-variant-caps: normal; font-weight: normal; font-stretch: normal; font-size: 7pt; line-height: normal; font-family: "Times New Roman";" class=""> <span class="Apple-converted-space"> </span></span></span></span>2021 Jun 16 17:17:34+00:00 wglng-17 unbound [info] [12764:0] info: error sending query to auth server ip4 8.8.8.8 port 53 (len 16)<o:p class=""></o:p></p><p class="Default" style="margin: 0in 0in 8pt 0.25in; line-height: 12.95pt; font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(0, 0, 10); text-indent: -0.25in;"><span style="font-family: Symbol;" class=""><span class="">·<span style="font-style: normal; font-variant-caps: normal; font-weight: normal; font-stretch: normal; font-size: 7pt; line-height: normal; font-family: "Times New Roman";" class=""> <span class="Apple-converted-space"> </span></span></span></span>2021 Jun 16 17:17:34+00:00 wglng-17 unbound [info] [12764:0] info: processQueryTargets:<span class="Apple-converted-space"> </span><a href="http://www.carillon.ca/" class="">www.carillon.ca</a>.
