iphone - UDP Packets IOS 9 LTE Network GCDASYNCUDP -

-

i have basestation (beaglebone running linux) @ home connected multiple cameras. connect iphone ios9 basestation via tcp , basestation stream video of each camera specific udp port. well.

i want able see cameras when not connected local network. when phone connected lte, have iphone connecting public address of router via tcp , port forwarding, data forwarded basestation. connecting , talking on local network tcp client. well.

the problem when video streamed via udp on specific port, no different when on local network, basestation has no problem sending packets, iphone not receiving anything. using gcdasyncudpsocket , cellular carrier verizon.

i wondering if issue due verizon blocking udp packets? or possibly there needs else done other binding iphone udp socket specific port , calling beginreceiving function. feel if works on local network, should work on cellular network.

i have tried ping address of cellphone computer not work. guessing reason because iphone has blocked this. should no different pinging address of google or else.

please give me insight on possible issues or work arounds. don't think need port forward udp since outgoing , netgear router not limit outbound traffic (from router iphone). doing tcp before trying send video via udp. slower waiting receive acks 5 cameras streaming live video. , when doesn't receive packet backs buffer , causes more issues. had issue tcp packets combining had implement kind of custom ack made delay worse, or add end of message, slows down on parsing , since don't know data coming made things more difficult.

udp way go, cannot receive packets @ time. understanding lot of games use udp , work on lte network, i'm not quite sure problem is. there special udp ports work verizon?

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
