DD-WRT: inadyn segmentation fault

csak a baj van vele:))
DD-WRT Forum + inadyn segfault:)

saját workaround a fentiek alapján dyndns esetére, slágvortokban:):

Setup --> DDNS --> DDNS Service | DynDNS.org
Setup --> DDNS --> User Name | felhaználó
Setup --> DDNS --> Password | jelszó
Setup --> DDNS --> Host Name | hostnév -a hosztnév1 ...
Setup --> DDNS --> Save
Setup --> DDNS --> DDNS Service | Disable
Setup --> DDNS --> Save

Administration --> Commands --> Commands | (copy-paste)
Save Custom Script (/tmp/custom.sh)

/tmp/custom.sh egyszerűsítése:

valami el lett cseszve: mindenféle nyúzás után is mindig működik:)

vagyis ennyi. úgy tűnik ennél már nem lesz jobb.
