########## File path: libs/libc/netdb/lib_dnsaddserver.c ########## @@ -87,7 +87,7 @@ int dns_add_nameserver(FAR const struct sockaddr *addr, socklen_t addrlen) int status; int ret; - stream = fopen(CONFIG_NETDB_RESOLVCONF_PATH, "at"); + stream = fopen(CONFIG_NETDB_RESOLVCONF_PATH, "r"); Review comment: In that case, I think the original author intended "a+" for "append/update." However, there is a bigger problem because as Surya points out, "We have experimented with "a+" "w+" etc but these did not work because of the "resolv.conf" file resides in /etc directory in ROMFS, ROMFS supports only "r" mode."
