Con you provide a configuration to reproduce the issue?

If your configuration contains sensitive data you can PM it to me

just what I've post
dynamic {

interface eth1 {
    service dyndns {
        host-name xxxxx.mine.nu
        host-name yyyyy.dnsalias.com
        login someuser
        password somepsw
    }
    use-web {
        skip "this is your IP"
        url http://www.web.net/GetRemoteIP.asp
    }
}

}

I suspect that the offending part may be

skip "this is your IP"

and the "ghost" host may be the "is" (part of "this is your IP")

Effectively the web page http://www.web.net/GetRemoteIP.asp only return the IP without "this is your IP"
but this should not put ddclient on failure.... IMO

Actually as workaround, I've completely removed the statement

skip "this is your IP"

and now there is no more ghost-host "is".

But I suspect that the statement-skip functionality is broken IMO.

I will test using a "skip" with some string effectively returned on web page....

if we use a more simply string without blank as e.g.

skip "yourIP"

all seems OK. So I think there is some problem in parsing a whole quoted string.

Ah, there was a similar issue with dhcp last couple of weeks where quotes broke the config (T1129). Can you try using &nbsp instead of your whitespace?

An easier solution is to wrap the test in ' like use-web='this is your IP'

Implemented in latest rolling and backported to Crux branch for 1.2.1
