bb-services: regexes in expect string? 🔗 link

I have this defined in bb-services:

[smtp-transaction]
        send "helo hobbit.domain.com\r\nmail from: <user-a3d973489fd1@xymon.invalid>\r\nrcpt to: <user-f1d73117a4d8@xymon.invalid>\r\nquit\r\n"
        expect "220-mx01.domain.com ESMTP\r\n220 ESMTP READY\r\n250 mx01.domain.com\r\n250 sender <user-a3d973489fd1@xymon.invalid> ok\r\n"
        port 25

and a host that uses it in bb-hosts.  This works great, except that it's tied to the host mx01.domain.com in the expect string.

Is it possible to use regexes in the expect string, such as expect "220-mx0[0|1].domain.com"?  So far my attempts have been unsuccessful and the man pages don't seem to indicate if this is possible.

I'm wondering about the same, and haven't seen any answer to this.

I'm trying to match some xml, and first line is:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

The problem is the quotes, as bbtest-net terminates the string on the
first quote, no matter what, it seems.

I have tried escaping like this:
expect "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>"

but "bbtest-net --services" shows "Exp.text: <?xml version=", adding more
\ doesnt help, the extra \ will then just be part of Exp.text.

I notice that --services show:
   Exp.text: <?xml version=
   Exp.len : 14
   Exp.ofs : 0

All my services show "Exp.ofs : 0", I suppose "ofs" means offset?
Is there a way to set this to something else than 0?

The services I try to monitor also seems to puke out some ctrl-chars at
the start (and it it uses ssl), a connection with openssl s_client looks
like this:

[snip SSL stuff]
    Verify return code: 19 (self signed certificate in certificate chain)
---
^@^@^D<FE><?xml version="1.0" encoding="UTF-8" standalone="no"?>
[snip rest of xml]

Should my "expect" also include "\x00\x00\x04\xFE" before "<?xml version"?

Again, if I could use regexp, I would probably just go for ".*<?xml ..",
and if offset can be used, I'd jump over the control chars.

Any tip?

I never saw a reply to this, so I'll bump it since I have exactly the same need ;)
