Hi Henry,
indeed, port 8080 seems to be not open. The other port, 8088, looks a bit
capricious, a "moody" one... It gives two different answers, depending on
the time when you telnet to it (see below):
[testuser@lcg-ui01 testuser]$ telnet lcg-mon.usatlas.bnl.gov 8088
> Trying 130.199.6.136...
> telnet: connect to address 130.199.6.136: Connection refused
or,
> $ telnet lcg-mon.usatlas.bnl.gov 8088
> Trying 130.199.6.136...

We were told that both ports had been opened long time ago and I haven't
worried a bit about them (too bad !). The problem should be clarified
tomorrow, hopefully, after talking to the network guys in charge of
"drilling" the holes in the firewalls (our LCG-2 nodes are behind
two firewalls). We'll see after that whether "edg-rgma-check" has better
news for us...

I was going to point that out, as that's what I usually see, but of two
"MON" boxes here one closes the connection immediately, while the other
holds it open for ~six minutes

Trying 193.62.142.42...
Connected to dgc-grid-42.
Escape character is '^]'.
...
Connection closed by foreign host.
I hope this is something to do with whether a MON box already has a
Stream
Producer running, rather than dgc-grid-42 being broken!

Yes - I time out too.
