CA and EPICS_CA_ADDR_LIST

Hi,

I do:

setenv EPICS_CA_ADDR_LIST "129.57.160.18 129.57.160.19 129.57.160.15
129.57.160.16 129.57.236.69 129.57.236.67 129.57.236.111"

I need to get things from all these IOC's, and will soon have to add
more. I am not on the subnet for any of them.

It seems like the 2nd half of the addr list is ignored. I.e. I can
read from IOC's up to 129.57.160.16 (I think), but not from the rest
of the list. If I move an address from the end to the beginning, I
can read from that IOC, but lose one down the line.

It looks like there's a character limit on EPICS_CA_ADDR_LIST. If so,
can it be increased dramatically?

Is it possible to specify a subnet mask, as many addresses are on the
same subnet?

I have no way around this...I must read channels from all these IOC's
on our online computer (clon00) at the beginning of each Hall B run.
Our run starts next week....

Sincerely,
Elliott Wolin
