Hi Stefano,
you could try to html encode the "+" and "-" sign in the option list
Options Half = +x, -x, both
Allow HTML = 1

But of course then you would need to change all existing entries.

It is just an idea; I did not try this out, it might not work anyway.

Cheers
Andreas

Hi Stefano,
I've tested it: it does not work.
Neither in edit nor in list view the HTML encoded characters show correctly.
Only in the "Quick filter" menu they show as they should!
But then selecting them in the quick filter will not find any entries :-(

So the short answer: 
avoid characters with a special meaning for regular-expressions in attribute values, in particular if you want to use quick filters.

Hi Susan,

• Hosts allow = <list>
• Hosts deny = <list>

These two settings can be used to restrict the access to the logbook to certain computers. It is similar to the UNIX hosts.allow and hosts.deny files. The list can consist of individual host names or IP numbers, subnet masks like 123.213. (note the trailing '.') or .mit.edu, or the word All. The following rules are applied:

• Access will be granted when a host matches a pattern in "hosts allow".
• Otherwise, access will be denied when a host matches a pattern in "hosts deny".
• Otherwise, access will be granted.

These rules are applied before any password is checked. To debug problems, start elogd with the "-v" flag, in which case the rule checking is printed on the screen.

thanks for your quick reply.

the configuration is still not working.  See my entry below which denies everyone.

I've tried many different combinations of 'hosts allow and hosts deny'

we want to restrict all our logbooks to only domain lbl.gov

[ below denies ALL ]

Hosts allow = .lbl.gov
Hosts deny = ALL

[ below denies ALL ]

Hosts deny = ALL

Hosts allow = .lbl.gov
 

Can you help?

I am not aware that it is forseen to define logical operators in combination with the Style command. How did you get the idea that this should work?

But you should be able to define multiple Style commands, acting on different format parameter.

I have fixed this issue in the current develop branch of elog.

Hi All,

We're still having trouble with hosts.allow and hosts.deny.

We're trying to allow all of our domain  lbl.gov to the access list

for our logbooks.  But the combination below is not working.

==========================

[ below denies ALL ]

Hosts allow = .lbl.gov
Hosts deny = ALL

[ below denies ALL ]

Hosts deny = ALL

Hosts allow = .lbl.gov

========================
Can someone help?
