Operations on Network Addresses
Hello,
I'm a relatively new user and have run into a problem which may just be a misunderstanding. I'm using the Oct2014 version, installed on Fedora 20 from the MonetDB rpm repository. When I try to query a database using inet "containment" operators like << or <<= it seems that the operators are not recognized:
sql> select src,dst from raw.ids where src << inet'xxx.xxx.xxx.xxx/27'; SELECT: no such binary operator 'left_shift(inet,inet)'
sql> select src,dst from raw.ids where src <<= inet'xxx.xxx.xxx.xxx/27'; syntax error, unexpected '=' in: "select src,dst from raw.ids where src <<="
Other ordinary binary inet operators seem OK:
sql> select src,dst from raw.ids where src = inet'xxx.xxx.xxx.xxx'; (prints out table) sql> select src,dst from raw.ids where src < dst; (prints out table)
However the documented functions do not seem to be recognized:
sql> select masklen(inet'192.168.0.0/24') SELECT: no such unary operator 'masklen(inet)' sql> select netmask(inet'192.168.0.0/24') SELECT: no such unary operator 'netmask(inet)'
So it seems that support for network address types is only partially available in this release. Is that normal? Do I need to rebuild from source in order to get them?
Thanks!
Tim
Hi Tim,
I'm afraid the operations and functions that you want to use have not yet been implemented in MonetDB. Sorry!
Please consider filing a feature request via http://bugs.monetdb.org/
Thanks!

Hello!
Thanks for your note. I'm a little confused because the functions do seem to be in the source code (monetdb5/modules/atoms/inet.c). Is it just that the functions aren't being included in the build?
One reason I ask is that I'd like to experiment with adding IPv6 support, so it would be useful to know how functions like this get linked in (or in this case, not linked in).
Thanks!

Hi,
thank for your feedback, and sorry for my too premature answer.
Indeed, functions masklen() & netmask() are there an work fine for me (yum-installed MonetDB Oct2014 on Fedora 20).
I'm puzzled why it doesn't work with you given a seemingly identical setup. Did you try with a new virgin database, or did you upgrade your database from an earlier MonetDB version?
inet "containment" operators (<< & <<=) appear to be not supported by the parser (which interprets the first a left-shift, and does not recognize the latter as valid operator).
inequality (< & <=) appear to work fine also for me, while equality (=) gives an error.
See details below.
Best, Stefan

Hello!
Hmmm... I did some more experimentation and find that functions like masklen() and host() either work or do not work depending on the username given to mclient. Both users are accessing the same database. The difference is that the user who can use the functions is the authorized owner of the schema:
sql> select masklen(inet'192.168.0.0/24'); +----------------------+ | masklen_single_value | +======================+ | 24 | +----------------------+
while the other user merely has SELECT,INSERT,DELETE on some of the tables:
sql> select masklen(inet'192.168.0.0/24'); SELECT: no such unary operator'masklen(inet)'
Do I need to grant some privileges to the other users so that they can access these functions? Or if there's some information I could send to help figure this out, just let me know.
Thanks very much!

Indeed, functions masklen() & netmask() are there an work fine for me (yum-installed MonetDB Oct2014 on Fedora 20).
I'm puzzled why it doesn't work with you given a seemingly identical setup. Did you try with a new virgin database, or did you upgrade your database from an earlier MonetDB version?
inet "containment" operators (<< & <<=) appear to be not supported by the parser (which interprets the first a left-shift, and does not recognize the latter as valid operator).
inequality (< & <=) appear to work fine also for me, while equality (=) gives an error.
See details below.
Best, Stefan

Hello!
Thanks for your note. I'm a little confused because the functions do seem to be in the source code (monetdb5/modules/atoms/inet.c). Is it just that the functions aren't being included in the build?
One reason I ask is that I'd like to experiment with adding IPv6 support, so it would be useful to know how functions like this get linked in (or in this case, not linked in).
Thanks!

Hello,
I'm a relatively new user and have run into a problem which may just be a misunderstanding. I'm using the Oct2014 version, installed on Fedora 20 from the MonetDB rpm repository. When I try to query a database using inet "containment" operators like << or <<= it seems that the operators are not recognized:
sql> select src,dst from raw.ids where src << inet'xxx.xxx.xxx.xxx/27'; SELECT: no such binary operator 'left_shift(inet,inet)'
sql> select src,dst from raw.ids where src <<= inet'xxx.xxx.xxx.xxx/27'; syntax error, unexpected '=' in: "select src,dst from raw.ids where src <<="
Other ordinary binary inet operators seem OK:
sql> select src,dst from raw.ids where src = inet'xxx.xxx.xxx.xxx'; (prints out table) sql> select src,dst from raw.ids where src < dst; (prints out table)
However the documented functions do not seem to be recognized:
sql> select masklen(inet'192.168.0.0/24') SELECT: no such unary operator 'masklen(inet)' sql> select netmask(inet'192.168.0.0/24') SELECT: no such unary operator 'netmask(inet)'
So it seems that support for network address types is only partially available in this release. Is that normal? Do I need to rebuild from source in order to get them?
Thanks!

What if you try using sys.masklen instead?
Yes, that works! Adding the 'sys.' prefix seems to make the inet functions, and many others (like median(), gethost(), etc), available. Do I have something wrong in the way the users are set up?
The one set of functions that still seem to be unreachable are the inet containment operators like << >> <<= and >>=.
Thanks!

Hello!
Hmmm... I did some more experimentation and find that functions like masklen() and host() either work or do not work depending on the username given to mclient. Both users are accessing the same database. The difference is that the user who can use the functions is the authorized owner of the schema:
sql> select masklen(inet'192.168.0.0/24'); +----------------------+ | masklen_single_value | +======================+ | 24 | +----------------------+
while the other user merely has SELECT,INSERT,DELETE on some of the tables:
sql> select masklen(inet'192.168.0.0/24'); SELECT: no such unary operator'masklen(inet)'
Do I need to grant some privileges to the other users so that they can access these functions? Or if there's some information I could send to help figure this out, just let me know.
Thanks very much!
