Hi Nick, You mean child hung issue is not happening with version 2.2.9? since it has been fixed in version 2.2.0. On Thu, Oct 1, 2015 at 11:00 AM, Nick Lowe <nick.lowe@gmail.com> wrote:

I mean that as lot has been fixed between 2.2.0 and 2.2.9, I casually remember reading about fixes for hung children. This could, of course, be for unrelated causes. As a general rule of thumb, try and reproduce your problem with the latest stable version of the software before asking something like this. Nick

Thanks for your reply. I will use latest version (3.0.9). I believe that there is no need of changing the code of our custom module due to version change?

Unlikely. But we can't see your code, so it makes it quite difficult to help...

Hope there is no data structure change happened between version 2.2.0 to 3.0.9.

Lots has changed between those versions. Why would you think nothing would be different between major releases?

I am sorry if the question seems to be basic and I have to try and find it out.

If you can write your own module then surely you could at least *try* to compile it against the new version and see what happens? Then you can ask better questions.

Hi,

Thanks for your reply. I will use latest version (3.0.9). I believe that

why? you've got 2.0.0 module and code.... you've been told to try your stuff with 2.2.9

change? Hope there is no data structure change happened between version 2.2.0 to 3.0.9.

LOADS of things have been changed between 2.x and 3.x - thats why its a major version release - in the first instance look at the developers docs and read the API and data structure changes - its not a 'compile it as is' process unless your module is very very simple bump your local box to 2.2.9 codebase and start there - there have been thousands of code lines change between those versions and hundreds of bugs/fixes some of which might solve your problem. i can say this though in the first instance, unless you are using 2.2.9 your issue wont get looked at as its likely tohave already been fixed since 2.2.0 alan

Is there any throttling done at Free Radius server (latest version 3.0.9)? so that when external module response is slow, Radius server would not fill the queue with incoming messages (from NAS). i.e. taking messages into queue and run into child hung issue. It uses throttling to have control over pending request queue when there is a slowness in the external system and queue size increases (since NAS is flooding the radius server).

I suggest you read radiusd.conf that comes with whatever version of FR you installed first, and see if the tunables there are enough for your purposes.

Do you want to automatically increase max_requests? Until how big, unlimited? And what do you want to do with requests already handled, keep waiting forever?

If you have "slow response from external module", then you should fix that module. For example,

http://lists.freeradius.org/pipermail/freeradius-users/2013-June/066900.html

There's also https://github.com/FreeRADIUS/freeradius-server/issues/880 , so if you get that similar error message, latest 2.x should already fix that.

Your earlier mail shows /opt/csw. Have you checked https://www.opencsw.org/get-it/packages/ ? I haven't used solaris for some time, but I'm pretty sure you also need a ".so" file (which is usually provided by -dev/devel packages) when linking against a library. Your earlier ls output does not have that. -- Fajar On Thu, Nov 5, 2015 at 4:07 PM, srithar jeevadurai <srijeevadurai1@gmail.com

you need proper GNU grep and not the stupid grep that comes with Solaris

Ah yes, the joys of Solaris. That brings back memories I'd rather forget. In less than a quarter of the time you'd wasted making the system usable by installing all the GNU tools in /opt/csw or /usr/gnu and adjusted everything so they were used by default, you may as well have just installed Linux.

From what I understand the only reason people still use it these days is for ZFS. And even then you might as well just install FreeBSD.

Dear Friends,

Thanks for the reply. I have /usr/bin/grep and /usr/sfw/bin/ggrep.

As per your reply, it suppose to use /usr/sfw/bin/ggrep instead of /usr/bin/grep.

To do the same, export PATH=/usr/sfw/bin:/usr/bin:$PATH ---> so that ggrep path comes first in the path variable.

After doing the same, we have to run the ./config once again then gmake (gmake install after that).

Is my understanding correct ?

Dear Friends, It tried by adding ggrep path in PATH variable as first path even though I am getting same error message. My doubt is that gmake command calls a script which uses grep however gun grep in solaris is ggrep. I am able to successfully compile 2.2.9. (after trying and failed with 3.0.9) in the same environment. I have faced only error while compiling rlm_unix module, as per Alan's reply for one of old thread, I removed rlm_unix and successfully installed 2.2.9 in the environment. I am facing difficulty only with 3.0.9 on Solaris 11. 1) While configure step, I faced below WARNINGS. hope I can ignore those. checking for redisConnect in -lhiredis... no checking for redisConnect in -lhiredis in /usr/local/lib... no checking for redisConnect in -lhiredis in /opt/lib... no configure: WARNING: hiredis libraries not found. Use --with-redis-lib-dir=<path>. configure: WARNING: silently not building rlm_rediswho. configure: WARNING: FAILURE: rlm_rediswho requires: hiredis.h libhiredis. 2) while doing gmake I faced following errors. GNU grep on solaris is ggrep, since script is using "grep" though I added GNU utilities path (/usr/sfw/bin) as first in the PATH variable, it is not able to make use since name is ggrep. I believe that if I create symbolic link as grep to ggrep in the path /usr/sfw/bin then It may resolve. Please correct me on the same.

An alias won't help scripts; you need a correctly named binary or a symlink.

Then hope the build scripts don't call another binary that's been updated in the last 15 years. Rinse and repeat.

Hi,

My intention is to find out any way to make FR server resume automatically instead of restarting it when such scenario happen (child hung) due to external module's slowness.

the server should recover on its own when the external source can finally keep up. if theres a bug thats causes a hang instead then that needs looking at... BUT it may have already been fixed since 2.2.0 which is *very * old ( seen its release date? :/ ) so try with 2.2.9 the next step is to find out why your external system is slow to respond. sort that out as when NAS devices send a request, they want an answer. alan
