Script don't start before long delay when a DNS server is in line but don't send responses
Hi, During some test ... suddenly when I select a script ... I have to wait for a long long time with some messages in the top of the left screen ... I don't remember all of them (except some humorous (I presume) like ... 42 ... and after some time and multiples messages the script start but all seems long. I am on a local LAN with fixed I.P. ... no proxy ... but at the same time I have problem with the DNS of my Internet provider (present but not responding) and when I read the server.log at the time of the problem ... it seems that the delay is linked to a line : [script_server.audit_utils.WARNING] Could not get hostname for 192.168.10.101 ... my box don't have a local DNS and DHCP propose only the Provider DNS servers. when DNS works again ... (so with immediate response (unknown) on hostname request) ALL go back normal.
So clearly it's a VERY RARE case but is it possible (when we use script-server only in a local LAN) to prevent audit (or others) to request hostname to the DNS and keep only the I.P. ?
Or do you think it's another problem ? because script-server require Internet or others services to run as well ?
As I said first, it's not a common situation, so I can understand that it's absolutely not a priority .... And for now, I don't have any idea on how reproduce this problem ...
Philippe. N.B. to introduce me, I am a NAS package integrator (open source) and use script bash to configure applications, I have start to write a webui but it's a lot of works and so specific to each package and your tool (script-server) seem to be a very good and very easy solution (after my first try).
Hi @father-mande, do you have timestamps in the server.log? May be you can check which operation took the most time there?
Hi bugy,
Unfortunately not ... because the problem will appear during the night ... and not only on the server and PC used for test ... I have try a lot of thing (so restarting script-server) ... because I think first : it's my fault I don't realize immediately that I have a provider problem ... considering that script-server is on LAN so without the need to access Internet or external server . This morning the DNS problem has been resolved ... So I restart with a clean situation (so cleaning all logs to get a better trace in a small file) and forgot to keep the old .log (I have also added in the Linux server my I.P. and PC Name in hosts file to prevent DNS access)
I will try to reproduce the problem ... so if (I suppose) you don't have enough information ... just wait or closed this issue ... I will reopen it if I can get more details and logs.
Philippe.
Hi Philippe, why do you delete logs on restart? Or you use docker containers without volumes?
I meant the file, logs/server.log. It should be kept between restarts
Hi, Because I am stupid ... In fact I will start to generate a NAS package (on multiple architecture x86, x86_64, Armhf Arm64) for script-server and tests multiples options ... selecting script based on user_name ... creating multiple instance with separate logs (by changing logging.json and separate port etc. ... generating rotate server.log (on NAS App. run 7/7 24/24) ... etc. etc. ... and at this time I restart with a clean situation for each test ... I have created a series of script to test the usage ... but I am not really in "production" mode
I have hesitate to write the post (due to lack of logs and information) ... but I do it ... in case you know or already have similar problem ... and that you know when an why script-server send waiting message when we call a script ...
Philippe.
Unfortunately I cannot say why it happened, without logs. DNS resolving might be a problem, but there can be different reasons
Hi,
Yes, I understand, I will try to create a DNS server and redo some tests ...
Thanks. Philippe.
Thanks!

Hi, I also faced with this problem:
Jul 13 17:11:36 admin python3[24222]: 2021-07-13 17:11:36,108 [script_server.audit_utils.WARNING] Could not get hostname for 10.31.1.160
If I update my /etc/hosts to add 10.31.1.160 ob, everything starting working very quickly
