How to disable ICMP ping replies (linux)

Tue, 08 Dec 2020 01:42:00 +0000

Few weeks ago during server setup phase for one of my project, I notice there is no ICMP or ping replies from server and some port are not able to access.

I told the network engineer to check and seem they blocking the ports and disabling ICMP replies from their firewall configuration.

From that accident I do some google-fu if I can do same thing for personal computer / server. We can setting the kernel variable or use iptable to disable ICMP / ping replies if requested.

Sending JSON data file using CURL to API endpoint

Mon, 30 Nov 2020 10:23:00 +0000

I developed warehouse system and use restful as communication method between our software and client software. We let end point of our system to talk each other with API designed.

For simple and small test using Postman or SOAP-UI is enough for me but to when to test this system with massive data via API is quite headache, plus the mock features on Postman limited and not “mocking” enough as I want.

Upgrade Suse Linux Enterprise Server 11 SP1 to SP4

Sun, 27 Sep 2020 03:26:00 +0000

As I mentioned previously, SLES11 is already absolute / not supported anymore. Even most official tutorial are wipe out form suse website.

I will write how I updating my SLES11 to SP4. I don’t have SP1 but it should be work the same as SP2 upgrade to SP3 and SP3 to SP4.

So this is my machine

bash

VM-b0x:convey69:/convey69> uname -a
Linux VM-b0x 3.0.42-0.7-default #1 SMP Tue Oct 9 11:58:45 UTC 2012 (a8dc443) x86_64 x86_64 x86_64 GNU/Linux

VM-b0x:convey69:/convey69> cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 2

why update? Because it better to get recent patch, fix OS vulnerabilities and update kernel (anything as latest we could get! So please do not ask me why need update)

SLES 11 - set DNS manually

Fri, 25 Sep 2020 07:37:00 +0000

Hell yeah, I know SLES11 is absolute / not supported anymore. The latest version are SLES11 SP4, but I still using it on my test Refreshing service ’nu_novell_com’.server. Hmm.. sometimes I forgot how to configure DNS on Suse Linux Enteprise Server (SLES) 11 then I believe puts public notes on my weblog will be great for everyone reference!

back to the topic, setup dns is easier to just overwrite generated file /etc/resolv.conf directly
