Does openwrt support Raspberry Pi 4 Model B 8GB with 7 or 10 inch touch screen display?

Subject: Does openwrt support Raspberry Pi 4 Model B 8GB with 7 or 10 inch touch screen display?

Good day from Singapore,

I am thinking of buying Raspberry Pi 4 Model B 8GB with 7 or 10 inch touch screen display in June 2021.

Raspberry Pi 4 Model B – 8GB (Latest) – Price SGD$120

Do you think it is a good match?

Does openwrt support Raspberry Pi 4 Model B 8GB with 7 or 10 inch touch screen display? I want to configure Raspberry Pi as a wired or wireless router. What other use cases are there for Raspberry Pi using openwrt?

Please give me links to good and well written guides for openwrt and Raspberry Pi.

I am looking forward to your reply.

Thank you very much.

Do you think it is a good match?

I want to use my Raspberry Pi like a regular laptop or desktop computer. Would a 7 inch touch screen display be too small for my use case? I don’t want to strain my eyes looking at a small display. However, if I get a 10 inch touch screen display, I can’t find one with a supporting base. I can’t find a 10 inch touch screen display with a supporting base which could allow the screen to stand vertically.

Finally, does your Linux distribution support Raspberry Pi 4 Model B 8 GB? Can I do 4K Ultra HD video editing on the Raspberry Pi 4 Model B 8 GB? Like adding watermarks, and cutting away unwanted 4K scenes. Is there a good 4K video editing software for Linux?

I am looking forward to your reply.

Thank you very much.

CPF Ordinary Account $27,843

Why is Teo En Ming’s total CPF account so shockingly LOW/MEDIOCRE/MEAGRE/PEANUTS/NEGLIGIBLE/INSIGNIFICANT? Mrs Goh Chok Tong, wife of former Singapore Prime Minister Goh Chok Tong, once said that $600,000 is peanuts. So Teo En Ming’s CPF account is many many times worse than peanuts.

Why is Teo En Ming’s total CPF account so shockingly LOW/MEDIOCRE/MEAGRE/PEANUTS/NEGLIGIBLE/INSIGNIFICANT? Because Turritopsis Dohrnii Teo En Ming is a TARGETED INDIVIDUAL. A Targeted Individual is a person who is persecuted, marked and targeted by the government. He is frequently fired from his jobs for the past 14 years after graduation from the National University of Singapore in December 2006. He is persecuted, targeted, and marked by the Singapore Government after offending the late Minister Mentor of Singapore Lee Kuan Yew in 2007. The Singapore Government is punishing Teo En Ming to ensure that he lives in extreme poverty for eternity. Governments will also arrange for targeted individuals to have numerous health/medical problems (aka “slow kill”).

My Sophos SG-115 rev2 firewall cannot detect Huawei E3276s-920 4G LTE USB modem

Subject: My Sophos SG-115 rev2 firewall cannot detect Huawei E3276s-920 4G LTE USB modem

Good day from Singapore,

My Sophos SG-115 rev 2 firewall cannot detect Huawei E3276s-920 4G LTE USB modem. UTM version is 9.703-3.

Do I need to upgrade the UTM version to get it working? Or perhaps Huawei E3276s-920 4G LTE USB modem is NOT supported at all? I would like to get Huawei E3276s-920 4G LTE USB modem working on my Sophos SG-115 rev 2 firewall.

Background and more troubleshooting details are here:

I am looking forward to your reply.

Thank you very much.

What is the best (and free) Linux softphone?

Subject: What is the best (and free) Linux softphone?

Good day from Singapore,

I already have an Asterisk-based FreePBX VoIP IP PBX SIP server virtual appliance (VirtualBox).

I do not want to spend so much money on buying physical IP phones.

Recently, I migrated my Fortigate 60D firewall, Huawei E3276s-920 4G LTE USB modem, FreePBX virtual appliance (on laptop) and 1 unit of Cisco 7960 IP phone from my home to the community hostel. I cannot migrate too many hardware to the community hostel even though I have 4 Cisco 7960 IP phones.

As stated earlier, I do not want to spend so much money on buying physical IP phones.

I am trying to save as much money as possible as I live in extreme poverty in Singapore. My proposed solution is to install many Linux virtual machines on my laptop. Each Linux virtual machine will have a softphone.

So my ultimate question is: What is the best (and free) Linux softphone available? Do I have many choices?

I am looking forward to your reply.

Thank you very much.

[SOLVED] Webmin web user interface on Linux mail server is inaccessible

Subject: [SOLVED] Webmin web user interface on Linux mail server is inaccessible

Good day from Singapore,

Today 5th May 2021 Wed, my colleague Edward Joseph Snowden (fictitious name used here) told me that Webmin web user interface on client’s Linux mail server is not accessible.

So I putty/ssh into the Linux mail server, which is a CentOS 6.8.

First thing, I checked the configuration of Webmin.

# ps -ef | grep webmin

/usr/bin/perl /usr/libexec/webmin/miniserv.pl /etc/webmin/miniserv.conf

# nano /etc/webmin/miniserv.conf

Partial Contents of /etc/webmin/miniserv.conf:

port=10101

listen=10101

From the above snippets, Webmin is not listening on the default port of 10000 but 10101.

Then I proceeded to check the running Linux iptables firewall rules.

# iptables -S | grep 10101

I noticed that TCP port 10101 is NOT open.

I checked /etc/init.d/iptables

Partial Contents of /etc/init.d/iptables

IPTABLES=iptables

IPTABLES_DATA=/etc/sysconfig/$IPTABLES

IPTABLES_FALLBACK_DATA=${IPTABLES_DATA}.fallback

IPTABLES_CONFIG=/etc/sysconfig/${IPTABLES}-config

IPV=${IPTABLES%tables} # ip for ipv4 | ip6 for ipv6

[ “$IPV” = “ip” ] && _IPV=”ipv4″ || _IPV=”ipv6″

PROC_IPTABLES_NAMES=/proc/net/${IPV}_tables_names

VAR_SUBSYS_IPTABLES=/var/lock/subsys/$IPTABLES

From the above snippet, Linux iptables firewall rules are saved in /etc/sysconfig/iptables

I checked /etc/sysconfig/iptables and noticed that it contains the following line:

[root@mail.teo-en-ming-corp.com init.d]# cat /etc/sysconfig/iptables | grep 10101

-A INPUT ! -i lo -p tcp -m state –state NEW -m tcp –dport 10101 -j ACCEPT

Apparently the saved iptables firewall rules DO allow TCP port 10101.

To solve the problem, I executed the following command.

# service iptables restart

This allows the saved iptables firewall rules to be reloaded. Now TCP port 10101 is open in the Linux iptables firewall.

Besides the above issue, I also noticed that new iptables firewall rules were added to block the Windows Server in the same subnet from accessing it.

# iptables -S | grep xxx

-A DENYIN -s 192.168.1.xxx/32 ! -i lo -j DROP

-A DENYOUT -d 192.168.1.xxx/32 ! -o lo -j LOGDROPOUT

I proceeded to delete the above 2 iptables firewall rules.

# iptables -D DENYIN -s 192.168.1.xxx/32 ! -i lo -j DROP

# iptables -D DENYOUT -d 192.168.1.xxx/32 ! -o lo -j LOGDROPOUT

Now Webmin web user interface is accessible from the Windows Server in the same subnet. Turritopsis Dohrnii Teo En Ming has solved the problem.
