linux – ping failed but ICMP Echo Reply received

I have a network topology like:

enter image description here

On the host, I had done these scripts before hand:

echo 1 > /proc/sys/net/ipv4/conf/veth1/accept_local
echo 1 > /proc/sys/net/ipv4/conf/veth0/accept_local
echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
echo 0 > /proc/sys/net/ipv4/conf/veth0/rp_filter
echo 0 > /proc/sys/net/ipv4/conf/veth1/rp_filter

When I ran ping -I veth0 192.168.1.3, the ping process was hanging there.
But when I ran tcpdump on lo, I saw ICMP Echo Reply was received.

bash-4.4# tcpdump -i lo -v -nn 'icmp'
dropped privs to tcpdump
tcpdump: listening on lo, link-type EN10MB (Ethernet), capture size 262144 bytes
16:25:40.820115 IP (tos 0x0, ttl 64, id 12130, offset 0, flags (none), proto ICMP (1), length 84)
    192.168.1.3 > 10.0.2.15: ICMP echo reply, id 3446, seq 788, length 64

As you can see, since there is no IP on veth0, OS select eth0’s IP as source IP. But I don’t think this is a big deal. The fact is Echo Reply is really received.

As long as I attach IP to veth0 by ip addr add 192.168.1.2/24 dev veth0, ping will be successful:

bash-4.4# ip a a 192.168.1.2/24 dev veth0
bash-4.4# ping -I veth0 192.168.1.3
PING 192.168.1.3 (192.168.1.3) from 192.168.1.2 veth0: 56(84) bytes of data.
64 bytes from 192.168.1.3: icmp_seq=1 ttl=64 time=0.022 ms
64 bytes from 192.168.1.3: icmp_seq=2 ttl=64 time=0.065 ms

Is there something I missing for ping or for linux kernel?
I ran this experiment on CentOS8 (kernel: 4.18.0)

unity – “Failed to load alembic” Unity3D after build

Facing difficulties with alembic after building for x86_x64 windows. Alembic files aren’t being loaded or read and I am getting this error in the log file

I am using unity 2019.4.16f1 and tried with both Alembic packages 1.0.7(verified with my unity version they say) and 2.1.2

Anyone can help me with this?

linux – clamav-daemon start condition failed, /var/lib/clamav/daily.{c[vl]d,inc} was not met

After installing Modoboa(Open Source Mail Hosting), I Tried to start clamav-daemon, but i faced start condition failed.

   Loaded: loaded (/lib/systemd/system/clamav-daemon.service; enabled; vendor preset: enabled)

           └─ ConditionPathExistsGlob=/var/lib/clamav/daily.{c(vl)d,inc} was not met

Below it showed the problem, conditionPathExistsGlob=/var/lib/clamav/daily.{c(vl)d,inc} was not met.
I couldn’t start the service with systemctl or other commands.
After some troubleshoots, I found out that /var/lib/clamav is empty and there should be some .cvd update file.
Also I couldn’t update the clamav with this command (show me 403 error):

sudo clamav-freshclam

what can I do now?

sql server – conversion failed when converting datetime from character string while inserting and updating to database

I’m trying to insert time and date separately and calculate if it is late to the set time and then insert it to database…

here’s my try code for update

string Date = DateTime.Now.ToString(“dd-MM-yyyy”);
string Time = DateTime.Now.ToString(“h:mm:ss tt”);
SqlCommand comm2 = conn.CreateCommand();
comm2.CommandText = “Update Time_Logs SET Time_Out = ‘” + Time + “‘ where Emp_Id = ‘” + EmpId.Text + “‘ and Date = ‘” + Date + “‘”;
try
{
conn.Open();
comm2.ExecuteNonQuery();
MessageBox.Show(“Time_Out…”);
conn.Close();
TimeCompute();
}
catch (Exception x)
{
MessageBox.Show(x.Message);
conn.Close();
}

and here is the code for inserting

string Date = DateTime.Now.ToString(“dd-MM-yyyy”);
string Time = DateTime.Now.ToString(“h:mm:ss tt”);

        SqlCommand comm = conn.CreateCommand();
        comm.CommandText = "INSERT INTO Time_Logs (Emp_Id, Date, Time_In) VALUES('" + EmpId.Text + "','" + Date + "','" + Time + "')";
        try
        {
            conn.Open();
            comm.ExecuteNonQuery();
            MessageBox.Show("Time_In...");
            conn.Close();
            DateTime time = DateTime.Parse(Time);
            DateTime inDate = DateTime.Parse("8:00:00 AM");
            TimeSpan ts1 = inDate.TimeOfDay;
            TimeSpan ts = time - inDate;
            if (ts < ts1)

sharepoint server – Designer 2010 workflow failed on start with error RunWorkflow: System.UnauthorizedAccessException

We migrated our SharePoint Site from SP 2010 to SP 2013. We have a designer workflow on a custom list and the workflow has couple of approval task forms. The issue we are facing is, workflow ‘Failed on start’ only for the first item added on day. Workflows works fine and assigns task forms as expected from the second item. I checked the ULS logs and I see these messages-

RunWorkflow: System.UnauthorizedAccessException: Access to the path

The name of the dll changes with every day.

Motherboard post DB | Flash update has failed, but I have not updated bios

I own a server which resides locally in my house and I live alone. Last night the machine worked fine and this morning it would not boot. There was a black screen and code ‘db’ displayed on the board LED panel.

The code indicates ‘Flash update has failed’, yet I did not update the bios and cannot see a bios update utility on my machine. I booted on the backup bios and triggered recovery but would like to know what the cause might be.
