      Here is a script that pulls the serialnumber from a device’s firmware and autopopulates it in the “Enter hostname for this computer:” field during Full Registration. The script is /images/postiniscripts/fog.customhostname. I can ping 8.8.8.8 from the FOG server so I don’t think UFW is blocking that. Important note, when UFW is disabled, there is no delay.

      #!/bin/bash

zmyip=`ip route get 8.8.8.8 | awk 'NR==1 {print $NF}' | cut -d "." -f1-2`;

case "${zmyip}" in
     10.1)
         zsitecode="NYC";
         ;;
     10.2)
         zsitecode="LA";
         ;;
     *)
         # Default code for the unknowns
         zsitecode="CRP";
         ;;
esac

zchassis=`dmidecode -s chassis-type`;
zchassis="${zchassis%"${zchassis##*[![:space:]]}"}";  #Remove training space
zchassis="${zchassis,,}"; # Convert string to lower

if [ "$zchassis" == "laptop" ]; then
    zchtype="P";
elif [ "$zchassis" == "tablet" ]; then
    zchtype="T";
else
    # Everything else is a desktop
    zchtype="D";
fi

zserialno=`dmidecode -s chassis-serial-number`;
zserialno="${zserialno%"${zserialno##*[![:space:]]}"}";  # Remove trailing whitespace

# get the serial no from the baseboard if chassis doesn't give it up
if [ "$zserialno" == "" ]; then
    zserialno=`dmidecode -s baseboard-serial-number`;
    zserialno="${zserialno%"${zserialno##*[![:space:]]}"}";
fi

LEN=$(echo ${#zserialno});
if [ "$LEN" -gt 11 ]; then
    # get the right most characters of the serial number (usually the most
    # unique characters). Logic for 11 is Site(3)+HW(1)+Serial(11)=15 characters
    zserialno=${zserialno:(-11)};
fi

# default host name is returned to the fog.man.reg script
host_default_name="$zserialno";

      Here are my UFW rules in /etc/ufw.user.rules:

      ### RULES ###

### tuple ### allow tcp 3306 0.0.0.0/0 any fogserver2 in
-A ufw-user-input -p tcp --dport 3306 -s fogserver2 -j ACCEPT

### tuple ### allow tcp 21,80,111,138,139,443,445,2049,20048 0.0.0.0/0 any 0.0.0.0/0 in
-A ufw-user-input -p tcp -m multiport --dports 21,80,111,138,139,443,445,2049,20048 -j ACCEPT

### tuple ### allow udp 66,67,68,69,111,137,4011 0.0.0.0/0 any 0.0.0.0/0 in
-A ufw-user-input -p udp -m multiport --dports 66,67,68,69,111,137,4011 -j ACCEPT

      This is the screen where there is a huge delay

      then it skips the Post init script

        @brakcounty to confirm, you mention that with UFW disabled, there is no delay. is the script running however?

          @p4cm4n Yes, the script runs without delay when UFW is disabled.

              I tried disabling the fog.customhostname postinit script, the delay is still there. I tried changing 8.8.8.8 in the script to our own internal DNS server, same result. I don’t know if this is a Linux or FOG issue, hopefully someone can shed some light, but I’ll keep digging.

                @brakcounty said in FOG delay then skip "Running post init scripts..." with UFW Enabled:

                Yes, the script runs without delay when UFW is disabled.

                I wonder if we could craft a deny rule that logs the results so we can see what its not happy about.

                FOG uses nfs, ftp, http, tftp, ssh protocols.

                Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                  @george1421 This is the log from ufw that I just pulled while trying it again, hopefully it shows something useful. I’m not sure what port is defined as here:

                    @brakcounty Well that port doesn’t ring a bell, but I can give you a few more debugging tips. When that error is being generated there is an additional command to see what has that port. netstat -anp should list all of the open ports and the pid or app names associated with the port. I suspect this is a dynamic port related to nfs.

                    Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                      @george1421 I found this after running netstat -anp | grep 41257

                      tcp        0      0 0.0.0.0:41257           0.0.0.0:*               LISTEN      903/rpc.mountd

                      I will try to allow TCP 41257 incoming and report back.

                        THAT WAS IT!!!

                        I had to allow incoming 41257/tcp and now the postinit script runs and the customhostname script runs without delay!

                          @brakcounty I think that is a dynamic port so it may move once the rpc server is restarted. Just be aware of that. NFSv3 has wide open port range. NFSv4 can be restricted to one port.

                            @george1421 Ah so that is a dynamic port for both incoming and outgoing? Because I noticed in the logs that the outgoing kept changing but incoming 41257/tcp remained constant. I’ve read the NFSv4 tutorial and it does seem a bit involved. I have to study it further until I’m comfortable to move from v3 to v4.

                              @george1421 As you said those ports are dynamic, however I found a way to lock some ports to make sure they don’t change from this thread

                              I did everything except RPCRQUOTADOPTS and the post init scripts ran fine without delay. I’m assuming this won’t change as I had to restart the nfs-kernel-server.service to apply the changes. Hopefully this will stick.

                              Small note at the bottom of the linked thread, make sure you allow the ports in ufw.
