I am communicating with two devices using my computer over UDP protocol. The application is running fine. When I monitored the UDP traffic using Wireshark software, I found that there were too many Checksum errors.
Please find attached the png file showing this error. I am about to deliver the solution to the customer and have full confidence that the communication is ok. I have however little knowledge in the field of networking.
Any comments on these checksum errors will help me put a strong technical report to the customer.
Does anyone know the answer to this?
When I run "sum -r" on a file that I've down loaded from the sco website, the 1st set of numbers differs from the checksum on the download page but the
2nd set matches.
If I try to install the patch, I get errors.
Anyone has an answer? (3 Replies)

Also is there any way that... (3 Replies)

fruadm
fruadm(1M) System Administration Commands fruadm(1M)NAME
fruadm - prints and updates customer data associated with FRUs
SYNOPSIS
/usr/platform/sun4u/sbin/fruadm
/usr/platform/sun4u/sbin/fruadm -l
/usr/platform/sun4u/sbin/fruadm [-r] path [text]
DESCRIPTION
fruadm prints or sets the customer data for Field-Replaceable Units (FRUs).
Without arguments, fruadm prints the paths of all FRU ID-capable FRUs (containers) in the system, along with the contents of the customer
data record, if present, for each such FRU; for FRUs without customer data, fruadm prints only the container's path.
Only a privileged user can create or update data in containers. The privileges required to perform these write operations are hardware
dependent. Typically, a default system configuration restricts write operations to the superuser or to the platform-administrator user.
OPTIONS
The following options are supported:
-l List the system's frutree paths.
-r Recursively display or update the data for all containers rooted at the argument path.
OPERANDS
The following operands are supported:
path A full or partial system frutree path for or under which to print or set the customer data. The first field of each
line of output of fruadm -l gives the valid full frutree paths for the system.
Paths can include shell meta-characters; such paths should be quoted appropriately for the user's shell. For par-
tial paths, the first matching full path is selected for display or update. Without the -r option, the path must be
that of a container; with the -r option, all containers (if any) under path will be selected.
text Up to 80 characters of text set as the customer data. If the text contains white space or shell metacharacters, it
should be quoted appropriately for the user's shell.
EXAMPLES
Example 1: Displaying All Customer Data
The following example prints all customer data available from FRUs on the system. For containers with no customer data, only the contain-
ers' paths will be listed.
example% fruadm
Example 2: Displaying Customer Data For a Single FRU
The following command prints the customer data, if present, for the specified FRU:
example% fruadm /frutree/chassis/system-board
Example 3: Displaying Customer Data For a Single FRU
The following command prints the customer data, if present, for the first mem-module found:
example% fruadm mem-module
Example 4: Setting Customer Data
The following example sets the customer data for a FRU:
example# fruadm system-board 'Asset Tag 123456'
Example 5: Setting Customer Data
The following command sets the customer data for all FRUs under chassis:
example# fruadm -r /frutree/chassis "Property of XYZ, Inc."
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
