AIX:
# csum -h MD5 filepath
Solaris:
# digest -a md5 -v filepath

Compare the checksum of the file on the source with the one reported by Aspera.
• If they do not match, then corruption occurred when the file was read from the source. Download the file again
and confirm that it is not corrupted on the destination. If it is corrupted, continue to the next step.
• If they match, confirm that the source file is not corrupted. If the source file is corrupted, replace it with an
uncorrupted one, if possible, and then download the file again.
Server Logging Configuration for Ascp and Ascp 4
Server transfer logs are stored in the default location (see Log Files on page 348), rotated once they are 10 MB,
and log at "log" level. For ascp transfers, you can configure a different default log directory, log size, and logging
intensity on the server, and apply these settings globally or to specific users. For Ascp 4 transfers, you can configure a
default log size (Ascp 4 does not support user-specific logging settings).
If the client specifies a log directory on the server (using -R remote_log_dir) or the location and size of the
local log directory (using -L local_log_dir[:size]), then these take precedence over the server settings.
Default vs User-specific Settings
You can set the default logging configuration or assign users to different logging classes, which are sets of logging
configurations.
Note: Default settings override user-specific settings. To enable user-specific settings, do not set default settings.
User settings do not apply to Ascp 4 transfers.
Configuration Methods
Logging settings are configured by running asconfigurator commands (recommended) or by manually editing
aspera.conf. To edit aspera.conf, open it with admin privileges from the following location:
/opt/aspera/etc/aspera.conf
1.
To set default logging values, run the following commands, as required:
# asconfigurator -x "set_logging_data;directory,logging_directory"
# asconfigurator -x "set_logging_data;log_size,size_mb"
# asconfigurator -x "set_logging_data;level,log_level"
Object Description
directory The full path to the logging directory. Applies only to
ascp transfers.
log_size The size of the log file, in MB, at which it is rotated
