General syslog-ng settings

To configure the general options of the syslog-ng server running on SSB, navigate to Log > Options. The following options are available (note that options related to name resolution are discussed in Using name resolution on SSB):

Figure 124: Log > Options — Configuring syslog-ng options

  • Message size: Specifies the maximum length of incoming log messages in bytes. This option corresponds to the log-msg-size() parameter of syslog-ng. The maximum value of this parameter is 1000000 (1 MB).


    To be able to edit the Message size, you must have write/perform permission for the Basic Settings > System page. For details on how to assign user rights, see Managing user rights and usergroups.

  • Wait time between polls: The time to wait in milliseconds before checking if new messages have arrived to a source. This option corresponds to the time-sleep() parameter of syslog-ng.

  • Idle time before destination is closed: The time to wait in seconds before an idle destination file is closed. This option corresponds to the time-reap() parameter of syslog-ng.

  • Cipher: Select the cipher method used to encrypt the logstore. The following cipher methods are available: aes-128-cbc, aes-128-cfb, aes-128-cfb1, aes-128-cfb8, aes-128-ecb, aes-128-ofb, aes-192-cbc, aes-192-cfb, aes-192-cfb1, aes-192-cfb8, aes-192-ecb, aes-192-ofb, aes-256-cbc, aes-256-cfb, aes-256-cfb1, aes-256-cfb8, aes-256-ecb, aes-256-ofb, aes128, aes192, aes256, bf, bf-cbc, bf-cfb, bf-ecb, bf-ofb, cast5-cbc, cast5-cfb, des-cbc, des-cfb, des-cfb1, des-cfb8, des-ecb, des-ede, des-ede-cbc, des-ede-cfb, des-ede-ofb, des-ede3, des-ede3-cbc, des-ede3-cfb, des-ede3-ofb, des-ofb, desx-cbc, rc2-40-cbc, rc2-64-cbc, rc2-cbc, rc2-cfb, rc2-ecb, rc2-ofb, rc4, and rc4-40.

    By default, SSB uses the aes-256-cbc method.

  • Digest: Select the digest method to use. The following digest methods are available: MD4, MD5, SHA-1, RIPEMD-160, SHA-224, SHA-256, SHA-384, and SHA-512.

    By default, SSB uses the SHA-256 method.


    The size of the digest hash must be equal to or larger than the key size of the cipher method. For example, to use the aes-256-cbc cipher method, the digest method must be at least SHA-256.
