Glacier2.AddConnectionContext
Synopsis
Glacier2.AddConnectionContext=num
Description
If num
is set to 1 or 2, Glacier2 adds a number of key-value pairs to the request context that it sends with each request. If num
is set to 1, these entries are added to the context for all forwarded requests. If num
is set to 2, the contexts are added only to calls to checkPermissions
and authorize
on permission verifiers, and to calls to create
on session managers.
If num is non-0, Glacier2 adds the following context entries:
| The type of the connection as returned by |
| The local address (TCP and SSL only). |
| The local port (TCP and SSL only). |
| The remote address (TCP and SSL only). |
| The remote port (TCP and SSL only). |
| The cipher (SSL only). |
| The first certificate of the client certificate chain (SSL only). |
The default value is 0, meaning that no contexts are added.
Glacier2.AddUserToAllowCategories
Synopsis
Glacier2.AddUserToAllowCategories=num
Description
Specifies whether to add an authenticated user ID to the Glacier2.AllowCategories
property when creating a new session. The legal values are shown below:
0 | Do not add the user ID (default). |
1 | Add the user ID. |
2 | Add the user ID with a leading underscore. |
This property is deprecated and supported only for backward-compatibility. New applications should use Glacier2.Filter.Category.AcceptUser
.
Glacier2.Admin.AdapterProperty
Synopsis
Glacier2.Admin.AdapterProperty=value
Description
Glacier2 uses the adapter name Glacier2.Admin
for its administrative object adapter. Therefore, adapter properties can be used to configure this adapter.
The Glacier2.Admin.Endpoints
property must be defined to enable the administrative object adapter.
Glacier2's administrative interface allows a remote client to shut down the router; we generally recommend the use of endpoints that are accessible only from behind a firewall.
Glacier2.AllowCategories
Synopsis
Glacier2.AllowCategories=list
Description
Specifies a white space-separated list of identity categories. If this property is defined, then the Glacier2 router only allows requests to Ice objects with an identity that matches one of the categories from this list. If Glacier2.AddUserToAllowCategories
is defined with a non-0 value, the router automatically adds the user ID of each session to this list.
This property is deprecated and supported only for backward-compatibility. New applications should use Glacier2.Filter.Category.Accept
.
Glacier2.Client.AdapterProperty
Synopsis
Glacier2.Client.AdapterProperty=value
Description
Glacier2 uses the adapter name Glacier2.Client
for the object adapter that it provides to clients. Therefore, adapter properties can be used to configure this adapter.
This adapter must be accessible to clients of Glacier2. Use of a secure transport for this adapter is highly recommended.
Note that Glacier2.Registry.Client.Endpoints
controls the client endpoint for Glacier2. The port numbers 4063 (for TCP) and 4064 (for SSL) are reserved for Glacier2 by the Internet Assigned Numbers Authority (IANA).
Glacier2.Client.AlwaysBatch
Synopsis
Glacier2.Client.AlwaysBatch=num
Description
If num
is set to a value larger than 0, the Glacier2 router always batches queued oneway requests from clients to servers regardless of the value of their _fwd
contexts. This property is only relevant when Glacier2.Client.Buffered
is enabled. The default value is 0
.
Glacier2.Client.Buffered
Synopsis
Glacier2.Client.Buffered=num
Description
If num
is set to a value larger than 0, the Glacier2 router operates in buffered mode, in which incoming requests from clients are queued and processed in a separate thread. If num
is set to 0, the router operates in unbuffered mode in which a request is forwarded in the same thread that received it. The default value is 0
.
Glacier2.Client.ForwardContext
Synopsis
Glacier2.Client.ForwardContext=num
Description
If num
is set to a value larger than 0, the Glacier2 router includes the request context when forwarding requests from clients to servers. The default value is 0
.
Glacier2.Client.SleepTime
Synopsis
Glacier2.Client.SleepTime=num
Description
If num
is set to a value larger than 0, the Glacier2 router sleeps for the specified number of milliseconds after forwarding all queued requests from a client. This delay is useful for batched delivery because it makes it more likely for events to accumulate in a single batch. Similarly, if overrides are used, the delay makes it more likely for overrides to actually take effect. This property is only relevant when Glacier2.Client.Buffered
is enabled. The default value is 0
.
Glacier2.Client.Trace.Override
Synopsis
Glacier2.Client.Trace.Override=num
Description
If num
is set to a value larger than 0, the Glacier2 router logs a trace message whenever a request was overridden. The default value is 0
.
Glacier2.Client.Trace.Reject
Synopsis
Glacier2.Client.Trace.Reject=num
Description
If num
is set to a value larger than 0, the Glacier2 router logs a trace message whenever the router's configured filters reject a client's request. The default value is 0
.
Glacier2.Client.Trace.Request
Synopsis
Glacier2.Client.Trace.Request=num
Description
If num
is set to a value larger than 0, the Glacier2 router logs a trace message for each request that is forwarded from a client. The default value is 0
.
Glacier2.CryptPasswords
Synopsis
Glacier2.CryptPasswords=file
Description
Specifies the file name of a Glacier2 access control list. Each line of the file must contain a user name and an encrypted password, separated by white space, as described in Writing a Password File. This property is ignored if Glacier2.PermissionsVerifier
is defined.
Glacier2.Filter.AdapterId.Accept
Synopsis
Glacier2.Filter.AdapterId.Accept=list
Description
Specifies a space-separated list of adapter identifiers. If defined, the Glacier2 router filters requests so that it only allows requests to Ice objects with an adapter identifier that matches one of the entries in this list.
Identifiers that contain spaces must be enclosed in single or double quotes. Single or double quotes that appear within an identifier must be escaped with a leading backslash.
Glacier2.Filter.Address.Accept
Synopsis
Glacier2.Filter.Address.Accept=list
Description
Specifies a space-separated list of address-port pairs. When defined, the Glacier2 router filters requests so that it only allows requests to Ice objects through proxies that contain network endpoint information that matches an address-port pair listed in this property. If not defined, the default value is *
, which indicates that any network address is permitted. Requests accepted by this property may be rejected by the Glacier2.Filter.Address.Reject
property.
Each pair is of the form address
or address:port
. The address
portion can include wildcards ('*
'). Port selection can be individual, value ranges, or groups. Ranges and groups have the form [value1,value2,value3,...]
and/or [value1-value2]
. If the port
section is unspecified then all ports will be permitted.
Glacier2.Filter.Address.Reject
Synopsis
Glacier2.Filter.Address.Reject=list
Description
Specifies a space-separated list of address-port pairs. When defined, the Glacier2 router rejects requests to Ice objects through proxies that contain network endpoint information that matches an address-port pair listed in this property. If not set, the Glacier2 router allows requests to any network address unless the Glacier2.Filter.Address.Accept
property is set, in which case requests will be accepted or rejected based on the Glacier2.Filter.Address.Accept
property. If both the Glacier2.Filter.Address.Accept
and Glacier2.Filter.Address.Reject
properties are defined, the Glacier2.Filter.Address.Reject
property takes precedence.
Each pair is of the form address
or address:port
. The address
portion can include wildcards ('*
'). Port selection can be individual, value ranges, or groups. Ranges and groups have the form [value1,value2,value3,...]
and/or [value1-value2]
. If the port
section is unspecified then all ports will be rejected.
Glacier2.Filter.Category.Accept
Synopsis
Glacier2.Filter.Category.Accept=list
Description
Specifies a space-separated list of identity categories. If defined, the Glacier2 router filters requests so that it only allows requests to Ice objects with an identity that matches one of the categories in this list. If Glacier2.Filter.Category.AcceptUser
is defined with a non-0 value, the router automatically adds the user name of each session to this list.
Categories that contain spaces must be enclosed in single or double quotes. Single or double quotes that appear within a category must be escaped with a leading backslash.
Glacier2.Filter.Category.AcceptUser
Synopsis
Glacier2.Filter.Category.AcceptUser=num
Description
Specifies whether to add an authenticated user ID to the Glacier2.Filter.Category.Accept
property when creating a new session. The legal values are shown below:
0 | Do not add the user ID (default). |
1 | Add the user ID. |
2 | Add the user ID with a leading underscore. |
Glacier2.Filter.Identity.Accept
Synopsis
Glacier2.Filter.Identity.Accept=list
Description
Specifies a space-separated list of identities. If defined, the Glacier2 router filters requests so that it only allows requests to Ice objects with an identity that matches one of the entries in this list.
Identities that contain spaces must be enclosed in single or double quotes. Single or double quotes that appear within an identity must be escaped with a leading backslash.
Glacier2.Filter.ProxySizeMax
Synopsis
Glacier2.Filter.ProxySizeMax=num
Description
If set, the Glacier2 router rejects requests whose stringified proxies are longer than num
. This helps secure the system against attack. If not set, Glacier2 will accept requests using proxies of any length.
Glacier2.InstanceName
Synopsis
Glacier2.InstanceName=name
Description
Specifies a default identity category for the Glacier2 objects. If defined, the identity of the Glacier2 administrative interface becomes name/admin
and the identity of the Glacier2 router interface becomes name/router
.
If not defined, the default value is Glacier2
.
Glacier2.PermissionsVerifier
Synopsis
Glacier2.PermissionsVerifier=proxy
Description
Specifies the proxy of an object that implements the Glacier2::PermissionsVerifier
interface for controlling access to Glacier2 sessions. The router invokes this proxy to validate the user name and password of each new session. Sessions created from a secure connection are verified by the object specified in Glacier2.SSLPermissionsVerifier
. For simple configurations, you can specify the name of a password file using Glacier2.CryptPasswords
.
Glacier2 supplies a "null" permissions verifier object that accepts any username and password combination for situations in which no authentication is necessary. To enable this verifier, set the property value to instance/NullPermissionsVerifier
, where instance
is the value of Glacier2.InstanceName
.
As a proxy property, you can configure additional aspects of the proxy using properties.
Glacier2.ReturnClientProxy
Synopsis
Glacier2.ReturnClientProxy=num
Description
If num
is a value greater than 0, Glacier2 maintains backward compatibility with clients using Ice versions prior to 3.2.0. In this case you should also define Glacier2.Client.PublishedEndpoints
to specify the endpoints that clients should use to contact the router. For example, if the Glacier2 router resides behind a network firewall, the Glacier2.Client.PublishedEndpoints
property should specify the firewall's external endpoints.
If not defined, the default value is 0.
Glacier2.RoutingTable.MaxSize
Synopsis
Glacier2.RoutingTable.MaxSize=num
Description
This property sets the size of the router's routing table to num
entries. If more proxies are added to the table than this value, proxies are evicted from the table on a least-recently used basis.
Clients based on Ice version 3.1 and later automatically retry operation calls on evicted proxies and transparently re-add such proxies to the table. Clients based on Ice versions earlier than 3.1 receive an ObjectNotExistException
for invocations on evicted proxies. For such older clients, num
must be set to a sufficiently large value to prevent these clients from failing.
The default size of the routing table is 1000.
Glacier2.Server.AdapterProperty
Synopsis
Glacier2.Server.AdapterProperty=value
Description
Glacier2 uses the adapter name Glacier2.Server
for the object adapter that it provides to servers. Therefore, adapter properties can be used to configure this adapter.
This adapter provides access to the SessionControl
interface and must be accessible to servers that call back to router clients.
Glacier2.Server.AlwaysBatch
Synopsis
Glacier2.Server.AlwaysBatch=num
Description
If num
is set to a value larger than 0, the Glacier2 router always batches queued oneway requests from servers to clients regardless of the value of their _fwd
contexts. This property is only relevant when Glacier2.Server.Buffered
is enabled. The default value is 0
.
Glacier2.Server.Buffered
Synopsis
Glacier2.Server.Buffered=num
Description
If num
is set to a value larger than 0, the Glacier2 router operates in buffered mode, in which incoming requests from servers are queued and processed in a separate thread. If num
is set to 0, the router operates in unbuffered mode in which a request is forwarded in the same thread that received it. The default value is 0
.
Glacier2.Server.ForwardContext
Synopsis
Glacier2.Server.ForwardContext=num
Description
If num
is set to a value larger than 0, the Glacier2 router includes the request context when forwarding requests from servers to clients. The default value is 0
.
Glacier2.Server.SleepTime
Synopsis
Glacier2.Server.SleepTime=num
Description
If num
is set to a value larger than 0, the Glacier2 router sleeps for the specified number of milliseconds after forwarding all queued requests from a server. This delay is useful for batched delivery because it makes it more likely for events to accumulate in a single batch. Similarly, if overrides are used, the delay makes it more likely for overrides to actually take effect. This property is only relevant when Glacier2.Server.Buffered
is enabled. The default value is 0
.
Glacier2.Server.Trace.Override
Synopsis
Glacier2.Server.Trace.Override=num
Description
If num
is set to a value larger than 0, the Glacier2 router logs a trace message whenever a request is overridden. The default value is 0
.
Glacier2.Server.Trace.Request
Synopsis
Glacier2.Server.Trace.Request=num
Description
If num
is set to a value larger than 0, the Glacier2 router logs a trace message for each request that is forwarded from a server. The default value is 0
.
Glacier2.SessionManager
Synopsis
Glacier2.SessionManager=proxy
Description
Specifies the proxy of an object that implements the Glacier2::SessionManager
interface. The router invokes this proxy to create a new session for a client, but only after the router validates the client's user name and password.
As a proxy property, you can configure additional aspects of the proxy using properties.
Glacier2.SessionTimeout
Synopsis
Glacier2.SessionTimeout=num
Description
If num
is set to a value larger than 0, a client's session with the Glacier2 router expires after the specified num
seconds of inactivity. The default value is 0
, meaning sessions do not expire due to inactivity.
It is important to choose num
such that client sessions do not expire prematurely.
The session timeout may also affect Active Connection Management (ACM) for client connections, which are connections to the router's object adapter named Glacier2.Client
. If you have not explicitly configured the router with a value for Glacier2.Client.ACM.Timeout
, the router uses the session timeout as the value for this property. If no session timeout is defined, the router's incoming client connections use its default ACM behavior.
Glacier2.SSLPermissionsVerifier
Synopsis
Glacier2.SSLPermissionsVerifier=proxy
Description
Specifies the proxy of an object that implements the Glacier2::SSLPermissionsVerifier
interface for controlling access to Glacier2 sessions. The router invokes this proxy to verify the credentials of clients that attempt to create a session from a secure connection. Sessions created with a user name and password are verified by the object specified in Glacier2.PermissionsVerifier
.
Glacier2 supplies a "null" permissions verifier object that accepts the credentials of any client for situations in which no authentication is necessary. To enable this verifier, set the property value to instance/NullSSLPermissionsVerifier
, where instance
is the value of Glacier2.InstanceName
.
As a proxy property, you can configure additional aspects of the proxy using properties.
Glacier2.SSLSessionManager
Synopsis
Glacier2.SSLSessionManager=proxy
Description
Specifies the proxy of an object that implements the Glacier2::SSLSessionManager
interface for managing sessions. The router invokes this proxy to create a new session for a client that has called createSessionFromSecureConnection
.
As a proxy property, you can configure additional aspects of the proxy using properties.
Glacier2.Trace.RoutingTable
Synopsis
Glacier2.Trace.RoutingTable=num
Description
The routing table trace level:
0 | No routing table trace (default). |
1 | Logs a message for each proxy that is added to the routing table. |
2 | Logs a message for each proxy that is evicted from the routing table (see |
3 | Combines the output for trace levels 1 and 2. |
Glacier2.Trace.Session
Synopsis
Glacier2.Trace.Session=num
Description
If num
is set to a value larger than 0, the Glacier2 router logs trace messages about session-related activities. The default value is 0
.
