Chapter 14   Proxy Error Log Messages

This chapter defines some of the errors the proxy commonly reports. They are listed alphabetically by the words of the message. The errors are categorized also by severity.

The categories of severity for proxy server error log messages are:

  • Catastrophe is a fatal error, a software crash, or other serious error that causes the client to receive no service, partial service, or totally invalid service.

  • Failure means something failed, the proxy handled the error, but the error may still cause the proxy to function improperly or to fail to process a request.

  • Inform is an informational log entry.

  • Misconfig means something was misconfigured in a configuration source such as magnus.conf or obj.conf.

  • Warning flags something that could be a normal operational error, but may also be a more serious error such as misconfiguration (e.g., host unreachable).

Proxy Error Messages

The following errors are those that commonly appear in the proxy server's error log and the Windows NT Event Viewer.


Service Startup Failure

SOCKS Error Messages

The SOCKS log file contains both error and access messages. The following are the error messages that may appear in this log.

fatal: error in config file

The configuration file had one or more errors (listed earlier in the log file) that made it futile to start up the SOCKS server

fatal: can't create listening socket

A TCP socket could not be created.

fatal: can't bind to socks port

Another application or daemon is using the SOCKS port.

fatal: can't listen at socket

An internal error occurred during startup.

error: unknown request type 0x0D from host name:port number

Someone tried to use the SOCKS server for something that does not use the SOCKS protocol.

error: auth: can't open password file /etc/filename !

The specified password file does not exist.

error: illegal route: route

The route specified in the configuration file isn't a valid IP address or interface.

error: unknown field in config: text

Something in the configuration file unrecognized.

error: can't open config file '/etc/filename'

The SOCKS server cannotcannot open the specified configuration file.

error: ldap: can't authenticate to server (specific reason)

The bind DN or password was rejected by the LDAP server.

error: ldap: can't connect to servername:port

The specified LDAP server did not answer.

error: ldap: failed LDAP close (specific reason)

The SOCKS server could not close the connection to the LDAP server

error: ldap: server is down -- turning off LDAP auth

The LDAP server has vanished and ns-sockd cannot get in touch with it. ns-sockd will try to contact the LDAP server every few minutes, and once it is contacted, will enable LDAP authentication.

warning: ident: request from host name:port number is some text

The RFC 1413 ident response from that client was some text, not the user name

warning: auth: user user name tried to auth as user name

The user tried to authenticate as a user name even though the ident response was another user name

warning: socks4 request from host name:port number can't authenticate

The configuration file specifies that user name/password authentication is required for this connection. However, the client is using SOCKS4 and cannot authenticate that way. Thus, the client's request is denied and the SOCKS server logs a warning.

warning: request from host name:port number arrived via bad route!

A request arrived from the wrong interface meaning that someone is spoofing an IP address, or the route information in the configuration file is wrong.

warning: request from host name:port number failed ident check

The client did not send the required ident response, so the connection was dropped.

warning: passwd file: line number is bad

The format of the SOCKS5 password file is incorrect at or near the specified line.
