Socket error 11001 host not found что за ошибка

Socket error 11001 host not found что за ошибка

This means that the ISP POP3 or SMTP server which you have told VPOP3 to connect to does not currently exist. This might be that you have mistyped the server address, or that your ISP is having temporary problems, or that you are using an internal DNS server or proxy which is either slow or not configured correctly.

The first thing to do is to go to the VPOP3 settings, then External Mail → In Mail (if the error is a ‘POP3 Client Error’) or Out Mail (if the error is an ‘SMTP Client Error’), and check the server addresses are correct — contact your ISP if you are not sure.

Also, try PINGing the server addresses from a DOS prompt on the VPOP3 computer — this will show if Windows on that PC is able to resolve the server names to numeric IP addresses correctly.

Этот хост неизвестен. Ошибка Windows Sockets — 11001

При подключении к базе, расположенной на сервере 1С:Предприятия, возникает ошибка "…Windows Sockets — 11001 (0x00002AF9). Этот хост неизвестен…". Как вылечить?

Ошибка подключения к базе, расположенной на сервере 1С:Предприятия, возникает не всегда!
Подключение из Windows XP обычно проходит без особых проблем, при этом аналогичное подключение из Windows 7 может завершаться аварийно:
Ошибка 11001 — Windows Sockets
Лечится эта ошибка довольно просто! Достаточно внести изменения в файл hosts

Файл hosts представляет собой
Обычный текстовый файл (не имеющий расширения). В hosts-файле по умолчанию прописан всего один IP-адрес (127.0.0.1), зарезервированный для localhost, то есть для локального ПК. Файл hosts представляет собой обычный текстовый файл (не имеющий расширения).

Где находится файл hosts
• Windows 95/98/ME – WINDOWS;
• Windows NT/2000/XP/Vista/7 – Windows/System32/drivers/etc.

И так у нас Win7 открываем C:\WINDOWS\system32\drivers\etc\hosts, и добавляем в него ip-адрес вашего сервера.
Например так:
192.168.1.100 sermac

Socket error #11001: Host not found

An address book is a place where you can keep and organize your remote connections. Each connection represents a specific remote computer. Connections have properties such as the destination address, access password (if saved), color depth and so on.

Remote Utilities allows you to back up and encrypt your address books stored locally.

The Host is a remote module installed on a target (i.e. remote) PC. This module works for both unattended and attended access.

Agent

Agent is a remote module for spontaneous-only support. The Agent displays its own window that can be branded with your custom logo and text. Agent doesn’t require installation and administrative privileges to run.

Internet-ID connection

An Internet-ID connection uses an intermediary server on the Web («Internet-ID server») to broker a remote connection between Viewer and Host.

Symptoms

• Remote computer status is shown as «Offline» in the Viewer address book .
• You can establish a remote connection, but the connection is unstable.

When you examine the Host log (or Agent log, if Agent is used) you see the following error: Socket Error # 11001 Host not found.(EIdSocketError)

Cause

• DNS problem, i.e. the IP address of the intermediate server cannot be resolved from its DNS name.
• The intermediate server address or outbound port are blocked by the firewall.

WSAHOST_NOT_FOUND
11001
Host not found.
No such host is known. The name is not an official host name or alias, or it cannot be found in the database(s) being queried. This error may also be returned for protocol and service queries, and means that the specified name could not be found in the relevant database.

Solution 1: Clear the DNS cache

1. Press Win+R to open the Run dialog.
2. Type ipconfig /flushdns and click OK (or press Enter) to clear the DNS cache:
3. Right click on the Host icon in the tray area and select Restart Host. Wait 10-20 seconds until the Host restarts and connects back to the intermediate server.

Solution 2: Check connectivity with our public server

If you use our public Internet-ID service make sure that the primary server at id.remoteutilities.com can be accessed from the Host PC and the IP address of the server can be resolved successfully.

1. Press Win+R to open the Run dialog.
2. Type cmd and click OK (or press Enter). The Command Prompt will open.
3. Type ping id.remoteutilities.com and press Enter.
4. If the ping command and DNS resolution are successful, the result will be shown in the CMD window:
5. If you receive «Request timed out» as a response, the ID server cannot be reached from the Host location. Please, contact your system administrator.

Solution 3: Make sure outbound connection is allowed

Even if outbound connections on TCP ports 5655 and 443 are allowed on the Host machine and in the perimeter firewall, such connections may still be blocked on the ISP level. In this case you should contact your ISP representative.

11001 returned on all calls to getaddrinfo()

Having an issue connecting to a device on my network. Whenever I call getaddrinfo() it returns 11001. I have checked this with numerous different IP’s in the IP_ADDRESS string (Global Var). I’ve checked all the non-working numbers with nslookup, and most exist there.

getaddrinfo-returns-always-11001-host-not-found seems to be asking a similar question, but there’s no answer there.

At the moment, my code is not even trying to connect to the remote device, just trying to resolve an IP. Once that works I can move on to bigger and messier problems.

Most of this code has been taken lock and stock from the msdn website, but it all seems to look ok.
