Spacewalk 錯誤：jabberd/c2s[4642]：不存在的主機的 SASL 回呼：abcd

我在 CentOS Linux 版本 7.4.1708（核心）上運行 spacewalk 2.6

並在開始太空行走時使用 spacewalk-service start

我觀察到：

jabberd.service - Jabber Server
   Loaded: loaded (/usr/lib/systemd/system/jabberd.service; enabled; vendor preset: disabled)
   Active: active (exited) since Wed 2018-02-28 16:24:06 UTC; 7h ago

 Main PID: 4644 (code=exited, status=0/SUCCESS)
   Memory: 0B

經過進一步調查和谷歌搜索

現在 spacewalk.abc 似乎是一個 aws 負載平衡器：

$nslookup spacewalk.a.b.c
Server:         1x.xx.xxx.80
Address:        1x.xx.1xx.80#53

spacewalk.a.b.c canonical name = internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com.
Name:   internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com

Name:   internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com
Address: 1x.1xx.1xx.82

我搜尋了論壇和博客，但找不到此 jabberd 未啟動的解決方案

--------------- 回覆@tukan ------------------------------- - ----

jabberd 啟動時實際上執行了 6 個程式。它們的可執行檔位於以下位置：

1. /usr/bin/c2s 
2. /usr/bin/jabberd 
3. /usr/bin/resolver 
4. /usr/bin/router 
5. /usr/bin/s2s 
6. /usr/bin/sm

jabberd configuration:

1. /usr/bin/c2s -c /etc/jabberd/c2s.xml        https://pastebin.com/A1Qp44qp
2. /usr/bin/jabberd itself does not have a config ??
3. /usr/bin/sm -c /etc/jabberd/sm.xml          https://pastebin.com/4gi4MR3g
4. /usr/bin/router -c /etc/jabberd/router.xml  https://pastebin.com/cdRZqk5D
5. /usr/bin/s2s -c /etc/jabberd/s2s.xml        https://pastebin.com/nPsMsde3
6. /usr/bin/sm -c /etc/jabberd/sm.xml          https://pastebin.com/s7vQu3VE

c2s and sm are configured to encrypt information that passes through them. The cert and key used to do this are located in the /etc/jabberd/server.pem file.

感謝您的配置。你的配置對我來說看起來不錯。您的設定檔中只有小寫字母。

我認為您仍然可能會遇到大寫主機名稱：

internal-GSS-Spacewalk-123456789.us-east

因為你nslookup的名字中的字母都是大寫的

$nslookup spacewalk.abc 伺服器：1x.xx.xxx.80 位址：
1x.xx.1xx.80#53

spacewalk.abc 規範名稱 = inside-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com。名稱：
internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws.com 地址：1x.1xx.1xx.55 名稱：
internal-GSS-Spacewalk-123456789.us-east-1.elb.amazonaws。 com地址：1x.1xx.1xx.82

嘗試將您的 FQDN 全部小寫，它應該開始工作。我現在在手機上寫作，稍後當我在筆記本上時我會填寫參考文獻。

編輯正如所承諾的，這裡是來源：

如果主機名稱包含大小寫，則 jabberd 和 osad/osa-dispatcher 之間的通訊失敗

去引用：

“切勿在 Satellite 主機名稱中使用大寫字母，這樣根本行不通！”

在 CentOS7 上安裝 Spacewalk 時出現問題（全新安裝）

儘管聽起來很奇怪，但您絕對不應該在主機名稱中使用大寫字母！
