# yum search libpcap-devel Loaded plugins: product-id, rhnplugin, search-disabled-repos, security, subscription-manager This system is receiving updates from RHN Classic or RHN Satellite. Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Warning: No matches found for: libpcap-devel No Matches found
解决scheme似乎在这里： https : //access.redhat.com/solutions/57913，但我没有访问..
你能告诉我如何解决这个问题吗？
libpcap-devel位于RHEL可选通道中，您需要在系统上启用该通道。
如果您无法访问RHEL文档，则需要与贵公司的负责人联系，以获得授权访问您的Red Hat帐户。
拼出迈克尔的答案：
sudo yum-config-manager --enable rhel-6-server-optional-rpms sudo yum install libpcap-devel sudo yum-config-manager --disable rhel-6-server-optional-rpms
或者你可以编辑/etc/yum.repos.d/redhat.repo：
[rhel-6-server-optional-rpms] name = Red Hat Enterprise Linux 6 Server - Optional (RPMs) baseurl = https://cdn.redhat.com/content/dist/rhel/server/6/$releasever/$basearch/optional/os enabled = 1
