Hi, Vincent! Thank you for explanation, I was not aware of snmp_select_info2. I noticed that NetSNMP agent startup routine opens some filehandles right after start and then using them to handle queries. This means that even if keepalived opens many filehandles during its lifetime, the SNMP ones would have numbers less than 20, so the select interface would be sufficient for a typical usage. 18.08.2015 10:56, Vincent Bernat пишет: > You seem to have gotten it right.

Of course, this is "recent" (not > really, but Debian-based distributions got stuck in 5.4 for a long > time), so you have to support both. -- Best regards, Alexey ------------------------------------------------------------------------------ _______________________________________________ Keepalived-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/keepalived-devel
