tcp_tw_recycle missing

[Danik]

was using in proxmox 3 - openvz tcp_tw_recycle option
after migrating to proxmox 5 trying to enable same option on a host machine without success

> sysctl: cannot stat /proc/sys/net/ipv4/tcp_tw_recycle: No such file or directory

using pve-manager/5.1-36/131401db (running kernel: 4.13.4-1-pve)

is there any option ho to enable it ?

 

[Danik]

on proxmox version
> pve-manager/5.0-32/2560e073 (running kernel: 4.10.17-3-pve)

this option working ok

> net.ipv4.tcp_tw_recycle = 1

 

[Danik]

found out that this option was removed from kernel 4.12 and up

That's not a bad thing. OSX devices behind a NAT firewall had issues talking to servers with recycle enabled.
