These patches implement a tool that can be used to read and write the
sysfs files, with subcommands!
The following subcommands are implemented:
rpcctl client
rpcctl client show
rpcctl switch
rpcctl switch set
rpcctl switch show
rpcctl xprt
rpcctl xprt remove
rpcctl xprt set
rpcctl xprt show
So you can print out information about every switch with:
anna@client ~ % rpcctl switch
switch-0: xprts 1, active 1, queue 0
xprt-0: local, /var/run/gssproxy.sock [main]
switch-1: xprts 1, active 1, queue 0
xprt-1: local, /var/run/rpcbind.sock [main]
switch-2: xprts 1, active 1, queue 0
xprt-2: tcp, 192.168.111.1 [main]
switch-3: xprts 4, active 4, queue 0
xprt-3: tcp, 192.168.111.188 [main]
xprt-4: tcp, 192.168.111.188
xprt-5: tcp, 192.168.111.188
xprt-6: tcp, 192.168.111.188
And information about each xprt:
anna@client ~ % rpcctl xprt
xprt-0: local, /var/run/gssproxy.sock, port 0, state <CONNECTED,BOUND>, main
Source: (einval), port 0, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
xprt-1: local, /var/run/rpcbind.sock, port 0, state <CONNECTED,BOUND>, main
Source: (einval), port 0, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
xprt-2: tcp, 192.168.111.1, port 2049, state <CONNECTED,BOUND>, main
Source: 192.168.111.222, port 959, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
xprt-3: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>, main
Source: 192.168.111.222, port 921, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
xprt-4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
Source: 192.168.111.222, port 726, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
xprt-5: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
Source: 192.168.111.222, port 671, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
xprt-6: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
Source: 192.168.111.222, port 934, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
You can use the `set` subcommand to change the dstaddr of individual xprts:
anna@client ~ % sudo rpcctl xprt show xprt-4
xprt-4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
Source: 192.168.111.222, port 726, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
anna@client ~ % sudo rpcctl xprt set xprt-4 dstaddr server2.nowheycreamery.com
xprt-4: tcp, 192.168.111.186, port 2049, state <CONNECTED,BOUND>
Source: 192.168.111.222, port 726, Requests: 2
Congestion: cur 0, win 256, Slots: min 2, max 65536
Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
Or for changing the dstaddr of all xprts attached to a switch:
anna@client % rpcctl switch show switch-3
switch-3: xprts 4, active 4, queue 0
xprt 3: tcp, 192.168.111.188 [main]
xprt 4: tcp, 192.168.111.188
xprt 5: tcp, 192.168.111.188
xprt 6: tcp, 192.168.111.188
anna@client % sudo rpcctl switch set switch-3 dstaddr server2.nowheycreamery.vm
switch-3: xprts 4, active 4, queue 0
xprt 2: tcp, 192.168.111.186 [main]
xprt 3: tcp, 192.168.111.186
xprt 5: tcp, 192.168.111.186
xprt 6: tcp, 192.168.111.186
Changes in v8:
- Improved exception handling when running commands
- Completely rework argument and command parsing to be more like ip-link
- Completely rewrite the man page to reflect the new argument scheme and
add examples
- Only call socket.gethostbyname() once when changing the dstaddr of an
RPC switch
Thoughts?
