Hi,
I have inherited an application which is demanding the same UDP port as NFS,
NFS uses the first available ports at boot;
rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 32768 status
100024 1 tcp 32768 status
100021 1 udp 32769 nlockmgr
100021 3 udp 32769 nlockmgr
100021 4 udp 32769 nlockmgr
391002 2 tcp 32769 sgi_fam
The app I have starts with the following error; and the port allocation
cannot be changed for this app.
ERROR binding port : 32768
ERROR: Error while running rrcp daemon:
rrcpW_InetSocket : failed to bind() inet address, (errno=98).
Maybe a similar instance of rrcpd is already running
On Solaris8 this can be resolved by adding the following to a start script
in rc2.d
/usr/sbin/ndd -set /dev/udp udp_smallest_anon_port 32800
But Linux does not support ndd
After looking about for a while I found
/proc/sys/net/ipv4/ip_local_port_range
which would appear to allow you to set this range but each time I modify the
file and reboot the file gets changed back !
Any ideas or pointers as to how I could make this change permanent would be
greatly appreciated.
Thanks in advance,
Richard
