Thank you . How can I distinguish which package is missing from my CentOS
server and try to just add it (rather than trying for a fresh CentOS
re-installation) ? On another machine similar to mine , the output is as :
# netstat -ant |grep 4965
tcp        0      0 0.0.0.0:4965            0.0.0.0:*               LISTEN
# netstat -anp |grep 4965
tcp        0      0 0.0.0.0:4965            0.0.0.0:*
LISTEN      1090/iptrans
# lsof -i |grep 4965
iptrans    1090 root   21u  IPv4       1764       TCP *:4965 (LISTEN)
On that machine , the 'telnet ip-addr 4965' can get through . So which
package do I need to add to mine ?
