Operating Systems Solaris How to enable ping?a litte complex Post 303015700 by stomp on Tuesday 10th of April 2018 11:36:35 AM

Code:
17:14:52.804665 IP 192.168.0.2 > 10.2.0.1: ICMP echo request, id 15645, seq 1, length 64 
17:14:52.806881 IP 192.168.0.30 > 192.168.0.2: ICMP echo reply, id 15645, seq 1, length 64 
17:14:52.807016 IP 192.168.0.2 > 192.168.0.30: ICMP host 192.168.0.2 unreachable - admin prohibited, length 92

Well that shows pretty obvious, what's going on:
  • The icmp echo request goes out to the target
  • The icmp echo reply comes back from the target
  • The local host rejects the echo reply and sends itself another icmp message for the failed echo reply

So this points to your client machine, sending the ping, that the paket filter is configured wrongly.

Please show the current rules as requested in my previous post(iptables -L -v- n).

When you execute your ping, and watch the counters with the above given watch command, which rules seem to match for the icmp packages?

oidentd_masq.conf(5)						File Formats Manual					      oidentd_masq.conf(5)

NAME
oidentd_masq.conf - oidentd IP masquerading/NAT configuration file. DESCRIPTION
If you are using IP masquerading or NAT, oidentd can optionally return a username for connections from other machines. Support for this is specified by calling oidentd with the -m (or --masq) flag and by creating an /etc/oidentd_masq.conf file. oidentd can also forward requests for an IP masqueraded connection to the machine from which connection originates by way of the -f option. This will only work if the host to which the connection is forwarded is running oidentd with the -P (proxy) flag, or if the host's ident daemon will return a valid reply regardless of the input supplied by and the address of the host requesting the info (some ident daemons for windows do this, maybe others). FORMAT
<IP Address|Hostname>[/<Mask>] <Ident Response> <System Type> The first field contains the IP address or the hostname of a machine that IP masquerades through the machine on which oidentd runs. The mask parameter can be either a network mask or a mask in CIDR notation. A mask of 24 is equivalent to 255.255.255.0, a mask of 16 is equivalent to 255.255.0.0, etc. The second field specifies the reply that oidentd will return for lookups to the host matching the IP address specified in the first param- eter. The third field specifies the operating system the machine matching the first parameter is running. EXAMPLES
<Host>[/<Mask>] <Ident Response> <System Type> 192.168.1.1 someone UNIX 192.168.1.2 noone WINDOWS 192.168.1.1/32 user1 UNIX 192.168.1.0/24 user3 UNIX 192.168.0.0/16 user4 UNIX somehost user5 UNIX 192.168.1.0/255.255.255.0 user6 UNIX AUTHOR
