time lag between /sbin/ifconfig eth2 up and when interface becomes usable...
by Gautam Thaker 05 May '08

05 May '08

Hi: I realize this question may not be fedora specific but here it is. I am trying to determine how soon after a /sbin/ifconfig eth2 up 192.168.0.2 can I actually successfully send UDP packets out that interface. (UDP since i wanted to keep things simple, not TCP flow/congestion control entanglements.) I have a loop such as: #!/usr/bin/perl -w $utime = $ARGV[0]; while(1) { system "usleep $utime"; system "/sbin/ifconfig eth2 down"; system "date"; print "after eth2 down\n"; system "usleep $utime"; system "/sbin/ifconfig eth2 up 192.168.0.2"; system "date"; print "after eth2 up\n"; } From my tests it appears that it takes between 4 to 6 seconds after the "up" command before my UDP packets actually start going out. The tests are between two machines with addresses 192.168.0.2 <---> 192.168.0.3. Any hints welcome. The "/sbin/ifconfig eth2 up 192.168.0.2" command returns right away, but the interface is not ready to go for a few seconds. What can this be due to? Gautam

sysadmin probs; help needed
by Tom Poe 05 May '08

05 May '08

I started to register and try out freeworlddialup.com . It said to download softphone "communicator" and ... well, it was a .exe file. First red flag. The screen said enter user info, so I enter my user name, tom. Guess what? The app froze, I decided I didn't like this .exe thing, and restarted computer. Now, when I bring up network dialog, which requires root privileges, it won't accept root password, but will accept user tom's password. I need to correct this. Suggestions? Thanks, Tom

Getting access out through gateway
by Simon Slater 04 May '08

04 May '08

G'day everyone, Here is a problem I've struggled with for some time now and have run out of ideas. Hopefully someone can point me in the right direction. An acer laptop with F8 needs updating and has internet access via a dialup connection to a box running FC6. Running Wireshark on the laptop when a connection with Firefox is attempted shows the gateway returning a packet with: ICMP Destination unreachable (Host administratively prohibited). This points to a REJECT target in the iptables, of which there is only one. Yet with iptables stopped, there is still no connection, with the gateway returning a packet with TCP flags: [RST, ACK]. Is the problem with the laptop or the gateway box? Here are the iptables rules. [root@Ipex ~]# iptables -L -t nat Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination MASQUERADE all -- anywhere anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@Ipex ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere Chain FORWARD (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere ACCEPT all -- 192.168.0.0/24 anywhere ACCEPT all -- anywhere 192.168.0.0/24 DROP all -- !192.168.0.0/24 anywhere Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain RH-Firewall-1-INPUT (2 references) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT icmp -- anywhere anywhere icmp any ACCEPT esp -- anywhere anywhere ACCEPT ah -- anywhere anywhere ACCEPT udp -- anywhere 224.0.0.251 udp dpt:mdns ACCEPT udp -- anywhere anywhere udp dpt:ipp ACCEPT tcp -- anywhere anywhere tcp dpt:ipp ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:nfs ACCEPT udp -- anywhere anywhere state NEW udp dpt:netbios-ns ACCEPT udp -- anywhere anywhere state NEW udp dpt:netbios-dgm ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:netbios-ssn ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:microsoft-ds REJECT all -- anywhere anywhere reject-with icmp-host-prohibited [root@Ipex ~]# All suggestions eagerly and gratefully anticipated. -- 'ooroo Simon Registered Linux User #463789.
