These guys were doing all kinds of stuff along those lines http://www.bawug.org/ Specifically - Long Range 802.11b Links http://www.bawug.org/howto/pres/20010503/ There are lots of ways to go about it. I believe there is info on other ways on that same site. I am still looking into proprietary wireless WAN device manufacturers, for some of my own needs. If anyone has any recommendations. Also depending on how often the links to go, not sure if you want to do manual re-routing or have that be automated.

Sanitize tcpdump packet capture
Hi everyone, I'm currently in the position where I need to send a tcpdump packet capture off to the vendor for support. Before I do that I need to sanitize the binary capture by changing/removing the IP addresses as well as hopefully the MAC addresses and packet content. I need to keep track of the TCP options however. I looked at tcpdpriv and sanitize. The first doesn't want to compile easily and the second doesn't appear to meet my requirments. Can anyone point me to a tool that accomplishes what I want ? Thanks, Glen PS: If you happen to know why SLES 9 seems to ignore the MSS requested by the client in the initial TCP handshake then that would be helpful as well :)

Re: Sanitize tcpdump packet capture
also, look at 'tcprewrite' (comes as part of tcpreplay). It can simply replace IP addresses in your IP headers. 'netsed' will help you with content (e.g. domain names in DNS requests). Don't forget to with the checksums once you are done. I find that 'netdude' has become very hard to install on modern systems due to issues with gcc 3 and newer libpcaps(Continue reading). But if you get it installed, go with it.

weird mail issue
I had my main mail server memory and I finally recovered this morning. my problem is that now all of a sudden inbound messages are queueing up and not actually going anywhere. I am getting the following in the mailq output: 50BBB5D8016 2254 Wed Sep 6 09:35:47 solid@... (connect to mail.fditech.net[/var/imap/socket/lmtp]: Connection refused) otheruser@... aliasofotheruser@... Why am I all of a sudden having problems with lmtp? The documentation is sparse on this so if anyone has any ideas, I'd love to hear them. -- Cheers, Matt Young solid@... GPG Public Key: http://youngdev.net/?page=gpg

If it is running, make sure that it is set to utilize /var/imap/socket/lmtp as it's socket location. /etc/cyrus.conf should have a line like so: lmtpunix cmd="lmtpd" listen="/var/imap/socket/lmtp" prefork=0 -- -- -Riskable http://www.riskable.com "I have a license to kill -9" GPG Key: http://riskable.com/r.asc

Re: weird mail issue
I verified that the line you mentioned is there. I have new information. Now my mailq command is returning the following: 8DE3B53905F 2235 Wed Sep 6 11:58:47 solid@... (conversation with mail.fditech.net[/var/imap/socket/lmtp] timed out while receiving the initial server greeting) otheruser@... aliasforotheruser@... also I cannot login via thunderbird, squirrelmail or 'cyradm -u cyrus localhost'. the connections time out.
