22_oct_17_mon 19.35.utc howdy , folks ; long time , no post . why ? because , when compared to 20 - 40 years ago , when i --loved-- it , email has become the most_royal of pains to use . please forgive this brief digression ; it is relevant . i spent 6 hours , yesterday , typing a detailed account of the symptoms and the eventual identification of that which i believe to be the actual problem with my isp's dhcp server . when sending , i got the password wrong [ correct chars , wrong order ] . believing that i was closing the dialog_box for the password , i closed the composition window . after wrestling w/ thunderbird for an hour w/o finding the message , i resorted to the tried_and_true bsd approach ; with hd and vi , i found , finally , a copy in a file called "Sent" . because the email was never sent , this is the exact place in which to save it . i believe that the jargon for this characteristic is "feature" . ok ; so , i did not lose the 6 hours of typing [ whew ! ] . i copied the relevant lines from "Sent" into its own file . --but-- , for the life of me , i can not get thunderbird to bring this file into a new composition window , except as an "attachment" [ which i can not see ] . iirc , email_"attachment"s are strongly discouraged on this list . so , it is --not-- included w/ this post . how_ever , i could be wrong . if it --is-- permissible to do so , then i will be happy to send it w/ a subsequent post . here is the abridged version of my problem . i have built backup_hardware for my gateway box . in the event of a hardware failure , a] power_down failed_box , b] detach cables , c] swap boxen , d] attach cables , e] power_up good_box w/ auto_boot w/ dhclient . during the testing of the new box , i have found that the isp's dhcp server returns an address which works only partially or not_at_all [ it is a different address , always ; should it be ? ] . because the existing box has not failed , ifconfig tells me its real identity . if i use , manually , the "add" form of the ifconfig command , with this address , then , suddenly , everything works perfectly . --but-- , i did this manually , not by using dhcp . i must assume that i do not know the prior address . the handbook and various man_pages discuss , at length , the case of a roving lap_top , w/ multiple isps . in this case , i have multiple clients and a constant isp ; this is not discussed . is there a way for my client to persuade the isp's server to "bind" my client to an address which the isp will accept ? what is the etiquette regarding email_"attachment"s in postings to this list ? is there a way to get a text_file [ perhaps , created w/ vi ] into a thunderbird composition window ? tia rob
